New FY 2016 Funding Opportunity Available to Research Ecological Effects of Sea Level Rise

NCCOS has created a funding opportunity for Fiscal Year 2016 for researchers to assess the ability of natural and nature-based coastal features to mitigate the effects of sea level rise and coastal inundation. The geographic scope of this funding is limited to coastal regions of southern California (defined as San Louis Obispo County south to the U.S./Mexico border) and […]

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 […]

NOAA Embarks on Final Expedition to Investigate Coral Ecosystem Connectivity in Gulf of Mexico

Last week, a NOAA-funded investigation of the relatively healthy deep reefs of Pulley Ridge (off the southwest coast of Florida) began its fourth and final expedition. During the two-week mission, the team will launch a remotely operated vehicle from the University of Miami’s R/V F.G. Walton Smith to photograph benthic and fish communities and collect fish […]

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 […]

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 […]
