Personal Perspective? Scientific analysis, implementation, and the development of products and services associated with specific in-situ observing systems.

GOOS n Goals: –To specify the marine observational data required to meet the needs of the world community of users of the oceanic environment; –To develop and implement an international coordinated strategy for the gathering, acquisition and exchange of these data; –To facilitate the development of products and services based on the data and widen their application in the use and protection of the marine environment; –To facilitate the means by which less-developed nations can increase their capacity to acquire and use marine data according to the GOOS framework; –To coordinate the ongoing operations of the GOOS and ensure its integration within wider global observational and environmental management strategies.

GOOS n Initial Observing System (IOS): –The operational ENSO Observing System in the tropical Pacific, including the Tropical Atmosphere Ocean (TAO) array of buoys. –Meteorological measurements from the Voluntary Observing Ship (VOS) network of the WMO. –Upper ocean measurements of the Ship of Opportunity Programme (SOOP). –Fixed and drifting buoys coordinated by the Data Buoy Cooperation Panel (DBCP). –The Global Sea Level Observing System (GLOSS) network of tide gauges. –The Global Coral Reef Monitoring Network (GCRMN). –Ocean observations from the operational satellites of NOAA and other entities………...

GOOS –The Continuous Plankton Recorder (CPR) programme. –The ICES International Bottom Trawl Survey (IBTS) of the North Sea. –Time Series Station 'S' off Bermuda. –Time Series Station Bravo in the Labrador Sea. –The Global Telecommunications System (GTS) of the WMO. –The Global Data Centre of the US National oceanic and Atmospheric Administration (NOAA). –The Global Temperature and Salinity Profile Programme (GTSPP).

GOOS Other contributions to the GOOS-IOS, include: –Selected ocean observing satellite missions. –The US PORTS programme. –Appropriate parts of the IOC Intergovernmental Oceanographic Data Exchange (IODE) programme. –Appropriate components of national observing systems (e.g. US Sea Ice Centre) –Appropriate commercial observing systems (e.g. oil platforms) –The international Mussel Watch programme –Appropriate parts of the IOC's Harmful Algal Bloom (HAB) programme.

GOOS n Data and Information Management: –GOOS is building on a number of past initiatives in managing data on a global scale for the purpose of providing environmental information to a wide range of users. –To meet the requirements of all users, GOOS will provide for: all pertinent data and products to be identified and made available to those adding value international communication networks and efficient, standard formats and codes to make best use of them Advanced quality control and validation systems generation of high level products archival methods that retain the value of historical data an integrated international data base

GOOS n Products: –A number of operational centres currently make contributions to GOOS.(e.g. centres involved with climate prediction, ocean and marine forecasting, etc) BMRC/NMOC Analysis of upper ocean thermal field (T150, August 1998)

GOOS n Pilot Projects: –NEARGOOS Pilot Project shared by Japan, China, the Republic of Korea and the Russian Federation. –EuroGOOS regional projects (Arctic, Baltic, Mediterranean, NW Shelf, Atlantic). –Western Indian Ocean Marine Applications Project (WIOMAP). –Pilot Research Array in the Tropical Atlantic (PIRATA). –Rapid Assessment of Marine Pollution (RAMP) pilot project –Global Ocean Data Assimilation Experiment (GODAE), including a major profiling float programme called Argo.

Global Ocean Data Assimilation Experiment (GODAE) n Fundamental objective: A practical demonstration of real-time global ocean data assimilation in order to provide a regular, complete depiction of ocean circulation at time scales of a few days, space scales of several tens of kilometres, and consistent with a suite of remote and direct measurements and appropriate dynamical and physical constraints.

Global Ocean Data Assimilation Experiment (GODAE) n Associated objectives: –Provision of suitable oceanic boundary conditions for regional applications such as coastal ocean prediction systems; –Provide a description of the ocean circulation and physics upon which more specialised systems, such as biological models, can be developed and tested –Provide a foundation for hypothesis testing, process studies and further experimentation, much commonplace in numerical weather prediction today;

Global Ocean Data Assimilation Experiment (GODAE) …..associated objectives (cont.): –Provide initial conditions for climate predictions and analyses for validation of climate simulations; –Provide a unifying target for various research enterprises (observational, theoretical and modelling) over the coming years; and –Provide a method for systematic handling, quality control and scientifically consistent interpretation (analysis) of additional data sets such as those from process studies and arising from incidental exploration.

Global Ocean Data Assimilation Experiment (GODAE) n Data requirements: –Any degradation in the availability of remotely sensed data would seriously compromise both the development and implementation of GODAE. –Continuity of data streams is essential, especially for operational demonstrations. –Ability to identify the utility and availability of data sets to GODAE is important. –Compatibility of data sets to facilitate use and integration. –Timeliness of delivery (e.g. real-time products for real-time applications).

Global Ocean Data Assimilation Experiment (GODAE) n Components (of equal value and to be integrated): –Global models of at least eddy-permitting resolution –Variety of space-borne systems »altimetry »scatterometers »operational meteorological satellites »sea surface temperature »ocean colour »advanced telemetry and communications –Global direct (in-situ) ocean observation network »subsurface moorings »merchant vessels »autonomous floats »acoustic thermometry

Integrated Global Observing Strategy (IGOS) n IGOS intends to unite the major satellite and ground based systems for global environmental observations of the atmosphere, oceans, and land, in a framework that delivers maximum benefit and effectiveness in their final use “The Global Observing System is only as strong as its weakest link”
