Multi-agency Team Investigates Chemical Pollution in Niagara River

A multi-agency team of researchers has begun a summer-long project to investigate chemical pollution in the Niagara River. The team will collect water, sediment, and mussel samples from various locations along a 25-mile stretch of the river and seven of its tributaries, all above Niagara Falls. Data from this sampling are expected to be available […]

Webinar Highlights Citizen Science to Kick-off EPA’s 2014 HAB Awareness Campaign

NCCOS’s Steve Morton and staff from the New York Department of Environmental Conservation recently led an EPA webinar on harmful algal blooms (HABs) that explored volunteer monitoring opportunities open to the public. Four hundred and twenty participants from academia, industry, and government learned more about NOAA’s Phytoplankton Monitoring Network, which uses volunteers to monitor for […]

Lecture Informs Public of Long Island’s Coastal Ills, Solutions

NCCOS-funded researcher Dr. Christopher Gobler and his students recently reported on the nearly complete collapse of hard clam fisheries in Great South Bay and bay scallop fisheries off the East End of Long Island due to annually occurring harmful algal blooms, hypoxia, and acidification. The team discovered excess nitrogen entering groundwater from septic tanks and […]

Some Coastal Fish May be Able to Adapt to an Acidifying Environment

A new study shows that some coastal fish may be able to condition their offspring to tolerate seasonally acidifying environments, a result never shown before in wild fish populations. Researchers funded by NCCOS and NOAA’s Ocean Acidification Program sampled a wild, spawning population of Atlantic silversides, then combined this information with carbon dioxide exposure experiments […]

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 […]

New Report Addresses Re-eutrophication and Hypoxia in Lake Erie

A new report aimed at Great Lakes policymakers calls for Lake Erie total phosphorus reductions almost 50 percent greater than previous recommendations. Recent total phosphorus reduction recommendations may not reduce hypoxia (low dissolved oxygen) as called for by the Great Lakes Water Quality Agreement undertaken by Canada and the United States. Reducing total phosphorus loading […]

Ocean Acidification Promotes Disruptive and Harmful Algal Blooms on Our Coasts

The general decline in ocean pH (i.e., more acidic conditions) from the increasing concentrations of carbon dioxide (CO2) is well documented. Also well documented are increased nutrients entering coastal waters often promoting excessive and ecosystem disruptive algae blooms, including harmful algal blooms. The decay of these coastal blooms promotes bacterial respiration resulting in increased CO2, […]

NCCOS Sponsors Harmful Algal Bloom Workshops for Upstate New York

New York’s borders encompass fresh, estuarine, and salt waters, each plagued by harmful algal bloom (HAB) outbreaks that pose risks to human health and the economic vitality of coastal communities. NCCOS is informing the upstate New York public and management community of the predicted rise of freshwater CyanoHABs by sponsoring workshops that provide information on a […]
