Ecological Prediction, Aquatic
Invasive Species, Physical Environmental
Prediction, and Environmental Observing

2012 Lake Huron Coordinated Science and Monitoring Initiative During the 2012 field season, GLERL scientists and numerous partners will conduct an intensive research effort in Lake Huron. The EPA and NOAA sponsored field campaign, entitled “2012 Lake Huron Coordinated Science and Monitoring Initiative,” will help scientists understand the structure and function of the Lake Huron ecosystem - from bacteria to fish - and clarify the impacts of stressors such as invasive species, climate change, nutrient loading, and overfishing. The intensive Lake Huron field campaign in 2012 will serve as the foundation for a long-term ecological research program, similar to the program that the laboratory has carried out in southern Lake Michigan since 1980. |

Multiple Stressors in Saginaw Bay In conjunction with several partner agencies and institutions, GLERL is conducting a study of the effects of multiple stressors on Saginaw Bay in Lake Huron. Saginaw Bay has been subjected to numerous stressors originating from human activities, including: toxic contaminants, excess nutrients, sediments, overfishing, exotic species, and declining water levels. The combined effect of these problems has compromised the health of Saginaw Bay and resulted in the loss of many ecosystem features and services that people value. The goal of this project is to help identify management actions that will improve water quality and fish production in the Bay and restore the ecosystem services that are important to the surrounding area. |

Great Lakes Aquatic Nonindigenous Species Information System (GLANSIS) The Great Lakes have a long history of aquatic nonindigenous species (ANS) introductions – both intentional and unintentional. As of 2007, over 180 nonindigenous species have been reported to have reproducing populations in the Great Lakes basin and their connecting channels and water bodies. The number of species documented in GLANSIS must be interpreted as a minimum. |

Great Lakes Coastal Forecasting System (GLCFS) The Great Lakes Coastal Forecasting System (GLCFS) is a system of computerized models that can simulate and predict the three-dimensional structure of currents, temperatures, water level fluctuations, wind waves, ice, and sediments in the Great Lakes. It provides timely and relevant information on physical processes to the many people whose lives, jobs, and property are impacted by the Great Lakes. Nowcasts and forecasts are generated continuously. Developed by GLERL and the Ohio State University and supported by the National Weather Service, operational implementation of this utility is accomplished by NOAA’s Coast Survey Development Laboratory and Center for Operational Oceanographic Products and Services (see sidebar, GLOFS). These predictions provide timely information to lake carriers, mariners, port managers, emergency response teams and recreational boaters. |

Harmful Algal Blooms and Human Health Recent increases in cyanobacterial HABs in the Great Lakes has caused significant concern for human and ecosystem health due to the production of toxins by bloom species. In the Great Lakes, Microcystis dominates the cyanobacterial bloom community and produces the hepatotoxin microcystin. Studies have documented the presence of microcystins in the Great Lakes, at times exceeding the recommended limit of 1 µg L-1 of microcystin established by the World Health Organization for drinking water supplies. GLERL research, in conjunction with the Center of Excellence for Great Lakes and Human Health, will directly address whether algal toxins could impact human health in the communities of the Lake Erie Islands and have broader implications for other communities using the Great Lakes as a drinking water source. |

Real-time Environmental Coastal Observations
Network (RECON) Project This project brings together a team of NOAA and Great Lakes institutes to construct experimental, integrated environmental observing systems. The integrated environmental observatory provide real-time observations of chemical, biological, and physical parameters. |
 |
Real-time Meteorological
Observation Network GLERL established and maintains a GLERL established and maintains a network of real-time meteorological stations at exposed coastal sites around southern Lake Michigan (Chicago, Milwaukee, Kenosha, South Haven and Michigan City). This data is used by boaters and fishermen and also provides input for wave and circulation models. |
