Biological/Chemical Survey of Texoma and Capline Sector Salt Dome Brine Disposal Sites Off Louisiana, 1978-1979. Volume V. Describe Surficial Sediments and Suspended Particulate Matter

摘要

Measurements are summarized of surficial and suspended sediment characteristics which were made during four cruises to the West Hackberry and Weeks Island brine disposal sites in June and October of 1978 and January and May of 1979. The sites showed significant differences in sedimentology with the West Hackberry site being composed predominantly of fine-grained silt and clay with characteristically high levels of total organic carbon (TOC). Conversely, sediments at Weeks Island were primarily silty sand with low levels of organic carbon. Total organic carbon showed a significant inverse correlation with grain size (TOC increased with decreasing grain size).
