  2. AN NSF-MREFC INITIATIVE SHOULD: - provide exceptional opportunities for cutting-edge research & education; - have a transformative impact on the field; - address high priority community needs; - be technically feasible, with potential risks addressed; - be at a high state of readiness; - be cost effective; and, - establish interagency and international partnerships for development and operations; and - be accessible to the broad user community.

  3. THE OCEAN OBSERVATORY INITIATIVE (OOI) THE VISION To launch a new era of scientific discovery, quantitative assessment, and public engagement focused on REAL-TIME DIRECT OBSERVATION AND MEASUREMENT of a CRITICAL SUBSET of the dynamic processes controlling conditions within the OCEAN BASINS and on the continents.

  4. THE OCEAN OBSERVATORY INITIATIVE (OOI) THE VISION To launch a new era of scientific discovery, quantitative assessment, and public engagement focused on REAL-TIME DIRECT OBSERVATION AND MEASUREMENT of a CRITICAL SUBSET of the dynamic processes controlling conditions within the OCEAN BASINS and on the continents. • THE PATH We will construct a first-generation, networked infrastructure, spanning the western hemisphere, linking fixed and mobile robotic-sensor arrays, with differing levels of power and bandwidth. This system is designed to enable sustained, integrative, and in situ documentation of selected processes and transient energetic events that are beyond the reach of conventional oceanographic investigations.

  5. Project Organizing Principles • Observatory is infrastructure to support: • Independent Measurement Programs & Observation Campaigns • Initial operating capacity supports “Core” instrumentation • All data are semantically available to science community • In near real-time, for perpetuity, while ensuring national security • Infrastructure must be: • Secure, Scalable, Available, Reliable & Transparent • Integration effort to assemble a system of systems • Based on quality & sophistication of existing technology solutions • All infrastructure components will be replaced multiple times • Over life cycle of 30-year Science Program • Project time & budget constrained—Functional scope flexible • Designed to support macro & micro re-scoping • Based on actual development performance

  6. OOI-CI IO PRESENTATION Science Activity Model

  7. Network & Computing Topology Instrument Platforms - Fixed & Mobile Assets, Data Rates 101 to 1010 bps Marine Networks - Acoustic to Optical Media, Continuous & Delayed Connectivity Terrestrial Networks - Routed & Switched Optical across National Backbone Computing Platforms - Low Power Micros, Local Clusters to National Grid OOI Net

  8. Sensitivity to ocean acidification resulting from CO2 uptake, showing global centers of action and largest coastal impact where the OOI networks are. Aragonite depth horizon forecast under CO2 increase scenario. This measures the future INABILITY of organisms to form calcium shells/skeletons

  9. Climate forcing of zooplankton (processes not understood due to lack of sustained observations) Concentration of calanus finmarchicus, the dominant zooplankton species of N.Atlantic Correlation of calanus and NAO NOA with center of action south of Greenland

  10. The seafloor underneath the ocean is a dynamic environment of volcano-tectonic activity coupled to the ocean interior. It hosts many unique ecosystems, it is a source of chemical fluxes into the ocean, and acts as a sink for other material. Direct influence of upper ocean variability in water properties modulated by slow 3-D circulation. Hot, salty waters, methane, CO2 release. Downward propagating internal waves Active geothermal forcing Vent ecosystem
