The GODAE Coastal and Shelf Seas Working Group
(CSSWG)mission and activities

• The usefulness of GODAE systems to coastal and
  shelf seas forecasting is one of the measures of
  the success of the GODAE project.
• The GODAE CSSWG conducts actions to promote the
  assessment and demonstration of the value of
  GODAE results for regional, coastal and shelf
  seas models and forecasting systems

• Continuously updated census of coastal projects
  worldwide using GODAE products
• CSSWG White Paper (79 pages, 3 editions so far)

2007 Liverpool Workshop - The Questions

• Level of awareness of available GODAE products?
• Access to data?
• Types of use?
• Level of satisfaction how measured?
• Scientific quality of downscaled simulations
  (comparison with data, extended predictability
  range, etc.)
• Utility for applications examples
• Help expected from a community such as this one?
• Other needs for products or help not covered at
  the present time?

5
2007 Liverpool Workshop - Some more specific
questions

• Sensitivity of coastal ocean systems to
  i.c.s/b.c.s/remote forcing
• Best type of GODAE product for one particular
  type of application
• Does downscaling add value to GODAE products?
  Does using GODAE b.c.s improve forecasts in the
  coastal products?
• Does assimilation of local observations add
  further value to coastal products? What
  observations would add value?

2007 Liverpool Workshop - Metrics types (WP)

• Final value utility (for application) -- local
  air/sea interaction (tropical cyclones), military
  (sonar prediction), oil industry (platform
  maintenance, oil spills), nuclear industry
  (radionuclide spills), biophysical parameters
  (primary production, fisheries, aquaculture,
  swimming water quality, sewage spills), sediment
  transport (beaches), maritime safety (iceberg
  drift, searchrescue), ship routing
• --gt more a driver than a metric defines
  variables to model look at
• Scientific value impact assessment --
  theoretical (sensitivity to i.c.s/b.c.s),
  quantitative empirical verification (local in
  situ data, gridded e.g. ALT/SST -gt Taylor dgms.,
  Class 1-3 metrics), visual inspection
  climatological knowledge (better features with
  increased resolution, transports at straits,
  seasonal variations)
• --gt more a concern than a driver refine
  strategy, define protocol
• Most talks showed dual viewpoint description of
  potential applications, then implementation of
  downscaling with impact assessment, but finalized
  studies with value metrics still rare
• Assimilation metrics (Class 4) still not
  widespread in CSS systems

2007 Liverpool Workshop - New topics wrt. WP

• Atmospheric forcing strategy wind/pressure most
  important forcings on shelves -- concomitant
  downscaling could be beneficial (HF coastal
  dynamics, orographic effects e.g. coastal
  sierras, etc.), impact of choice of atmospheric
  product (e.g. COAMPS vs. NOGAPS on shelf)
• Cross-scale interactions downscaling strategy
  must be compatible with coastal wave propagation
  (e.g. Kelvin wave off California), and with
  coastal/open ocean exchanges (e.g. Kuroshio
  meander triggering, Loop Current/Keys
  interactions) strategy wrt. boundary fluxes of
  biogeochemical properties between domains
• Outreach Several (many?) examples of CSS systems
  unaware of/not using larger-scale model outputs
• Future Support for Wide-swath altimetry, need
  for continued science forums, peer networking

Proposed session OS08 at AGU Fall Mtg. (San
Francisco, Dec.08)

• OS08 Advances in the prediction capabilities of
  interdisciplinary nested models in coastal and
  shelf seas
• Convenors P. De Mey, G. Halliwell, V.
  Kourafalou, R. Proctor
• (PDM and RP on behalf of GODAE CSSWG)
• Numerical modeling and prediction in coastal and
  shelf seas has greatly benefited from the
  development of state-of-the-art, data
  assimilative and data validated large scale
  models that can supply initial and boundary
  conditions to nested domains, allowing the
  resolution of several spatial and temporal
  scales. The Global Data Assimilation Experiment
  (GODAE) is one of the efforts that lead to the
  development of operational global and basin scale
  models that can provide modeling support to
  coastal and shelf models. Presentations
  affiliated with the GODAE Coastal and Shelf Seas
  Working Group are strongly encouraged, although
  all contributions addressing any of the following
  topics will be welcome.
• This session will address recent advances in the
  numerical modeling of processes in coastal and
  shelf seas and the development and assessment of
  methods that lead to coastal prediction and
  forecast. Emphasis will be given to nested
  hydrodynamic models that employ (a) boundary
  conditions from large scale operational products
  to address coastal to offshore interactions (b)
  data from observational networks for assimilation
  and validation. Nested ecosystem models of
  various complexities addressing the influence of
  physical processes on ecosystem dynamics and
  interdisciplinary coastal predictions are also
  welcome. The session will promote the discussion
  of methodologies that lead to reliable coastal
  forecasts (such as data assimilation, error
  analysis, influence of nesting, resolution and
  forcing) and the impact of sustainable,
  integrated modeling and observational networks
  that connect local, regional and global scales.
  Presentations that address the related
  socioeconomic and coastal management benefits are
  encouraged.
