Operations Area

North Atlantic
Lat/Lon: 37° 26.0′ N / 50° 4.0′ W
Depth Range: 2435 m / 5374 m
Will the vessel be operating within 200 NM of a foreign country? no

Science Objectives

Annual maintenance of the two North Atlantic DART buoys.

Science Activities

Recover Bottom Pressure Recorder (BPR) at each station and redeployed new BPR. At station 44402, located 135 nm SE of Fire island, NY the surafce buoy will be brought on deck, the mooring secured, buoy serviced and redeployed. At station 44401, located 790 nm NE of Bermuda, the buoy and mooring will be replaced.

Hazardous Material

Will hazardous material be utilized?no

Additional Information

Is night time work anticipated on this cruise?yes
Specialized tech support (Seabeam, coring, other):
Other required equipment and special needs:
Before sailing it was noted that these moorings do not have acousitcal reseases.  Method of recovery and deployement was discussed and a plan thought out. 
During the swap over of the 4401 (deep ocean) mooring, once buoy is on deck, moring techs will disconnect wire cable and add a surface sphere floatation buoy to hold and mark the location of the wire during matenance.  Once new surface buoy is ready to be deployed, Oceanus will recover the small buoy and bring the 4000m+ wire end on board to connect to new NOAA buoy.  Then deploy over starboard side of vessel.
