USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2004-016-FA

Other ID: MH44-04

Status: Completed

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

Funding Program(s):

Location: Massachusetts Bay, Massachusetts, United States, North America, North Atlantic,

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s):

Information Specialist(s): Michael Casso, Frances Lightsom

Data Type(s): Environmental Data: CTD, Environmental Data: Dissolved Oxygen, Environmental Data: Temperature, Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology

Scientific Purpose/Goals: Exchange moorings at the Boston B Buoy. Recover moorings at the site off Scituate. On the second day, collect sediment cores and sediment-oxygen profiles at Stations 2 and 3.


Start Date: 2004-02-05

Start Port/Location: Coast Guard Base, Boston, MA

End Date: 2004-02-06

End Port/Location: Coast Guard Base, Boston, MA

Equipment Used: Oxygen profiling system from Sayles, Video camera - deep sea, Corer - piston, Grab sampler - Van Veen , Temperature and salinity, Digital camera, DGPS

Information to be Derived: Time series data; Samples and chemical analysis; Grain size analysis; Suspended sediment concentrations;

Summary of Activity and Data Gathered: This cruise was conducted in cold (20 degrees F) winds from the west (20-25 kts) on Day 1 and in snow, sleet and freezing rain on Day 2 (20 kts SE). The ship continues to be a major factor in the success of this operation. The scientific and ship crews worked hard and well together, as usual. Moorings deployed: 2 (#755 and 756 both recovered FA 04026 MARCUS HANNA May 19-20, 2004). Moorings recovered: 2 (#716 and 718 both deployed FA 03043 MARCUS HANNA Sep. 24-25, 2003). At Station A (near the Boston B Buoy) the subsurface mooring was exchanged and a refurbished large tripod was deployed. The tripod deployed in September did not come up. At Scituate, the NOPP subsurface mooring #734 (deployed FA 03057 CHRISTOPHER ANDREW Aug. 27, 2003) was recovered. The tripod did not come up. Divers will be scheduled to help recover instruments at both locations in the near future. Coring was successful at both Stations 3 and 2. One core was given to Joseph Smith at U. Mass. Boston for analysis of Iodine 131 and others to our WHOI colleagues for analysis of pore water. Other cores were returned to USGS for X-rays and analysis of texture, metals, Th234, etc.
