Summary of Activity and Data Gathered: physical data holdings Approximately 2,350-line km of multichannel seismic-reflection data, as well as 4,500 km of other geophysical profile data including gravity, magnetic gradiometer, and echo-sounding profiles for the western Ross Sea, Antarctica were collected. The seismic source consisted of a tuned five-airgun array totaling 1,311 cu.in. pressurized to 1,900 psi, towed at a depth of 10.5 m. The receiver consisted of a 24-channel hydrophone streamer, with 100-m group lengths containing 60 hydrophones in each group. The streamer was towed at a depth of 12.5 m. The data were recorded with a GUS Model HDDR-4200 recording system. All lines were recorded to 12 sec, with exception of Line 407 (15 sec) and Line 419 (8 sec). Magnetic data were recorded continuously with a Geometrics proton-procession gradiometer to remove the large temporal magnetic variations commonly recorded at polar latitudes. The gradiometer system consisted of two proton-precession magnetometers separated horizontally by 500 ft (152 m) with the forward sensor lying 225 m aft of the ship. Both sensors were towed at a depth of approximately 20-40m. Data were sampled at 4-sec intervals. Gravity data were recorded continuously with a LaCoste and Romberg sea gravimeter (S53) on a two-axis stabilized platform. The data were collected at 20-sec intervals and subsequently desampled to 2 min or greater for plotting and modeling.
