The Sea Ice Physics and Ecosystem eXperiment (SIPEX) collected 31 paired under-ice irradiance measurements and ice core samples from 12 stations off East Antarctica in September-October 2007. AU_AADC likely compiled the dataset, which includes high-resolution irradiance spectra and measurements of snow thickness, ice core length, and algal pigment concentrations. Data collection occurred during the SIPEX cruise in the 115-130 degrees E sector.
Use Cases
- Modeling light transmission through sea ice based on under-ice irradiance spectra
- Analyzing relationships between ice algal pigment composition and ice core physical properties
- Studying bio-optical variability across composite first-year ice floes of different sizes
- Calibrating remote sensing algorithms for Antarctic sea ice using field-collected optical data
Strengths
- 31 paired measurements provide a basis for correlating optical and biological properties
- High-resolution irradiance spectra recorded from 300-900 nm with 3.3 nm bandwidth
- Sampling protocol ensured sites were level and free of surface deformations within a 20 m radius
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
