The development opens the door to solving a problem that has stymied ocean
biologists for more than a century, and is revolutionary to our understanding
of how ocean biology and ecosystems, as well as carbon cycling, respond to
climate variability and change.
In order to determine ocean productivity, which is the rate of
photosynthesis, scientists must know plant growth rates and their abundance. 29 - Feb., Jan.org/meet/annual/

last summer in Colorado. It is an interdepartmental council with
13 Cabinet-level member organizations. The result was a significantly different view of ocean

It includes the study of the interrelationships among landforms, soil , vegetation, water (the oceans), and the climate.
