On September 5, 2016, a marsh excavator operated by Great Lakes Dredge and Dock Company tracked over pipeline while performing restoration activities in Bay Long, a sub-estuary of Barataria Bay, discharging approximately 5,300 gallons of crude oil into the Gulf of Mexico. The pipeline was shut in and is no longer leaking. The incident occurred at an active restoration site for the Deepwater Horizon oil spill. The cause of the incident is still under investigation.

NOAA’s Office of Response and Restoration has been providing scientific support including trajectories and fate of oil, resources at risk, information on tides and currents, and technical guidance towards the response. Other roles provided by NOAA are guidance on Shoreline Cleanup and Assessment Technique (SCAT), a systematic method for surveying an affected shoreline after an oil spill, as well as data management and updates through Environmental Response Management Application (ERMA®). OR&R’s Emergency Response Division has a team of six on site.

Abandoned Vessels of Florida’s Forgotten Coast

This is a post by NOAA Scientific Support Coordinator Adam Davis of the Office of Response and Restoration.

Along Florida’s Forgotten Coast, a pair of osprey had built a nest on an abandoned vessel. The U.S. Coast Guard called in NOAA for assistance as they were trying to remove fuel from that boat with minimal impact to wildlife. (NOAA)

There is a stretch of the Florida Panhandle east of the more heavily developed beach destinations of Destin and Panama City that some refer to as the “Forgotten Coast.” This area has vast tracts of pine forest including large stands of longleaf pine and savanna, towering dunes and nearly undeveloped barrier islands, seemingly endless coastal marsh, and miles and miles of winding shoreline along its expansive bays and coastal rivers.

It is no coincidence that much of the area is undeveloped; reserves, wildlife refuges, and other federal and state protected lands and waters occupy a large percentage of the area.

However, this flattened landscape of wild greens and blues is occasionally punctuated by the unnatural texture of human influence of a certain type: rusting hulls, broken masts, boats half-submerged in the muddy waters. It was one of these abandoned and decaying vessels that brought me to Florida’s Forgotten Coast.

Birds-Eye View of a Problem

The U.S. Coast Guard as well as state and local agencies and organizations have been working to address potential pollution threats from a number of abandoned and derelict boats sprinkled throughout this region. Vessels like these often still have oils and other hazardous materials on board, which can leak into the surrounding waters, posing a threat to public and environmental health and safety.

As a Scientific Support Coordinator for NOAA’s Office of Response and Restoration, I provide assistance to the Coast Guard in their pollution response efforts. This support often involves analyzing which natural resources are vulnerable to pollution and the potential fate and effects of oil or chemicals released into the environment.

In this case, the Coast Guard called me with an unusual complication in their efforts: A pair of osprey had taken up residence on one of these abandoned vessels. Their nest of sticks was perched atop the ship’s mast, now bent at a precarious 45 degree angle. The Coast Guard needed to know what kind of impacts might result from assessing the vessel’s pollution potential and what might be involved in potentially moving the osprey nest, or the vessel, if needed.

As a federal agency, the Coast Guard must adhere to federal statutes that protect wildlife, such as the Endangered Species Act and the Migratory Bird Treaty Act. Essentially, these statutes require the Coast Guard (or other person or organization) to consider what effect their actions might have on protected species, in this case, osprey.

This is where we Scientific Support Coordinators often can provide some assistance.  A large part of our support in this area involves coordinating with the “trustee” agencies responsible for the stewardship of the relevant natural resources.

My challenge is evaluating the scientific and technical aspects of the planned action (disturbing the chicks and their parents or possibly moving the osprey nest in order to remove the vessel), weighing possible effects of those actions against threats posed by no action, and communicating all of that in an intelligible way to trustees, stakeholders, and the agency undertaking the action in question.

Fortunately, the pollution assessment and removal in the case of the osprey-inhabited vessel proved very straightforward and the abandoned vessels project got off to a good start.

Abandoned But Not Forgotten

NOAA’s Adam Davis helped the U.S. Coast Guard with a project spanning more than 230 miles of Florida coastline and resulted in the removal of hundreds of gallons of fuel and other hazardous materials from six abandoned vessels and one shoreline facility. (NOAA)

Over the course of eight weeks, I was fortunate to contribute in a number of ways to this project. For example, I joined several aerial overflights of the coast from Panama City to St. Marks, Florida, and participated in numerous boat rides throughout the Apalachicola Bay watershed to identify, assess, and craft strategies for pollution removal from abandoned vessels.

Ultimately, the project spanned more than 230 miles of coastline and resulted in the removal of hundreds of gallons of fuel and other hazardous materials from six abandoned vessels and one shoreline facility. Most of the fuel was removed from vessels located in highly sensitive and valuable habitats, such as those located along the Jackson and Brother’s Rivers.

Portions of both of these rivers are located within the Apalachicola National Estuarine Research Reserve and are designated as critical habitat for Gulf sturgeon, a federally threatened species of fish that, like salmon, migrates between rivers and the ocean.

Even a small release of marine fuel in areas like this can have significant negative environmental consequences. Impacts can be even more severe if they occur during a time when species are most vulnerable, such as when actively spawning, breeding, or nesting.  In addition, spills in these otherwise pristine, protected areas can have negative consequences for important commercial and recreational activities that rely upon the health of the ecosystem as a whole.

When NOAA supports the Coast Guard with abandoned vessels work, our efforts often involve analyzing which natural resources are vulnerable to pollution and the potential fate and effects of oil or chemicals released into the environment. These Coast Guard boats are equipped to remove fuel from abandoned vessels. (NOAA)

While we’d like to be able to remove the entire vessels every time, which can be navigation hazards and create marine debris, funding options are often limited for abandoned vessels. However, the Oil Pollution Act of 1990 enables us to remove the hazardous materials on board and reduce that environmental threat.

I find working in the field directly alongside my Coast Guard colleagues to be invaluable. Inevitably, I come away from these experiences having learned a bit more and increased my appreciation for the uniqueness of both the people and the place. Hopefully, that makes me even better prepared to work with them in the future—and in the beautiful and remote wilds of the Forgotten Coast.

Preparing for Anything: What to Do When a Hypothetical Ferry Disaster Overlaps with a National Presidential Convention

This is a post by NOAA Scientific Support Coordinator Frank Csulak.

In June 2016, team of federal and state emergency responders practiced responding to a hypothetical ferry disaster and oil spill scenario in anticipation of the Democratic National Convention, which occurred in Philadelphia at the end of July. (Credit: Kevin Harber, CC BY-NC-ND 2.0)

When you’re in the business of emergency response, you need to be prepared for all kinds of disasters and all kinds of scenarios. Being a NOAA Scientific Support Coordinator, the disaster scenarios I’m usually involved with have some connection to the coast or major U.S. waterways.

And being ready for a disaster means practicing pretty much exactly what you would do during an emergency response, even if it’s for a relatively unlikely scenario, such as a catastrophic ferry explosion, collision, and oil spill during a major political party convention.

What follows is the hypothetical scenario that a team of federal and state emergency responders walked through at a training workshop from June 12-14, 2016 in Philadelphia, Pennsylvania.

U.S Coast Guard Sector Delaware Bay hosted this practice scenario in anticipation of the Democratic National Convention, which occurred (thankfully without any major security incidents) in Philadelphia at the end of July. The team involved was comprised of members from the U.S. Secret Service, Federal Bureau of Investigation, New Jersey and Pennsylvania state police, U.S. Coast Guard, and NOAA.

Ready for Anything You Can Imagine (And This Is Imagined)

Exercise scenario: It is the first day of the Democratic National Convention, which is taking place in Philadelphia, Pennsylvania. Tens of thousands of people, including hundreds of elected officials and the Democratic Party’s presumptive presidential candidate, are just arriving at the event.

The Secret Service reports that VIPs continue to land at Philadelphia International Airport. Security is tight. A large safety perimeter has been established around the convention center, with surrounding streets and highways closed to all traffic and thousands of law enforcement officers posted at strategic locations throughout the city.

Meanwhile, the RiverLink Ferry is making the 2:00 p.m. trip from Philadelphia to Camden, New Jersey. There are 21 passengers and two crew members on board. The ferry is crossing the federal channel of the Delaware River when an explosion of unknown cause erupts from the ferry’s engine room. The explosion causes the vessel to lose propulsion and steering. It begins listing to the starboard side and drifting down the Delaware River. Smoke can be seen billowing from vents and openings.

Simultaneously, the tug The Caribbean Sea II is pushing the barge The Resource II upriver. The barge attempted to avoid the distressed ferry but is unsuccessful, striking the ferry and causing significant structural damage to both vessels.

Numerous ferry passengers are thrown onto the deck or into the river; others begin jumping into the water. Responders from the U.S. Coast Guard, New Jersey State Police Marine Services Bureau, and the marine units of the Philadelphia Fire and Police Departments all rushed to the scene. Already, they encounter both seriously injured survivors and casualties as far as 200 yards down river of the vessels.

Rescue boats pick up eight survivors from the water and begin offloading them at Penn’s Landing Marina. Responders continue to evacuate people from the sinking ferry until it slips completely under water in the vicinity of the Penn’s Landing helicopter port. A total of 14 people are rescued and three bodies recovered, some found as far as a quarter mile down river. Six people remain missing.

Thankfully, no injuries are reported among the tugboat’s four person crew. However, one of the two crewmembers on the barge, a 60-year-old male, has fallen and broken his arm. He appears to be going into shock and needs to be evacuated.

As a result of the collision, the tug only has partial steering capabilities but continues to push the barge several hundred yards up river, where it drops anchor. The two damaged vessels remain in the river channel, and as responders assess the vessels’ conditions, they uncover that the barge is leaking oil. Manhole-sized bubbles of oil are burping to the water’s surface, coming from the port side damage below the water line. Oil appears to be leaking from a tank which is holding 5,000 barrels of oil. In all, the barge is carrying 50,000 barrels of heavy bunker fuel oil.

Reining in Hypothetical Chaos

Three damaged vessels. People injured, dead, and missing. A potentially large oil spill on a busy river. First responders diverted from a high-security national event to a local aquatic incident In other words, quite a hypothetical mess.

Was the explosion on the ferry due to terrorism? Was it due to human error? Or was it due to a mechanical malfunction in the engine room? We had to imagine how we would deal with these many complicated issues in the heat of the moment.

As a member of the local Coast Guard’s response team during this exercise, I helped with many key decisions and procedures and with establishing priorities for response. I acted as a member of what’s known in the emergency response community as the “Unified Command,” or the established hierarchy of agencies and organizations responding to an emergency, such as an oil spill or hurricane.

In this scenario, I was specifically charged with commanding, coordinating, and managing the oil spill response, which is my specialty. I started by identifying and obtaining resources to support the spill response and cleanup and conducting an assessment of natural resources at risk from the oil. Meanwhile, I coordinated with my NOAA support team of scientists back in Seattle, Washington, to provide information on local weather conditions, tides, oil trajectory forecasts, and modeling of the oil’s fate and effects.

In addition, I had to coordinate a variety of notifications and consultations required under the Endangered Species Act, the Essential Fish Habitat provision of the Magnuson-Stevens Act, and the National Historic Preservation Act, which protects historical and archaeological sites.

As you can see, my role during a disaster like this hypothetical one is far-reaching. And that’s not even everything. I also helped protect nearby wetlands and other environmentally sensitive areas from the thick, spreading oil; prioritized which areas needed protective booming to prevent contact with oil; and led the response’s environmental team, which had representatives from the U.S. Fish and Wildlife Service, Delaware, Pennsylvania, New Jersey, and the U.S. Coast Guard. Of course, all of this was an exercise and there was no ferry incident and no oil spill.

During the actual Democratic National Convention, which took place July 25–29, 2016, I was ready and waiting for any call for help from Coast Guard Sector Delaware Bay. I’m pleased to report that it never came, but if it did, I’d know what to do.

Editor’s note: NOAA’s Office of Response and Restoration also supported the U.S. Coast Guard’s maritime security activities surrounding the Republican National Convention in Cleveland, Ohio, July 18–21, 2016. Two NOAA staff members worked as part of the Coast Guard’s Incident Management Team in Cleveland, managing the event’s data in our online mapping tool known as ERMA® (Environmental Response Management Application), and coordinating with the several other agencies involved with the convention’s security.

The Coast Guard provided maritime security and monitored potential situations along the Lake Erie shoreline and the Cuyahoga River during the convention. ERMA allowed Coast Guard leadership and others in the command post to access near real-time data, such as locations of field teams and tracked vessels, as well as other agency data such as Department of Homeland Security safety zones, infrastructure status, and protest locations. This gave them a comprehensive picture of the Coast Guard’s efforts and the ability to assess potential issues from any location.

Improving Currents Predictions for Washington Waters Will Help Efforts to Prevent and Respond to Oil Spills

This is a post by Amy MacFadyen, NOAA oceanographer and modeler in the Office of Response and Restoration’s Emergency Response Division.

As a sea kayaking enthusiast who enjoys paddling the waters of Washington’s Puget Sound, I need to have up-to-date information about the currents I’m passing through. Accurate predictions of the strong tidal currents in the sound are critical to safe navigation, and kayak trips in particular need to be timed carefully to ensure safe passage of certain regions.

As a NOAA oceanographer and modeler, I also depend on accurate information about ocean currents to predict where spilled pollutants may travel in the marine environment.

Sound Information

These are two reasons I was excited to learn that NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) is performing a scientific survey of currents in the marine waters of the Puget Sound, the San Juan Islands, and the Strait of Juan de Fuca. They began in the south sound in the summer of 2015, deploying almost 50 devices known as Acoustic Doppler Current Profilers to measure ocean currents at various depths throughout the water column.

Work is getting underway this summer to continue gathering data. The observations collected during this survey will enable NOAA to provide improved tidal current predictions to commercial and recreational mariners. But these updated predictions will also help my line of work with oil spill response.

When oil spills occur at sea, NOAA’s Office of Response and Restoration provides scientific support to the Coast Guard, including predictions of the movement and fate of the oil. Accurate predictions of the oil trajectory may help responders protect sensitive shorelines and direct cleanup operations.

Spills Closer to Home

In the last few years, I’ve modeled oil movement for numerous spills and traveled on scene to assist in the oil spill response.

Seeing oil on the water and shorelines of places ranging from Santa Barbara, California, to Matagorda Island, Texas, I can’t help but think about both the possibility of a spill closer to my home in Puget Sound and our ability to model the movement of the oil there.

When oil spills in the marine environment, it spreads quickly, forming thin slicks on the ocean surface that are transported by winds and currents.

Puget Sound is a glacially carved fjord system of interconnected marine waterways and deep basins separated by shallower regions called sills.

Tidal currents in these narrow, silled connection channels can reach fairly swift speeds of up to 5-6 mph, whereas in the deep basins the currents are much slower (typically less than 1-2 mph).

Accurate predictions of currents within the sound will be critical to forecasting oil movement. Today’s predictions for this region rely on limited amounts of data gathered from the 1930s-1960s. Thanks to both these current surveys and modern technological advances, we can expect significant progress in the accuracy of these predictions.

The information collected on the NOAA current surveys will also be used to support the creation of an Operational Forecast System for Puget Sound, a numerical model which will provide short-term forecasts of water level, currents, water temperature, and salinity—information that is critical to oil spill trajectory forecasting.

Making Safer Moves

With the methods for transporting oil through Washington rapidly shifting and the number of vessels carrying oil increasing, the risks for oil spills are changing as well. Here, a fuel barge passes through Puget Sound. (NOAA)

More accurate current and water level predictions are good for oil spill modeling, but they are even better for oil spill prevention by making navigating through our waterways safer.

Until fairly recently, 90% of the oil moving through Washington (mainly to and from refineries) traveled by ship. But by 2014, that number dropped to less than 60%, with rail and pipelines making up the difference.

Because the methods for transporting oil through Washington are shifting, the risks for oil spills shift as well. However, even with the recent increase in crude oil being delivered by train, the number of vessels transporting oil through state waters has gone up as well, increasing the risk of a large oil spill in Puget Sound.

With such a dynamic oil transportation system and last December’s repeal of a decades-long ban on exporting U.S. crude oil, the Washington Department of Ecology has decided to update its vessel traffic risk assessment for the Puget Sound. Results from the risk assessment will ultimately be used to inform spill prevention measures and help us become even better prepared to respond to a spill.

The takeaway? Both state and federal agencies are working to make Washington waters safer.

NOAA Supporting Spill Response in the Green Canyon Oil Reserve Area of the Gulf of Mexico

Vessels skim oil from the surface of the Gulf of Mexico.

Vessels conduct skimming operations, May 14, 2016, in response to an estimated 88,200 gallons of crude oil discharged from a segment of flow line at the Glider Field approximately 90 miles south of Timbalier Island, Louisiana. As of May 15, the vessels have removed a combined total of more than 51,000 gallons of oily-water mixture since the discharge on May 12, 2016. (U.S. Coast Guard)

NOAA’s Office of Response and Restoration is supporting the U.S. Coast Guard response to an oil spill in the Green Canyon oil reserve area in the Gulf of Mexico. We are providing oil spill trajectory analysis and information on natural resources potentially at risk from the oil. The NOAA Scientific Support Coordinator has been on-scene.

The spill occurred at approximately 11:00 a.m. on May 12, 2016 when 2,100 barrels (88,200 gallons) of oil was discharged from a Shell subsea well-head flow line at the Glider Field. Since then, the source has been secured and the pipeline is no longer leaking. The U.S. Coast Guard reports that the spill happened approximately 90 miles south of Timbalier Island, Louisiana.

We are providing scientific support, including consulting with natural resource trustees and environmental compliance requirements, identifying natural resources at risk, coordinating overflight reports, modeling the spill’s trajectory, and coordinating spatial data needs, such as displaying response data in a “common operational picture.” The reported oil trajectory is in a westerly direction with no expected shoreline impact at this time.

How Does NOAA Model Oil Spills?

Dark oil drifts near the populated shores of Berkeley and Emerville, California.

After the cargo ship M/V Cosco Busan struck the San Francisco-Oakland Bay Bridge in 2007, NOAA oceanographers modeled how wind, waves, tides, and weather would carry the ship’s fuel oil across San Francisco Bay. Here, dark oil drifts near the shores of Berkeley and Emerville, California, on November 9, 2007. (NOAA)

One foggy morning in 2007, a cargo ship was gliding across the gray waters of San Francisco Bay when it ran into trouble, quite literally. This ship, the M/V Cosco Busan, struck the Bay Bridge, tearing a hundred-foot-long gash in its hull and releasing 53,000 gallons of thick, sticky fuel oil into the bay.

When such an oil spill, or even the threat of a spill, happens in coastal waters, the U.S. Coast Guard asks the oceanographers at NOAA’s Office of Response and Restoration for an oil spill trajectory.

Watch as NOAA’s Ocean Service breaks down what an oil spill trajectory is in a one-minute video, giving a peek at how we model the oil’s path during a spill.

Using a specialized NOAA computer model, called GNOME, our oceanographers forecast the movement of spilled oil on the water surface. With the help of data for winds, tides, weather, and ocean currents, they model where the oil is most likely to travel and how quickly it may come ashore or threaten vulnerable coastal resources, such as endangered seabirds or a busy shipping lane.

During the Deepwater Horizon oil spill, we produced dozens of oil spill trajectory maps, starting on April 21 and ending August 23, 2010, when aerial surveys and satellite analyses eventually showed no recoverable oil in the spill area. You can download the trajectory maps from that spill.

Learn more about how we model and respond to oil spills:

Attempting to Answer One Question Over and Over Again: Where Will the Oil Go?

“Over the duration of a typical spill, we’ll revise and reissue our forecast maps on a daily basis. These maps include our best prediction of where the oil might go and the regions of highest oil coverage, as well as what is known as a “confidence boundary.” This is a line encircling not just our best predictions for oil coverage but also a broader area on the map reflecting the full possible range in our forecasts [PDF].

Our oceanographers include this confidence boundary on the forecast maps to indicate that there is a chance that oil could be located anywhere inside its borders, depending on actual conditions for wind, weather, and currents.”

A Bird’s Eye View: Looking for Oil Spills from the Sky

“Aerial overflights are surveys from airplanes or helicopters which help responders find oil slicks as they move and break up across a potentially wide expanse of water … Overflights give snapshots of where the oil is located and how it is behaving at a specific date and time, which we use to compare to our oceanographic models. By visually confirming an oil slick’s location, we can provide even more accurate forecasts of where the oil is expected to go, which is a key component of response operations.”

Five Key Questions NOAA Scientists Ask During Oil Spills

“Responders can potentially clean up what is on top of the water but recovering oil droplets from the water column is practically impossible. This is why it is so important to spill responders to receive accurate predictions of the movement of the surface slicks so they can quickly implement cleanup or prevention strategies.”

Supporting the Response to a Platform Fire and Oil Spill in Bayou Sorrel, Louisiana

Fire burns in one of several oil tanks on a platform in a bayou.

The Coast Guard, with state and local partners, is responding to an oil production platform fire in Bayou Sorrel, Louisiana, March 15, 2016. One of the tanks reportedly collapsed, releasing an unknown amount of crude oil into a canal. (U.S. Coast Guard)

On the morning of March 15, 2016, the U.S. Coast Guard requested assistance from NOAA‘s Office of Response and Restoration for an oil production platform fire near Berry Lake in Bayou Sorrel, Louisiana.

While crews were working to dismantle the platform, one of the oil storage tanks caught fire. No injuries have been reported. The U.S. Coast Guard is leading the response with state and local agencies.

The platform and one of its storage tanks burned throughout the day on March 15 before the tank partially collapsed, releasing crude oil into a canal. Most of the oil released from the tank continued to burn on the water surface and was consumed.

Responders contained the remaining oil and burn residue in the canal with boom.

A second tank on the platform subsequently caught fire but has been extinguished. The two storage tanks had a maximum capacity of more than 33,000 gallons of crude oil.

We are assisting the Coast Guard’s response by coordinating local weather forecast support, modeling the potential trajectory of spills of oil or burn residue, and outlining the wildlife and habitats that could be at risk in the area. A NOAA Scientific Support Coordinator has reported to the response to provide further help and assess potential impacts of the oil spill.

Bayou Sorrel is predominantly composed of seasonally flooded, forested wetlands with some patches of freshwater marshes and open canals. While oil is unlikely to penetrate flooded or water-saturated soils, it will readily coat and become mixed with floating debris such as branches and leaves.

A variety of birds, particularly diving and wading birds and waterfowl, may be present in the area and might be at risk of coming into contact with oil, which can coat their feathers, be ingested, or inhaled. In addition, fish and invertebrates such as crawfish may be present or spawning in the marshy habitats surrounding the oil platform, and alligators and small-to-medium-sized mammals including mink and river otters may be nearby.

In 2013, NOAA provided on-site technical support for an oil spill from a pipeline in Bayou Sorrel and helped coordinate a controlled burn of the spilled oil in the area’s flooded, wooded swamps. Additionally, we assisted with other oil spills in this area in 2015, 2007, and 1988.

Look for more information about the current oil spill and fire here and at the U.S. Coast Guard’s media site.
