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 […]

Technology Transfer Between NOAA and France Improve Caribbean Ciguatoxin Detection

A PhD candidate from the French Research Institute for Exploitation of the Sea (IFREMER), Francesco Pisapia, is visiting the NCCOS Center for Coastal Fisheries and Habitat Research (CCFHR) for eleven weeks of intensive training on the method and technique of cytotoxicity assays to detect ciguatoxins (CTXs) and maitotoxins (MTXs) in fish tissue and cell cultures. […]

Oceanic Continental Margin Dead Zones Emerge as Threats to Coastal Waters

Declines in oxygen levels of coastal waters have accelerated in recent decades creating “dead zones” not only in more publicized nearshore areas but in open ocean offshore regions of the continental shelves and slopes. Once treated as separate phenomena and distinct fields of study, scientists now see offshore and coastal hypoxia as interconnected, resulting in […]

NCCOS Works to Track and Eliminate Freshwater Algal Toxins

A new study has documented the fate of microcystins—the most common of the freshwater blue-green algae toxins—and the challenges for monitoring them. The study is part of a larger NCCOS-sponsored project whose goal is to identify bacteria capable of degrading microcystins and to develop an affordable and efficient water filtration system to house such microorganisms. Microcystins inhibit and […]

U.S. Department of Transportation Updates Coastal Infrastructure Risk Assessment Using NCCOS Research

Modeling concepts developed by the NCCOS sponsored Gulf of Mexico Ecological Effects of Sea Level Rise (EESLR) project are being used by the U. S. Department of Transportation (DOT) as a case study in the latest DOT hydraulic engineering manual. The manual, “Highways in the Coastal Environment: Assessing Extreme Events,” provides technical guidance and methods […]

How Climate Change Could Impact Harmful Algal Blooms

Harmful algal blooms (HABs) are projected to increase as sea surface temperatures rise and ocean acidification continues according to Dr. Alan Lewitus, of NOAA’s National Centers for Coastal Ocean Science. His findings were shared during a symposium at George Mason University in October which covered such topics as climate change and extreme weather effects on […]

NCCOS Improves Paralytic Shellfish Poisoning Toxin Testing for FDA

Scientists from the National Centers for Coastal Ocean Science (NCCOS) provided training in Charleston, South Carolina, August 26-28, 2014 on the NCCOS-developed receptor binding assay for paralytic shellfish poisoning toxins to visiting scientists from the US Food and Drug Administration’s (FDA) Northeast Regional Laboratory, which plans to implement the assay for regulatory testing of shellfish imports. Paralytic shellfish […]
