Tomales Bay Water Quality Measurements from Shore, 1967-1970

Tomales Bay Water Quality data was collected by the Pacific Marine Station from May 1, 1967, to February 25, 1970. Observations were made from shore using the vessel R/V Crago, with positions determined by sighting from shore stations. The principal investigator for the program was Dr. Edmund H. Smith.

Use Cases

• Modeling temporal trends in bacterial density based on bi-weekly sampling.
• Analyzing relationships between particulate organic carbon and other water quality parameters.
• Studying coastal water quality variability over a multi-year period from 1967 to 1970.
• Assessing positional accuracy for historical environmental sampling based on fixed shore features.

Strengths

• Data collection spanned nearly three years, from May 1967 to February 1970.
• Sampling locations were re-sampled approximately every two weeks, providing regular temporal coverage.
• Positional accuracy for relocating sampling sites is documented as within 50 feet.

Limitations

• Last updated 1970-02-01 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.
