We are part of a collaborative multi-agency effort that is developing high-resolution benthic habitat maps in key areas of the Great Lakes. Our maps inform decisions to address a range ...

Climate Change and Acidification Impacts on Cyanob...

The Great Lakes experience recurrent toxin-producing cyanobacterial harmful algal blooms (cHABs). While cHAB events have been well-studied in recent years, little attention has been given to acidification in the Great ...

Enhancing Third-generation Environmental Sample Pr...

Monitoring the increase in cyanobacterial harmful algal blooms (HABs) in nearshore environments is challenging. Recent development of a long-range autonomous underwater vehicle (AUV) equipped with a third-generation Environmental Sample Processor ...

Although phosphorus typically limits the growth of freshwater phytoplankton populations, little is known about how the common toxic alga Microcystis aeruginosa responds to variations in phosphorus concentrations and sources. Our ...

Forecasting the Causes, Consequences, and Potentia...

In recent years, the central basin of Lake Erie has experienced low-oxygen conditions, despite measures taken by surrounding states and provinces to reduce nutrient inputs. We studied the factors that ...

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 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 ...

NOAA Predicts Moderate to Larger than Moderate Har...

Predicted bloom severity for 2024 as compared to previous years. Blooms with a severity index above 5 generally pose greater risk to drinking water and recreation in Lake Erie, but ...

2023 Lake Erie Algal Bloom More Severe than Predic...

Bloom severity index (SI) for 2002-2023. The SI is based on the amount of biomass over the peak 30-days. The 2023 bloom had a severity of 5.3. A severity below ...

Different Varieties of Microcystins Have Differing...

Research technicians from Dr. Chaffin's laboratory collect Lake Erie water samples for analysis as part of the NCCOS funded study. Models predicting the amount of Microcystis, an alga that forms ...

Smaller Harmful Algal Bloom Predicted for Western ...

Bloom severity index for 2002–2022, and the forecast for 2023. The bloom severity index is based on the amount of biomass over the peak 30-days. NOAA and its research partners ...

NOAA Predicts a Moderate Harmful Algal Bloom for L...

Caption: 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 ...

Smaller Harmful Algal Bloom Predicted for Western ...

Bloom severity index for 2002–2021, and the forecast for 2022. The index is based on the amount of biomass over the peak 30-days. NOAA and its research partners are forecasting ...

Data & Publications

Aquatic invasive species transport via trailered boats: what is being moved, who is moving it, and what can be done?

Trailered boats have been implicated in the spread of aquatic invasive species. There has been, however, little empirical research on the type and quantity of aquatic invasive species being transported, nor on the efficacy of management interventions (e.g., inspection crews, ...

Cruise report : assessment of ecological condition and stressor impacts within Great Lakes region areas of concern (AOCs) : Ashtabula River and Milwaukee estuary

This cruise report is a summary of a field survey conducted within two Great Lakes Region Areas of Concern (AOCs), Ashtabula River and Milwaukee Estuary, August 18 – 25, 2012. Synoptic sampling of multiple ecological indicators was conducted in the ...

Cruise Report: Spring 2006 Survey of Ecological Conditions of the U.S. Middle Atlantic Bight, NOAA Ship Nancy Foster NF-06-06-NCCOS

This cruise report is a summary of a field survey conducted in coastal-ocean waters of the Mid-Atlantic Bight from Nags Head, North Carolina to Cape Cod, Massachusetts and from approximately 1 nautical mile (nm) of shore seaward to the shelf ...

Cruise report: Spring 2007 survey of ecological conditions along the continental shelf off Florida from Anclote Key to West Palm Beach, NOAA ship Nancy Foster Cruise NF-07-08-NCCOS (May 15 - May 28, 2007)

This cruise report is a summary of a field survey conducted in coastal-ocean waters off Florida from Anclote Key to West Palm Beach and from approximately 1 nautical mile (nm) offshore seaward to the shelf break (100 m). The survey ...

Environmental toxicology data collected by the National Status and Trends Program for monitoring contaminants in coastal United States marine water bodies from 01 Jan 1960 to 05 May 2010 (NODC Accession 0074376)

The National Status and Trends Program is comprised of three nationwide programs: Benthic Surveillance, Mussel Watch, and Bioeffects. These programs are in place to observe estuarine and coastal waters nationwide to describe the current status and detect changes in the ...

Eurasian watermilfoil fitness loss and invasion potential following desiccation during simulated overland transport

Vegetative reproduction promotes human-mediated dispersal of aquatic invasive plants as fragments “hitchhike” between water bodies on boats and trailers. However, desiccation of plant fragments may also reduce fitness, decreasing the likelihood of fragment survival as transport distances increase. Current inter-lake ...

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 ...

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 ...

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 ...
