Deep-Water Fish Habitat Associations at Cordell Bank, California

Cordell Bank, a deep-water bank in central California, is the study area for this dataset on demersal fish-habitat relationships. Data was gathered from 60 strip-transects using in situ observer and video-recorded data from the two-person Delta submersible. The study examines fish distributions and assemblage composition across three spatial scales to evaluate habitat as a proxy for predicting species abundance.

Use Cases

• Modeling species distribution based on habitat surrogates mentioned in the description
• Analyzing fish assemblage composition across multiple spatial scales (broad, intermediate, fine)
• Predicting fish abundance patterns in complex seabed environments like rocky banks and transition zones

Strengths

• Data collection involved 60 strip-transects over the extent of Cordell Bank
• Analysis covers three distinct spatial scales, from 1-10s of meters to 100s of meters
• In situ data was gathered using a two-person Delta submersible, combining observer and video-recorded methods

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Freshness should be verified; last metadata update was 2026-04-20 02:36:22.658543
