You Say Collision, I Say Allision; Let’s Sort the Whole Thing Out

Despite improved navigation aids, including charts and Global Positioning Systems (GPS), ships still have accidents in our nation’s waterways, and I regularly review notification reports of these accidents from the National Response Center. Sometimes I need to consult the old nautical dictionary I inherited from my grandfather (a lawyer and U.S. Navy captain) to figure out what they mean.

Nautical terms and marine salvage books.

Keeping it all straight. (NOAA)

The U.S. Coast Guard investigates ship accidents, but they use the terms “marine casualty or accident” interchangeably [PDF]. Mariners are required to report any occurrence involving a vessel that results in:

  • Grounding
  • Stranding
  • Foundering
  • Flooding
  • Collision
  • Allision
  • Explosion
  • Fire
  • Reduction or loss of a vessel’s electrical power, propulsion, or steering capabilities
  • Failures or occurrences, regardless of cause, which impair any aspect of a vessel’s operation, components, or cargo
  • Any other circumstance that might affect or impair a vessel’s seaworthiness, efficiency, or fitness for service or route
  • Any incident involving significant harm to the environment

Some of those terms are pretty straightforward, but what is the difference between grounding and stranding? Or foundering and flooding? And my favorite, collision and allision?

Here is my basic understanding of these terms, but I am sure that some of these could fill an admiralty law textbook.

Groundings and strandings are probably the most common types of marine casualties. A grounding is when a ship strikes the seabed, while a stranding is when the ship then remains there for some length of time. Both can damage a vessel and result in oil spills depending on the ocean bottom type (rocky, sandy, muddy?), sea conditions, and severity of the event (is the ship a little scraped or did it break open?).

Flooding means taking on excessive water in one or more of the spaces on a ship (e.g., the engine room), while foundering is basically taking on water to the point where the vessel becomes unstable and begins to sink or capsize. Note that “foundering” is different than “floundering,” which is to struggle or move aimlessly.

And collision and allision … These terms are sometimes used interchangeably, but technically, a collision is when two vessels strike each other, while an allision occurs when a vessel strikes a stationary object, such as a bridge or dock.

No matter the proper terminology, all of these incidents can result in spills, keeping us pollution responders on our toes because of the potential impacts to coasts, marine life, and habitats such as coral reefs and seagrass beds. But understanding these various nautical terms helps us understand the circumstances we’re dealing with in an emergency and better adapt our science-based recommendations as a result. And as my grandfather used to say, a collision at sea can ruin your entire day …

POSTED MARCH 25, 2014 | UPDATED MARCH 27, 2014 –The Saturday vessel collision in Galveston Bay (see “Vessel Collision and Spill in Galveston Bay”) that resulted in an oil spill of approximately 168,000 gallons, caused the closure of the heavily trafficked Port of Houston for 3 days. The Houston Ship Channel is now open, with some restrictions. There is a safety zone in effect in cleanup areas.

As predicted, strong southerly winds stranded much of the offshore oil overnight in the Matagorda region and these onshore winds are expected to bring ashore the remaining floating oil off Matagorda Island by Friday morning. Closer to the collision site, there have been very few new reports of remaining floating oil in Galveston Bay or offshore Galveston Island. However, new shoreline impacts may still be occurring in those areas due to re-mobilization of stranded oil or remaining scattered sheens and tarballs.

NOAA is providing scientific support to the U.S. Coast Guard, including trajectory forecasts of the floating oil movement, shoreline assessment, information management, overflight tracking of the oil, weather forecasts, and natural and economic resources at risk. Marine mammal and turtle stranding network personnel are responding. The NOAA Weather Service Incident Meteorologist is on-scene, as are additional NOAA personnel. Natural resource damage assessment personnel are at Galveston Bay and are initiating preassessment activities. The preassessment period is an on-scene evaluation of what the type of oil is, where it has gone, where it may be going and what resources are or may be at risk.

On March 22, 2014, at approximately 12:30 pm, the 585 foot bulk carrier M/V Summer Wind collided with the oil tank-barge Kirby 27706. The incident occurred in Galveston Bay near Texas City, Texas. The barge contained approximately 1,000,000 gallons of intermediate fuel oil in multiple tanks.

The #2 starboard tank was punctured, spilling approximately 168,000 gallons of oil. The barge is aground and the remaining oil was lightered (removed) late Sunday. The M/V Summer Wind is stable and not leaking oil. As of March 23, the Houston Ship Channel and Intracoastal Waterway was closed to traffic, including ferries and cruise ships. U.S. Coast Guard, NOAA, U.S. Fish and Wildlife Service, the Texas General Land Office and other agencies are responding.

Expected Behavior of the Spilled Oil

Intermediate fuel oils are produced by blending heavy residual oils with a light oil to meet specifications for viscosity and pour point. Their behavior can be summarized as follows:

  • IFO-380 will usually spread into thick slicks which can contain large amounts of oil. Oil recovery by skimmers and vacuum pumps can be very effective, particularly early in the spill.
  • Very little of this is likely to mix into the water column. It can form thick streamers or, under strong wind conditions, break into patches and tarballs.
  • IFO-380 is a persistent oil; only a relatively small amount is expected to evaporate within the first hours of a spill. Thus, spilled oil can be carried long distances by winds and currents.
  • IFO-380 can be very viscous and sticky, meaning that stranded oil tends to remain on the surface rather than penetrate sediments. Light accumulations usually form a “bath-tub ring” at the high-water line; heavy accumulations can pool on the surface.
  • Floating oil could potentially sink once it strands on the shoreline, picks up sediment, and then is eroded by wave action.

The incident occurred just inside the entrance of Galveston Bay. Northeasterly winds are expected to carry the oil out of the Bay, but onshore winds expected midweek could bring the oil back along the ocean beaches. The oil, likely in the form of tarballs, could be spread over a large section of ocean beaches.

Mapping the Problem After Owners Abandon Ship

This is a post by LTJG Alice Drury of the Office of Response and Restoration’s Emergency Response Division.

One of the largest vessel removal efforts in Washington history was a former Navy Liberty Ship, the Davy Crockett. In 2011 the Davy Crockett, previously abandoned by its owner on the Washington shore of the Columbia River, began leaking oil and sinking due to improper and unpermitted salvage operations. Its cleanup and removal cost $22 million dollars, and the owner was fined $405,000 by the Washington Department of Ecology and sentenced to four months in jail by the U.S. Attorney, Western District of Washington.

As I’ve mentioned before, derelict and abandoned vessels like the Davy Crockett are a nationwide problem that is expensive to deal with properly and, if the vessels are left to deteriorate, can cause significant environmental impacts. Unfortunately Washington’s Puget Sound is no exception to this issue.

Agency Collaboration

I’m part of the Derelict Vessel Task Force led by U.S. Coast Guard Sector Puget Sound. Made up of federal, state, and local agencies, this task force aims to identify and remove imminent pollution and hazard-to-navigation threats from derelict vessels and barges within Puget Sound. Among these agencies there are different jurisdictions and enforcement mechanisms related to derelict vessels.

A key player is Washington’s Department of Natural Resources (WA DNR), which manages the state Derelict Vessel Removal Program (DVRP). The DVRP has limited funding for removal of priority vessels. Unfortunately, according to WA DNR [PDF], with the growing number and size of problem vessels, program funding can’t keep up with the rising removal and disposal costs. The backlog of vessels in need of removal continues to grow.

Keeping Track

I’m working with the NOAA Office of Response and Restoration’s Spatial Data Branch to enter this list of derelict vessels into ERMA®. ERMA is a NOAA online mapping tool that integrates both static and real-time data to support environmental planning and response operations. Right now the vessels are primarily tracked in the WA DNR DVRP database. By pulling this data into ERMA, the task force will not only be able to see the vessels displayed on a map but also make use of the various layers of environmental sensitivity data already within ERMA. The hope is that this can help with the prioritizing process and possibly eventually be used as a tool to raise awareness.

A view of Pacific Northwest ERMA, a NOAA online mapping tool which can bring together a variety of environmental and response data. Here, you can see the black dots where ports are located around Washington's Puget Sound as well as the colors indicating the shoreline's characteristics and vulnerability to oil.

However, there aren’t enough resources within the Derelict Vessel Task Force to gather and continue to track (as the vessels can move) all the data needed in order to map the vessels accurately in ERMA. As a result, the task force is turning to local partners in order to help capture data.

Reaching Out

One such partner is the local Coast Guard Auxiliary Flotillas, a group of dedicated civilians helping the Coast Guard promote safety and security for citizens, ports, and waterways. In order to garner support for data-gathering, I recently attended the USCG Auxiliary Flotilla Seattle-Elliott Bay meeting, along with members of the local Coast Guard Incident Management Division who head the Puget Sound Derelict Vessel Task Force.

I spoke about a few local derelict vessel incidents and their impacts to the environment. I also showed how ERMA can be a powerful tool for displaying and prioritizing this information—if we can get the basic data that’s missing. As a result, this Flotilla will follow up with my Coast Guard colleagues and start collecting missing information on derelict and abandoned vessels on behalf of the Coast Guard and WA DNR.

Gathering data and displaying derelict vessels graphically is a small, but important, step on the way to solving the massive problem of derelict vessels. Once complete I hope that ERMA will be a powerful aid in displaying the issue and helping make decisions regarding derelict vessels in the Puget Sound. Stay tuned.

[Editor's Note: You can see a U.S. Coast Guard video of the start-to-finish process of removing the Davy Crockett from the Columbia River along with the Washington Department of Ecology's photos documenting the response.]

How Do You Solve a Problem Like Abandoned Ships?

This is a post by LTJG Alice Drury of the Office of Response and Restoration’s Emergency Response Division.

Two rusted ships partially sunk in water and surrounded by containment boom.

The old fishing vessel Helena Star has been allowed to become derelict, leaking oil and pulling down its neighboring vessel, the Golden West. (NOAA)

A rusted green hull, punched full of holes and tilted on its side, sits forlornly in the Hylebos Waterway of Tacoma, Washington. The dilapidated boat’s name, Helena Star, is partially obscured because the vessel is half sunk. The boat it is chained to, the equally rusted ship Golden West, is being drawn down into the waters with it. Bright yellow boom and a light sheen of oil surround the vessels. Meanwhile, the owners are nowhere in sight.

This is just one example of the nationwide problem of derelict vessels. These neglected ships often pose significant threats to fish, wildlife, and nearby habitat, in addition to becoming eyesores and hazards to navigation. Derelict vessels are a challenge to deal with properly because of ownership accountability issues, potential chemical and oil contamination, and the high cost of salvage and disposal. Only limited funds are available to deal with these types of vessels before they start sinking. In Washington’s Puget Sound alone, the NOAA Office of Response and Restoration’s Emergency Response Division has had several recent responses to derelict vessels that either sank or broke free of their moorings.

Many of these recent responses have come with colorful backstories, including a pair of retired Royal Canadian Navy vessels, a fishing boat that at one time housed the largest marijuana seizure by the U.S. Coast Guard (F/V Helena Star), the first American-designed and –built diesel tugboat (Tug Chickamauga), and the boat that carried author John Steinbeck and biologist Ed Ricketts on their famous trip through the Sea of Cortez (Western Flyer).

Unfortunately, all these vessels have met the end of their floating lives either through the deliberate action or negligence of their owners. Had the owners taken responsibility for maintaining them, the environmental impacts from leaked fuel, hazardous waste, and crushing impacts to the seabed could have been avoided, as well as the costly multi-agency response and removal operations that resulted.

heavy machinery is brought in to raise a sunken vessel from the sea floor.

In May 2012, the derelict fishing boat Deep Sea caught fire and sank near Washington’s Whidbey Island. The boat ended up leaking diesel fuel into waters near a Penn Cove Shellfish Company mussel farm, and the company took the precautionary measure of stopping the harvest. NOAA worked with them to sample mussels in the area for diesel contamination. Here, heavy machinery is brought in to raise the sunken vessel from the sea floor. (NOAA)

Yet there is hope that we can prevent these problems before they start. In Washington state there is momentum to combat the derelict vessel issue through measures to prevent boats from becoming derelict or environmental hazards, and by holding vessel owners accountable for what they own.

Washington State House bill 2457 is currently in the Washington State Legislature. Among other measures, the proposed bill:

  • “Establishes a fee on commercial moorage to fund the state’s derelict and abandoned vessel program.”
  • “Creates new penalties for failure to register a vessel.”

Additionally, Washington’s San Juan County is developing a new Derelict Vessel Prevention program, using a grant from the Puget Sound Partnership. San Juan County, a county composed of small rural Pacific Northwest islands, has a high number of derelict vessels [PDF]. This program is going to be used not only in San Juan County but throughout counties bordering Puget Sound.

On January 15, 2014, Washington’s Attorney General Bob Ferguson and Commissioner of Public Lands Peter Goldmark (who leads the Department of Natural Resources) announced the state was pursuing criminal charges against the owners of the Helena Star, which sank in Tacoma’s Hylebos Waterway, and the Tugboat Chickamauga, which sank in Eagle Harbor. Both vessels released oil and other pollutants when they sank.

It is an ongoing battle to hold accountable the owners of derelict and abandoned vessels and prevent them from causing problems in our nation’s waterways. Yet with cooperation, prevention, and increased accountability we can help manage the problem, and in the end reduce impacts to Washington’s cherished Puget Sound.

Protecting the Great Lakes After a Coal Ship Hits Ground in Lake Erie

The coal ship CSL Niagara got stuck in Lake Erie's soft, muddy bottom at the entrance to Sandusky Bay in November 2013.

In the course of a year, from October 2012 to October 2013, the Emergency Response Division of NOAA’s Office of Response and Restoration responded to 138 oil spills, chemical accidents, and various other threats to coastal environments and communities. Many of these responses required considerable time from the scientific team to estimate where spills might spread, analyze chemical hazards, and assess whether natural resources are at risk. Sometimes, however, we’re called into some incidents that end well, with minimum help needed on our part and no oil spilled.

Last November, LCDR John Lomnicky received a call from the U.S. Coast Guard with an example of an accident that had the potential to be much worse. LCDR Lomnicky is our Scientific Support Coordinator for the Great Lakes region and is based in Cleveland, Ohio.

When Staying Grounded Is a Bad Thing

On November 17, just after 10:00 in the morning, the vessel master of the CSL Niagara reported to the U.S. Coast Guard that his ship had run aground while leaving Sandusky Bay through Moseley Channel to Lake Erie. Aboard the ship were 33,000 metric tons (36,376 U.S. tons) of coal, headed to Hamilton, Ontario, and about 193 metric tons of intermediate fuel oil (a blend of gasoil and heavy fuel oil) and marine diesel. The concern in a situation like this would be that the grounded ship might leak oil. Its stern was stuck in the soft mud at the bottom of Lake Erie. At the time, the vessel master reported there were no injuries, flooding, or visible pollution.

This ship, the CSL Niagara, has a long history of transporting coal in Lake Erie. Launched in April of 1972 for Canada Steamship Lines, Ltd., the new ship was 730 feet long and even then was carrying coal to Hamilton, Ontario. During over 40 years of sailing in the Great Lakes, the Niagara has also carried cargos of grain, coke, stone, and iron ore.

Lake Erie has an average depth of 62 feet, but its western basin, where the CSL Niagara grounded, averages only 24 feet deep. (NOAA Chart)

Even though the vessel hadn’t released any oil, the Coast Guard Marine Safety Unit, who had responders at the scene very shortly after the accident, put in a call to the Office of Response and Restoration’s LCDR Lomnicky for scientific support. As a precaution, they requested that we model the trajectory of oil in a worst case scenario if 145 metric tons of intermediate fuel oil and 48 metric tons of diesel fuel were released all at once into the water. We also provided a prediction of when the lake’s lower-than-usual water level would return to normal so a salvage team could refloat the stuck vessel. After gathering all of this information for the Coast Guard, LCDR Lomnicky continued to stand by for further requests.

In the hours that followed the ship’s grounding, the winds grew stronger, hampering efforts to free the vessel. The wind was causing the water level in the lake to drop and NOAA’s National Weather Service in Detroit predicted a 7.5 foot drop in levels for western Lake Erie. By 8:30 p.m., with 30 knot winds in two-to-three foot seas, the three tugboats contracted by the ship’s owner to dislodge the Niagara were making some progress. By midnight, however, with weather conditions worsening, salvage operations were suspended and scheduled to resume at first light.

But the next morning, November 18, the water level had dropped another two feet, and the three tugs still had had no luck freeing the stern of the Niagara from the lake bottom. The ship’s owner was now working on plans for lightering (removing the fuel) and containing any potentially spilled oil. Fortunately, there were still no reports of damage to the vessel or oil discharged into the water. The ship was just stuck.

By 4:00 that afternoon the water conditions had improved and another attempt to free the vessel was planned. Also, a combined tug-barge was en route should lightering become necessary.

Later that evening, shortly after 10:00, the ship was pulled free by two of the tugs and was back on its way early the next morning.

Keeping the Great Lakes Great

Lake Erie is the shallowest of the five Great Lakes, with an average depth of 62 feet. Yet its western basin, where this ship grounding occurred, has an average depth of only 24 feet. The lake is an important source of commerce for both the U.S and Canada, who depend on it for shipping, fishing, and hydroelectric power. These industries place environmental pressure on the lake’s ecosystems, which  are also threatened by urban and agricultural runoff.

Happily, quick responders, sound information, and a break in the weather may have prevented this incident from becoming something much worse. A spill into Lake Erie could be devastating, especially considering its shallow waters, but this time, like many other times along the nation’s coasts, an oil spill was avoided.

Didn’t know that NOAA works in the Great Lakes? Nicknamed “the third coast,” the Great Lakes are a major U.S. water body, with a shoreline that stretches longer than the East Coast and Gulf Coast combined.

How Do Oil Spills Affect Coral Reefs?

Coral habitat in the Hawaiian Islands.

Coral habitat in the Hawaiian Islands. (NOAA)

A warming, more acidic ocean. Grounded ships and heavy fishing nets. Coral reefs face a lot of threats from humans. For these tiny animals that build their own limestone homes underwater, oil spills may add insult to injury.

But how does spilled oil reach coral reefs? And what are the effects?

How an oil spill affects corals depends on the species and maturity of the coral (e.g., early stages of life are very sensitive to oil) as well as the means and level of exposure to oil. Exposing corals to small amounts of oil for an extended period can be just as harmful as large amounts of oil for a brief time.

Coral reefs can come in contact with oil in three major ways:

  1. Oil floating on the water’s surface can be deposited directly on corals in an intertidal zone when the water level drops at low tide.
  2. Rough seas can mix lighter oil products into the water column (like shaking up a bottle of salad dressing), where they can drift down to coral reefs.
  3. As heavy oil weathers or gets mixed with sand or sediment, it can become dense enough to sink below the ocean surface and smother corals below.

Once oil comes into contact with corals, it can kill them or impede their reproduction, growth, behavior, and development. The entire reef ecosystem can suffer from an oil spill, affecting the many species of fish, crabs, and other marine invertebrates that live in and around coral reefs.

As oil spill responders, NOAA’s Office of Response and Restoration has to take these and many other factors into account during an oil spill near coral reefs. For example, if the spill resulted from a ship running aground on a reef, we need to consider the environmental impacts of the options for removing the ship. Or, if an oil spill occurred offshore but near coral reefs, we would advise the U.S. Coast Guard and other pollution responders to avoid using chemical dispersants to break up the oil spill because corals can be harmed by dispersed oil.

We also provide reports and information for responders and natural resource managers dealing with oil spills and coral reefs:

You can learn more about coral reefs, such as the basic biology of corals, how damaged coral reefs can recover from an oil spill or be restored after a ship grounding, and what we’ve learned about oil spills in tropical reefs.

For lessons a little closer to home, be sure to find out five more things you should know about coral reefs and listen to this podcast about threats to coral health from NOAA’s National Ocean Service.

At the Coast Guard Academy, Students Get a Dose of Real-World Response Tools

This is a post by the Office of Response and Restoration’s GIS Specialists Kari Sheets and Jay Coady.

The Office of Response and Restoration's Spatial Data Team introduces U.S. Coast Guard Academy cadets to ERMA, NOAA's online mapping tool for environmental response.

Students wearing crisp, blue uniforms lean in to get a better look at the map of the Gulf of Mexico being projected at the front of the small classroom.

Their normal Friday GIS class at the United States Coast Guard Academy in New London, Conn., has been taken over by two mapping specialists from NOAA’s Office of Response and Restoration. Kari Sheets and Jay Coady are standing in front of the classroom of cadets to introduce these future U.S. Coast Guard responders to an important tool they may use one day in the midst of a hurricane or oil spill response.

The tool is NOAA’s Environmental Response Management Application (ERMA®). ERMA is an online mapping tool that integrates both static and real-time data, such as ship locations, weather, and ocean currents, in a centralized, interactive map for environmental disaster response. Having all the latest information in an easy-to-use format provides environmental resource managers with the data they need to make informed decisions about where and how to deal with a pollution threat when it happens.  NOAA and the University of New Hampshire developed ERMA with the U.S. Coast Guard, U.S. Environmental Protection Agency, and the Department of Interior.

To the Classroom and Beyond

By offering training and collaboration opportunities like this early in cadets’ careers, NOAA and the Academy are providing future Coast Guard responders with the real-world knowledge and tools that they might encounter when addressing future pollution events.

One day this fall, Sheets and Coady taught three GIS classes that focused on ERMA, its capabilities, and how to use it once the cadets graduate from the Academy. The classes covered a general overview of the ERMA platform, how it fits in the Incident Command System structure, how it enables users to see and access data. They also included a live demonstration of the tool that highlighted recent data used in the response to Post Tropical Cyclone Sandy in 2012.

From Training to Explaining

The lesson also integrated data from a training exercise held from September 17-19, which simulated a tug-and-barge grounding and potential oil spill in Long Island Sound as part of the National Preparedness for Response Exercise Program (PREP).

The September 2013 training exercise, PREP, simulated a vessel grounding and oil spill in Long Island Sound. In the foreground, NOAA's Kari Sheets is checking metadata in ERMA while to her left, LT Sabrina Bateman and Cadet Jaimie Chicoine of the U.S. Coast Guard Academy look at spill trajectories in ERMA.

NOAA’s Sheets and Coady began working with the Academy over the summer in preparation for this exercise in Long Island Sound. Coast Guard Academy GIS instructor LT Sabrina Bateman and Cadet Jaimie Chicoine helped provide and add data and information into ERMA for the PREP exercise, where ERMA was designated the common operational picture (COP). As the COP during an incident, ERMA brings together various types of information, providing a single place to display up-to-date information that is also accessible to all individuals involved in incident response operations. This consistency and accessibility helps improve communication and coordination among responders and stakeholders.

The Academy was able to use ERMA to load selected data from their internal databases.  As a result of these early collaborations preparing for the drill, Sheets and Coady were invited to the Academy to guest lecture on ERMA for the GIS classes. The classes they taught went well, solidifying the Office of Response and Restoration’s connections with the Academy and resulting in an invitation back to teach again in the future.

In the meantime, LT Bateman plans on using ERMA in several of her GIS lectures and labs at the Academy to get cadets more accustomed to using it once they receive their assignments and enter Coast Guard stations around the country after graduation. This relationship has continued growing as the two organizations explore further opportunities for collaboration.

Above, Under, and Through the Ice: Demonstrating Technologies for Oil Spill Response in the Arctic

This is the third in a series of posts about Arctic Shield 2013 by the Office of Response and Restoration’s Zach Winters-Staszak. Read his first post, “Arctic-bound” and his second post, “Breaking Ice.”

76° N, 158° W marks the spot. The wind chill has dropped the mercury below zero as the U.S. Coast Guard Cutter Healy, an icebreaker, sits idly, anchored by the sea ice that dominates the landscape. All eyes are fixed on the brilliant orange of the Coast Guard zodiac, the small boat’s color contrasted against the cobalt blue water off the icebreaker’s port side. A faint hum of a motor gets louder and louder overhead as the “Puma” comes into view. Then, just as the miniature, remote-controlled aircraft is positioned exactly over a nearby patch of open water, the operator kills the motor and the Puma splashes down safely.

During the exercise Arctic Shield 2013, the U.S. Coast Guard Research and Development Center (RDC) brought a group of scientists and specialists together to demonstrate technologies that potentially could be used for oil spill response in the Arctic Ocean’s severe conditions. This is my third and final post detailing my experiences and involvement in the mission aboard the Healy; you can read the previous posts, “Arctic-bound” and “Breaking Ice.”

Existing Technology, New Applications

The Arctic Ocean remains a difficult to access and often dangerous environment.

Increased marine transportation and oil exploration in the Arctic increases the likelihood of, along with the responsibility to be prepared for, potential oil spills. Operating in an area as remote and ice-filled as the Arctic poses new logistical and tactical challenges for safe ship transit, search and rescue efforts, resource extraction, and oil spill response. For those of us working in oil spill response, this means developing new methods and technologies for surveying, assessing, and responding in these settings.

The RDC, coordinating efforts by the Unmanned Aircraft Systems (UAS) programs at the National Oceanic and Atmospheric Administration (NOAA) and the University of Alaska Fairbanks, demonstrated the Puma as one method to survey, identify, and monitor oil on and around the ice floes from above. The Puma is a battery-powered, aerial survey technology with military roots that is now being used for a variety of environmental applications.

The Puma’s advantages for oil spill response in the Arctic are many. With its capacity for high resolution and infrared imagery, the Puma could help identify and monitor oiled environments and wildlife during response efforts, while simultaneously creating a visual record of environmental injury that could be used during a Natural Resource Damage Assessment.

The NOAA Office of Response and Restoration’s Emergency Response Division has a long history of recording aerial imagery of oil spills by using trained observers aboard helicopters or airplanes to find and photograph oil on the water’s surface. Using a UAS like the Puma removes the risk to human safety, requires batteries and not fuel, and has been shown to have little-to-no influence on the behavior of wildlife. In fact, NOAA has already used Pumas to great effect during marine mammal and sea bird surveys.

This last point is especially important when you consider an animal like the Pacific walrus. With recent, dramatic summer losses in sea ice, Pacific walruses have been seen congregating en masse on the shoreline of Alaska, a behavior happening earlier and earlier in the year. Disturbance of these large groups of walruses, which could be caused by noisy surveying techniques, creates panic in the animals, causing a stampede that could end up trampling and killing young walruses.

Pumas Fly but Jaguars Swim

While the Pumas were busy scanning the ice and sea from the sky, scientists from Woods Hole Oceanographic Institute were fast at work deploying their “Jaguar” beneath the water. The Jaguar is an Autonomous Underwater Vehicle (AUV) designed to map the Arctic sea floor, but during Arctic Shield 2013, the science team instead used it to map the curves and channels on the underside of the sea ice.

For example, if an oil spill occurred near an ice floe, responders would need to know where oil could pool up or be funneled in the curves or channels beneath the sea ice. The Jaguar uses acoustic technology to map the differences in sea ice thickness or “draft” as it travels along its programmed path under the ice. A suite of oceanographic sensors are also installed that measure water temperature, conductivity, pressure, and salinity along the way. In addition, scientists can install an optical back-scatter sensor that can detect oil in the water column.

To top things off, the Jaguar’s footprint is relatively low. The entire system is easily shipped, only requires a three-person team to operate, and doesn’t need a large vessel like the Healy to be deployed. Having a highly functional, low-impact tool is a major advantage out on the Arctic Ocean.

A Mapping Tool Made for the Arctic

It was with remote environments like the Arctic in mind that the Office of Response and Restoration developed Stand-alone ERMA, an internet-independent version of our Arctic ERMA online mapping tool used in response efforts for oil spills, hazardous waste spills, and ship groundings. My role in Arctic Shield was to integrate and display the data collected by the technologies I just described into Stand-alone ERMA. ERMA integrates multiple data sources and displays them in a single interactive map. With the resulting data-rich map, I could demonstrate the advantage of establishing a common operational picture during an oil spill response scenario—all without an internet connection.

During Arctic Shield 2013, Stand-alone ERMA was integrated into the ship’s local network, and as new data were recorded and displayed, everyone on the ship, from the bridge to the science decks, could view the same results on their computer screens.

In a typical oil spill response, you can have decision makers from federal, state, and local governments; private industry; and a multitude of scientists and technicians all working together. Everyone needs access to the same information, especially when it is constantly changing, in order to make the most informed decisions. But if internet availability is sporadic or nonexistent (not unusual in the Alaskan Arctic), most common operational pictures are rendered inoperable. Stand-alone ERMA bridges that gap, while providing the same experience and tools found with the online version. Demonstrating the utility of Stand-alone ERMA aboard the Healy made the advantages of a flexible common operational picture very clear.

Mind the Gaps (and Bridge Them)

The purpose of these demonstrations during Arctic Shield 2013 was to identify technologies that could improve oil spill response capabilities in the Arctic environment. Not all of the technologies being demonstrated were recently developed or even developed specifically for oil spill response. The Coast Guard Research and Development Center, which organized the demonstration, has taken a critical look at the difficulties and challenges associated with operating in an icy ocean environment. As a result they have identified a wide variety of technologies—some of which we demonstrated on this trip—that could potentially improve response during an actual oil spill. Still, a great deal of work remains as we work to better understand Arctic ecosystems and overcome the challenges of stewardship in a new and uncertain period in our history.

Looking over the bow of the Healy as the ship fractured the ice beneath, I caught a brief glimpse of polar bear tracks in the snow. The animal itself was nowhere to be seen, but as I watched the tracks fade into the distance, I was reminded of why I was there. When you’re out on the ice, breathing in the frigid air, knowing that polar bears are out there hunting and raising cubs, you realize what is right in front of you is the only place like it in the world. Being a part of Arctic Shield 2013 was an incredibly rewarding and humbling experience, one that is helping me figure out what data we still need and develop the tools to strengthen our ability to respond to an oil spill.

Breaking Ice: A Personal Journey amid Preparations for Arctic Oil Spills

Editor’s Note: September is National Preparedness Month. It is a time to prepare yourself and those in your care for emergencies and disasters of all kinds. The following story follows one way NOAA’s Office of Response and Restoration is preparing for a potential oil spill emergency in the Arctic. To learn more about how you can be prepared for other types of emergencies, visit http://www.ready.gov.

This is the second in a series of posts about Arctic Shield 2013 by the Office of Response and Restoration’s Zach Winters-Staszak. Read his first post, “Arctic-bound.”

Fog and snow obscure the tundra below as the plane descends. The seat belt sign goes off and a man reaches for his bag in the overhead bin, the quote on the back of his shirt spelling out just how far I now am from Seattle: “Vegetarian. An ancient tribal slang for the village idiot who can’t hunt, fish or ride.” I’ve returned to Barrow, Alaska, top of the world for now, but I have higher latitudes in my future.

On previous trips to Barrow, the village was blanketed by snow, chilled by negative air temperatures, and surrounded by coastal sea ice. As I step out from the baggage claim, the air is balmy and the landscape is thawed, leaving only mud and gravel for me to drag the now-useless wheels of my luggage and heavy equipment case across. When I arrive at the hotel lobby, I hear familiar voices from conference calls over the last few months as we prepared for this logistically complex undertaking, and I quickly begin to put faces to names and voices.

Top of the World

In a previous blog post, I gave a brief overview of my involvement in the oil spill training exercise Arctic Shield 2013. I was joining scientists, analysts, the United States Coast Guard (USCG), and the crew aboard the USCG Cutter Healy to demonstrate the capabilities of oil spill response technologies in the remote and challenging environment of the Arctic Ocean.

But before I dive into those details, I first wanted to share my behind-the-scenes story of life aboard this Coast Guard icebreaker—because this was no ordinary “office” for our work. We would travel north up and over the broken sheets of Arctic sea ice before turning south through the Bering Sea, east to the Gulf of Alaska and finally dock in Seward, Alaska.

Even though I’ve been here before, Barrow still retains an uncompromising allure. Bowhead whale bones, baleen, umiaqs (seal-skin hulled canoes used for spring whaling), and caribou pelts can be seen at every turn, affirming the traditional ways synonymous with Arctic communities—as well as what’s at stake if a major oil spill occurred here.

Each time I come to Barrow, I make it a point to visit the Iñupiat Heritage Center. Local subsistence hunters and community elders can be found there, continuing to create the traditional tools and artwork they have for centuries. As I listen to stories of generations of hardship and perseverance on the ice, I’m quickly reminded of what’s at stake and why it’s imperative to be ready to protect the natural resources they rely on.

Cultural tourism has become a major draw to Barrow but is perhaps overshadowed by the destination itself. From a geographical and strategic standpoint, Barrow is a major checkpoint for international travel by sea.

During my time in the village, there was a German cruise boat traveling through from the Northwest Passage and Greenland that anchored just offshore and was busy unloading European tourists by Zodiac. This alone highlights the importance of field demonstrations like Arctic Shield. Transportation activities for tourism and commerce are increasing in the region, escalating the risk of oil spills and accidents. Ironically, the Healy is anchored just offshore as well, giving our team a spectacular view into our next couple weeks.

Working Aboard an Icebreaker

When you’re on a ship, you have no choice but to eat whatever the galley serves up, three times a day. The Coast Guard puts Sriracha hot sauce on everything: eggs (makes sense), grilled cheese (OK), the hardly identifiable steamed broccoli (understandable), and chicken marsala (not so sure). As I get to know both the crew and the science team after one such meal, questions about the Healy itself come up. The galley chief quickly proclaims, “Have you seen the engine room? We call it PFM or Pure Freaking Magic. The Healy generates more power than the whole village of Barrow.” To put that in perspective, Barrow is the largest village on Alaska’s North Slope, with a population over 4,100 people.

Essentially, the ship itself is a floating village. The Healy has amenities to support over 100 people, makes ample (and screaming hot) fresh water on site, and houses multiple scientific laboratories with a combined area of 4,200 ft².  Designed to operate in temperatures down to -50°F, the Healy can break 4.5-foot-thick ice continuously and has the capacity of backing and ramming 8-foot-thick ice. Indeed, watching chunks of ice the size of minivans come rolling up from under the bow of the ship is impressive.

The sound of breaking ice from below deck is at first nerve-racking, but eventually it actually begins to lull you to sleep at night. Then, just as soon as the landscape of fragmented sea ice and frigid temperatures becomes familiar, it vanishes. The morning after completing the response technology demonstrations, I wake up and the ship has turned south. We have escaped the ice floe and are once again surrounded by open ocean. Walruses and whales swim by, understandably in a hurry considering a 420-foot red island is steaming in their direction at 14 knots.

As we pass through the Bering Strait, Russia comes into view. And as we travel through Unimak Pass, the Aleutian Islands, and on to Seward, I take in the unforgettable landscapes that I hope our preparations during Arctic Shield will help protect.

Stay tuned for my next post, when I’ll give an in-depth look at the critical response technologies we demonstrated on the Healy, some humbling insights for me to consider as an oil spill responder, and an update on whether my personal goal to see a polar bear remained elusive.
