Over three years of sampling from 1975-07-01 to 1978-09-30 captured physical, chemical, and biological parameters in Southern California coastal waters. The dataset includes depth, temperature, salinity profiles, hydrocarbon fractions, trace metal concentrations, sediment composition, and benthic fauna analysis. Science Applications, Inc. collected this data for the Bureau of Land Management's Southern California OCS Baseline Study.
Use Cases
- Modeling relationships between sediment grain size, total organic carbon (toc), and trace metal concentrations like Ba, Cd, Cr, Cu, Fe, Ni, Pb, V, Zn, and Al.
- Analyzing temporal trends in hydrocarbon (hc) concentrations, including aliphatic, aromatic, pristane, and phytane fractions, from 1975 to 1978.
- Classifying benthic community composition using data on benthic microfauna, macrofauna, and the biotic/abiotic mussel community.
- Correlating water column parameters like particulate organic carbon (poc), dissolved organic carbon (doc), and ATP with depth and salinity profiles.
- Assessing intertidal versus benthic zone differences in sediment age, calcium carbonate content, and mineral composition.
Strengths
- Multi-year temporal coverage from July 1975 to September 1978.
- Diverse data types covering physical profiles, hydrocarbon chemistry, trace metals, sediment properties, and biological communities.
Limitations
- Data is over 45 years old, limiting relevance to current environmental conditions.
- Specific sample sizes, row counts, and measurement frequencies are unknown.
- Geographic coverage is limited to coastal areas of Southern California.
