Summary: Moorings recovered: 2 (#776 and 777 both deployed FA 05003 MARCUS HANNA Feb. 9, 2005). Moorings deployed: 3 (#786 and 788 both recovered FA 05038 MARCUS HANNA Sep. 28-29, 2005; #787 part washed ashore Cohasset May 26, 2005, remainder recovered FA 05023 LOONEY Jun. 3, 2005). A large tripod with azide Honjo bottles and two Anderson traps, a small tripod, and a small subsurface mooring with formalin Honjo bottles were deployed on 5/18/05. Anderson trap 514 had the timer and the sodium azide poison. All traps were lost shortly after deployment due to strong NE storms. A large subsurface mooring was redeployed on 6/7/05. Two cores were taken at Station 2 and four cores were taken at Station 10 on 5/18/05. Two cores were taken at Station BH3 and seven cores were taken at Station 3 on 5/19/05. The oxygen sensor and the benthic chamber were deployed twice on 5/19/05. The ship had engine trouble requiring the coring of Station 4 to occur at a later time.
