    • Winter Aircraft Profiles of Temperature, Salinity, Density, and Nutrients 1 - 16 April 2004 (NCEI Accession 0059292)

    Metadata Updated: April 1, 2025

    Early spring sampling was performed in the eastern area of the Shelf-Basin Interactions Project using aircraft. Flights began on 1 April 2004 and finished on 16 April. During this time, we sampled 32 sites on a series of 5 transect lines (Fig. 1). 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. Typically, 4 stations were sampled on each flying day. At each site, a Seabird SBE-19 CTD and a water sampling bottle was deployed through an 25 cm hole augered through the pack-ice. Continuous profiles of pressure, temperature, and salinity were made from the ice hole to either the sediment surface or to about 500 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. About 30 ml of seawater collected from the Niskin bottle were poured into a 50 ml clean dry polyethylene sample bottle. The nutrient sample bottles quickly froze and were kept that way until measurement of nitrate, nitrite, ammonium, phosphate and silicate by the Nutrient Chemistry Laboratory of the Scripps Institute of Oceanography.
