Long-term oceanic observatories (moorings) in the Beaufort Sea during ArcticNet study 2004-2010
Thirty-six moorings were deployed in the Beaufort Sea between 2004 and 2010. Some of the moorings were deployed for one year only and others were maintained (recovered and redeployed) over several years. A total of 12 moorings were lost (1 in 2004, 2 in 2006, 1 in 2007, 2 in 2008, and 6 in 2010). Mo...

| Summary: | Thirty-six moorings were deployed in the Beaufort Sea between 2004 and 2010. Some of the moorings were deployed for one year only and others were maintained (recovered and redeployed) over several years. A total of 12 moorings were lost (1 in 2004, 2 in 2006, 1 in 2007, 2 in 2008, and 6 in 2010). Mooring sites included the Mackenzie Shelf (North-Western to North-Eastern), Mackenzie Shelf slope, Kugmallit Valley, Canada Basin, Mackenzie Canyon, Amundsen Gulf (West to East), and outer Franklin Bay area. Bottom depth at deployment sites varied between 200 and 545 m. Mooring lines were equipped with various oceanographic instruments attached at different depths from 12 m to a maximum of 500 m below the surface. Moored instruments included ALEC conductivity-temperature-turbidity- chlorophyll-PAR sensors, SeaBird SB 26 and SB37 conductivity-temperature sensors, RMC4, RMC7 and RCM11 current meters, Nortek current profilers, McLane moored profilers and NIPR and Technicap sediment traps. The datasets available were quality controlled, and have been used in several publications listed in the document accompanying the data. Variables available include water temperature, conductivity (salinity), density, PAR, Chla, turbidity, oxygen and current velocity (speed and direction). Sediment trap collections were used to estimate downward fluxes of particles, and datasets are described in Metadata CCIN 10476 (Vertical particle flux data in the Beaufort Sea: 2002-2010). : Purpose: To monitor changes in physical, biological and geochemical properties of the Canadian Arctic waters, ocean observatories (moorings) were deployed in the Beaufort Sea as part of the ArcticNet field program. These moorings are the oceanic equivalent of atmospheric meteorological stations. The data are used to describe the seasonal and annual variations in the Arctic environment and its local ecosystems. This, in turn, enables us to understand how, and how quickly, global warming is affecting the Arctic : Summary: Not Applicable |
