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.
