PARTICULATE NUTRIENTS IN THE GREAT LAKES: ANALYZING A 20-YEAR DATASET
The U.S. Environmental Protection Agency Great Lakes National Program Office (GLNPO) has collected water samples for particulate nutrient analysis from all of the Great Lakes since 1997. Samples are collected during GLNPO’s annual spring and summer surveys across the Great Lakes basin. This annual monitoring has resulted in a long-term dataset of particulate phosphorus, particulate nitrogen, particulate carbon, and total suspended solids. In this study, we assess temporal trends of particulate nutrients, compare trends among lakes, and determine how nutrient stoichiometry is changing over time in the Great Lakes. The results will be compared to other long-term datasets, including chlorophyll-a, to investigate changes associated with primary productivity trends across the lakes.
