Procedures for Obtaining ROV Dive Data

Procedures: Follow the cruise planning procedures. After the cruise, the scientist must submit a postcruise report for data to be released. In addition, the scientist must submit an external request for data and video tapes to Lonny Lundsten (831-775-1762), MBARI's primary contact for external users of ROV video and data. In the request, the scientist should specify the formats and data types they would like from their expeditions, and if they would like them made available on an ftp site or a CD. After this request is received, data will be placed on MBARI’s anonymous ftp site within a week or two. Copies of dive video will be mailed to the scientist within 30 days of the request date. Data burned onto a CD will be mailed along with the video tapes. Detailed information for each data type and the data policy are below.

Video tapes:Within 30 days of the request date, the scientist will receive by mail one copy of the dive video in the tape format of their choice. The tape formats available are DVD, VHS, MiniDV, Hi8, Sony 1/2" Analog, Sony Digital Betacam™or Panasonic D-5 High Definition. Digital Betacam™, miniDV and D-5 High Definition video frame codes can  be synched with frame grab filenames and camera log data. For other formats it is recommended that the Betacam™ frame code be superimposed on the video images (see example of overlay); please let Lonny know if you want this overlay to be continuous, only at the beginning of each tape, or not at all. The Original Digital Betacam or high-definition video tapes will remain in the MBARI archives.

Camera log: Files of video frame code with corresponding UTC time and camera settings are available via MBARI's anonymous ftp site or CD. These enable comparison of video with UTC time-stamped data sets and calculations of depth of field. 

Video annotations: If the scientist annotates the incoming video while on board the MBARI research vessel, those annotations can be made available on the anonymous ftp site or CD. Please indicate if you would like these annotations. Training in the use of the annotation software should be arranged before the cruise with Lonny. The scientist can request Video Lab Technician time to annotate their videos. A charge of $60/hr will be added for these services. Completion of these annotations will be dependent on the number of dives and the number of tapes per dive, and will be determined at the time of the request.

Frame grabs: Still images taken from the video feed during the cruise are available in the following file types: jpg and png. The filenames correspond with the source video frame code. In your request, please indicate which format you would like to have available on the ftp site or data CD.

  • Filenames like 00_00_00_00.jpg are JPEG versions of the images, converted to PC-friendly filenames. These will be provided by default on the ftp site. View in browser or image processing software on any platform. After viewing JPG images, you can request high resolution PNG versions of specific images.

Navigation data: The UTC time-stamped navigation data acquired by the ROV and ship are processed automatically during ship to shore transfer following the cruise. If requested, they will be available via MBARI's anonymous ftp site or on a CD. 

  • Filenames like nav2001001tibr.txt are comma-delimited ASCII files of navigation data from the vehicle.
  • Filenames like nav2001001wfly.txt are the navigation data from the ship.

CTDO data: The UTC time-stamped conductivity, temperature, depth, and oxygen (CTDO) acquired by the ROV or profiling CTD rosettes are processed automatically during ship to shore transfer. They will be available via MBARI's anonymous ftp site or CD. 

  • Filenames like 2001001tibrCtdDer.txt are comma-delimited ASCII files of CTDO data, with calibrations and algorithms applied and derived values calculated from the raw sensor data. 
  • Filenames like 2001001tibrCtdDer.gif are GIF plots of the same data.
  • Filenames like 2001001cast1.txt are ASCII files of rosette cast data.

Other data: All other, project-specific data are not handled automatically. Contact Martin Suro to access data already logged on the ship (e.g., vehicle status data). Contact Martin Suro to work out strategies for mechanically and electrically integrating new instrumentation with the ROV and logging the resulting data. Depending on the strategy developed for the instrument, the data might be logged directly by the external scientist or downloaded to CD or DVD aboard the ship. This data will not be permanently archived at MBARI and must be archived and processed by the external scientist.

Samples: All samples collected during the cruise shall be the responsibility of the external scientist, and will not be stored in the MBARI Sample Archive (alternate arrangements must be approved by MBARI and specified in writing). Additional information can be found on the MBARI Sample Archive web pages.

Policy: Data, including video, frame grabs, navigation, and CTDO data provided to the chief scientist are protected under MBARI's policy during the scientist’s two-year exclusive-use embargo period. The chief scientist is responsible for providing copies of any of those data to scientific collaborators. Unless an extension is granted by MBARI's President, these data will become available for general use when the two-year embargo expires. Non-MBARI scientists who collect other data and samples retain possession and responsibility for those data and samples. 

Scientists who wish to contract for additional MBARI resources or obtain additional data must submit a separate request to Judith Connor, Director of Information and Technology Dissemination at MBARI. These requests are fulfilled only as resources are available. Alternatively, MBARI researchers may sponsor collaborators and assign a portion of their allocated MBARI resources through a Collaboration Agreement
