Oxygen isotopic ratio measurements from sea ice, brine, snow, and seawater collected during the SIPEX II voyage in Antarctica. Data includes sampling station names and dates, with analysis precision of ±0.02 parts per thousand. The dataset was collected by the Aurora Australis in 2012 and analyzed at Hokkaido University.
Use Cases
- Tracking sea ice meltwater sources based on oxygen isotopic ratios from ice cores.
- Analyzing brine and seawater salinity relationships based on isotopic data from sackholes and water samplers.
- Modeling snow contribution to sea ice mass based on isotopic measurements of collected snow samples.
- Investigating temporal changes in sea ice composition based on station dates and isotopic values.
Strengths
- Analysis precision is explicitly stated as ±0.02 parts per thousand.
- Detailed sampling methodology is documented for ice cores, brine, snow, and seawater.
- Data is associated with a specific scientific voyage (SIPEX II) and year (2012).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
