Briefing on the Integrated Ocean Observing System (IOOS) and the Data Management and Communication System Steven Worley NCAR 19 August 2005 Objectives • What is IOOS? • What is DMAC? • How might OHH participate?
The Integrated Ocean Observing System (IOOS)Oceans & Coasts Component of the U.S. Integrated Earth Observation System (IEOS) & the International GEOSS An Interagency Collaborationfor the Public Good NOAA Navy NASA NSF USACE USGS MMS EPA USCG DOE http://www.ocean.us
IOOS GoalsIntegration for Broad Benefit • Detect and Predict Change • Mitigate effects of natural hazards • Improve safety and efficiency of marine ops • Improve national security • Reduce public health risks • Protect and restore marine ecosystems • Sustain marine resources Society oriented goals
E.G. Florida Fish and Wildlife Research InstituteRed tides off southwest Florida, Aug. 17 Reported system effects: • Expanding area since last week • Benthic mortalities • Fish kills • Discolored water • Turtle mortalities • Human respiratory irritation http://www.floridamarine.org/
E.G. Florida Fish and Wildlife Research InstituteRed tides off southwest Florida, Aug. 17 Actions: • Airplane over flights – not good weather – more flights needed • Ocean sampling cruise 10-12 August
E.G. Florida Fish and Wildlife Research InstituteRed tides off southwest Florida, Aug. 17 Observation and what ifs? • Respiratory irritation greater with westerly wind • What if Hi-res wind predictions were available? • What if satellite sensed data, not impacted by weather, was easily used? • What if real-time ocean circulation models were run to analyze and predict? • What if ocean models with T, O2, nutrients, red tide samples, were easy to run? Contention: We have the ability to do these estimates IOOS strives to enable them and address the goals previously shown
The Political Environment • Commission on Ocean Policy • Report • Executive Order • Ocean Action Plan • Legislation • Senate (S. 361 - recently passed) • House (H.R. 1489, 1584)
IOOSTwo Interdependent Components Global Ocean Component Coastal Ocean Component Regional Coastal Observing Systems National Backbone
IOOS Coastal Ocean Component • National Backbone • Largely federal • Satellite remote sensing • Reference, fixed-site stations • Links to global component • Fewer variables • Regional Coastal Systems • Largely non-federal (may be • federally funded) • Regional priorities & needs • Greater resolution • More variables Both use IOOS data standards and exchange protocols
The Global ComponentAn International Collaboration IOOS is the U.S. contribution to international GOOSand the Oceans & Coasts component of IEOS & GEOSS
IOOS Three Subsystems • Measurements • Remote and in situ observations • Telemetry • Data Management and Communications (DMAC) • Integration • Data analysis and modeling • Data synthesis, evaluation • Change detection and prediction
IOOS Education Component • Ocean.US Education Workshop, 22-24 March 2004, Charleston, SC • Result: Workshop Report • Promoting Lifelong Ocean Education: Using the Integrated Ocean Observing System (IOOS) to Shape Tomorrow’s Earth Stewards and Science and Technology Work Force. • Muriel Cole Ocean.US liaison to OHH • Hear more at IOOS Human Health Workshop, January 2006
DMAC is the component that enables the diverse sources of data to be accessed in a consistent manner. DMAC is composed of data standards, communications protocols, software tools, archiving and community agreements.
Why so much focus on DMAC? • DMAC is the “I” in IOOS Why is DMAC the top priority? • The weak link in the chain • Huge payoff from investment
Data Supplier Data User Multi-beam Geo-chemical Satellite DMAC Three Guiding Principles Existing Protocol DMAC • Do no harm • Expand access Data Suppliers • Increase efficiency
The DMAC Plan is a framework for interoperability among independent, heterogeneous systems, large and small • Organizations will manage their data independently • Standards – enable interoperability • Data discovery and delivery to applications • New - “Web services” standards • communication between applications • E.g. Browsers that initiate Google searches
The heart of integration isStandardsExample:Surface Marine Buoys • “Work horse” for coastal and open ocean observations • International, National and Regional use • Surface , near-surface and subsurface observations
What “Simple Standards” buy you today… • Meeting present “standards” • A “ticket” onto GTS • Real-time provides utility for national forecasts & warnings operations • “Accepted” QA /QC • Immediate payoffs • Large user base • Improved local storm detection, intensity and track forecasts • Beach rip tide, boating safety and trip planning, & others
But today’s standards are too narrow. Inefficiencies and lost opportunities … • E.g. Delayed mode not standardized • Data not uniformly • archived • QCed • Data not uniformly available for • climate assessment • commercial applications • research (esp. interdisciplinary) • Commonalities are not exploited (e.g. a time series) • Variables: winds, waves, temperature, salinity, biota, chemicals, fish landings • Platforms: surface marine buoys, terrestrial stream gauges, tide gauges • Products: forecasts, satellite products, coral bleaching (paleo), El Nino index

The DMAC Plan – a community effort • Brought together • 6 Federal agencies • 6 Universities • 4 Regional/State agencies • 3 Private sector orgs. • Steering Committee,2 Outreach Teams,4 Expert Teams • Data Facilities Outreach • User Outreach • Data Discovery & Metadata • Data Transport • Data Archive & Access • Applications & Products
The DMAC Plan – a community effort • Four levels of review • Selected specialists • Public workshop • Two public reviews • 150 reviewers • 6 Federal Agencies • 22 Universities & Institutes • 13 Private Sector • 13 Regional/State agencies • 5 International • Presented at numerous meetings • ASLO • AGU • AMS • JCOMM, WMO • IODE
The DMAC Plan – What does it contain? • Articulates the vision, requirements,and technological approaches. • Recommends next steps, estimates costs and timeframes • A roadmap, not a specification. No attempt to map tasks to specific organizations
The DMAC Plan – first order guidance • COOS in RAs advise about IOOS NOW • DMAC Steering Committee designated initial guidance • Report standards and standards processes presently used to Ocean.US • Use FGDC (ISO 19115) metadata standards if starting out • Use community accepted standards otherwise • Create metadata in XML-schema with a style sheet • Gridded data – install server and provide access through OPeNDAP • Use RDBMS • OPeNDAP enabled • Enterprise GIS, OGC compliant • Data providers – ensure irreplaceable data are permanently archived • Archive Centers – structure archives to be accessible and DMAC compliant • Security – until IOOS has data and network security guidelines use those prescribed by like federal centers • Use NDBC services for mooring data • Many more, and will be updated, see http://www.ocean.us
Next Steps: Work on DMAC Plan Recommendations • New DMAC-Steering Team • Formed in April 2005 • Open, fair, balance representation • About 25 members • Objective: Minimally functioning DMAC framework – in the near-term
Advancing the DMAC PlanWorking Structure under the Steering Team **Expert Teams: Metadata & Discovery Standards Process Archive Transport & Access Caucuses: Private Sector International Modeling Working Groups: IT Security On-Line Browse Systems Engineering Status: All but two WGs have SOWs and ETs are being formed. **Possible areas of OHH Participation

E.G. SOW for the Archive Expert Team Statement of need brief, • Forge cooperation between multiple centers to insure: • Data flow integrity • Publish data for discovery and access • Stewardship and long-term curation • DMAC metadata and data transport methods are critical – cross communication with other ETs • Preserve data through life cycles of storage systems
SOW for Archive ET, continued Membership: • All US agencies with IOOS data responsibilities • International counterparts • Representative from National Archives (NARA) • Long term strategies and preservation policies • Members must have knowledge and have authority to advance ET goals at the organization level • Approx. 10 members
SOW for Archive ET, continued Short term Tasks (2005-2006): • Review and refine DMAC Plan with report to DMAC ST • Define archive critical metadata – provide to Metadata ET • Assess, inventory, and report on IOOS relevant archives • Access status • Metadata status • Identify preservation weakness • Identify gaps in irreplaceable data archives
SOW for Archive ET, continued Long term Tasks (2007-2008): • Demonstrate, test bed project, merging metadata from multiple ACs into DMAC data discovery portal • Use DMAC meta data standards and transport protocols for two-way data flow • Receipt and delivery of data • Establish comprehensive metrics – system wide • Composite data polices from all agencies • Participate with governing committees to form a IOOS data policy • Many other goals outlined in DMAC plan!
SOW for Archive ET, continued Schedule: • Form, to extent possible the Archive ET, October 2005. Current members: • Bob Keeley (MEDS/Canada) • John Lever (Navy/CNMOC) • Landry Bernard (NOAA/NDBC) • Steven Worley (NCAR/NSF) • Validate membership before DMAC ST, Nov. 2005 • Hold first AET meeting, early 2006 • Use, web forums, email, and twice annual meetings to address Short Term tasks
Conclusions: • IOOS and DMAC have begun • Much growing to do • Must keep up with rapid developments at COOS and RAs • Fostering broad participation is the challenge • Technology is tracking the need well • Our success will be measured by how well we fulfill the societal needs
