Deployment 3: *UPDATED 2020-04-28: This mooring was recovered 2018-12-09 which was a year later than originally intended. Some instruments were able to continue sampling for the extended deployment.* Recovery of the mooring was planned during the NBP 17-09 cruise (Nov - Dec 2017) but not completed due to adverse weather conditions. Recovery options are pending. Instruments that are still operational are likely reaching (or have surpassed) their deployment lifespan.
