2006 data from the BROKE-West voyage of the Aurora Australis measures dimethylsulphide (DMS) and dimethylsulphoniopropionate (DMSP) concentrations in seawater. The dataset, created by the Australian Antarctic Data Centre (AU_AADC), includes results from CTD casts and minicosm experiments. Analysis of samples involved gas chromatography to determine dissolved and particulate concentrations.
Use Cases
- Analyze DMS Concentration (nM) against CTD Number and Niskin Bottle to study vertical profiles of volatile sulfur compounds.
- Model DMSP particulate concentration (nM) and DMSP dissolved concentration (nM) relationships from minicosm experiments using Minicosm Day and Hour.
- Correlate Tank Number with DMS Concentration (nM) in minicosm data to assess experimental treatment effects.
- Investigate sulfur compound dynamics by joining CTD and minicosm datasets on shared concentration fields.
Strengths
- Data covers a specific Antarctic research voyage (BROKE-West) from 2006.
- Provides three distinct concentration measurements (DMS, particulate DMSP, dissolved DMSP) per sample.
- Includes data from two complementary experimental setups: CTD casts and minicosm tanks.
Limitations
- Sample size and total row count are unknown.
- Data is from a single voyage in 2006, limiting temporal and spatial generalizability.
- Potential for measurement error inherent in complex purge-and-trap gas chromatography analysis.
