2017 AUV Sentry Jefferson Cruise

Andrew Bowen, Woods Hole Oceanographic Institution


WHOI operates the NDSF, which includes the human-occupied Deep Submergence Vehicle (HOV) Alvin, Remotely Operated Vehicle (ROV) Jason and the Autonomous Underwater Vehicle (AUV) Sentry. These facilities are funded by federal agencies such as the National Science Foundation (NSF), the Office of Naval Research (ONR) and National Oceanic & Atmospheric Administration (NOAA) on a daily rate basis, to provide deep sea capabilities for funded science programs sponsored by these agencies. R/V Atlantis served as the support vehicle for HOV Alvin. The ROV and AUV can be installed on other vessels suitable for their deployment. This fly-away capability provides scheduling flexibility to meet a much wider range of requirements for the scientific community.

The AUV Sentry aboard the NOAA Ship Pisces, will be utilized in support of the NOAA funded cruise, to study the eastern continental margin which separates the oceanic crust from the continental crust. The core science objectives of this cruise have yet to be formally announced. Sentry vehicle use will be as directed by BOEM and in accordance with the capabilities discussed in the Sentry User Guide. Sentry will mobe in Morehead City, NC on September 9th and demobe in Morehead City, NC on September 29th. There will be a total of 21 charge days for the vehicle (2 mob, 1 demob, 18 at sea). In addition, the Woods Hole Oceanographic Institution will provide and install one set of USBL cables to run from the NOAA Ship Pisces to the AUV Sentry control van. These cables will be left installed in the NO
