State and Federal Agencies Meet to Improve HAB Surveillance

NOAA and the Centers for Disease Control (CDC) recently co-sponsored a workshop on harmful algal blooms (HABs) to discuss future monitoring of HAB-related illnesses and outbreaks and to discuss with state representatives how NOAA’s remote sensing capabilities can support HAB surveillance. Attendees provided updates on HAB activities in each state and discussed the CDC’s National […]

NOAA Helps Plan National Study on Nutrient Trends in Nation’s Waters

NCCOS’s Dr. Rob Magnien recently represented NOAA at a planning session of the National Academy of Sciences Water Science and Technology Board. The purpose of the meeting was to plan and explore the scientific dimensions and challenges of monitoring and detecting changes in nutrient levels in the nation’s surface and ground water. Over the past […]

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 […]

Guam Students Learn About Coastal Resilience and Conservation

Over a decade ago, fishermen in the village of Umatac (Humåtak) off the southwest coast of Guam found they were not catching the same size and quality of fish. Researchers identified one of the primary reasons to be an accelerated rate of erosion caused by the introduction of feral ungulates (pigs, goats, and deer) and […]

Marine Shellfish Get a ‘One-Two Punch’ from Acidification and Low Oxygen

Recent research has shown that ocean acidification and low oxygen interact to harm early life stages of bay scallops (Argopecten irradians) and hard clams (Mercenaria mercenaria). The study, conducted by Stony Brook University and sponsored by NCCOS and NOAA’s Ocean Acidification Program, found that the combined effects of low pH (high acidity) and low oxygen […]

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 […]

Ocean Sciences Meeting Highlights Results of Sponsored Research

The 2014 Ocean Sciences Meeting showcased the reach and extent of research sponsored by NCCOS, including coral reefs, harmful algal blooms, hypoxia, applying research to management solutions, and integrated ecosystem assessments. NCCOS staff and sponsored research scientists gave over 25 oral and poster presentations and co-chaired a special session on mapping, monitoring, and managing mesophotic […]

South Florida Field Radiometry to Support Cyanobacteria Bloom Detection in Lake Okeechobee

NCCOS staff recently trained several employees of the South Florida Water Management District on the collection of field radiometry for cyanobacteria algorithm development. Radiometry is the measurement of optical radiant energy. As a result of nutrient inputs to Lake Okeechobee, blooms of Anabaena, Microcystis, and other cyanobacteria commonly occur, discoloring the water, producing noxious odors, and making […]
