Summary of Activity and Data Gathered: 13 lines were run normal to the coastline between 33 N and 29 30 N. Two lines comprised one long tie-line parallel to the shelf break. In addition, four short lines were run in the area between latitude 30 40 N to 31 10 N and longitudes 80 30 W to 80 W. The lines and numbering system was continued from FAY Cruise 017 to the north at 18. Lines on 018 were numbered from 18 to 32 and the dogleg following each line was considered part of the preceeding line. 12 sonobuoy refraction profiles were completed along lines 31 and 32, all on the Blake Plateau. Sonobuoy stations were numbered from 2 to 13 with #2 on the north and #13 on the south. 3.5 kHz: 2515 km; Sparker: 2808 km; Airgun: 3019 km; Sonobuoy: 12 stations, 268 km; Magnetics: 3019 km; Gravity: 2848 km.
