The model run that agrees best with Seward Line data (1999) is characterized by
a long period of upwelling between late April and the end of August. However,
1999 was not a year with strong upwelling at the Seward Line
(Stabeno et al., in press).
Results are similar with either type (low or high diffusivity/HNLC) of
oceanic boundary condition.

Depth averaged coastal copepod (C), oceanic copepod (NC), and euphausiid (E)
biomass in time. Red lines and numbers are measured biomass. Black lines are
simulations with diapause for the oceanic copepods, and the green lines are
simulations without it.
|
- Euphausiids are consistently overestimated by the model
- Model missed the early bloom of coastal copepods, but otherwise
they were in good agreement.
- Oceanic copepods show good agreement in spring, but the model
uderestimates them in late summer
- When diapause removed, the model results are closer to data
- Some species (e.g. Eucalanus bungii) diapause later
- These spesies may have been present on the Seward Line later in
the summer
