Here is a quick note on each of the movies. All are from our
eddy resolving global calculation in which the same ecosystem model as
in our Science paper is run in a model with 18x18km resolution,
capturing some of the mesoscale eddy features of the ocean.

Chla1997.mp4 shows the models predicted Chla concentration (surface
10m) for the year 1997. Its the sum from all 78 phyto species. We've
used an empirical algorithm to relate biomass and Chla here. Its the
onset of the El Nino so the tropical pacific productive tongue shuts
down towards the end.

chl_cloern_seawifs.mp4 shows the same as above on the right (but for
years 1998 and 1999 I think). On the left, same scale, are monthly
estimates from remote SeaWiFS observations. You can see the La Nina as
the tropical Pacific tongue returns vigorously.

squirt.mp4 shows two "synechococcus-analogs" in the Atlantic. They are
very similar in physiology except for temperature adaptation. One of
them grows at mid-lats. The other is happy in the tropics but gets
advected by the Gulf Stream to mid-lats. Along the way it is
disadvantaged by cooler temps, but gets a shot in the arm from
additional nutrients. Its population manages to hold on as it is
advected out into the mid-latitudes where it is outcompeted ultimately.
This advection "seeds" other areas and promotes diversity.

phygrp_globe_land.mp4.  Here the colors represent the four main
functional groups which we collect: Diatoms (red), Prochlorococcus
(green), other small (blue) and other large (yellow) cells (described in
the papers). The color shading reflects the group while the
intensity/opacity of the color reflects the abundance. You can get a
feel for the biogeography of the four major groups represented. The
land is NASA's blue marble imagery. 

Thanks,

Bye for now,
