Tenacity of Brown Tides Linked to Genetic Flexibility

The genetic flexibility of Aureococcus anophagefferens, the harmful alga responsible for “brown tides” off Long Island, allows it to thrive in conditions other algae cannot tolerate. NCCOS-sponsored scientists assessed this alga’s response to environmental stressors, such as low nutrients and low light, by looking at pieces of its RNA, which tell Aureococcus which proteins to […]

Algal Toxins Pose Health Risk to Dogs

Harmful algal bloom (HAB) toxins, including microcystins, pose health threats and even death for dogs and other pets exposed to the contaminated water, explains a new educational brochure from the New York Sea Grant Program. The brochure, a product of a National Centers for Coastal Ocean Science sponsored research project in the Great Lakes, describes freshwater HABs and their […]

Invasive Asian Carp Could Establish in Lake Erie with Little Effect to Native Fishery

A recent study found that if Asian carp establishes in Lake Erie, the native fisheries might not be significantly affected. Based on consultations with Great Lakes and fisheries specialists, the researchers estimated that Asian carp biomass could range from nearly zero to an even larger presence than the current walleye and yellow perch in Lake Erie. From […]

Coastal Ocean Acidification: The Other Eutrophication Problem

Eutrophication, or increased nutrient loading to estuaries, causes algae to bloom and consequently coastal hypoxia (low oxygen waters) when the algal biomass decomposes. Often overlooked, eutrophication can also produce carbon dioxide, which leads to a lowering of seawater pH (or increasing acidity). A recent invited paper by scientists supported by NCCOS and the NOAA Ocean Acidification Program shows low […]

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 […]
