Information to be Derived:

Summary of Activity and Data Gathered: We took a total of 25 piston cores for MBARI in three different environments: a heavily pockmarked area off Big Sur, a feature identified as "Smooth Ridge" in western Monterey Bay, and the head of Monterey Canyon. We experienced the worst sea conditions of our cruises during this time and lost about one day of work. The remainder of the time was very successful, however, providing plenty of sample to use in collaborative studies of sedimentology and geochemistry. The last day of our field work was spent in Monterey Bay taking eight box cores for Jon Kolak. Roger Lewis will be using Pb-210 methods to determine accumulation rates, and Jon will be looking at geochemical tracers to estimate the original source of the sediment.
