Cordell Bank, a deep-water bank in central California, is the study area for this dataset on demersal fish assemblages. The data was collected via 60 strip-transects using a two-person Delta submersible, with observations from in situ observers and video recordings. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-05.
Use Cases
- Modeling species distribution based on habitat composition and spatial location correlations described in the study.
- Analyzing fish assemblage organization across multiple spatial scales (broad, intermediate, fine) as detailed in the description.
- Evaluating the use of acoustic seabed mapping data as a surrogate for predicting fish abundance patterns.
- Studying taxon-specific responses to fine-scale habitat heterogeneity within broader landscape configurations.
Strengths
- Data collection involved 60 strip-transects, providing systematic spatial coverage.
- Observations integrate in situ observer counts and video-recorded data from a submersible.
- Analysis covers three distinct spatial scales (broad, intermediate, fine) for habitat and fish associations.
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 as the last update timestamp is 2026-06-05 07:06:27.987986.
