Mooring data of the Integrated Beaufort Observatory (iBO), a project from the Beaufort Regional Environmental Assessment (BREA) Marine Observatories in the Canadian Arctic.

The integrated Beaufort Observatory (iBO) project is an element of the Beaufort Regional Environmental Assessment (BREA) Marine Observatories in the Canadian Arctic. The project aims at consolidating the monitoring of crucial oceanographic and environmental parameters collected in the Beaufort Sea since 2009 through diverse initiatives related to the environmental assessment of exploration drilling in the Beaufort Sea (see CCIN 11925 - ArcticNet-Industry 2009-2011 moorings and CCIN 11975 - BREA 2011-2015 moorings).More specifically, the Amundsen Gulf region, also known as the 'Cape Bathurst Polynya', was previously identified as an area of increased biological activity due to an earlier retreat of sea ice in spring and frequent upwelling of nutrient-rich waters that develops along Cape Bathurst and near the eastern edge of the Mackenzie Shelf. The iBO moorings (BRG, BRK, BR1, and BR3) helped form three shelf-slope arrays that examine the spatial variability in shelf-slope processes in the southeastern Beaufort Sea. These moorings continue a long-term integrated observation of ice, water circulation, and particle fluxes established in the southern Beaufort Sea.BREA is supported by the Environment Studies Research Fund (ESRF), Imperial Oil Resources Ventures Limited, the Program on Energy Research and Development (PERD), and Fisheries and Oceans Canada (DFO). The iBO project is maintained via collaboration among ArcticNet, Amundsen Science, Fisheries and Oceans Canada, and Golder Associates. The Canadian Coast Guard has provided at-sea support using the icebreakers CCGS Amundsen and CCGS Sir Wilfrid Laurier.
