Integrated Beaufort Observatory (iBO) mooring data, 2015-2018

The main integrated Beaufort Observatory (iBO) sampling platform is composed of 7 tautline moorings located in waters ranging from 20 to 750 m at key locations from the Mackenzie Canyon, to the mid and outer central shelf and slope, up to the remote northwestern area off Banks Island. BR-G, BR-K, BR-1 and BR-3 moorings are under the responsibility of ArcticNet while DFO-1, DFO-2 and DFO-9 are under the Institute of Ocean Sciences (DFO) responsibility. Moored instruments include acoustic doppler current profilers from 75 to 2000 MHz to measure current velocity, current direction, ice drift and plankton/particulates backscattering; ice-profiling sonars for the measurement of sea ice thickness, under-ice topography and for assessing waves and storm surges; water property sensors for salinity (S), temperature (T), turbidity, chlorophyll and dissolved oxygen; and automated sediment traps that collect sinking particles for the measurement of biogeochemical fluxes. 2015-2018 ArcticNet data will be quality assessed/quality controlled (QA/QC) and publicly available through the Polar Data Catalogue in 2022. The moorings were deployed and will be recovered from the CCGS Amundsen and Laurier Icebreakers.
