Physical and biogeochemical processes cause oceanic CO2 distributions to be regionally variable, differing with temperature and salinity. Because of this, regional CO2 flux determination is necessary to account for this variability and better constrain global carbon flux estimates. The distinctly cold temperatures and relatively fresh waters of the Arctic Ocean, including Southern Hudson Bay and James Bay (SHB-JB), contribute to additional oceanic CO2 uptake capacity relative to other regions, influencing their potential to be globally important atmospheric CO2 sinks. Despite this, SHB-JB remain understudied with respect to the carbonate system. \r\n\r\nTo address this gap, we measured SHB-JB surface water CO2 partial pressure (pCO2), salinity, and temperature for three-week periods in August from 2021-2023. Surface water pCO\u00ac2 varied within and between years. Mean pCO\u00ac2 (456, 454, 477 \u03bcatm) exceeded atmospheric CO2 concentrations (~416 \u03bcatm) in each year sampled. A strong correlation between surface water pCO2 and temperature was observed resulting in heightened pCO2 concentrations near areas where seawater is overlain by warm, fresh river inflow. The mean calculated CO2 flux from the ocean to the atmosphere were 2.75 \u00b13.78, 1.48 \u00b13.33, and 3.67 \u00b13.74 mmol CO2 m-2 day-1 for 2021-2023, respectively. The surface water of SHB-JB acts as a weak source of CO2 to the atmosphere during the late summer, contrary to what is observed in open arctic waters.", "num_resources": 1, "num_tags": 5, "organization": {"id": "9e21f6b6-d13f-4ba2-a379-fd962f507071", "name": "ceos", "title": "Centre for Earth Observation Science", "type": "organization", "description": "The Centre for Earth Observation Science (CEOS) was established in 1994 with a mandate to research, preserve and communicate knowledge of Earth system processes using the technologies of Earth Observation Science. Research is multidisciplinary and collaborative seeking to understand the complex interrelationships between elements of Earth systems, and how these systems will likely respond to climate change. Although researchers have worked in many regions, the Arctic marine system has always been a unifying focus of activity.\r\n\r\nIn 2012, CEOS, along with the Greenland Climate Research Centre (GCRC, Nuuk, Greenland) and the Arctic Research Centre (ARC, Aarhus, Denmark) established the Arctic Science Partnership, thereby integrating academic and research initiatives.\r\n\r\nAreas of existing research activity are divided among key themes:\r\n\r\nArctic Anthropology/Paleoclimatology: LiDAR scanning and digital site preservation, archaeo-geophysics, permafrost degredation, lithic morphometrics, zooarchaeology, proxy studies, paleodistribution of sea ice, landscape learning, Paleo-Eskimo culture, Thule Inuit culture, ethnographic analogy, traditional knowledge, climate change and northern heritage resource management.\r\n\r\nAtmospheric Studies/Meteorology: Boundary layer, precipitation, clouds, storms and extreme weather, circulation, eddy correlations, polar vortex, climate, teleconnections, geophysical fluid dynamics, flux and energy budgets, ocean-sea ice-atmosphere interface, radiative transfer, ice albedo feedback, cloud radiative forcing, pCO2. \r\n\r\nBiogeochemistry: Organic carbon, greenhouse gases, bubbles, Ikaite, carbonate chemistry, CO2 fluxes, mercury and other trace metals, minerals, hydrocarbons, brine processes, otolith microchemistry, sediments, biomarkers. \r\n\r\nContaminants: Mercury, trace metals, PAHs, source, transport, transformation, pathways, bioaccumulations, marine ecosystems, marine chemistry. \r\nEarth Observation Science: Active and passive microwave, LiDAR, EM induction, spatial-temporal analysis, forward and inverse scattering models, complex permittivity, ocean colour, ocean surface roughness, NIR, TIR, satellite telemetry, GPS.
