Ross Sea Sulfur Compound Concentrations and Turnover Rates

Two research cruises aboard the RV Nathaniel B. Palmer collected water samples in the Ross Sea, Antarctica, during December 2004 to January 2005 and October to November 2005. The dataset contains concentration and biological turnover rate measurements for sulfur compounds, specifically dimethylsulfide (DMS) and dimethylsulfoniopropionate (DMSP). Samples were gathered from both the ship's underway system and CTD casts with Niskin bottle sampling at depths up to 737 meters.

Use Cases

• Analyzing spatial and temporal patterns of DMS and DMSP concentrations in Antarctic surface waters.
• Correlating sulfur compound turnover rates with biological activity from CTD and Niskin bottle sampling.
• Studying the vertical distribution of sulfur cycling using data from samples collected at depths up to 737 meters.
• Investigating the relationship between underway system surface water (4m intake) and deeper water column chemistry.

Strengths

• Data originates from two dedicated, instrumented research cruises (NBP04-09 and NBP05-08) providing controlled collection.
• Includes biological turnover rate measurements alongside concentration data for key sulfur compounds.
• Samples cover a vertical profile from surface (4m) to 737 meters depth via CTD casts.

Limitations

• Specific column names, row counts, and dataset size are unknown across all sources.
• Sources conflict on the last updated date, with one listing 2005-11-30 and another 2026-03-05.
