Sulfur Compound Concentrations and Rates from Ross Sea Transects

Oceanographic data from the Ross Sea, Antarctica, includes concentrations and rates for dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), and dimethylsulfoxide (DMSO). The dataset was collected during two research cruises aboard the R/V Nathaniel B. Palmer in 2004-2005. It is provided by the organization SCIOPS.

Use Cases

• Modeling dimethylsulfide (DMS) sea-air flux using concentration data and accompanying CTD/GUV irradiance data.
• Analyzing relationships between sulfur compound concentrations (DMS, DMSP, DMSO) and biological data like bacterial biomass and productivity.
• Studying spatial gradients of sulfur compounds along the surface transect from New Zealand to the Ross Sea.
• Comparing sulfur cycling dynamics between the open transect and the Ross Sea Polynya using depth profile data.

Strengths

• Data from two dedicated research cruises (NBP04-09 and NBP05-08) providing temporal coverage.
• Includes multiple related data types: sulfur compounds, biological parameters, CTD, and irradiance measurements.

Limitations

• Exact sample size (row count) and number of measured features are unknown.
• Data is from 2004-2005 and may not reflect current oceanic conditions.
• Geographic scope is limited to a specific transect and the Ross Sea region.
