  • Description:
    The main goal of the 1993 BIE-II cruise was to create a sediment redeposition impact on the benthic community at the BIE study site located in the Pacific Ocean at 12° 56' N and 128° W. Our primary objectives on the 1993 BIE -II cruise were as follows: Establish a transponder net and collect baseline information on nodule coverage and m½gafaunal abundance from bottom photographs and side-scan sonar; Test five different pump configurations of the second generation Deep Sea Sediment Resuspension System (DSSRS-m at the Patton Escarpment test site off Long Beach, California; Collect baseline box core samples; Recover two Russian current meters and deploy an array of two Aanderaa current meters and 18 sediments traps within the study area; Create a large -scale redeposition event by towing the Disturber through a 150-m-x-3000-m tow zone; Map the resedimentation plume using sediment-traps and CTD casts; Collect post-disturbance box core samples to assess short -term impacts on meiofauna and macrofauna; Deploy 4 current meter moorings to obtain long-term information about the deep ocean currents in the BIE-II study area. The remainder of this cruise report details the results of each of these six objectives.
