4 Global sites
3 Regional cabled sites in the NE Pacific
2 Coastal arrays: Mid-Atlantic Pioneer Array, PNW Endurance Array
Each scale incorporates mobile assets
Cyberinfrastructure: enables adaptive sampling, custom observatory view, collaborative analysis
Interfaces for education users
OOI has two fundamental scientific and research mandates that underpin its construction:
We address those mandates by meeting the science requirements during construction, and by building in the most cost-effective approaches to operating the infrastructure.
The most cost-effective approaches include:
Under pressure from NSF and OMB to show improvements in progress within next 6 months
Four areas were the primary focal points for action
External specialists have been guiding a replan of the OOI schedule during the implementation of the Corrective Action Plan
Will be complete late March/early April and will become the new ‘baseline’ for the OOI

Institutionally-Designed Platforms, Coastal Moorings
In Shore Test Mooring 2 (ISTM2): March 2011 – July 2011
At the Endurance Array site, surface wave heights that are large fractions of water depth are a large design challenge.
Testing: Mooring and buoy design for 25 m site.

Institutionally-Designed Platforms, Global Moorings
At Sea Test 2 (AST2): Sept 2011 – April 2012
At the Pioneer Array site
Coastal Surface Mooring (CSM)
Coastal Profiler Mooring (CPM)
will be tested in 500 m of water.
At Sea Test 2 (AST2): September 2011 – April 2012
Seaward of the Pioneer Array site,
a global hybrid profiler mooring
to be tested in 2,500 m of water.
Concerns about global surface profiler and operations with compound mooring deployment/recovery to be addressed.

Approximately half of the Regional System technical designs are on scheduleare under the Firm Fixed Price (FFP) contract with L3-MariPro. Other items are within the schedule float and should not delay any deployments.
The non-L3 major infrastructure pieces of the cable system have been specified and contracted

A half-scale model of a potential frame design is lowered off the R/V Thompson for a one-year deployment at Southern Hydrate Ridge using Medea and Jason. The frame is also being tested to see how different materials react to biofouling during long-duration deployments.
