Paleoclimate and Paleoenvironment Dynamics

Our primary research interest is the interplay between the processes that shape the Earth’s surface and their geodynamic counterparts at depth, in particular interactions among (paleo-)climate, landscape evolution, and mountain building. The terrestrial biosphere plays an important role in various aspects of this research including controls on atmospheric moisture transport, weathering and erosion.

We use stable isotopes including biomarker analytics and clumped isotope ( D 47 ) thermometry as tracers of (bio-)geochemical processes from the ecosystem to the orogen scale with a particular focus on the Cenozoic evolution of coupled climatic and tectonic processes.

Research interests

I focus my research on the development of Plio-Pleistocene African savannas. As a tool I work, among other things, with the analysis of stable carbon and oxygen isotopes from fossil herbivore and early hominin tooth enamel, as well as pedogenic archives, to reconstruct the development of C4 grasslands as a result of changing atmospheric pCO2-concentration, seasonality and distribution of precipitation, and (retreat of) tree cover. The southeast African savanna is here particularly interesting since the vegetation pattern can be correlated with paleontological data of the (dietary) adaptation and migration of the early hominins. In addition, I use clumped isotopes to detect paleotemperatures, which add valuable information to paleohabitat-reconstructions. Also, I am engaged in the method-development of simultaneous measurement of absolute concentrations of 71 elements in the periodic table  (6Li to 238U) via ICP-MS at New York University.

As a research affiliate at the Institute of Cognitive and Evolutionary Anthropology, University of Oxford, I am part of the Paleo-Primate-Project (PPP) in the Gorongosa National Park in Mozambique, which combines geological features of the two most fossil-rich paleoanthropological regions of Eastern and Southern Africa. The goal of PPP is to reconstruct the ecological and evolutional history of the southern part of the East African Rift from the Miocene to present.

Research interests and current projects

I am a geologist who uses stable isotope geochemistry to quantify paleoelevations of mountain ranges, as well as to reconstruct continental paleoenvironments. I establish the necessary chronological framework using magnetostratigraphy and 40Ar/39Ar geochronology. My goal is to link tectonic processes to changes in paleoenvironmental patterns (vegetation, hydrology, climate, seasonality). I work within the ‘Earth Surface Processes and Paleoclimate’ group of Andreas Mulch.

The Neogene paleoaltimetry of central Anatolia 
I employ stable isotope paleoaltimetry to reconstruct central Anatolian topography with the ultimate goal of identifying mechanism(s) of surface uplift as a result of mantle versus crustal processes. Results show that the southern Central Anatolian Plateau (CAP) margin reached similar-to-present elevations of ~2 km by 5 Ma.

Collaborators: D. Whitney (U Minnesota), G. Brocard (U Sydney), C. Teyssier (U Minnesota)

Neogene ecosystems of the present-day Central Anatolian Plateau (CAP)
Stable isotope geochemistry in fluvio-lacustrine sedimentary systems provides information on lake hydrology, as well as on paleoenvironment and paleoclimate. Many of the lakes in the CAP area exhibit evidence for an open hydrology, therefore indicating they were either outward draining (Black Sea, Mediterranean) or into a terminal lake. 
Soil carbonates provide a proxy material for paleovegetation reconstructions. Large variations in stable carbon isotope values indicate the dominance of C4 over C3 carbon fixation in central Anatolia over certain periods in the geological past. 
More recently, I have started to work on mammal tooth enamel from mammal fossil localities in central Anatolia, which provide a means of reconstructing paleodiet and seasonality. The variation in mammalian traits over geological time within nearby mammal localities suggests significant changes in paleohabitats and therefore vegetation and diet.

Geochronology of the Central Anatolian Plateau
For many of the fluvio-lacustrine Anatolian basins in which the proxy materials were sampled, I establish new age constraints by combining magnetostratigraphy, 40Ar/39Ar geochronology and existing mammal stratigraphy. The obtained age framework for the studied basins allows the paleoaltimetric and paleoenvironmental data to be put in a spatio-temporal framework.

Collaborators: C. Langereis (Utrecht U), J. Feinberg (U Minnesota), M. Cosca (USGS)

Mountain uplift and biodiversity in Anatolia
The world’s mountain ranges have long been recognized as biodiversity hotspots. In order to relate mountain uplift and environmental changes to biodiversity, I work with macroecologists and macroevolutionary biologists. Paleogeography, mammal diversity, dissimilarity and turnover, as well as paleovegetation and paleoclimate data are being combined to assess the effect of mountain uplift on biodiversity for a case study in Anatolia.

Past Research

Plate tectonic reconstructions and the restoration of the geometries of mountain belts in the greater Black Sea region
Rotational paleomagnetic studies led to the restoration of the original geometries of the Pontides (Turkey) and Lesser Causasus (Armenia, Georgia) orogens, as well as the Central Anatolian Crystalline Complex (Turkey). Using paleomagnetism, I produced plate tectonic reconstructions for Baltica, the southern Eurasian margin (Crimea, Pontides) and the South Armenian Block. The remagnetized nature of (mostly) marine carbonates caught my special attention. I also examined the Jurassic paleo-subduction zone configuration of the Black Sea region based on 40Ar/39Ar dating and the geochemical analysis of Crimean volcanic rocks.

• Carbonate clumped isotope (Δ47) thermometry 
• Stable isotope geochemistry (δD, δ18O, δ13C)

My primary research interest is the reconstruction of paleoaltimetry and paleoclimate using traditional stable and clumped isotope geochemistry.

During my thesis I focused on the topographic evolution and the climate dynamics of the Early Cenozoic North American Cordillera through integrated geochronology, sedimentology, stable isotope, and clumped isotope thermometry studies.

Current projects involve Miocene paleoclimate reconstruction of the western US and of the European Alps.

Research interests

I am currently working on organic geochemistry (biomarkers). My research focuses on the Miocene because it is a period with important and fast variations of the climate system. The aim of my study is to obtain a viable climatic model (temperatures and water budgets) for the Eurasian domain; a domain which has totally transformed since the early Miocene due to the birth of most of today’s orogen belts

One of my goals is to develop and apply new methods of paleoenvironmental reconstruction. My focus is the analysis of continental climate factors such as temperatures and isotopic compositions of fluids. Apart from fieldwork and operational support of the Stable Isotope Laboratory, I concentrate my efforts on methodological work on the geochemical proxy ‘clumped isotope’ and its temperature calibration for biogenic apatite.
