RV Neil Armstrong

Cruise Party

Ying-Tsong Lin: Chief Scientist
Organization Name 266 Woods Hole Rd Woods Hole, MA USA 02543
+1 508 289 2329

Albert Plueddemann: Principal Investigator
Woods Hole Oceanographic Institution Clark 202A, MS#29 Woods Hole, Ma. USA 02543
+1 508 289 2789

Departure: Mar 31, 2016

Norfolk, VA

Arrival: Apr 6, 2016

Woods Hole, MA

Operations Area

OOI Pioneer Array, and specific survey transects east of the continental slope
Depth Range: min / max (m)
Will the vessel be operating within 200 NM of a foreign country? no

Science Objectives

  • Acoustic survey of defined transects off the continental slope (NOAA/UNH)
  • Mooring maintenance at the OOI Pioneer Array (WHOI)
  • Deployment of Acoustic Moorings near the Pioneer Array (WHOI)

Evaluation of the R/V Neil Armstrong’s scientific capabilities (Science Verification) by the voluntary participation of groups from NOAA, UNH and WHOI. Written evaluation from the Science Parties will serve as a guide to future procedure and design modification in the continued operation of the ship in oceanographic service.


The R/V Neil Armstrong is a new vessel, and it’s capabilities for science have not been fully tested. The objective of this cruise is to test and evaluate the ship. While WHOI wants to see all participants gain usable data and/or samples from our Science Verification Cruises, science personnel must understand that the ship and her systems may not function as intended.

Acoustic Mooring Deployment
Deploy a couple of moorings consisting of hydrophone vertical line arrays, physical oceanography sensors, steer spheres, glass floats, acoustic releases and anchors.  I would also like to hang an acoustic source on the side of the vessel to transmit sounds to the moorings.

Acoustic Survey, Contental Shelf
The United States has been collected data in support of the establishment of an Extended Continental Shelf (ECS) in regions surrounding the U.S. and its territories since 2003. Included in these efforts have been 5 cruises off the east coast of the US that have resulted in a remarkable, nearly complete high-resolution multibeam bathymetry coverage of the margin beyond the shelf-break (see attached figure). As these data are analyzed and as the Commission on the Limits of the Continental Shelf makes recommendations to other nations, we have concluded that the case that the U.S .could make for a submission could be strengthened by several strategically located concurrent MBES and high-resolution 3.5 kHz profiles run orthogonal to the margin. Such lines could easily fit on an ARMSTRONG science verification cruise offering an opportunity to test the high-resolution subbottom profiler and the multibeam sonar in real-data collection scenarios.
