Exchange moorings at the LNB site and off Scituate. Collect sediment samples and oxygen profiles at our long-term monitoring stations.
Location
Massachusetts Bay, Scituate, Boston Harbor, Massachusetts, United States, North America, North Atlantic;
Summary
Moorings deployed: 4 (#689, 690, 691 and 692, all recovered FA 02046 MARCUS HANNA Oct. 22-25, 2002). Moorings recovered: 5 (#682, 683, 684, 685 and 686, all deployed FA 02026 MARCUS HANNA Feb. 5-6, 2002). 8 cores collected at Station 3; 2 cores collected at Station 2; 2 water samples recovered; 13 tube traps recovered/deployed. Recovered Anderson trap sample at LNB location - a good one; redeployed same at LNB location. Honjo traps recovered at LNB and Scituate - both worked; redeployed Honjo traps at same sites. WHOI scientists deployed/recovered oxygen profiler 2x at each USGS station (2 and 3). WHOI scientists deployed 2 SQUIRTS instruments (porewater sampling devices) near USGS Station 3 to be recovered 1 week later.

Comments
If the large tripod fails to come up, we will request an extra day of ship time to dive on the instrument. Problems (again) with the HDC core closure device (cheese slicer) - especially evident on Station 2.
