2003 Helo Survey CTD Data [Christensen, J. and H. Melling]
Early spring sampling was performed in the eastern area of the Shelf-Basin Interactions Project using aircraft. Flights began on 1 April 2003 and finished on 15 April. During this time, we sampled 42 sites (49 Conductivity, Temperature, Depth (CTD) casts) on a series of 5 transect lines which bracketed and were parallel to the SBI current meter mooring line located at 152 degrees W longitude. Stations were about 10 km apart along each transect line. Transect lines B, C, and D were at the same spacing; while, lines A and E were 20 km from the nearest transect line. A map of the achieved sampling sites is available (file: SW3LOC4A.pdf). Typically, 4-5 stations were sampled on each flying day. At each site, a Seabird CTD (either a SBE-19 or an SBE-25) and Satlantic ISUS nitrate analyzer with a water sampling bottle was deployed through an 8 inch hole augured through the pack-ice. Continuous profiles of pressure, temperature, salinity, and nitrate concentrations were made from the ice hole to either the sediment surface or to about 390 m. CTD data were processed with Seabird software (Seasoft) and the data binned into 0.5 dbar layers. Data herein are the vertical profiles of temperature, salinity, and density. Nutrient data are not reported here.
