SCIOPS collected this dataset on the ANT XIII-3 cruise aboard the RV Polarstern in the southeastern Weddell Sea. Sampling involved 13 Agassiz net trawls, 10 demersal trawls, and 4 benthopelagic net operations at depths from 123 to 2334 meters. The dataset includes material for studies of fish age, growth, diet, and fecundity.
Use Cases
- Modeling species distribution by depth using the 123-2334 meter sampling range.
- Analyzing trophic relationships and diet composition from the collected diet analysis material.
- Studying population age structure and growth rates using the age and growth study material.
- Investigating reproductive biology through the fecundity analysis samples.
Strengths
- Sampling covers a significant depth gradient from 123 to 2334 meters.
- Multiple gear types (Agassiz net, demersal trawl, benthopelagic net) used for collection across 27 total operations.
Limitations
- The dataset is from a single cruise in 1996, limiting temporal analysis.
- Sample size and specific row/column counts are unknown.
- Geographic coverage is restricted to the southeastern Weddell Sea slope.
