NOAA Hollings Scholars Research Oil Spill Dispersants

NOAA Hollings Scholars Charlotte Eckmann (University of South Carolina) and Pamela Betancourt (Florida State University) spent their summer at the NCCOS laboratory in Charleston, South Carolina researching the effects of oil spill dispersants on estuarine shrimp. Eckmann compared dispersant toxicity under different salinities, while Betancourt investigated dispersant effects on shrimp development. Their findings will be used […]

Hardened Shorelines Make it Hard for Submerged Aquatic Vegetation

A recent NCCOS-funded study found that shoreline hardening, particularly riprap, has a negative effect on the abundance of submerged aquatic vegetation (SAV). Riprap, which is made up of rocks and boulders piled along the shoreline, is commonly used to prevent shoreline erosion, but once installed, alters the natural processes and composition of the land–sea interface. The […]

SONAR Data Supports Policy Decision Making in Near Real-Time

NCCOS scientists aboard the NOAA ship Nancy Foster provided near real-time mapping data to the South Atlantic Fishery Management Council as they considered designating a new special management zone to protect spawning deep-water snapper and grouper.  The mapping data provided to the Council, less than 24 hours after the request came in, allowed the Council […]

Gulf of Mexico Dead Zone Larger than Predicted After Heavy June Rains

Scientists supported by NOAA NCCOS, EPA and the Gulf of Mexico Research Initiative have mapped the size of the 2015 Gulf of Mexico low-oxygen dead zone. The areal extent of hypoxia measures approximately 6,474 square miles, about the size of Connecticut and Massachusetts combined, exceeding the prediction from June. Nutrient run off from agricultural and other human […]

NCCOS Prepares Toxin Sensor for Deployment in Puget Sound, WA

NCCOS scientist, Tina Mikulski, completed critical calibration of the domoic acid (DA) toxin sensor on an Environmental Sample Processor (ESP) platform located at NOAA’s Northwest Fisheries Science Center (NWFSC) in Seattle, Washington. This ESP (referred to as ‘ESPfriday’) will be deployed for the first time in Puget Sound beginning in early August and will generate autonomous, […]

NCCOS Studies Effects of Dispersants and Weathered Oil

To study the impacts of dispersed oil on estuarine organisms and ecosystems, NCCOS scientists used tidal estuarine simulation units (called mesocosms) to mimic the conditions in an estuary affected by weathered crude oil. In the mesocosms, artificially weathered crude oil, with and without dispersants, was applied during three consecutive high tide events. The exposure phase lasted […]

NCCOS Hypoxia Forecasts Prove Accurate

For over ten years NCCOS has developed and improved hypoxia (dead zone) forecasts similar to seasonal weather forecasts. The accuracy of these forecasts is proving to be quite good. Professor Don Scavia of the University of Michigan tracks the accuracy of the NCCOS-funded annual forecasts and finds the models work well in years without hurricanes or […]
