Nutrient Stress and Source Identification in the C...
Observed blooms of algae including caulerpa and valonia in the coral reef ecosystems of Ofu and Olosega are of concern to coastal managers. It has been hypothesized that excess nutrients ...
Pollution and Biological Health Assessment of Fjor...
State managers must assess contamination at abandoned mines, sewage outfalls, harbors, and other sites. We are determining the physical and chemical properties of sediments; measuring the chemical contaminants in sediment, ...
Risk Assessment of Mosquito-control Agents
We are identifying the toxic effects that mosquito-control agents may have on estuarine species and the coastal environment. The information we gather is being placed in a database of mosquito-control ...
Science to Support a Climate-Ready Dungeness Crab ...
The productive coastal ocean off northern California, Oregon, and Washington is facing impacts from multiple environmental stressors, including hypoxia, harmful algal blooms, increasing water temperatures, and ocean acidification. This work ...
Shallow Water Hypoxia: Tipping the Balance for Ind...
We are investigating the impacts of extreme daily fluctuations in oxygen and pH on fish and invertebrates in the Chesapeake Bay. The modeling tools we produce will improve the ability ...
Technical Support for Inception of Florida DEP Cor...
Eutrophication is the over-abundance of nutrients in a body of water that results in harmful algal blooms, fish kills, and in some cases ecosystem collapse. In coral reef ecosystems, excess ...
The Columbia River Plume and Harmful Algal Blooms ...
We identified the oceanographic causes and transport routes for the harmful alga Pseudo-nitzschia in the offshore waters of the Pacific Northwest and improved predictability of the arrival of harmful algal ...
The Impact of Temperature and Salinity on Pesticid...
We tested the toxicity of pesticides to shrimp and phytoplankton to better understand the environmental risks of these chemicals. We found that pesticide toxicity can change with temperature and salinity ...

A recent report released by the National Centers for Coastal Ocean Science (NCCOS)found relationships between land use, water quality, and several important aquatic organisms in certain tributaries of the Chesapeake ...
Study Assesses Ecological Conditions in Gray's Ree...
A new report from NOAA's National Centers for Coastal Ocean Science (NCCOS) describes ecological conditions and stressors in sediments and biota in Gray's Reef National Marine Sanctuary (GRNMS), located off ...
Scientists Expect Slightly Below Average Chesapeak...
Low river flow and nutrient loading reason for smaller predicted size Scientists are expecting that this year's Chesapeake Bay hypoxic low-oxygen zone, also called the "dead zone," will be approximately ...
New Research Shows Both Blooms and Toxicity of Har...
A cyanobacterial bloom in a freshwater lake. Credit C. Gobler, SUNY Stony Brook. In freshwaters around the world blooms of cyanobacteria (commonly known as blue-green algae) are considered a serious ...
NCCOS-sponsored Research Paper Receives Annual Awa...
An NCCOS-sponsored project publication was selected for the 2012 "Chandler-Misener Award" by the Journal of Great Lakes Research. Titled ' Historical pattern of phosphorus loading to Lake Erie watersheds,' the ...
Algae's hunger ramps up red tide toxins | HeraldTr...
The mysterious red tide toxin that has killed a record number of manatees and brought countless dead fish to Southwest Florida beaches over the past few months could finally have ...
