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.

*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. 

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.”

Working under NOAA’s Office of Response and Restoration, 2019 Hollings scholar Leah Moore spent her summer working on the story map “Building a Resilient Community: NOAA’s Hazard Exposure and Risk Exploration (HERE) Tool” — a publicly available link will be available later this summer.

During National Water Quality Month, NOAA’s Office of Response and Restoration shares some of the ways we preserve and improve water quality through cleanup and restoration. 

NOAA’s Office of Response and Restoration develops scientific solutions to keep the coasts clean from threats of oil, hazardous waste, and marine debris — all of which are major pollutants that can hugely affect the water quality of our coastal natural resources. 

This blog was written by Kavya Varkey, a high school student from the Seattle area who interned with OR&R in the summer of 2018. Kavya was instrumental in developing the new story map on the Lower Duwamish River Superfund site. An urban river with a history of industrial pollution that began in the 1900s, the Lower Duwamish River continues to undergo both cleanup and restoration efforts.

Few animals capture the human imagination like sea turtles. Sea turtles are living fossils, they have glided through the Earth’s oceans for over 110 million years. But today, sea turtles face new, human-caused threats that put all seven species at risk of extinction. One of these threats is oil spills.

During National Safe Boating Week (May 18-24), NOAA’s Office of Response and Restoration is taking a closer look at the anatomy of abandoned and derelict vessels.

An abandoned or derelict vessel (ADV) can be a pollution risk, and depending on the size of the vessel, could result in a pretty massive spill of oil, chemicals, or other hazardous materials. But even without a spill, the vessel itself can damage the environment.
