Intertidal and Subtidal Ecological Surveys from 1974-1979

Eight standardized record types support physical and biological studies of coastal zones. Data includes station identification, sediment analysis, biological sample descriptions, species identification, individual fish examinations, and stomach content analysis. The dataset was submitted to the National Oceanographic Data Center (NODC) and last updated in 1979.

Use Cases

• Analyze sediment composition from sediment analysis records to correlate with species presence.
• Study fish diet and trophic levels by examining stomach contents records linked to individual fish examinations.
• Map species distribution and biodiversity using species identification records across different stations.
• Correlate biological sample descriptions with physical station data to model habitat suitability.

Strengths

• Structured into eight distinct 80-character record types for consistent parsing.
• Includes multiple data facets: physical sediment data, biological samples, and species-level examinations.

Limitations

• Data is temporally stale, with collection ending in 1979 and no recent updates.
• Unknown total row count and geographic scope limits assessment of statistical power.
• Data format is fixed-width (80-character records), which may require specific parsing logic.
