San Francisco Bay Sediment Toxicity Survey with Hydrocarbon Measurements

Survey results detail sediment toxicity in San Francisco Bay using multiple bioassay techniques. Data collection occurred over a focused three-month period from January to March 1990. The survey was conducted by Advanced Technology, Inc. and Toxscan, Inc./Kinnetic Laboratories, Inc. for a NOAA Quick Reaction Task Order.

Use Cases

• Analyze correlations between total resolved hydrocarbons concentration and sediment toxicity bioassay results.
• Map the spatial distribution of PCB and other CAS parameter code measurements across San Francisco Bay fixed stations.
• Model temporal changes in contaminant levels during the January to March 1990 sampling window.

Strengths

• Data includes results from multiple bioassay techniques for assessing sediment toxicity.
• Temporal coverage is precisely defined from 1990-01-04 to 1990-03-15.

Limitations

• Sample size and number of measurement stations are unknown, limiting statistical power assessment.
• Data is over 30 years old, which may not reflect current environmental conditions.
• Original file format (Macintosh Excel) may present compatibility challenges with modern software.
