MBL MICRO-ECO DISCUSSION GROUP
Meets Thursdays, 2:30-3:30 PM, Starr 2nd floor classroom, unless otherwise stated.
MBL Micro-Eco Discussion Group, Spring 2012
January 26 -- Joe Vallino
Joe will present some results from the microcosm experiment he, Julie Huber, and Nuria Fernandez Gonzalez have been conducting. He suggests that ahead of time, you could go to the project web site and poke around to get oriented: http://ecosystems.mbl.edu/MEP/
For example you can see data here: http://ecosystems.mbl.edu/MEP/Experimental/ATBexp1/ATBexp1.html
