May to October 1982 sampling of bottom-dwelling marine organisms in the Gulf of Mexico. Data includes species abundance, distribution, and biomass from sediment sampler casts aboard the CAPT. BRADY J and CAJUN SPECIAL vessels. The dataset was submitted by McNeese State University as part of the Brine Disposal project.
Use Cases
- Analyze species_abundance and total_weight per species to model historical benthic biomass distribution.
- Correlate species_distribution data with reported environmental variables like sediment_characteristics or bottom_temperature.
- Use station_positions and times to map the spatial and temporal coverage of the 1982 survey.
- Study cruise_information such as vessel, investigator, and institution to contextualize historical marine research methods.
Strengths
- Data collection spans a defined 6-month period from May to October 1982.
- Includes multiple data dimensions: species counts, weights, environmental conditions, and cruise metadata.
Limitations
- Dataset is from a single year (1982) and may not reflect current conditions.
- Sample size and geographic coverage within the Gulf of Mexico are unspecified.
