Abstract : This report summarizes Leg 8 of Expedition Seven Tow, conducted by the R/V THOMAS WASHINGTON from Adak, Alaska, to Astoria, Oregon, during 26 July-17 August 1970. Near bottom studies of the Aleutian Trench near 173 deg W and two geomagnetic profiles over anomaly 10 near 50 deg N by 140 deg W were completed using the deep tow geophysical system. The equipment innovations included towing the deep tow fish at 7300 meters depth and operating an echo sounder digitizer for direct computer input.
