AR19 Geyer "USRS"


RV Neil Armstrong

Cruise Party

W. Geyer: Chief Scientist, Principal Investigator
Woods Hole Oceanographic Institution Bigelow 208, MS#11 Woods Hole, Ma. USA 02543
+1 508 289 2868

Departure: Jun 24, 2017

Woods Hole

Arrival: Jun 30, 2017

Woods Hole

Operations Area

Eastern Long Island Sound
Lat/Lon: 41° 15.6′ N / 70° 20.9′ W
Depth Range: 6 m / 35 m
Will the vessel be operating within 200 NM of a foreign country? n/a
Are visas or special travel documents required? no

Science Objectives

Autonomous underwater vehicle operations to resolve the spatial structure of fronts and other hydrodynamic features in the estuary and plume of the Connecticut River

SSSG Note: As described in the pre-cruise meeting, this work is being done in a difficult area to work in, (due to currents and fronts), with a major goal being to get the AUV's to work together. Basically, improve AUV ops.  rsl

Science Activities

Deployment of autonomous vehicles near the mouth of the Connecticut River (daytime ops)
Hydrographic measurements (CTD) in Long Island Sound near the mouth of the Connecticut River
Sediment coring in Long Island Sound near the mouth of the Connecticut River (night-time ops).

Additional Information

Is night time work anticipated on this cruise?yesSpecialized tech support (Seabeam, coring, other):
Techs will supply basic on/off for mulitbeam, science must supply waypoints.  Science must supply watchstanders if they wish for supervised data collection.Other required equipment and special needs:
Science will NOT be using the ships micromodem.

"Shipyard" for all REMUS repairs is the Armstrong.  (both the 100's and the 600)  Depending on how far a vehicle has to be disasembled, there might be security issues.  Might need to cover any nearby cameras.  REMUS group has a procedure for this, should not be a problem.

Remus 600will be launched fromarmstong.

Science has requested the mess deck for big meetings, they wish to use the tv as a monitor.  Science realizes that this has to be outside of meal and cleanup hours.   Meetings likely to be 1900, should be OK, need to check with ship to confirm.
Science is NOT using our USBL tracking system.  Our system is not good for shallow watet, also cannot deploy pole in depths expected.

Tracking is from barge. (See attachement for more detail on small vessel operations)

9 surface vessals  keep track?  AIS recomended for all.  This issue still need lots of work.

Numerous small boat ops and transfers, (See attachement for more detail on small vessel operations)

Up to 4 REMUS 100's and 1 REMUS 600 in the water at the same time. 

5/22: No Van Veen core. Science party will bring small a small HAPS corer-- about 300 #.
No logger.  The little corer will be used for the 20 stations near mouth of CT river.
5/22: waiting for specs on science vans

How to keep track of all the people moving around.  (some sort of gangway sign in?)

logistics of science personel not staying on board.
