Land Based Sources of Pollution in Faga’alu Bay, T...
Land based sources of pollution (LBSP) have the potential to adversely impact coral reef ecosystem, either by directly affecting coral health and reproduction, or by altering the surrounding ecosystem in ...
Land Use and Ecosystem Health: Decision-making Too...
We are studying how land-use decisions affect the health of an area’s ecosystem. We are building models that show the consequences of land-use choices on the Chesapeake Bay health and ...
Land-based Pollution Impacts on Ecosystem Services...
Environmental conditions in the coastal zone are in decline due to increased coastal development and pollution. Using land-use modeling and environmental observations, we are determining the specific links between coastal ...
LEOFS-Hypoxia: Operational Lake Erie Hypoxia Forec...
Deep waters of Lake Erie’s central basin have areas of low dissolved oxygen. Weather conditions can determine if this low oxygen (hypoxic) water will be taken up by treatment plants, ...
Life and Death of Karenia brevis Blooms in the Eas...
An extensive bloom of the brevetoxin-producing Karenia brevis occurred from 2017 to 2019 in Florida. The economic, environmental, and human health impacts were quite severe during this event. This regional ...
Life and Death of a Karenia Bloom in the Western G...
Harmful algal blooms (HABs) are increasing in frequency and pose a threat to human and environmental health. Blooms of Karenia brevis occur nearly annually along the Florida coast which has ...
Linking Biogeochemistry to Harmful Algal Bloom Nut...
The Long Island Brown Tide (LIBT) threatens shellfish and sea grasses in mid-Atlantic estuaries. LIBT-specific gene expression assays are being developed and tested for enzymes and transporters that allow LIBT ...
Linking Coral Reefs, Coastal Watersheds, and Human...
Our research project combines ecological studies, physical oceanographic research, and social science to reduce human impacts (e.g., runoff, sediment, and non-point source pollution) that threaten the coastal coral reefs of ...
Linking Models and Field Experiments to Forecast A...
We are investigating the links between environmental variables and harmful algal bloom (HAB) toxins in Lake Erie to better understand the process of toxin development and to forecast HAB toxicity ...
Lionfish Control in the National Marine Sanctuarie...
The invasive lionfish is one of the most dominant top predators of reef communities in the temperate and tropical Atlantic Ocean. Lionfish are reducing native reef fish and marine invertebrate ...

Special Satellite Algorithm Used to Detect Irish H...
NCCOS collaboration with a major Irish public research university and the Irish agency responsible for marine research led to the successful adaptation of a NCCOS employed satellite ocean color processing ...
NOAA Forecasts Average ‘Dead Zone’ for Gulf of Mex...
NCCOS scientists are forecasting this summer’s Gulf of Mexico hypoxic zone or “dead zone”—an area of low to no oxygen that can kill fish and other marine life— to be ...
Potential Effects of Bigheaded Carps on Four Great...
A NCCOS study, co-sponsored with the Great Lakes Restoration Initiative, used an ecosystem model to evaluate the potential risk of two species of highly invasive bigheaded carp fish (a type ...

Research Paper Deemed One of Special Significance ...
A research paper, supported in part by NCCOS, measuring the metabolic cost to a red tide dinoflagellate to defend itself against predation (consumption) has been recommended by the prestigious Faculty ...
New Program Created to Test Harmful Algal Bloom Co...
A new research program funded by the U.S. Army Corps of Engineers will determine the efficacy of nanobubble ozone technology (NBOT) to control cyanobacteria and their toxins in Ohio's Grand ...
NOAA Lake Erie Harmful Algal Bloom Early Season Pr...
Western Lake Erie is expected to experience a lower than average harmful algal bloom (HAB) this summer, according to the first 2021 Lake Erie Harmful Algal Bloom Early Season Projection ...
Low, Gulf-Wide Bloom Predicted for Gulf of Maine R...
Researchers with NOAA’s National Centers for Coastal Ocean Science (NCCOS) are expecting a low, gulf-wide red tide for the Gulf of Maine this spring and summer, continuing the pattern of ...
Ecosystem Approach to Everglades Water Flow Needed...
A new study partially funded by the NCCOS Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) Program describes the various stressors that have impacted South Florida ecosystems over the last ...
External Review of NCCOS Chemical Contaminants Pro...
Last fall, a six-member panel of experts reviewed NCCOS's Fate and Effects of Chemical Contaminants (F&ECC) Program, and concluded that the program provides national leadership; conducts high-quality research, and works ...

Linking environmental conditions and ship movements to estimate invasive species transport across the global shipping network
Some nations, and the International Maritime Organization, are moving towards requirements for managing ballast water to reduce the number of alien species transported and released. These and other measures will be most efficient when targeted at ships posing the greatest ...
Linking molecular microbial ecology to geochemistry in a coastal hypoxic zone
Multiple environmental mechanisms have been proposed to control bottom water hypoxia (<2 mg O2 L?1) in the northern Gulf of Mexico Louisiana shelf. Near-bottom hypoxia has been attributed to a direct consumption of oxygen through benthic microbial respiration and a ...
Long-term decline in the calanoid copepod Acartia tonsa in central Chesapeake Bay, USA: An indirect effect of eutrophication
A long-term abundance record of the calanoid copepod Acartia tonsa in the Maryland portion of Chesapeake Bay was compiled from 1966 to 2002. A significant downward trend in the summertime abundance of Acartia tonsa was found in central Chesapeake Bay ...
Long-term trends in Chesapeake Bay seasonal hypoxia, stratification, and nutrient loading
A previously observed shift in the relationship between Chesapeake Bay hypoxia and nitrogen loading has pressing implications on the efficacy of nutrient management. Detailed temporal analyses of long-term hypoxia, nitrogen loads, and stratification were conducted to reveal different within-summer trends ...
Louisiana Hypoxia Survey 2009: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2009 (NODC Accession 0099531)
CTD data were taken during the 2009 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, secchi depth, and station information data ...
Louisiana Hypoxia Surveys 1998 - 2002: Physical, biological, and chemical data collected off the coast of Louisiana as part of a long-term study of hypoxia (NODC Accession 0002033)
