Field Activity Details for field activity 1978-035-FA

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Bradford Butman

Information Specialist(s):

Data Type(s): Environmental Data: Temperature, Imagery: Photo, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: 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.)

Vehicle(s):

Start Date: 1978-10-30

Start Port/Location: Woods Hole, MA

End Date: 1978-11-02

End Port/Location: Woods Hole, MA

Equipment Used: XBT, Camera- deep sea, Bottom tripod

Information to be Derived: Time series data; Samples and chemical analysis;

Summary of Activity and Data Gathered: Unable to recover Mooring #162 with grapple; instruments slipped from wire twice in rough seas; recovered small marker float only. Mooring recovered: 1 (#157 deployed FA 78031 ATLANTIS II Sep. 28 - Oct. 5, 1978). Moorings deployed: 2 (#166 and 167, recovered FA 79002 OCEANUS 56 Mar. 6-15, 1979). XBT stations: 4; Surface salinity samples: 4.
