Geophysical fluid dynamics laboratory review

Ocean Ecosystems and Climate Change

  • Enhanced foodweb dynamics in GFDL biogeochemical model (TOPAZ)

  • Expanded applications of GFDL models to marine resource prediction


Geophysical fluid dynamics laboratory review

How will climate change impact global fisheries production?

"We have low confidence in predictions of future fisheries production because of uncertainty over future global aquatic net primary production and the transfer of that production through the food chain to human consumption."

-K.M. Brander, 2007, Global fish production and climate

change, PNAS, 104(50), 19709-19714

The ratio of mesozooplankton production to primary production

~10% of primary production transferred to mesozooplankton production in upwelling systems; ~1% in sub-tropical gyres

A fractional change primary production causes a larger fractional change in mesozooplankton production

Geophysical fluid dynamics laboratory review

Incorporate enhanced ecosystem dynamics into:

Historical ocean/ice simulations forced with atmospheric reanalysis

Century-scale climate simulations

Interannual and decadal scale "initial value" simulations

Develop capacity to link with fisheries foodweb models(see Kearney poster)

Engage NOAA fisheries laboratories through postdocs and workshops to develop new and innovative applications of GFDL models

Toward marine resource prediction at interannual to centennial time-scales


Applying ipcc class models of global warming to fisheries prediction

Workshop to develop new GFDL model applications to fisheries prediction

June 15-17, 2009
