Studies in the Terrestrial Biosphere, the Atmosphere, and Ice Cores

Starting with the work of Ben Houlton, we have collaborated with the group of Lars Hedin in the Department of Ecology and Evolutionary Biology in isotope studies of terrestrial N cycling. We have also worked on the nitrate N and O isotopes in rain, snow, and ice as tracers of reactive nitrogen sources and processing in the modern and ancient atmosphere.

Reduced interannual rainfall variability in East Africa during the last ice age
C. Wolff, G.H. Haug, A. Timmermann, J.S. Damsté, A. Brauer, D.M. Sigman, M.A. Cane, D. Verschuren

Interannual rainfall variations in equatorial East Africa are tightly linked to the El Niño Southern Oscillation (ENSO), with more rain and flooding during El Niño and droughts in La Niña years, both having severe impacts on human habitation and food security. Here we report evidence from an annually laminated lake sediment record from…
