Standard ODP practice is to collect magnetometer and 3.5- and 12-kHz echo-sounder data during transit to each site. Additionally, we will conduct a short (<6 hr) single-channel seismic reflection survey using a 80-in3 Seismic Systems Inc. (SSI) water gun. The profile will run perpendicular (roughly east-west) to an existing north-south profile collected over Site 852 during Leg 138 (Shipboard Scientific Party, 1992b; Bloomer et al., 1992).
