Patagonian Sea Star Distribution from 1978 Expedition

Asteroid material was collected from the south Argentinian coasts between 40°S and 50°S during the Walter Herwig 1978 expedition. The dataset documents the distribution of Patagonian sea stars, primarily gathered using Agassiz trawls. It was compiled by the organization SCIOPS and last updated in 1978.

Use Cases

• Analyze species_distribution patterns across the latitudinal gradient from 40°S to 50°S.
• Study historical biodiversity by examining collected_asteroid_material records.
• Correlate collection_method, such as Agassiz trawl use, with species occurrence data.

Strengths

• Data is tied to a specific scientific expedition, the Walter Herwig 1978 expedition.
• Spatial coverage is clearly defined as the south Argentinian coast between 40°S and 50°S.

Limitations

• The dataset is temporally stale, with a last update date of 1978.
• Key quantitative details like row count, column names, and sample size are unknown.
