Science Objectives

This cruise is a joint OSNAP East (Johns) and NISKINe (Alford/Waterhouse/Voet) cruise, focused on servicing or recovering critical moorings in the Iceland Basin.
The cruise has two primary objectives:
1. Turn around (recover and redeploy) 7 moorings in the OSNAP East array, and
2. Recover 3 NISKINe program moorings

Science Activities

Mooring operations (recovery and redeployment)
Limited CTD operations (at mooring sites prior to recovery, and for calibration of moored sensors)
