Forschung

My research mainly focuses on the lacustrine environments of tropical Africa. I am particularly interested in the African climatic variability and its impact on the ecosystems. I use lake sediment archives as well as ancient lake shorelines to reconstruct the past fluctuations of the African climate. I am currently developing a paleoproxy calibration of lipid biomarkers and reconstructing environmental changes in Cameroon (Western Central Africa) during the Holocene.

 

HYDROMAN: Impacts of hydrological changes versus human activity on the Central-West African forests during the Holocene (DFG Project GA 1629/2-1&2)

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/Barombi.jpg

Central-West Africa hosts the second largest contiguous expanse of moist tropical forest in the world, which is currently under severe threat of humans through deforestation and forest fires. During the Holocene those tropical forests underwent alternating periods of expansion and contraction, driven by climate variability, although during the last ~3000 years human activity associated with the spread of the Bantu-speaking people may have had an additional effect. To resolve the drivers and mechanisms, which have affected the Central-West African forests during the Holocene, we plan to analyse novel climate-proxies directly recording changes in the hydrological cycle in combination with vegetation-proxies and indicators of anthropogenic disturbances. We will mostly focus on a 20-m-long lake sediment core that we collected in the deepest part of Lake Barombi Mbo (105-m-deep, Southwest Cameroon) during January 2014.

 

Proxy development/calibration: the δD values of sedimentary lipid biomarkers in tropical African lakes (DFG Project GA 1629/1-1&2)

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/1.jpg

Interest in compound-specific hydrogen isotope ratio analysis as a continental palaeohydrological proxy has emerged during the past decade. To date, calibration studies for sedimentary lipid δD have only been available for mid- to high-latitude environments. However, a calibration focusing specifically on the tropical realm, which occupies half of the Earth’s surface, did not existed yet. The need for such calibration was also important because lipid biomarker δD values were increasingly used to reconstruct past changes in tropical African hydrology. Here, we aimed to identify the main environmental processes that control the hydrogen isotopic composition of sedimentary biomarkers and to develop a solid framework for the quantitative application of compound-specific hydrogen isotopes in tropical Africa. For this purpose, a 8°-long latitudinal transect of lake basins across Cameroon was chosen because it encompasses a wide range of contrasting climates and vegetation classes that are representative of the entire tropical African realm. We measured the δD values of sedimentary lipid biomarkers along extraordinarily steep climate and vegetation gradients as well as a wide range of possible water sources of the organisms, including lake water, precipitation, river water, groundwater, and plant-xylem water. Our approach allowed us to identify the potential source organisms and the environmental water pools feeding into lipid biosynthesis. Finally, our data validated the use of sedimentary lipid δD as a robust proxy for surface water δD and possibly for evaporation in tropical Africa.

Reconstructing lake levels from relict shorelines along the Northern Kenya Rift

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/Shoreline.jpg

Ancient shorelines can be used to reconstruct changes in the elevation of lakes through time. Shorelines are ubiquitous on the flanks of the Suguta Valley and Turkana Basin (Northern Kenya). We mapped and dated these prominent geomorphic features to reconstruct the water-level fluctuations in the Northern Kenya Rift during the Holocene period. We further used those deformed shorelines to infer the Holocene extension rate and structural style of the Northern Kenya Rift.

Forschung

My research mainly focuses on the lacustrine environments of tropical Africa. I am particularly interested in the African climatic variability and its impact on the ecosystems. I use lake sediment archives as well as ancient lake shorelines to reconstruct the past fluctuations of the African climate. I am currently developing a paleoproxy calibration of lipid biomarkers and reconstructing environmental changes in Cameroon (Western Central Africa) during the Holocene.

 

HYDROMAN: Impacts of hydrological changes versus human activity on the Central-West African forests during the Holocene (DFG Project GA 1629/2-1&2)

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/Barombi.jpg

Central-West Africa hosts the second largest contiguous expanse of moist tropical forest in the world, which is currently under severe threat of humans through deforestation and forest fires. During the Holocene those tropical forests underwent alternating periods of expansion and contraction, driven by climate variability, although during the last ~3000 years human activity associated with the spread of the Bantu-speaking people may have had an additional effect. To resolve the drivers and mechanisms, which have affected the Central-West African forests during the Holocene, we plan to analyse novel climate-proxies directly recording changes in the hydrological cycle in combination with vegetation-proxies and indicators of anthropogenic disturbances. We will mostly focus on a 20-m-long lake sediment core that we collected in the deepest part of Lake Barombi Mbo (105-m-deep, Southwest Cameroon) during January 2014.

 

Proxy development/calibration: the δD values of sedimentary lipid biomarkers in tropical African lakes (DFG Project GA 1629/1-1&2)

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/1.jpg

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/2b.jpg

Interest in compound-specific hydrogen isotope ratio analysis as a continental palaeohydrological proxy has emerged during the past decade. To date, calibration studies for sedimentary lipid δD have only been available for mid- to high-latitude environments. However, a calibration focusing specifically on the tropical realm, which occupies half of the Earth’s surface, did not existed yet. The need for such calibration was also important because lipid biomarker δD values were increasingly used to reconstruct past changes in tropical African hydrology. Here, we aimed to identify the main environmental processes that control the hydrogen isotopic composition of sedimentary biomarkers and to develop a solid framework for the quantitative application of compound-specific hydrogen isotopes in tropical Africa. For this purpose, a 8°-long latitudinal transect of lake basins across Cameroon was chosen because it encompasses a wide range of contrasting climates and vegetation classes that are representative of the entire tropical African realm. We measured the δD values of sedimentary lipid biomarkers along extraordinarily steep climate and vegetation gradients as well as a wide range of possible water sources of the organisms, including lake water, precipitation, river water, groundwater, and plant-xylem water. Our approach allowed us to identify the potential source organisms and the environmental water pools feeding into lipid biosynthesis. Finally, our data validated the use of sedimentary lipid δD as a robust proxy for surface water δD and possibly for evaporation in tropical Africa.

Reconstructing lake levels from relict shorelines along the Northern Kenya Rift

tl_files/arbeitsgruppen/ag_allgemeine_geologie/members/garcin/Shoreline.jpg

Ancient shorelines can be used to reconstruct changes in the elevation of lakes through time. Shorelines are ubiquitous on the flanks of the Suguta Valley and Turkana Basin (Northern Kenya). We mapped and dated these prominent geomorphic features to reconstruct the water-level fluctuations in the Northern Kenya Rift during the Holocene period. We further used those deformed shorelines to infer the Holocene extension rate and structural style of the Northern Kenya Rift.
