September 23, 2016. Our paper in PNAS
points to a way to forecast microbiomes in the ocean and stratified
lakes, by linking geochemical and microbial "omics" modeling. See
also UBC press release and here.
August 2016. The contribution of sediments to phosphorus cycling in lakes is reviewed in a book chapter published by Taylor&Francis.
December 2015. A story in the EARTH magazine highlights our Geology paper. See also UMD press release and the original story.
May 2015. Our paper
describes how the decomposition rates of organic carbon in freshwater
follow a simple power law as a function of carbon age and demonstrates
how burial efficiencies in sediments can be theoretically predicted for
modern and ancient oceans.
May 2015. A paper
by Sundby et al. is published that investigates when Mn-rich layers in
the Arctic Ocean may become modified within the sediment on
glacial-interglacial time scales.
March 2015. A paper by Dittrich et al. characterizes the geomicrobiology of Fe-rich layers in Lake Superior.
November 11, 2014. UMD homepage highlights our research.
November 6, 2014. Our paper in Science suggests low concentrations of sulfate in the ancient oceans seawater. See also the press release and the Science editorial.
October 2014. Our paper documents the warming of surface and deep waters of Lake Kivu.
September, 2014. Mojtaba Fakhraee started his Ph.D.
August 2014. A Mac version of the diagenetic model LSSE-Mega is available.
August 15, 2014, a master class on sediment
geochemistry and diagenetic modeling was given at the University of Western
August 12, 2014, a public lecture on African Lakes was given at the University of Western
June 30, 2014. Jiying Li has defended her Ph.D. thesis on sediment geochemistry in lakes Superior and Malawi.
June 2014. The graphical user interface for the sediment diagenesis model LSSE-Mega
is updated and available for download.
January 2014. Research cruise on Lake Malawi.
Redeployed moorings, obtained water samples. One of the immediate
research goals is to identify causes of recent fish kills and the
future responses of the lake to changing climate and land use.
December 2013. Our new paper
on the N cycle in Lake Superior balances the previously enigmatic
nitrogen budget for the lake and suggests ways of estimating
denitrification in the abyssal ocean.
August 2013. Arthur Aaberg defended his M.Sc. thesis.
Media presentation by Amy Kireta featuring our team on Blue Heron.
March 2013. Fieldwork on Lake Kivu. Recovered a set of gravity cores. Obtained temperature record from 355 m depth.
Our session at IAGLR 2013: African Great Lakes in Transition.
December 2012. Matt Kistner has defended his M.Sc. project.
September 2012 Field trip to Lake Kivu.
