  1. Sustaining Observations for Decades with the OOI

  2. OOI Science Requires Resolution of High Frequency Forcing (minutes-hours) In Distant and/or Extreme Environments for Sustained Periods (years-decades) Four Global high latitude sites Station Papa Irminger Sea Argentine Basin Southern Ocean Two Coastal Arrays Endurance Array Pioneer Array Cabled Array Meso-scale, Plate Scale network The locations and type of infrastructure drive engineering design, deployment, and maintenance profiles

  3. OOI Overarching Objectives • The design requirements of the OOI lead to three essential objectives: • Sustain, for decades, the delivery of multiple streams of ocean data, resolving ocean processes and properties across a range of temporal and spatial scales; • Facilitate the use of the designed capabilities of the OOI for specific at-sea experiments or extension of the temporal and spatial reach of ocean research; • Sustain the expansion capabilities of the observatory as technology evolves and in response to new science questions. 1

  4. OOI is a community facility OOI currently is an Major Research Equipment Facilities Construction (MREFC) project, funded by NSF, approximately 75% through the 66-month construction phase. Operations phase formally begins in March 2015 The bulk of the deployments occur in 2014 and early 2015, with gradual transition to the formal shift to operations in March 2015. Performance data under operational conditions will be obtained in 2015 and beyond. OOI data policy is “open access” Efficiencies in operations and maintenance procedures are still being developed in order to minimize long-term operational costs.

  5. Deployed Scope of OOI (over 750 instruments distributed over all moorings, benthic packages, seafloor nodes, gliders and AUVs) Global Arrays Extensive details about each component can be found on the OOI website (http://oceanobservatories.org)

  6. Deployed Scope of OOI (over 750 instruments distributed over all moorings, benthic packages, seafloor nodes, gliders and AUVs) Coastal Arrays 2 20 Extensive details about each component can be found on the OOI website (http://oceanobservatories.org)

  7. Deployed Scope of OOI (over 750 instruments distributed over all moorings, benthic packages, seafloor nodes, gliders and AUVs) Cabled Arrays Connected by 880km of seafloor cable, with 10KW power, internet connectivity between 7 primary nodes, multiple secondary nodes, and all distributed instrumentation Extensive details about each component can be found on the OOI website (http://oceanobservatories.org)

  8. Overall OOI Global construction status Global Station Papa – deployed in July 2013. 2 flanking moorings, one hybrid profiling mooring, 3 gliders. Irminger Sea – to be deployed September 2014 55o South – to be deployed January 2015 Argentine Basin – to be deployed February 2015

  9. Construction to Operations – 2015 and beyond Global Arrays on a 12-month maintenance cycle, fixed and mobile assets (recover, redeploy replacement) Coastal Arrays (most elements) on a 6-month maintenance cycle (recover, redeploy replacement) Cabled assets on a 12-month maintenance cycle (not all assets recovered annually) Coastal gliders will be rotated every 2-3 months – initially These requirements lead to a steady rhythm during operations

  10. Sustaining the configuration of the OOI • Initial deployment configurations lead to ‘default’ configuration at Commissioning, after user feedback in the ‘pre-commissioning evaluation’ of the OOI • OOI team sustains the configuration until directed otherwise through approved work (NSF proposals) • Misconception: OOI operations team will adjust the observatory to suit its own science agenda • Reality: strict configuration control, OOI team only implements approved configurations

  11. Communicating Capabilities and Opportunities Upcoming webinars March 2014: Station Papa – assessing the first nine months April 2014: Instrumenting the seafloor – the initial configuration May 2014: Irminger Sea – deployment and sampling plan Town Hall at Ocean Sciences – Feb 2014 Workshops (in planning stages) Fall 2014: The NorthEast Pacific: an oceanographic laboratory with extensive observatory elements (OOI, Ocean Networks Canada, PMEL) Fall 2014: Temporal resolution of coastal dynamics and ecosystem responses using OOI assets

  12. Access to pre-commissioned data Pre-commissioned data will be available via the OOI website following post-deployment validation testing Per the OOI Data Policy, there will be open access to all data Users will find a ’Data' tab on the OOI website that will serve as the data portal or entry point

  18. Instrument status at Station Papa HYPM: 4 instruments on the float 1 SBE below the sphere (2) WFP with 4 instruments each We are getting data from the 8 on the WFPs Each flanking moorings has 16 instruments: 4 instruments on the top sphere 1instruments on the lower sphere 11 SBEs on the wire we know the FLORT on MFM-A died; we lost contact with all of MFM-A- we are receiving data from MFM-B = total of 16 instruments Gliders- 3 with three instruments each = 9 instruments; getting data from 2of them TOTAL INSTRUMENTS = 13 + 32 + 9 = 54 DEPLOYED GETTING TELEMETRY DATA FROM = 8 + 16 + 6 = 30 (56%) MAY BE ACQUIRING DATA FROM BOTH FLM (except Flort) 50/54= 92% but seriously doubt the GSPP is useful so: 46/54 = 85%

  19. Summary preliminary assessment • GSPP delivered good data while the data were transmitted • After calibrations/adjustments, both WFP are delivering good CTD, 3-D current, oxygen, chlorophyll data, with exception of conductivity of lower profiler which may be unrecoverable. No calibration/validation for backscatter, but signals exist that are correlated with other quantities • After calibrations/adjustments, FLMB is delivering good CTD, ADCP current, oxygen, pH, chlorophyll data. pH somewhat more spiky than expected, need more data. No calibration/validation for CDOM and backscatter. • FLMA is believed to be functioning, the calibrations were all applied. Only FLORT stopped working after deployment. Data downloads worked well from the ship. • Upper WFP profiler sinks to 700m, higher current for upward profile probably results in reduced endurance • Glider download rates are below expected rates – corrective steps are being taken

  20. FLM-B ADCP data Validation either with vessel-mounted ADCP data from cruise, or with low-frequency data from PMEL ADCP in upper layer (requires some research)

  21. FLM-B CTD data Deep salinity signals are same size as accuracy spec

  23. Operating and Maintaining the OOI Execute processes, procedures, work instructions to meet operational requirements and deliver data products, including Marine System status monitoring, reporting and corrective actions Pre-deploy (test and integration), Deploy (platform ops, command/control) Vehicle ops, alarms/alerts, sampling strategies, data QC Recovery, post-recovery (refurb, calibrate), data recovery Performance monitoring and reporting, Asset management, Incident Reporting Cyberinfrastructure Cybersecurity, System monitoring, status display, software maintenance Performance measurement, network and application enhancement Hardware/Software – Development, Maintenance, Quality assessment Maintenance and improvement of data products, algorithms, metadata Data QA/QC enhancements, user request and support

  24. OOI-specific questions Maintenance of high-latitude buoys The OOI is a highly-integrated observatory, with common, integrated construction and refurbishment processes for all systems. Extracting just the high-latitude buoys from the integrated system would have cascading cost consequences across many categories of O&M. Similarly, the science themes addressed by the OOI infrastructure rely upon the elements of the integrated observatory, and are not easily partitioned on the basis of Site A or buoy B. 109 UNOLS shipdays (global class vessels) are expected to be required for maintenance of the 4 Global Sites in 2016 (and each subsequent year)

  25. Proposing to use the OOI From the NSF Division of Ocean Sciences newsletter (11/30/12) NSF is encouraging interested individuals and groups to propose and participate in science workshops centered around different components of OOI (see the Pioneer Array workshop report as an example). Individuals/groups interested in submitting research proposals to NSF should contact their programs officer(s) for information about the timing and process.

  26. Proposing to enhance / extend the OOI From the NSF Division of Ocean Sciences newsletter (11/30/12) In 2014, NSF expects the project to achieve certain milestones that will allow NSF to communicate a process to the community for proposals that add instruments or infrastructure to the current OOI configuration.

  27. General questions Support of curiosity-driven research Proposals for external research must be processed and approved by NSF. The OOI project, under the terms of the award between Ocean Leadership and NSF, plays no role in the processing or approval of external research, regardless of its potential alignment with the overarching science themes of the observatory.

  28. OOI-specific questions How will proposals be handled? Proposals to use OOI data or to alter/expand the OOI infrastructure must be submitted to the appropriate core research program within the Division of Ocean Sciences at NSF. At this time, no special observatory panels have been discussed. A UNOLS subcommittee, the Ocean Observatory Science Committee (OOSC), will serve as a resource to NSF, just as other UNOLS subcommittees assist with deep submergence, icebreaker platforms, and scheduling. The OOI project will provide technical guidance to proposers, and will offer periodic engineering ‘bench-top’ worksessions for proposers, but will play no role in the processing, evaluation, or approval of proposals submitted to NSF or any other agency.

  29. OOI-specific questions What is the process for adding a PI instrument to the OOI? Investigators must submit a proposal to NSF to add an instrument to the OOI infrastructure. The OOI project will provide technical guidance to interested investigators (technical feasibility), and all technical specifications for the interfaces will be freely available. Any NSF-approved new instrumentation will be tested for technical compatibility with the observatory before first deployment. Data flow from such added instrumentation will be subject to the OOI data policy, ‘open access’, as outlined in the OOI documentation. There is an option in the data policy to allow external PIs to request a one-year period of data sequestration from public access for specialized new instrumentation.

  30. OOI-specific questions How will OOI handle technology innovations? Internally, the OOI will address advances in technology on an annual basis through its performance reviews,engineering assessments, and reviews by the external science committee. These incremental (annual) steps toward technical ‘refresh’ will need to be accommodated within the annual operating budget for the observatory. Externally, individual investigators may propose to add/replace a capability of the observatory due to the successful development of a particularly innovative sensor/device. As described previously, such proposals have a clear path for preparation: first with technical consultation with OOI engineers about power, connectivity, data flow, etc., followed by the normal NSF proposal submission process. The OOI project has no role in the evaluation and approval of such proposals, and only provides guidance on the technical feasibility of the innovation.
