Objectives: Replace bottom tripod system (#157) deployed on ATLANTIS II 103 (FA 78031) suspected of malfunctioning; deploy additional surface marker buoy at station for additional protection from bottom trawling; attempt to recover by grappling subsurface current mooring #162. (Trawler OCEAN STATE from Pt. Judith, RI fished up entire mooring. Flotation was returned but 1 VACM-TR and release dropped to bottom when chain parted.)

Type of Activity: Mooring work
XBT, surface salinity samples

Information to be derived: Time series data
Samples and chemical analysis

Summary: Unable to recover Mooring #162 with grapple; instruments slipped from wire twice in rough seas; recovered small marker float only.
