Light Shed on Hawaiian Reef Fish Food Sources and Trophic Positions

NOAA-funded scientists studying the diets of 22 species of Hawaiian coral reef fish living at both shallow (0-30 meters) and mesophotic (30-150 meters) depths found that the food source differed for invertebrate-feeding and omnivorous fishes and remained the same for plankton-feeding fishes. Although the sources of food were different between shallow and mesophotic depths, the […]

Research Links Land Use, Shoreline Hardening, and Species Abundance

Recent NCCOS research provides solid evidence that reduced aquatic species abundance in the Northeast is linked with increased agricultural land use and hardened shorelines. Results from the study are published in the September issue of Estuaries and Coasts and highlighted in Coastal & Estuarine Science News (CESN). The overall research project evaluated 587 sites, 39 sub-estuaries, and 15 […]

Can You Guess What Deep-sea Animal We Saw off the Channel Islands?

This past spring NCCOS scientists and their partners explored and mapped part of the seafloor in the Channel Islands National Marine Sanctuary (see May 30 news post). The data gathered are being used to fill gaps in sanctuary maps, characterize seafloor habitat, and help inform management decisions within and around the sanctuary. The team’s remotely operated […]

NCCOS Hosts Deep-Sea Coral Identification Workshop

In July, the NCCOS Deep Coral Ecology Laboratory (DCEL) held a two-day workshop on the taxonomy and morphological identification of deep-sea corals. The workshop was held in conjunction with the Center for Coastal and Marine Ecosystems (CCME) annual meeting in Charleston, SC, and attended by graduate students from the University of Texas Rio Grande Valley […]

Socioeconomic Infographics for CNMI and USVI Coral Reefs Published

In support of the National Coral Reef Monitoring Plan (NCRMP), NOAA social scientists and their partners collect a variety of socioeconomic data in seven U.S. coral jurisdictions to track information on each jurisdiction’s population, social and economic structure, the impacts of society on coral reefs, and the impacts of coral management on communities. A snapshot […]

Hypoxia Leads to Atlantic Croaker Decline in Gulf of Mexico, Models Show

A team of scientists led by Louisiana State University (LSU) developed a model to understand the impacts of hypoxia (low oxygen) on Atlantic croaker in the northern Gulf of Mexico. Results indicate that chronic large hypoxic zones could result in model estimates of a 25 percent reduction in the long-term population abundance of Atlantic croaker over a […]

NCCOS, Partners Map Unexplored Areas of Western Lake Michigan

Last month a team of scientists from NOAA’s National Centers for Coastal Ocean Science (NCCOS) completed a two-week field mission aboard NOAA Research Vessel Storm to map the lakebed and explore shipwrecks in Lake Michigan. The team collaborated with the Office of National Marine Sanctuaries and the Great Lakes Environmental Research Laboratory to collect swath […]

Study of Freshwater Turtles to Improve Treatment of Toxins in Sea Turtles

New research is paying off long-term for endangered sea turtles facing illness and even death during Florida red tides. From 2011-2014, the NCCOS sponsored project “Brevetoxin Metabolism and Physiology – A Freshwater Model of Morbidity in Endangered Sea Turtles” used non-endangered freshwater turtles as models to determine the effects of Florida red tide on endangered sea […]
