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. | |
Additional Info | |
| Pre-cruise Planning Meeting: Teleconference/Visit WHOI | |
| Meeting Notes: Stanton is at WHOI and can participate in person, Gauss is at NRL and will participate by telecon | |

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. 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) | |||||||||||

| 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 umbilical cable deployment box 6.5 ft x 4 ft x 3 ft | |||||||||||

| 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. | |||||||||||
