Summary: Moorings deployed: 4 (#689, 690, 691 and 692, all recovered FA 02045 MARCUS HANNA May 21-22, 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.

USGS Project Number: 67013 for those marked *, and 67011 for others
