Here is a quick note on each of the movies. All are from our |
6 |
|
|
eddy resolving global calculation in which the same ecosystem model as |
7 |
|
|
in our Science paper is run in a model with 18x18km resolution, |
8 |
|
|
capturing some of the mesoscale eddy features of the ocean. |

Chla1997.mp4 shows the models predicted Chla concentration (surface |
11 |
|
|
10m) for the year 1997. Its the sum from all 78 phyto species. We've |
12 |
|
|
used an empirical algorithm to relate biomass and Chla here. Its the |
13 |
|
|
onset of the El Nino so the tropical pacific productive tongue shuts |
14 |
|
|
down towards the end. |

16 |
|
|
chl_cloern_seawifs.mp4 shows the same as above on the right (but for |
17 |
|
|
years 1998 and 1999 I think). On the left, same scale, are monthly |
18 |
|
|
estimates from remote SeaWiFS observations. You can see the La Nina as |
19 |
|
|
the tropical Pacific tongue returns vigorously. |

|
|
squirt.mp4 shows two "synechococcus-analogs" in the Atlantic. They are |
22 |
|
|
very similar in physiology except for temperature adaptation. One of |
23 |
|
|
them grows at mid-lats. The other is happy in the tropics but gets |
24 |
|
|
advected by the Gulf Stream to mid-lats. Along the way it is |
25 |
|
|
disadvantaged by cooler temps, but gets a shot in the arm from |
26 |
|
|
additional nutrients. Its population manages to hold on as it is |
27 |
|
|
advected out into the mid-latitudes where it is outcompeted ultimately. |
28 |
|
|
This advection "seeds" other areas and promotes diversity. |

phygrp_globe_land.mp4. Here the colors represent the four main |
31 |
|
|
functional groups which we collect: Diatoms (red), Prochlorococcus |
32 |
|
|
(green), other small (blue) and other large (yellow) cells (described in |
33 |
|
|
the papers). The color shading reflects the group while the |
34 |
|
|
intensity/opacity of the color reflects the abundance. You can get a |
35 |
|
|
feel for the biogeography of the four major groups represented. The |
36 |
|
|
land is NASA's blue marble imagery. |
