Spring 2015 News
We published several new papers at the end of 2014. Be sure to check out:
Foster and Fulweiler's paper on Nitrogen Cycling in Waquoit Bay - here we examine long-term changes in benthic nutrient cycling. We found similar changes over the last three decades as has been observed in nearby Narragansett Bay.
We took to the woods to examine the potential impacts of elevated CO2 on the Terrestrial Silica Pump in a recent Frontiers paper. Here we discuss how changes on land could have important and thus far unexplored impacts to Si availability in downstream receiving waters.
Holly Emery and Tim Maguire presented their research at the BU Biogeosciences Research Symposium. The event was a first for the program and a great success overall.
We welcome a new postdoctoral associate to the lab, Dr. Priya Chowdhury. Priya has been busy processing samples and applying for funding!
