Dear Colleagues,

I am helping to organize a session at the Goldschmidt Conference this summer in Florence, Italy, that may be of interest to the paleontological community:

Geochemical and biological consequences of changes in the biological pump over geological time

Since the advent of photosynthesis, the vast majority of primary production in the oceans has occurred in the upper two hundred meters of the water column.  The spatial distribution of respiration, on the other hand, has likely varied substantially over geological time due to changes in the size and mineral content of primary producers and the evolution of animal consumers, all of which affect the net transport of organic matter from shallow to deep water (i.e., the biological pump).  In this session, we will explore the consequences of the evolving biological pump for ocean biogeochemistry and the evolution of marine ecosystems.

Abstract Deadline: April 12, 2013

Conference Dates: August 25-30, 2013
