Amundsen Science BaySys Cruise, Leg 1/2/3, 2018

Leg 1 of the 2018 Amundsen cruise was successful. Many of our objectives for the cruise and BaySys project were achieved, baring a few locations in the bay in which were not able to access due to ice and weather conditions. Overall, data collection and sampling went well, including all on board and remote based (i.e., helicopter; zodiac; barge; and on-ice) operations.

The cruise provided immense value to the BaySys project. It allowed for large-scale data collection throughout a partial ice-covered Hudson Bay that would otherwise have been impossible via most other modes of fieldwork (i.e., land and ice-camps; small vessel sampling; pedestrian survey and data collection). The data collected throughout Hudson Bay ensures that we have comparative results to past fieldwork, as well as provides physical inputs for the BaySys modeling teams. In addition, community visits provided those on board with important experience in science communication and involvement with local communities, including elders, officials, and youth. The impressive amount of samples and data collection over six weeks, and the results that will derive from their analysis ultimately help BaySys teams achieve their goals and provide insight towards answering the overall project objectives to separate climate change effects from those of hydroelectric regulation of freshwater on physical, biological and biogeochemical conditions in Hudson Bay.

Field Value
Abstract This dataset consists of CTD results from Leg 1, 2018 of the BaySys Cruise, conducted on the CCGS Amundsen. The rosette has twelve sampling water bottles and several instruments attached to its frame to collect water samples and records physical and chemical data (temperature, conductivity, pressure, fluorescence, light transmission, nitrate, photosynthesis) with sensors. The water samples are distributed to the scientific teams for in-situ analysis. In-situ data belong to and are under the responsibility of the leading scientists while physical and chemical data from the sensors are part of the Amundsen core data collection. Data typically measured each year and provided in this archive are as follows: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), dissolved oxygen (Sea-Bird SBE-43), fluorescence (Seapoint chlorophyll fluorometer), CDOM (Wetlabs FL(RT)D), nitrate concentration (Satlantic MBARI-ISUS 5T), transmittance (Wetlabs C-Star transmissometer), light intensity (PAR; LI-COR Biosciences) and surface light intensity (sPAR; LI-COR Biosciences). Quality control procedures are applied to the data which are available under these formats: .int (one cast by file), .odv, .kml, .btl and .odf (on demand).
