Sunny skies, light winds, calm seas. 3 270 930 Arrive on station off Westhampton Beach. Light winds, calm seas. 2 270 1030 Deploy fathometer plate and boomer system, begin tuning. 300 J boomer output. 1 270 1125 Deploy SIS-1000. Applied 3db gain to starboard channel to compensate for fish list. 1 270 1227 1 l1f1.dat 1 Start recording data. About 2900 meters downline, will go with it. Everything working fine, layback coming through just fine. Sidescan looks good, although boring (!). Mudseis is working fine. Starboard gain set to 3 db, port to 0 db, subbottom to 9 db with -6 db attenuation. Note that we are running both mudseis and xseismics. We are not logging specific file names in this log, as the system is in sort of a "debug mode." 2 270 1227 1 l1f1.sgy 1 Mudseis running fine. Outputting 300 joules, boomer sled is in. Filtering at 300-3000 Hz. 3 270 1227 1 data 1 Navigation going. Layback correction working properly, Benthos ranging great. All's well. 2 270 1240 1 l1f1.sgy 1 Intermittent problem with streamer.
