Physical, chemical, and biological data collected during two research cruises in the Ross Sea, Antarctica from December 2004 to January 2005 and October to November 2005 for Ross Sea Sulfur Dynamics study (NODC Accession 0117322)

This dataset contains transect data from two research cruises to the Ross Sea, Antarctica, aboard the RV Nathaniel B. Palmer (NBP) in December 2004 to January 2005 (NBP04-09) and in October to November 2005 (NBP05-08). Water samples were collected from the ship's underway pumping system in the aft laboratory, which has an intake at 4 m depth, and from CTD casts with Niskin bottle sampling (up to 737 m). Samples were analyzed for concentration and biological turnover rate of sulfur compounds, particularly dimethylsulfide (DMS) and dimethylsulfoniopropionate (DMSP).

Purpose: To improve our understanding of the biogeochemical dynamics of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), and dimethyl sulfoxide (DMSO) in the Ross Sea, Antarctica, and to evaluate the impact of ultraviolet radiation and dissolved nutrients on organosulfur cycling in these waters.
