Grain size analysis data for marine sediments were collected in the Chukchi Sea and NW Coast of Alaska. The dataset includes sediment properties, dry weight, and particle size fractions. Data were submitted by the University of Alaska Fairbanks Institute of Marine Science and collected between August 29, 1986, and October 7, 1987.
Use Cases
- Analyze sediment particle size fractions to classify seabed types and map depositional environments.
- Correlate sediment dry weight measurements with grain size data to assess sediment compaction and porosity.
- Use sediment property data to establish baseline conditions for assessing contaminant discharge impacts from outer continental shelf activities.
- Study temporal changes in grain size distribution over the 13-month collection period for coastal dynamics research.
Strengths
- Data collection spans a 13-month period from August 1986 to October 1987.
- Includes multiple measured sediment properties: grain size fractions, dry weight, and other characteristics.
Limitations
- Sample size and row count are unknown, limiting statistical power assessments.
- Data is over 35 years old and may not reflect current sediment conditions.
- Geographic coverage is limited to the Chukchi Sea and NW Coast of Alaska.
