Weddell Sea ice cores and optical measurements collected during the RV Polarstern PS117 voyage from December 2018 to January 2019. The dataset includes measurements of position, snow thickness, ice thickness, temperature, salinity, nutrients, and chlorophyll-a, alongside hyperspectral irradiance readings. It was contributed by the organization AU_AADC.
Use Cases
- Modeling sea ice thickness and salinity profiles based on core measurements
- Analyzing chlorophyll-a pigment content to assess under-ice phytoplankton biomass
- Studying light penetration in polar waters based on hyperspectral irradiance data
- Correlating macro-nutrient concentrations with ice core temperature profiles
Strengths
- Data collected during a dedicated research voyage (PS117) in the Weddell Sea
- Includes both physical ice core properties and hyperspectral optical measurements
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
