Departure: Bermuda on May 9, 2012
Arrival: Punta Delgada, Azores on Jun 10, 2012
Mobilization Date: May 8, 2012
Demobilization Date: Jun 11, 2012
Operations Area: Mid-Atlantic ridge between the Kane fracture zone and the Azores
Lat/Lon: 29° 0.0′ N / 44° 0.0′ W
Depth Range: 1500 / 4500
Will the vessel be operating within 200 NM of a foreign country? Portugal (Azores Islands)
Are visas or special travel documents required? no
Science objectivesOur aim is to sample diverse segments of the mid-Atlantic ridge, largely between the Kane and Atlantis fracture zones, exploring the differences in the type and chemical compositions of rock collected from symmetirc segments as compared so assymmetric segments, where detachment faulting is taking place.
Science ActivitiesThe activities will be largely rock sampling, both with dredging and "rock coring". The rock coring takes place using the hydrowinch. Dredging with the trawl winch. We also want to take some gravity cores in the rift valley.THere will also be some multi-beam mapping. This will always be important for sample location and documentation, but there will also be some short surveys where previous data are lacking. Three days of survey time were proposed in the proposal.
Pre-cruise planning meeting: Visit WHOIBoston and WHOI are close. Face to face is always better. But we can teleconference if logistics require.

Shipboard EquipmentBathymetry System 12 kHz
Bathymetry System 3.5 kHz
12 kHz Pinger for Wire Use
Shipboard CommunicationBasic Internet access via HiSeasNet
Is there a need to receive data from shore on a regular basis?
Is there a need to transfer data to shore on a regular basis?
Is there an expectation to use Skype or any other real-time video conference program?
Critical CTD Sensors: we need access to 18 megohm water
Sediment SamplingRock dredges
Will you be using Long Base Line (LBL) navigation? no
Will you be using Doppler/GPS navigation? no
WinchesTrawl Winch with 9/16th trawl wire
Hydro Winch with .25" hydro wire
Winch Notes: There will be very heavy winch use on this cruise. Having sufficient wire and winches in good operating condition is essential.
Wire use and applicationHydro Winch with .25" hydro wire
Trawl Winch with 9/16th trawl wire
Wire Notes: wire speed is a critical factor for the cruise objectives. Hydrowinch speeds of 110m/min are optimal for rock core deployments.

Additional Cruise Items/Activities
|Explosive Devices: no|
Portable Air Compressors: no
Flammable Gases: no
Small Boat Operations: no|
SCUBA Diving Operations: no
Will hazardous material be utilized? no

Specialized tech support (Seabeam, coring, other): We will need to be able to process multibeam data rapidly during the cruise. There will also be 24 hour per day sampling operations, and a rather inexperienced science party, so deck tech support will be crucial.
