Departure: Sep 6, 2011

WHOI

Arrival: Sep 17, 2011

WHOI

Operations Area

Northern Flank of Georges Bank
Lat/Lon: 41° 0.0′ N / 66° 0.0′ W
Depth Range: 50. m / 350. m
Will the vessel be operating within 200 NM of a foreign country? Yes, Canadian Waters/Hague Line (>10nm from Hague Line)
Are visas or special travel documents required? no

Science Objectives

Conduct acoustic and net surveys over and near Georges Bank. Advanced broadband acoustic systems will be used to classify swimbladder-bearing fish through their resonance. The studies will involve transects and measurements at fixed locations.

Science Activities

Deploy EdgeTech sonar and NRL source and receiver systems over Georges 

Bank studying the fish in conjunction with FR/V DELAWARE II.  Ship's personnel 

required for deployment and recovery of instrumentation: Bo'sun and 1 to 2 

seamen.

Storage Notes:

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: Reguire the most accurate position information available on ship.  Is that your Doppler/GPS system?  Selecting Doppler/GPS not available as selection choice in questionaire.
Box:  41.0N-43.75N and 66.0-76.75W

Winches

CTD Winch with .322" Electro-mechanical wire
Other Portable Winch
Winch Notes:

Stanton group will be bringing a winch either from URI's scanfish system or a WHOI 'winch pool' winch with a wire for towing WHOI EdgeTech system off the stern Aframe.
Gauss (NRL) group will bring a winch and wire for towing their source off the stern Aframe.

NRL winch 8 ft. x 8ft. x 8ft. 10000 lbs. - main deck

'ScanFish' (or other) winch 5 ft. x 5 ft. x 4 ft. 2500 lbs. 01 level (01 is where WHOI put it on Endeavor)

Wire use and application

CTD Winch with .322" Electro-mechanical wire
Wires Notes: Gauss group uses CTD wire (as strength member and for telemetry data)  off the starboard side for towing receiver array

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: yes Type: see notes
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:

Two systems being used in sequence; NRL system and WHOI Edgetech system.

On Endeavor Edgetech system has been moved to port rail using a pallet jack during NRL system operations. WHOI Edgetech is deployed using scanfish winch on 01 deck through A-frame

 

NRL system is a two wire deployment; source through center of A-Frame using NRL supplied block and NRL winch on main deck and the receiver array deployed/retrieved from starboard J-frame using CTD wire as strength member while underway(avoids interference with prop).  Three Air tuggers available to assist in deploying/recovery of source, which includes chain weight. 

 

Deck space needs:

NRL source and deployment box 14 ft. x 2ft. x 2 ft. 1800 lbs - main deck

NRL Winch 8 ft x 8 ft x 8 ft @ 10000lbs – main deck
NRL receiver 30 ft x 1/4 ft - main deck starboard side

NRL receiver umbilical cable deployment box 6.5 ft x 4 ft x 3 ft
WHOI EdgeTech sonar 5 ft. x 4 ft. x 2 ft. 400 lbs. - main deck

Special Requirements

Elecrical Power: yes Identify: 480V 3 phase 30 Amp for NRL winch main deck; 480V 3 phase 30&60 Amp circuits for two Power Amplifie
Equipment Handling: no Identify: 
Inter/intraship Communications: yes Identify: Radio communication for marine mammal observers and ship communication to NOAA ship Delaware
Science Stowage: no Identify: 
Water: no Identify: 

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?yes
Describe deployment method and quantity:
Receiver array is filled with ISOPAR-M oil (~20 gallons). 

Radioactive Material

Additional Information

Is night time work anticipated on this cruise?yes
Specialized tech support (Seabeam, coring, other):
Is night time work anticipated on this cruise? yes

Specialized tech support (Seabeam, coring, other): The two groups generally split the day in two with each group working roughly 9AM-9PM or 9PM-9AM.
Nighttime ops usually begin after dinnertime and run continuously until just after breakfast.
Daytime ops may involve more deployments and recoveries than just once per day.
Need XBT launcher and computer, NRL will provide XBTs
Other required equipment and special needs: Mobilization begins Sept 2 and continues through Labor Day weekend

Source system was used extensively on R/V Oceanus during a 2007 cruise.  John Dyke was our POC for that cruise.
Other required equipment and special needs:
Up to three air tuggers need to be available for NRL deployment  and recovery of NRL systems.
