Directions and projects
: Sediment geochemistry.
Dynamics of carbon, oxygen, and nutrients in sediments with extremely deep oxygen penetration.
: an early Ocean analogue
A unique anoxic lake in Indonesia contains high concentrations of dissolved iron and hosts microbial communities similar to those that might have dominated oceans 2.5 billion years ago.
(Rwanda): a unique and dangerous lake
Possibly the most unusual lake in the World, Lake Kivu contains enormous amounts of dissolved gases in its deep waters that are both a economic blessing and a grave danger.
(East Africa): dynamics of nutrients
Lake Malawi is the major source of protein for the country of Malawi and it is under an increasing stress from growing population and agriculture.
Coastal marine hypoxia.
Oxygen depletion in estuaries and coastal areas is a growing problem caused by nutrient pollution, shifts in circulation, and warming.
August 2013. Arthur Aaberg defended his M.Sc. thesis.
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.
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.
