Forecasting the Spread and Bioeconomic Impacts of ...

We are developing predictions of the arrival and economic impact of non-native aquatic invasive species to better respond to current invasions and prevent future invasions. We are combining scientific, economic, ...

Great Lakes Mussel Watch Program: An Assessment an...

NOAA's Mussel Watch Program has monitored the nation’s coastal waters for chemical contaminants since 1986. These monitoring efforts now include contaminants of emerging concern, such as per- and polyfluoroalkyl substances ...

Great Lakes Mussel Watch Sites Land-use Characteri...

Land use is an important parameter in the assessment of coastal waters, as land-based activities and land-based pollution affect the quality of downstream environments. Land uses and land-use change around ...

Great Lakes Mussel Watch Supports the President’s ...

The President’s Great Lakes Restoration Initiative began in 2010 and provided the financial support for the Great Lakes Mussel Watch, one of several projects of contaminant monitoring with Great Lakes ...

Harmful Algal Bloom (HAB) Forecasting

Our offshore HAB forecasts notify coastal managers before blooms reach the coast. Our forecasts identify harmful blooms, location, size and trajectory. Our early warnings provide health officials, managers and water ...

Hypoxia in Green Bay, Wisconsin: Biogeochemical Dy...

Hypoxia conditions have plagued the lower part of Lake Michigan’s Green Bay and the Fox River for decades. We know nutrients are contributing to the problem, and we are developing ...

Lakebed Mapping and Assessing Ecological Resources...

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, ...

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 ...

Managing the Impacts of Multiple Stressors in Lake...

Along with several partner agencies and institutions, we are funding NOAA’s Great Lakes Environmental Research Laboratory to improve the health of Saginaw Bay and to restore the ecosystem services that ...

NOAA Predicts a Smaller than Average Algal Bloom f...

Blooms with a severity index above 5 generally pose greater risk to drinking water and recreation in Lake Erie, but the impact of a bloom also depends on its location, ...

Scientists Use Land Use, Demographics Data to Mode...

The NOAA National Status and Trends Program (NST) monitors and characterizes the nation’s coastal waters at risk of contamination by anthropogenic inputs. NCCOS social scientists further characterize and model relationships ...

2021 Lake Erie Algal Bloom More Severe than Predic...

Peak Microcystis cyanobacteria bloom biomass in western Lake Erie (Aug 30-Sep 08, 2021). The images used data derived from the Copernicus Sentinel-3 mission provided by EUMETSAT. Blue indicates low concentrations ...

Lake Erie Eutrophication Exacerbated by Release of...

Lake Erie not only experiences eutrophication caused by runoff-laden phosphorus (P), but also by internal P loading caused by recycling of “legacy” P stored in bottom sediments. This phenomenon was ...

First Real-time Toxicity Assessment of Lake Erie A...

NOAA Ecological Forecast Helps Solve Mystery in La...

Residents of several northeast Ohio Lake Erie towns were surprised by a strong, foul smell during the first days of September. The residents, fearing a dangerous gas leak, called their ...

Single-day Intensive Sampling Quantifies Algal Tox...

NCCOS-sponsored researchers and their partners conducted one-day intensive water sampling events in 2018 and 2019 to create high spatial resolution snapshots of the amount and locations of cyanobacterial toxins across ...

NCCOS Expands Monitoring of More Lakes, Coastal Ba...

With harmful algal blooms (HABs) occurring in the nation’s lakes, bays and sounds, NCCOS is expanding HAB monitoring and forecasting to these smaller water bodies which can be resolved by ...

Smaller Harmful Algal Bloom Predicted for Western ...

A boat cuts through an algal bloom in Saginaw Bay, as seen by aircraft during a flyover in summer of 2019. This airborne campaign is ongoing in conjunction with NOAA ...

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 ...

Data & Publications

Evidence of persistent, recurring summertime hypoxia in Green Bay

Six years (2009–2015) of temperature and dissolved oxygen profile data show hypoxic conditions are common in the bottom waters of southern Green Bay, Lake Michigan during the summer. Depleted oxygen concentrations (<5 mg L−1) affect nearly 70% of the 38 ...

Great Lakes Mussel Watch sites land-use characterization and assessment

This report characterizes the land-use around the Mussel Watch Program (MWP) monitoring sites in the Great Lakes. Land-use is an important parameter in the assessment of the nearshore environment, as contaminant monitoring sites are influenced by point and non-point source ...

Great Lakes Mussel Watch: Assessment of Contaminants of Emerging Concern

The current report summarizes Great Lakes mussel tissue contaminants of emerging concern (CEC) data obtained between 2013-2015. The study design informs MWP management, stakeholders and general public about the frequency of occurrence, and the magnitude of CECs in mussels. We ...

Green Bay, Lake Michigan: A proving ground for Great Lakes restoration

Green Bay has sometimes been referred to as the largest freshwater “estuary” in the world. Its watershed, much of it in intensive agriculture, comprises one-third of the Lake Michigan basin and delivers one-third of the lake's total phosphorus load. At ...

Harmful Algal Bloom Forecasting Branch Ocean Color Satellite Imagery Processing Guidelines

The Harmful Algal Bloom - Forecasting Branch (HAB-FB) is a research group within the National Oceanic and Atmospheric Administration (NOAA), National Centers for Coastal Ocean Science (NCCOS) tasked with forecasting and monitoring HABs. One of the more effective ways to ...

In situ, high-resolution time series of dissolved phosphate in Green Bay, Lake Michigan

In nearly every instance in which the environment has been sampled on a higher resolution in time or space, fundamental processes have come to light that were previously undetected or unobserved. In this study, an autonomous dissolved phosphate sensor was ...

Limitations of gravity models in predicting the spread of Eurasian watermilfoil

The effects of non-native invasive species are costly and environmentally damaging, and resources to slow their spread and reduce their effects are scarce. Models that accurately predict where new invasions will occur could guide the efficient allocation of resources to ...

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 ...

Long-term monitoring of ecological conditions in Gray's Reef National Marine Sanctuary: Comparison of soft-bottom benthic assemblages and contaminant levels in sediments and biota in spring 2000 and 2005

As part of an ongoing program of benthic sampling and related assessments of sediment quality at Gray's Reef National Marine Sanctuary (GRNMS) off the coast of Georgia, a survey of soft-bottom benthic habitats was conducted in spring 2005 to characterize ...

National Centers for Coastal Ocean Science (NCCOS) long-term monitoring: Regional Ecological Assessments and National Benthic Inventory (NCEI Accession 0202842)

The NCCOS Regional Ecological Assessments (REA) and NOAA National Benthic Inventory (NBI) include observations of water quality, sediment quality, fish and shellfish tissue chemical contaminants, and benthic infaunal abundance obtained from studies conducted since 1991 by NOAA and partnering institutions ...
