Deep-Water Fish Habitat Associations Across Cordell Bank

Cordell Bank in central California provides the spatial scope for this study of deep-water demersal fish abundance and distribution across three spatial scales. The dataset was created by the Australian Ocean Data Network, quantifying fish counts and benthic habitats from 60 strip-transects surveyed via submersible. It was last updated in April 2026.

Use Cases

• Model fish assemblage composition using broad-scale habitat zones like the rocky bank and transition zones as predictors.
• Predict taxon-specific fish abundance from fine-scale habitat characteristics measured at 1-10s of meters.
• Analyze the correlation between spatial location on the bank and demersal fish distribution patterns.
• Evaluate the use of acoustic seabed mapping data as a surrogate for predicting species abundance at regional scales.

Strengths

• Data collected from 60 systematically allocated strip-transects across the study area.
• Analysis spans three distinct spatial scales: broad (bank), intermediate (10-100s of m), and fine (1-10s of m).

Limitations

• Sample size is limited to a single deep-water bank (Cordell Bank), restricting geographic generalizability.
• The dataset's specific row count, column names, and sample size are unknown.
