PERSPECTIVES FROM GODAE

the problem might favor an ensemble of initial conditions rather than a
single, high-fidelity product. For decadal variability and longer-term change,
GODAE focuses on the provision of consistent, high-quality analyses and
re-analyses of the ocean.
Coastal applications: Coastal applications will use GODAE ocean state
estimates as boundary conditions for coastal/ littoral zone hindcasts and
forecasts and analyses (Figure 3).
Figure 3. A schematic of the hypothetical nesting of a coastal application near Sydney within
the BLUElink ocean forecasting system (indicated by fine dots; see Schiller and Smith, this
volume) or a coarser seasonal prediction system “POAMA” (Wang et al., 2001).
It is not yet clear what the accuracy requirements are. Development of
GODAE products for these applications will represent a significant research
effort within the community. Issues of nesting of models of different
resolution, the importance of regional wave and surge models, consistency
in bathymetry, forcing, boundary configurations, and input to ecosystem
models are critical elements for collaboration. The end users will include
regional/local governments responsible for coastal management, as well as
coastal industries such as fishing and recreation.
The GODAE approach provides efficiency because the systems can
provide information/boundary conditions to multiple users, in a variety of
ways. In some prototypes the regional/local modeling is in-built to the
modeling system. In other cases the coastal modeling is part of the same
project so the interface issues are being solved as part of the project. In yet
other cases, boundary conditions are being provided to third parties who
