Working group:
|
- Paleontology
and Biogeochemistry Group
|
|
Reseach area:
|
- Calcareous
microorganisms, bio- and chemostratigraphy, paleoceanography,
paleoecology, marine proxy development, and geochemistry
(trace elements, stable isotopes)
|
|
Research interest:
|
- Effect
of climate change on the dynamic and stability of marine
(paleo-) ecosystems and biogeochemical cycles
- Evolution
and dynamic of paleoclimate including the effects on
oceanic processes and biological evolution
- Effect of
changes in biodiversity and climate on the critical
function of marine ecosystems and biogeochemical cycles
The Paleontology
and Biogeochemistry Group (PBG) specializes
in Ceno- and Mesozoic process studies of extreme greenhouse
and icehouse conditions. Ongoing
research focuses on the development and application
of calcareous microorganism-
and geochemical-based proxies for deciphering the
history of marginal seas and open oceans, as well as the
dynamics
and
stability of ancient and modern marine ecosystems.
The research includes bio- and chemostratigraphic, paleoceanography,
paleoecologic,
and geochemical (trace elements, stable isotopes)
methods to gain rigorous insights into causes and consequences
of major
perturbations in the Earth system as documented for
example
by the burial of massive carbon-rich sediments (Oceanic
Anoxic Events) during the Mesozoic. A fundamental
understanding
of
such perturbations in the global carbon cycling and
the impact on the evolution of ancient marine ecosystems
is crucial for
our understanding of the nature and origin of petroleum
source rocks during Earth’s history and the
assessment of biotic changes associated with future
global change.
PBG projects
are interacting closely with the Integrated Ocean
Drilling Program (IODP).

Research opportunities:
|
B.Sc and M.Sc projects
are available along the following line:
- Studying
Ceno- and Mesozoic paleoceanographic and paleoclimatic
changes, from high- and low-latitudes, to ascertain
the various mechanisms by which organic- and carbonate-rich
sediments were formed and how this relates to the evolution
of marine microorganisms.
- Using a combined microfossil
and geochemical approach to date and understand the
distribution and formation of organic-
and
carbonate-rich sediments.
- Studying the impact of
extreme surface water warming and cooling on the evolution
of
marine ecosystems in marginal seas
and open oceans during the Ceno- and Mesozoic.
