    A comparison of Satellite Derived Versus In-Situ Chlorophyll Values on Two Manitoba Great Lakes
    (2018-12) Herbert, Claire; McCullough, Greg; Kling, H.J.; Barber, David
    The waters of Lakes Winnipegosis and Manitoba are Case II waters, meaning their optical properties are influenced not only by phytoplankton (chlorophyll-a) but also by total suspended sediments (TSS) and coloured dissolved organic matter (CDOM). Large areas in these lakes are very shallow, so that either bottom reflectance (depths vary from 2 - 9 meters) or submersed vegetation add more complexity, making it difficult to monitor chlorophyll-a and TSS with both precision and accuracy. In other large lakes in the Canadian prairies (e.g. Lake Winnipeg and Lake of the Woods), local calibration using in situ data has been useful for retrieval of these parameters In the open water seasons in 2016 to 2017, surface and bottom water quality samples were taken at 43 stations throughout Lakes Manitoba, Winnipegosis and Waterhen. Sites were sampled three times per year (spring, summer and fall) to capture a variety of open water conditions. At selected sites, a field spectrometer (ASD fieldSpec Pro) was used to measure surface reflectance over the spectral range used by ocean colour satellites.

    James Bay Expedition 2021 Cruise Report
    (Centre for Earth Observation Science, University of Manitoba, 2022-04-13) Kamula, M.; Kuzyk, Z.; Mundy, CJ
    With funding support from NSERC ($168,000) and Oceans North ($126,000), a research consortium led by the University of Manitoba carried out an oceanographic research expedition to James Bay during August 1-17, 2021. The expedition is the first of two planned expeditions intended to update our knowledge of the oceanography of James Bay.

    James Bay Expedition 2022 Cruise Report
    (Centre for Earth Observation Science, University of Manitoba, 2023-06-06) Ausen, Emma; Fedirchuk, Grace; Mundy, CJ; Ehn, Jens; Kuzyk, Zou Zou A
    With funding support from NSERC and Oceans North NGO, a research consortium led by researchers at the Centre for Earth Observation Science (CEOS), University of Manitoba (UM), carried out an oceanographic research expedition to James Bay and nearby waters during July 20–August 26, 2022. This James Bay Expedition (JBE) 2022 was the second of two oceanographic research cruises to James Bay aboard the RV William Kennedy intended to update our understanding of the oceanography of this system. The first phase of the JBE took place in summer 2021 and accomplished oceanographic sampling throughout James Bay as well as deployment of five oceanographic moorings intended to monitor subsurface conditions for year-long periods. During summer 2022, the moorings were recovered and sampling was repeated at a number of stations throughout James Bay. The summer 2022 program also expanded oceanographic data coverage to include the waters surrounding the Belcher Islands in southeastern Hudson Bay, which receives outflow from James Bay.
