Spring Flood Outlook Has Implications for Gulf of Mexico and Chesapeake Bay Hypoxia

The NOAA 2014 U.S. Spring Flood Risk Assessment provides an important first look at some of the factors that influence summer hypoxia (low dissolved oxygen) in the Gulf of Mexico and the Chesapeake Bay. This year’s predicted elevated flood risk in the Upper Midwest and the Ohio River Valley may result in a larger hypoxic […]

Chesapeake Bay Dead Zones Show Marine Worm Species Shifts

A recent NCCOS-sponsored study conducted by the University of Maryland’s Center for Environmental Science has found a hypoxia-induced shift in marine worm communities in Chesapeake Bay to ones made up of species that are extremely adaptable to stressful conditions like hypoxia (low dissolved oxygen). The team also found that the magnitude of the marine worm […]

Environmental Conditions Can Influence Development of Dermo Disease in Oysters

A recent NCCOS-sponsored study by the Smithsonian Institution showed that long-term exposure to daily fluctuations of hypoxia (low dissolved oxygen) increased Dermo disease (Perkinsus marinus) infection in previously uninfected eastern oysters. Surprisingly, daily-cycling pH (a measure of acidity) did not affect Dermo disease infection levels in conjunction with daily-cycling hypoxia or with continuous normal oxygen […]

Surface Elevation Trends Help Us Prepare for Climate Change

Predicting future patterns of coastal inundation from sea level rise requires knowledge of changes in sea level and changes in elevation of land surface. Surface elevation tables—mechanical devices permanently installed in wetlands—allow scientists to measure small changes in surface elevation precisely and accurately. These devices have been installed in coastal wetlands across the U.S. by […]

Working to Reduce Toxic Blue-Green Algal Blooms in Chesapeake Bay

NCCOS-sponsored researchers recently explored several promising techniques to mitigate toxic cyanobacteria (blue-green algae) blooms in the Chesapeake Bay region. The team focused on sediment-flocculation, in which local sediments and commercial clays are combined with the flocculating compound chitosan to sink and bury Microcystis cyanobacteria blooms. Other techniques evaluated included post-bloom flushing and early spring deployment of […]

NOAA Administrator Honors NCCOS Employees

At the 2013 NOAA Administrator and Technology Transfer Awards ceremony, Acting NOAA Administrator Dr. Kathryn Sullivan recognized four NCCOS employees for accomplishments that brought unusual credit to NOAA and the Department of Commerce. The following NCCOS employees received the Administrator’s Award: Kimberly Puglise, Felix Martinez, and Michael Dowgiallo for “leading foundational research and consensus building […]

NCCOS Marine Biologist Brings Sea Creatures and Scuba Gear to Kindergarteners

On May 9th NCCOS’s Dr. Matt Kendall engaged 16 kindergartners at Seneca Academy in Darnestown, MD by demonstrating his scuba gear and talking about what it was like working underwater. Dr. Kendall showed short videos of squid locomotion, squids changing color and shooting ink to protect themselves. The children then dissected real squid and studied major […]
