Notes -
related field activity -- O-1-99-SC (geophysics)
for first 2 days of O-2-99-SC
The next five days were committed to the Los Angeles Shelf Pollution and
Waste Disposal Project. The goals of our project are to understand the
sedimentology and oceanography of Santa Monica Bay, one of the most
human-impacted offshore areas on the West Coast, and to use this
understanding to forecast the fate of contaminated sediment. This is
our last major sampling year, and we used this opportunity to obtain
cores for a broad variety of purposes. In all, we acquired 20 piston
cores, 15 vibracores, 31 box cores, 6 grab samples, and one very smelly
Kasten core from a "sludge" deposit. We will be dating the piston,
box, and vibracore samples using Pb-210 and C-14 techniques to develop
a better understanding of sedimentation conditions in Santa Monica
Bay during the late Holocene with special emphasis on the last 100 years.
Chris Sommerfield, a USGS post-doc at Woods Hole, is focusing on the
last few thousand years, and Clark Alexander, as part of a coop with
the Skidaway Institute of Oceanography, is considering the last 100
years. A bottom photograph was taken with each box core using Hank
Chezar's camera system. A representative of the City of Los Angeles,
Department of Sanitation, participated in one day of the cruise, sampling
box cores for living things. Jon Kolak, a USGS post-doc in Menlo Park,
sampled some stations as part of a study of hydrocarbons in sediment.
The grab samples were taken for Pete Dartnell, who is working to use
acoustic backscatter measurements as a measure of habitat. Five cores
were taken for the Southern California Coastal Water Research Project
to be analyzed for pesticides and metals. Our sampling work in Santa
Monica Bay was hugely successful, and we now have adequate sample
resources to complete our study.
