NOAA Environmental Cooperative Science Center Student Researches Blue Carbon

A graduate student at University of Texas-Rio Grande Valley, Leticia Contreras, recently completed a month-long stay at NOAA’s Center for Coastal Fisheries and Habitat Research in Beaufort, NC.  Contreras worked with NCCOS scientist Carolyn Currin and NRC post-doc Nathan McTigue to test several hypotheses about factors influencing the rate of mangrove leaf decomposition, the subject of […]

NCCOS Sponsors 20 New Research Projects

NCCOS awarded nearly $4.5 million in new research grants while maintaining sponsorship of 42 continuing projects during 2015 for a total of $8.2 million in funding for innovative research. All of the endeavors address significant and complex coastal issues. The projects were selected using a rigorous, competitive, and peer-review process. The cutting-edge research will provide critical […]

New Technology Documents Rapid Phytoplankton Response to Tropical Storms and Hurricanes

A scientific study funded by NCCOS’ ECOHAB program, shows phytoplankton community structure changing rapidly, often by the hour, as tropical cyclones pass by. A revolutionary sampling instrument, the Imaging FlowCytobot (IFCB) allows hourly real-time continuous observation of phytoplankton changes. Over time the IFCB provides an extraordinary view of phytoplankton community structure. Prior studies of phytoplankton responses to […]

NCCOS Community Well-being Data Now Available

In August, an NCCOS collection of community well-being data for the Gulf of Mexico went live on NOAA’s Gulf Data Atlas. The Gulf of Mexico Coastal Community Well-being Data incorporates a variety of publicly available social, economic, and environmental quantitative data collected by federal, state, and local agencies. Data is available for the coastal states […]

Origin of Toxic Red Tides in Texas Identified

New modelling research sponsored by NCCOS shows that Texas red tides originate in the southwestern Gulf of Mexico in the Bay of Campeche. These harmful algal blooms, caused by the dinoflagellate alga Karenia brevis, result in large fish kills, human respiratory irritation, and shellfishing closures in affected areas. Unlike red tides on the west coast […]

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 […]

Hypoxia Leads to Pathological, but Reversible, Changes in Fish Brains

The NCCOS sponsored project, Modeling Reproductive and Population Impacts of Hypoxia in the Northern Gulf of Mexico, led by the University of Texas at Austin, is investigating the impacts of low levels of dissolved oxygen on the brain functions of the Atlantic croaker, a common estuarine and coastal fish inhabiting the east coast of the United States. […]

New Indicator for Gulf of Mexico Toxic Alga Shows Promise

NCCOS-sponsored scientists have discovered a simple indicator to predict one type of harmful algal species bloom or outbreak. The first potentially reliable biological indicator for forecasting a harmful algal bloom of the toxic dinoflagellate species Dinophysis ovum in the Gulf of Mexico is the presence of a primary food source, a small ciliate protozoan. The […]
