Impact/Purpose:
Lake Huron, similarly to the other Great Lakes, has been sampled extensively as part of several research studies such as the Cooperative Science and Monitoring Initiative (CSMI) and the National Coastal Condition Assessment (NCCA). However, there are no recent (after 2008) comprehensive nutrient loadings estimates for Lake Huron. Other than Saginaw Bay, little has also been done in terms of modeling the lake. Although results from sampling studies provides a good picture of existing nutrient (eutrophication) conditions, results from this study show how current loading estimates and model results can improve our understanding of Lake Huron and provide a seasonal and longer-term picture of conditions in the lake.
Description:
Over the past number of years, Lake Huron has been sampled extensively as part of several research studies such as the Cooperative Science and Monitoring Initiative (CSMI) and the National Coastal Condition Assessment (NCCA). However, with the exception of Lake Erie, there are no recent comprehensive nutrient loadings estimates for the Great lakes including Lake Huron. Other than Saginaw Bay, little has also been done in terms of modeling the lake. Here we will present preliminary results from recent lake sampling studies, and show and discuss why continuous loadings for Lake Huron (and the other Great Lakes) are important to assess the lake. We will also show results from recent Great lakes modeling studies and demonstrate how simple models can be informative by pointing out gaps in existing sampling and research in Lake Huron, and by complementing on-going nutrient sampling studies.
