Benthic taxonomy and biomass data were collected during the ISHTAR Project in the Bering and Chukchi Seas. The dataset was gathered by the R/V Alpha Helix and submitted by NOAA's National Centers for Environmental Information. Observations span from 1984 to 1990.
Use Cases
- Analyze species composition changes over the 6-year period using taxonomic classification fields.
- Model benthic biomass distribution across the Bering and Chukchi Seas using geospatial coordinates.
- Correlate benthic community metrics with environmental variables from the ISHTAR Project's broader data collection.
- Establish historical baselines for species abundance by examining biomass measurements per taxonomic unit.
Strengths
- Data collection spans a 6-year period from 1984 to 1990.
- Covers two major Arctic seas: the Bering and Chukchi Seas.
- Includes two distinct data types: taxonomic identification and biomass measurements.
Limitations
- Sample size and row count are unknown.
- Data is over 30 years old, limiting analysis of recent ecological changes.
- Specific column names and data granularity are not provided.
