Operations Area: Northwest Atlantic

Lat/Lon: 37° 33.8′ N / 50° 0.5′ W

Depth Range: 2443 / 5392

Will the vessel be operating within 200 NM of a foreign country? no

Science objectives

Annual service of three DART buoys in the north Atlantic. The DART buoys are the Deep-Ocean Assessment and Reporting of Tsunami station used for the early detection of tsunamis and to acquire data for real-time inudation forecasting.

Science Activities

Deploying three buoys with complete mooring, recover and deploy three bottom pressure recorders, recover one mooring and possibly recover 1-2 drifting buoys (depending upon their position). In addition, a full ocean depth CTD cast is required at each station, along with current profiles within a 60 nm radius of each station collected with hull-mounted ADCP.  An echo sounder (or similar) depth measurement is required at each buoy location.

Pre-cruise planning meeting: Teleconference

Will send CD of DART deployment
