Night Recovery of the Multichannel Seismic System
Looking astern, the airgun sled is in its cradle in the center of the photo. The crew are manually recovering the multichannel streamer and beginning the large figure-8 shape of coiling it on deck. Work at sea occurs 24 hours a day. In late September, there is ~12 hours of night, resulting in gear recovery at night. This was final recovery of gear at the end of the
