Langmuir KN207-02

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

Shipboard Equipment

Bathymetry System 12 kHz
Bathymetry System 3.5 kHz
Multibeam
Fume Hood
12 kHz Pinger for Wire Use

Shipboard Communication

Basic 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 Sampling

Gravity corers
Rock dredges
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

GPS
Navigation Notes:

Winches

Hydro Winch with .25" hydro wire
Trawl Winch with 9/16th trawl 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

Slip ring required? no Number of conductors: 
Non-standard wire required? no Type: 
Traction winch required? no Describe: 

Specialized Deck Equipment

Mooring Deployment/Recovery Equipment Required: no Type: 
Cruise Specific Science Winch Required: no Type: 
Nets Required: no Type: 

Over the Side Equipment

Will you be bringing any equipment (winches, blocks, etc.) that lowers instruments over the side? yes
Details:
WHOI Provided Rock Corer/Wax corers in addition to a rock dredge.

Special Requirements

Elecrical Power: yes Identify: we need clearn power for the direct current plasma spectrometer
Equipment Handling: no Identify: 
Inter/intraship Communications: yes Identify: Pi Javier Escartin will be in France. We need to be able to send multibeam data and skype.
Science Stowage: yes Identify: We will need to store 60-80 dredges
Water: yes Identify: Clean DI water essential for chemical work

Additional Cruise Items/Activities

Explosive Devices:no
Portable Air Compressors:no
Flammable Gases:no
Small Boat Operations:no
SCUBA Diving Operations:no

Hazardous Material

Will hazardous material be utilized?no
Describe deployment method and quantity:

Radioactive Material

Radioiosotopes:no

Additional Information

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