During the 1991 R/V Polar Duke cruise, data were collected along the Weddell Sea margin of the Antarctic Peninsula (Fig. 1). Approximately 2000 km of seismic data were acquired using a 100 in3 water gun, fired at a 6 second shot interval, and an oil-filled streamer. The data were collected in analog format on an electrostatic plotter, and in digital format using Elics® single channel seismic acquisition and processing software. The low-cut filter was set to 20 Hz; the high cut filter was set to 4000 Hz. Ship speeds ranged between 4 to 7 knots. Navigation relied on the GPS, with brief periods of satellite navigation.
