OOI Construction and Data Status Update: July 19, 2015

The OOINet Build 5.1 integrated solution is working, pulling data through the uFrame software for visualization in the user interface, with Alpha I Testing completed on June 21. Alpha testing consisted of 28 testers including operations, science and management users from within the project, UNOLS OOSC, and NSF. We received 206 discreet comments which were functionally categorized and prioritized for inclusion in the follow on software builds. Build 5.2 is being integrated and will address a significant number of the Alpha I comments. Alpha II testing will be conducted by the same Alpha I testers so that we can gauge the incremental improvements. We are finalizing the number of participants for the Beta Test, and in early August will identify a process for external users to volunteer for testing. Pre-commissioned data will be released as OOINet functionality improves, which we expect to occur with the completion of Build 6. Below is the proposed construction completion schedule.

Key Construction Milestones:

  1. August 5 – OOINet Build 5.2 integration and testing complete.  Alpha II testing (internal) begins.
  2. Aug 28 – OOINet Build 6 integration and testing complete. Load and Beta testing begins. (Beta testers include existing Alpha testers, and a number of science community members. Criteria for selection of Beta testers will be released upon completion of Alpha II Test)
  3. Sep 25 – OOINet Build 7 integration and testing complete. Final User testing begins.
  4. Oct 7 – Announcement of Commissioned System

We continue to provide interim delivery of the Cabled Array seismometer and bottom pressure data through IRIS http://www.iris.edu/hq/. Delivery of Cabled Array tilt meter and co-located temperature plots continue through Dr. Bill Chadwick’s website at http://www.pmel.noaa.gov/eoi/rsn/ .

The Pioneer Array will complete construction deployment in the coming week with deployment of two uncabled Coastal Surface Piercing Profilers and three gliders. We continue to evaluate the maturity of the AUV Dock and fuel cells for further development and inclusion during construction, and will make final determinations prior to the next maintenance cruise in October 2015. The Endurance Array has completed all construction deployments.

The Cabled Array is currently at sea completing its final construction with the installation of three Deep Profilers. They are also conducting their scheduled annual maintenance cruise turning profilers and instruments. As part of the cruise bathymetry work, they have identified what they believe to be the site of the Axial eruption in April 2015. In the next leg of the cruise, time permitting, they will conduct one ROV dive to the site. Bathymetric survey data and photos are now available through the MGDC web portal.

Upcoming maintenance cruises include:

  • Irminger Sea – August 2015
  • Pioneer – October 2015
  • Endurance – October 2015
  • Argentine Basin – November 2015
  • 55S Southern Ocean – December 2015

The HelpDesk is online and available to help answer questions during this pre-commissioning period.
