This feature is part of a monthly series profiling scientists and technicians who provide exemplary contributions to the mission of NOAA’s Office of Response and Restoration (OR&R). In our latest "Minds Behind OR&R," meet environmental scientist Laurie Sullivan.

What we do to Help Endangered Species

Posted Fri, 05/15/2020 - 11:00

For over 40 years, the 1973 Endangered Species Act has helped protect native plants and animals and that habitats where they live, and many government agencies play a role in that important work. That’s one reason the United States celebrates Endangered Species Day every year in May.

From March 30 to April 20, tune in as we go back in time to the day of our country’s largest marine oil spill, what’s happened since then, and how we’re better prepared for future spills. In our latest blog, learn more about how the spill impacted sea turtles and marine mammals. 

Assessing the Impacts from Deepwater Horizon

Posted Sat, 04/04/2020 - 16:57

The 2010 Deepwater Horizon disaster spread spilled oil deep into the ocean’s depths and along the shores of the Gulf of Mexico, compromising the complex ecosystem and local economies. The response and the natural resources damage assessment were the largest in the nation’s history. In this 2017 blog, learn more about the natural resources injured by the Deepwater Horizon spill, and how our team assessed those injuries. 

Deepwater Horizon: Response in the Midst of an Historic Crisis

Posted Mon, 03/30/2020 - 12:00

The Deepwater Horizon oil spill began on April 20, 2010, with a blowout of BP’s Macondo drilling platform in the Gulf of Mexico. In addition to the death of 11 men, the spill resulted in the largest mobilization of resources addressing an environmental emergency in the history of the United States. The size of the spill required the Emergency Response Division to refine tracking subsurface oil, flowrate calculations, and long-term oil transport modeling. Data and information management became a paramount issue ...

Three Ways to Assess Marine Mammals During Oil Spills

Since thousands of oil spills of varying sizes occur in U.S. waters each year, oil spill scientists must be prepared to respond to and assess the impacts of oil on marine mammals. To do this, the NOAA has published: "Guidelines for Assessing Exposure and Impacts of Oil Spills on Marine Mammals," which is available for the public on the NOAA Central Library website. These guidelines provide a review of considerations for marine mammals under NOAA's jurisdiction, incorporating knowledge gained from previous oil spills.

Using ESI Maps to Set Priorities in the Chaos of an Oil Spill

This week, we’re taking a closer look at what sensitivity mapping is, how it’s used, and why it’s so important. A snapshot of the resources in a specific area, sensitivity mapping can be a valuable tool both in and out of the spill response community. Our latest blog takes you through the process of using sensitivity mapping to prioritize response activities during an oil spill.

Rivers of the 'Dammed,' Rising from the Grave

*A Halloween Spooky Science Story 

Once there were six waterways cursed by pollution. 

But terrifying toxins and oozing oil spills were not the first dooms to befall these rivers, each of them had already been dammed. The dams had been constructed for a variety of important reasons, but as the years passed and they fell out of use, an evil crept over them. 

Keystone Species Arctic Cod Extremely Sensitive to Oil Exposure

By Dr. Sarah Allan, Office of Response and Restoration

Arctic cod (Boreogadus saida) are small, ice-affiliated forage fish, that can make up more than 80% of all living fish in Arctic waters. Arctic cod have a circumpolar distribution that includes the Chukchi, Beaufort, and Bering seas in the Alaskan Arctic, and are a critical link in Arctic food webs. 

This keystone Arctic species is also particularly vulnerable to oil spills, which was the focus of a new study titled “Embryonic crude oil exposure impairs growth and lipid allocation in a keystone Arctic forage fish.”

Hollings Scholar Wraps Up Summer at NOAA with Story Map on ‘Building a Resilient Community’
