Seoul meeting update/status: SC:

1. Seoulmeeting update/status: SC: Still have Wallace, Trull, Honda, Murty, Send, Karstensen, Osterhus, NIOZ, hopefully AOML, Brazil, Lankhorst, A.Sutton (NOAA OA program), L.Lorenzoni (IOCCP timeseries), 4 Korean PI/directors, 2 new participants from China, 2 new from Taiwan, NOAA program manager (Diane). Total (with DMT, Korean PI’s, and agencies) now 31 participants

2. Use Seoul meeting for: • - urgent business (requirements/metrics, products, increase • data flow, deep microcat scheme, MOIN conference) • get more participation/buy-in from Korea, China, Taiwan, Brazil • drive home message to NOAA that OceanSITES needsdedicated funding, like ARGO, as a program

3. Requirements/metrics documents outline Overarching goals, societal needs Processes, conditions, changes that need to be observed, needs quantified objective (e.g. reduce model uncertainty in airsea fluxes to 2W/m2, or determine global carbon inventory and its changes to XX accuracy, estimate boundary current transports to YY accuracy for closing global heat budgets, determine ocean productivity to within ZZ) – can specify time and space scales of interest. Critical locations and dominant global scales that need to be covered: are we interest in mean state or in variability – use global mean maps and global EOF patterns. Can start with known distributions (chl, CO2 flux, nitrate, iron, dust, species, etc) and Longhurst provinces. Later use EOFs from models using the property of interest.  maps by discipline (air-sea, physical, BGC&ecosystem)Later can project timeseries onto the EOF patterns. List of variables, depths, sampling intervals; minimum and desirable variables Check how many sites exist that (nearly) satisfy location and sampling requirements  percent completion Proposed products and indicators

4. Some proposed metrics (from Roger): • - The number of sites • - Number of sites * average # of variables * average # years duration • - A histogram of record lengths for the various sites, per variable/depth-range • - For each site/depth-range/variable, standard deviation/(record length in years) • - Within parts of the water column (to be defined) the average over all sites of (numberof observed variables)*(years of records) • Depth ranges might be ML, pycnocline, intermediate, deep and abyssal.

5. Thoughts for the physical requirements/sampling document • 1. Water masses/water mass formation and modification • 2. Circulation • a) large-scale upper ocean • b) thermohaline MOC and deep boundary currents • c) straits and overflows • d) Surface boundary currents • 3. Deep ocean • 4. Equatorial and monsoon circulation

6. plus 10-20 deep T/S sites per ocean http://visibleearth.nasa.gov/view.php?id=73580

7. Anything from Murty yet ?

8. Air-sea flux sites: "critical sites" are seen as places where extreme heat loss occurs (e.g. western body currents) and where error can be large enough in model or analysis fields to bias basin or global averages, or as characteristic regime places - trade wind sites, or as places where deep convection in the ocean occurs in response to surface buoyancy flux, or along the well-coupled equatorial regimes in each ocean. Developing the map is aided by efforts such as the CLIVAR Indian Ocean panel whose placed flux sites at places where model flux products had large disagreement. Input has been asked from Mark Bourassa and Sarah Gille if the CLIVAR High Latitude flux working group can recommend a set of specific sites to be added.

9. Status of requirements map for biogeochemistry/ecosystem ?

10. Potential OA observing system, building on OceanSITES(build on rationale for this… contact PMEL ?) • Yellow: collecting SOME OA parametersalready • Orange: likely to happen in next years • Red: unlikely to happen without strong push from this community Hausgarten OOI Canada K2/Jamstec PAP/UK BATS RAMA/PMEL ??Coral Seas Jamstec RAMA/PMEL Spot/Aucan ?? RAMA/PMEL OOI OOI Agulhas/PMEL Cloiker/Kerguelen ??? AA supply ships Jamstec The OA community needs to add/share funding, operational effort/cost/ship time/people,sensors, data processing/management; in a few cases take ownership of complete moorings.

11. Products and indicators • Atmospheric: air-sea fluxes • Physical: transports, upwelling indices, trends in physical properties • Biogeochemical, carbon, OA, Ecosystem:

12. OceanSITES bibliography We can assemble all publications from data from sites in the system. But many of those would also have existed without OceanSITES. Any better ideas ? Use digital object identifiers in the future to track publications using the data.

13. Seoul Meeting • Agenda items: • 1) Re-evaluate definition (scope) of the OceanSITES project and characteristics of sites in the system (one goal is endorsement of the new How-To document by the SC). Reconfirm and clarify prior discussions/decisions about narrowed focus of OceanSITES (what kind of sites and data are included/hosted). Sharpen rationale for sustained ocean observations and also explaining the societal need for them and the value to society of doing them. • 2) Review concrete requirements and measures of success (metrics). Small disciplinary teams will have created drafts of requirements for each discipline, describing the global networks needed e.g. for surface fluxes, circulation, ecosystem regimes, ocean acidification, etc. In Seoul, the SC will review, edit, and adopt those descriptions, possibly in break-out groups. Need to better justify high cost, what is being delivered and how can success be measured, why not possible with cheaper methods ? • 3) Review concrete products and indicators. The team will have generated some draft examples of products and indicators before the Seoul meeting. These will be reviewed, and approved or modified, and new ones recommended. • 4) Review current network status, discuss/approve and invite new sites. Use the meeting location in Seoul to invite and engage more participation from Korea, China, Taiwan, and discuss sites from there, including data access. Another (recurring) topic is how to distinguish and represent/count the regular TAO/TRITON/PIRATA network versus the enhanced and flux reference sites there. Update maps. • 5) Review modified MOIN document (backbone network of minimalist identical multi-disciplinary sites), the Halifax MOIN workshop proposal, joint actions with global OA program, and steps towards implementation.

14. 6) Path towards sharing of platforms, sensors, data expertise • 7) Make contact with other communities and programs, both by inviting their representatives to the Seoul meeting, and by sending OceanSITES representatives to them. • 8) Review status quick implementation activities, in particular Deep Observations, decide on next steps, and work with JCOMM/GOOS/FOO Deep Observing Strategy Group (G. Johnson, B.Sloyan) • 8) Improve OceanSITES website • 9) Funding, outreach, capacity building, future meetings; approach private foundations through each institution’s “private funding development office” ? • 10) Steps needed to increase data holdings and flows; decide on actions/consequences if sites do not deliver data (e.g. black symbols on map, removal from map, removal from inventory,… ?). • 11) Steps needed to increase OceanSITES data awareness/usage. • 12) Find/recommend new DMT chairs; provide guidance to/work with the Data Management Team. • 13) Other(input invited….)

15. To do before Seoul • Have draft of requirements document, at least maps with needed sites and proposed indicators/products • Disseminate documents for meeting (requirement/map drafts, indicator ideas, explanation of requirements from Legler, How-to document, etc) • - Look at system status (update about sites, new maps) and data inventory and microcat inventory/maps • Have draft MOIN update ? • Ideas for new DMT chair ?
