NCCOS Supports Algal Toxin Testing in El Salvador

The Marine Toxin Laboratory at the University of El Salvador (LABTOX-UES), supported by the International Atomic Energy Agency (IAEA) is undergoing the national accreditation process for the analysis of saxitoxin, a marine toxin generated by some harmful algae blooms that builds up in shellfish. Consumption of contaminated shellfish can cause paralytic shellfish poisoning (PSP). The […]

Metals in Dwarf Sperm Whales Provide Information on Ocean Health

A recent study found the presence of heavy metals in the kidney and liver tissues of dwarf sperm whales (Kogia sima) stranded along South Carolina’s coast. As long-lived high trophic level predators, dwarf sperm whales are exposed to environmental contaminants from anthropogenic sources and may serve as an indicator of offshore marine pollution. Between 1990 […]

Workshop Develops Linkages between NOS and Environmental Cooperative Science Center Universities

Last week, the NCCOS Charleston laboratories hosted a workshop to develop linkages between the National Ocean Service (NOS) and NOAA’s Environmental Cooperative Science Center (ECSC) that will increase science capacity for both entities and create student training opportunities. The goal of the ECSC is to train a new generation of environmental scientists, particularly from under-represented minority groups, and […]

NCCOS Improves Coastal Resilience of South Carolina

In order to improve coastal resilience, scientists used the SWARM modeling system to investigate runoff in certain watersheds in South Carolina (SC). Research results from this collaborative project to prioritize and model runoff volume sensitivities of tidal headwaters were presented to the Beaufort County Watershed Advisory Committee (WAC) on September 10, 2015. This modeling work […]

NCCOS Scientists Attend ‘Climate Adaptation for Coastal Communities’ Course

This summer, a small group of NCCOS scientists completed an interactive training course intended to provide participants with the necessary skills to address climate adaptation planning within their local community. The course, developed by NOAA’s Office for Coastal Management and local partners, included discussions on climate change trends and impacts, how to scope and conduct […]

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 […]

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 […]
