Objectives

The goals of cruise D345 were to:
1. Service the U.S. moorings within the western boundary array of the RAPID/MOCHA transbasin observing system. This includes three taut wire subsurface current meter/CTD moorings, and two bottom-lander moorings containing high-precision bottom pressure gauges.
2. Conduct hydrographic (CTDO2) and direct current profiling (lowered-ADCP ie LADCP) stations along the 26.5º N mooring section off Abaco, Bahamas; and across the Northwest Providence Channel, including continuous shipboard ADCP observations.
3) Service three bottom pressure/inverted echo sounder (PIES) moorings and retrieve data from two additional PIES moorings via acoustic telemetry.
