Item Sediment mixing and dissolved oxygen and nutrient dynamics in a six week microcosm experiment containing Great Lakes macroinvertebrates(2024-05-06) Huff, Audrey H; Rigdon, Matt; Zalusky, John; Katsev, Sergei; Ozersky, Ted; huff0114@umn.edu; Huff, Audrey E; University of Minnesota Duluth Large Lakes ObservatoryPhysical and geochemical dynamics at the sediment-water interface in a six-week microcosm experiment including Great Lakes macroinvertebrates (dreissenids, Diporeia, and oligochaete worms) with varying functional biology. Microcosms included single and multi-taxon treatments and data includes sediment mixing rate (as luminophore profiles), weekly NO2,3 and NH3 fluxes between the sediment and overlying water, weekly sediment dissolved oxygen microprofiles, and pore water NO2,3, NH3, and P profiles.Item Spring and summer 2019 seston, excretion, and tissue C:N:P data for quagga mussels (Dreissena rostriformis bugensis) in Lakes Michigan and Huron(2023-04-05) Huff, Audrey E.; Zalusky, John; Katsev, Sergei; Ozersky, Ted; huff0114@umn.edu; Huff, Audrey E.; University of Minnesota Duluth Large Lakes ObservatoryData include quagga mussel food, tissue, and excretion C, N, and P concentrations from sites throughout Lakes Huron and Michigan (including Green Bay) in the spring and summer of 2019. Samples were taken along trophic status and depth gradients. Site characteristics analyzed include site depth, seston C, N, and P concentrations, chlorophyll a concentration, water temperature, dissolved oxygen concentration, and mussel biomass.
