The solution has been update through the end of 2007 (calculations through end of 2008 are under way).

|
|
<p> Scientists at MIT have developed a new marine ecosystem model that allows its populations of |
| 141 |
|
|
phytoplankton to realistically evolve, reflecting the diversity in populations in the natural world. This |
| 142 |
|
|
should lead to a better understanding of the coupling between ocean and atmospheric chemistry. |
| 143 |
|
|
The model makes use of ECCO's ocean state estimate to capture the physical environment in |
| 144 |
|
|
which the ecosystem evolves. The study "Emergent Biogeography of Microbial Communities in a |
| 145 |
|

Chisholm was published in today's issue of <a href="http://www.sciencemag.org/cgi/content/abstract/315/5820/1843" target="_blank">Science magazine</a>.
