Conclusions and Perspectives
Photosynthetically Active Radiation

• Conclusions
• The model as currently parameterized was capable
  of reproducing broad scale patterns of nutrient
  concentration, primary production, and biomass of
  phytoplankton, microzooplankton and
  mesozooplankton on the northern Gulf of Alaska
  shelf for 2001.
• Remaining Tasks
• Get the physical model to run with tides.
• Run the model on the 3 km Gulf of Alaska grid for
  2001, 2002, 2003, 2005 and 2006.
• Major question
• Can the model reproduce the interannual
  variability observed in the field data?
