Scientific Purpose/Goals: To sample and groundtruth the 1993 Acoustic data especally the sidedscan sonar mosaic of the seafloor of Mamala Bay over the US Corps of Engineers Deep Ocean dredged material Disposal Sites used by Pearl and Honolulu Harbors. Use box core samples to determine the chemical and physical effects and anthropogenic stresses placed on the seafloor and near-surface substrate of Mamala Bay, Honolulu, Oahu, Hawaii. The samples will be used to determine the toxicological and chemical effects of dredged material disposal on the ecosystem as well. Follow-up surveys addreessing the infauna will be conducted in 1995.

Information to be Derived:
Summary of Activity and Data Gathered: 71 box core stations occupied in Mamala Bay, Honolulu, Oahu, Hawaii with 65 recoveries. Cores photographed and slab taken from cores also x-rayed for structure. Dredged material visible in many cores on and off the disposal sites. Subsamples collected for toxicological analyses and anthropogenic effects including: extractable heavy metals, organics, inorganics, pcbs, pesticides, mineralogy, grain size, total- organic- and carbonate carbon.
