A 2006 research cruise aboard the icebreaker Oden collected underway measurements along the western Antarctic coastline from Punta Arenas, Chile to McMurdo Station. The dataset includes continuous digital sampling of seawater for temperature, salinity, chlorophyll, pH, dissolved oxygen, CDOM fluorescence, nitrate, phosphate, and iron, alongside discrete samples for carbon, microplankton, and pigments. The project was conducted by SCIOPS to establish a baseline for understanding sea ice edge dynamics and their influence on primary and secondary production.
Use Cases
- Correlate sea ice edge position with primary production metrics like total chlorophyll and phytoplankton counts.
- Model larval krill dynamics using concurrent measurements of secondary production, nitrate, phosphate, and iron concentrations.
- Analyze the relationship between physical ocean properties (temperature, salinity) and biogeochemical markers (pH, dissolved oxygen, CDOM fluorescence).
- Validate satellite ocean color data using in-situ HPLC pigment structure and total chlorophyll measurements from the transect.
- Investigate carbon cycle dynamics in the Southern Ocean using total carbon discrete sample data alongside continuous underway measurements.
Strengths
- Data covers a major transect along the entire western Antarctic coastline, a significant geographic scope.
- Includes a multi-parameter suite of continuous (e.g., temperature, salinity) and discrete (e.g., HPLC pigments) measurements for cross-validation.
Limitations
- Exact sample size, row count, and temporal resolution within the 2006 cruise are unknown.
- Data is from a single cruise in 2006, limiting analysis of interannual variability or long-term trends.
