Ship

R/V Knorr

Cruise Party

Charles Langmuir: Chief Scientist, Principal Investigator Harvard University 20 Oxford Street Cambridge , MA USA 02138 +1 617 384 9948

Departure: May 7, 2012
Bermuda
Arrival: Jun 11, 2012
Punta Delgada, Azores
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 Objectives
Our 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 Activities
The 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.

Scientific Instrumentation for R/V Knorr

Other Science Vans:

Shipboard Equipment
Bathymetry System 12 kHz
Bathymetry System 3.5 kHz
12 kHz Pinger for Wire Use
Multibeam
Fume Hood
Shipboard Communication
Is there a need to transfer data to shore on a regular basis?
Is there a need to receive data from shore on a regular basis?
Is there an expectation to use Skype or any other real-time video conference program?
Basic Internet access via HiSeasNet
Critical CTD Sensors
we need access to 18 megohm water
Sediment Sampling
Rock dredges
Gravity corers
Storage Notes: A Single 20' ft cargo container was loaded aboard the Knorr's 0-1 deck with several pallets holding wax corer and a rock dredge were places beside it on the 0-1. WHOI's Jim Broda was on hand in the Chief Scientist's sted for the loading. All loadinig took place at WHOI, prior to the Van Mooy cruise. Items kept in the storage container / 0-1 deck for the Van Mooy Cruise and repacked/stowed for the Bidle cruise.
Navigation
Will you be using Long Base Line (LBL) navigation?	no
How many nets?	null
How many tansponders?	null
Will you be using Doppler/GPS navigation?	no
Navigation

Navigation Notes:
Winches
Trawl 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 application
Hydro 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.
Standard Oceanographic Cables

Additional Information

Is night time work anticipated on this cruise?yesSpecialized 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.Other required equipment and special needs:
