Image of oceanographic equipment platform deployed off the coast of Martha's Vineyard
September 21, 2011

Oceanographic equipment customized to reach the benthic boundary layer

Steaming to the deployment site south of Martha's Vineyard, MA in 2011. The platform shown was specially adapted so the arm cycles up and down through the Benthic Boubdary Layer while deployed on the seafloor.  For more information see https://soundwaves.usgs.gov/2011/11/fieldwork2.html.

USCGC Healy Coming Back to Free Louis

Nice photo-op of Healy with a striking background.

[This set of photos provides selected image of two icebreakers working together in the Arctic Ocean.  All images were taken from aboard the Canadian Coast Guard Ship (CCGS) Louis S. St-Laurent (Louis), from which science crew from the Geological Survey of Canada, Canadian Hydrographic Servie, and a U.S.

USCGC Healy Working at Close Quarters with CCGS Louis S. St-Laurent

It is very unusual for large (400 ft) vessels to be so close together during normal science operations.  In this case, the skilled ship handling of the Captain from USCGC Healy enabled Healy to back within ~75 ft of Louis to clear ice around the bow of Louis, thereby releasing pressure and allowing her to move again. Observers from

USGS scientists test the moving arm bottom platform

USGS scientists test the moving arm bottom platform at the Woods Hole Oceanographic Institution (WHOI) dock.  While it was deployed, the system moved sensors through the bottom boundary layer and transmitted data in real time to shore via WHOI's Martha's Vineyard coastal observatory.

USGS scientists assembling a novel profiling arm

USGS scientists assembling a novel profiling arm to measure suspended sediment in the benthic boundary layer. This large seafloor platform was later deployed for several months off Martha's Vineyard, MA as part of the Optics Acoustics and Stress In Situ (OASIS) Project in 2011.

Multichannel seismic sled being deployed off ship

The airgun sled is painted orange and suspended from the A-frame.  The three airguns are suspended beneath the sled. The multichannel digital streamer (yellow cable going into the water from the sled) is towed from the the weighted sled to keep it under the ice. This photo shows the number of crew required to safely deploy the airgun sled. This photo also shows US Coast

USCGC Healy in Heavy Ice Passing CCGS Louis S. St-Laurent

USCG Healy is circling to pass CCGS Louis in order to break her free from the ice. The joint field program utilized two icebreakers so that the seismic vessel, with gear in the water behind the ship, could be broken free when the ice prevented her forward progress. A ship towing gear has limited maneuverability, so a second ship to do the ice breaking saved hauling (and
