In spite of moderate winds and seas, participants in the spring ECOGIG mooring and lander cruise accomplished nearly all of the cruise goals.  These included the recovery, refurbishment, and re-deployment of a mooring at two separate sites.  The moorings included sediment traps, a single-point current meter, an ADCP, and a camera-equipped sediment trap for measuring in situ particle sinking speeds.  All of these systems worked perfectly, providing considerable amounts of data and samples for analyses. Three mini-landers were deployed at a separate site using the new lander-launcher system and this too went extremely well, with each of the landers being placed within a few meters of the target locations. The third objective was to collect vertical profiles of marine snow abundance using a digital camera system.  Four profiles from the sea surface to the seafloor were collected at three sites.  Next on the schedule is a cruise under the leadership of Arne Diercks on which the three mini-landers will be recovered and redeployed.
