July 1997 to July 1998 data collected by the Minerals Management Service aboard the Research Vessel Alpha Helix. The dataset likely contains results from chemical, biological, and toxicological analyses of sediment samples from depositional areas in Shelikof Strait and outermost Cook Inlet. The principal investigator was Dr. Paul H. Boehm of Arthur D. Little, Inc.
Use Cases
- Assessing sediment contamination levels based on chemical analyses mentioned in the description
- Studying biological responses to pollutants based on biological measurements mentioned in the description
- Evaluating sediment toxicity based on toxicological analyses mentioned in the description
- Analyzing temporal changes in sediment quality between the 1997 and 1998 surveys
Strengths
- Data covers two distinct sampling surveys in July 1997 and July 1998
- Includes multiple analysis types: chemical, biological, and toxicological
- Specific geographic focus on Shelikof Strait and outermost Cook Inlet
Limitations
- Last updated 1998-07-05 00:00:00; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
