Wolfgang Berger, the seventh recipient of the A.G. Huntsman Award, is
being recognized for his contribution to the understanding of the
carbonate preservation and dissolution cycles in pelagic sediments. Dr.
Berger's studies of ocean-basin history have focused on the climate and
productivity of the oceans by analyzing carbonates and their stable
isotopes in deep-sea sediments. He developed the concept of the "lysocline"
- the depth level on the seafloor which separates well preserved from
poorly preserved calcareous fossils - and its application to
paleoceanography. This research has focused on the variations through time
of the maximum depth of carbonate deposition. His studies of sediments as
historical records of the earth's climate have yielded important
parameters for assessing and ultimately predicting the effects of carbon
dioxide emissions on climate change.
