Alvin Frame-Grabber
The Frame-Grabber imaging system mounted on the submersible Alvin provides Web access to video imagery co-registered with vehicle navigation and attitude data for shipboard analysis, planning deep-submergence research cruises, and review of data following research expeditions
Jason Virtual Van
The Jason Virtual Control Van is a real-time logging system that provides functionality similar to the Alvin Frame Grabber. It is also equipped with an event logging system that is used to digitally log comments and observations during operations. The Virtual Van interface can also be accessed, and events can be logged, via a web browser running on the ship's network
Sentry Data
Precise navigation, robust control and co-registered sensors permit Sentry to characterize the seafloor and the near-bottom environment on the meter-scale through complementary sensing modes

Logging & Display
Examples of NDSF at-sea data collection subsystems, including DVLNav, Frame-Grabber, Virtual Van, and Fledermaus
Archive Policy
Woods Hole Oceanographic Institution (WHOI) maintains an archival system for oceanographic data and samples that have been obtained using the vehicles and sensors of the National Deep Submergence Facility (NDSF). This policy describes the treatment of these data.
Data Acquisition
Each NDSF vehicle embodies a different basis of design, a different history, and operates with its own characteristic behavior. Consequently, each vehicle offers a different sensor package and data collection strength.
Data Deliverables
Standard data packages have been defined for each vehicle so that users can more effectively plan their sensor requirements and personnel needs
Lat/Lon X/Y Converter
