Transport And Fate Of Phosphorus In The Nearshore Zone Of Lake Michigan, Nathan Van Ee

Theses and Dissertations

Bioavailable phosphorus loads exported to Lake Michigan from the Milwaukee and Sheboygan River Watersheds appear to have increased in the last 40 years despite meeting total phosphorus (TP) loading goals set by the Great Lakes Water Quality Agreement (GLWQA).Overall, bioavailability of P delivered from the Milwaukee and Sheboygan Rivers was highest during the warmer months, which coincides with the nearshore nuisance algae growth season. However, first order loss rates of SRP calculated during baseflow recession were also greatest during the summer, suggesting that increased river residence time during the summer could reduce export of bioavailable P. Observations of phosphorus partitioning …

Monitoring Stormwater Contaminants In The Puget Sound Nearshore: An Active Biomonitoring Tool Using Transplanted Mussels (Mytilus Trossulus), Jennifer Lanksbury, Andrea J. Carey, Mariko M. Langness, Brandi Lubliner, Laurie A. Niewolny, James E. West

Salish Sea Ecosystem Conference

Stormwater delivers a diverse range of contaminants to receiving waters including Puget Sound. Monitoring stormwater pollutants and their effects on biota is critical to informing best management practices aimed at recovering Puget Sound health. In the winter of 2012/13, the Washington Department of Fish and Wildlife’s Toxics-focused Biological Observation System (TBiOS) team conducted a pilot study using transplanted mussels to characterize the extent and magnitude of contamination in nearshore biota of Puget Sound. Mussels are now a key TBiOS indicator organism for tracking contaminants in the nearshore, and the Stormwater Action Monitoring (SAM) program has adopted mussels for nearshore stormwater …

Microplastics Contamination In Blue Mussels (Mytilus Edulis (L.)) And Marine Sediments Along The Coast Of British Columbia, Canada, Megane Neauport, Marie Noel, Anahita Etemadifar, Peter Ross

Salish Sea Ecosystem Conference

Contamination of marine ecosystems with microplastics (plastic particles ≤ 5mm) is now recognized as a serious and growing threat to sealife. One major concern is that invertebrates, fish, seabirds and marine mammals mistake plastic for food, leading to suffocation, blockage of the gut and/or malnutrition. Microplastics have been detected in sediment around the world, highlighting the propensity of this matrix to serve as a sink. Due to their extensive filter-feeding activity, marine bivalves are directly exposed to this structural pollutant. In the present study, we investigate microplastics contamination in nearshore subtidal sediment and mussel samples collected at 43 sites along …

Modeling Lake Michigan Nearshore Carbon And Phosphorus Dynamics, Joseph Henry Fillingham

Theses and Dissertations

Dreissenid mussels, in particular quagga mussels (Dreissena rostiformis bugensis), are transforming the Lake Michigan ecosystem by clearing the water column, recycling phosphorus and modifying benthic habitat. These impacts are thought to have caused observed declines in the spring phytoplankton bloom in Lake Michigan, as well as changes to food web structure and declines in the abundance of critical invertebrate and fish species. In the nearshore zone, the resurgence of benthic Cladophora algae to nuisance levels not observed since phosphorus loading abatement policies instituted in the 1970s has also been attributed to water column clearing and phosphorus recycling by mussels. Using …
