Modern tropical marine ecosystems are generally oligotrophic and are dominated by calcifying photosymbiotic and photic organisms such as corals, algae and large benthic foraminifera, and to a lesser degree by heterotrophic carbonate producers such as molluscs or echinoderms. The complex structural framework as well as associated sediment production of coral reefs provide key geo-ecological functions such as habitat provisioning and coastal protection, beach nourishment, and island building or maintenance. Among the many regional and global environmental changes experienced by oceans are the alternation of ocean chemistry and temperature, sometimes at rates exceeding those in historical and recent geological records. These alterations may affect organismal physiology, and especially calcification mechanisms of marine skeletons and shells, and lead to shifts in biological communities, changing sediment generation and accretion patterns. The global impacts of climate change e. Ultimately, shifts in the benthic community composition can manifest in changes of sedimentation patterns, or carbonate production and erosion processes, and thereby diminish the important geo-ecological functions carbonate accreting ecosystems provide. As this can have severe consequences on the services of carbonate-building organisms and ecosystems, better knowledge on their resilience, i. Carbonate secreting organisms play an important role in tropical ecosystems as they are able to shape their environment by building the reef framework to provide habitats for other organisms. Their role in coastal protection and for resource management is essential in particular in densely populated coastal areas due to attenuation of wave energy. The Geoecology and Carbonate Sedimentology Group focuses on the effect of environmental change on calcifying organisms, carbonate sediment production, transport and depositional processes. We also use carbonate sediments as paleo-ecological archives of the biotic composition of ecosystems or to characterise the recent status and the short- or long-term changes of such systems. Furthermore, we use certain carbonate producers such as photosymbiotic foraminifera as bioindicators for ecosystem state, or as model systems to study photosymbiosis, e. For a better understanding of the impacts of changing environments to marine organisms and subsequent sedimentological processes, field studies are undertaken in areas of natural or anthropogenic extremes. These field studies may serve as analogues for scenarios predicted for the future scenarios. Correspondingly, remote and widely uninhabited field sites are used as references to study natural processes under minimal direct human aria alexander speed dating. These include a wide range of microscopy-based methodologies e. This serves to better understand the bleaching process, i. Integrating these diverse approaches and perspectives enables us to gain a better knowledge the small- to very large-scale changes caused by environmental disturbances, but also the processes involved in recovery or development of alternative ecosystems and their effects on the geo-ecological functions carbonate depositional ecosystem provide. Members of the working group Geoecology and Carbonate Sedimentology photo taken September Accelerating anthropogenic input of CO 2 into the atmosphere from fossil fuel consumption has caused an indelible imprint on ecosystems worldwide. This increase in CO 2 has both physical and chemical effects on the ocean evidenced by global climate change GCC; projected ocean warming as well as increased absorption of CO 2 into the oceans, causing ocean acidification OA; projected decrease in pH. Climactic change has also been linked with the degradation of several important ecosystems, including instances of severe coastal land loss aria alexander speed dating to storm surge scouring of beaches. To better understand the link between biological processes of organismal physiology individual calcification rates with ecosystem processes sediment dynamicsthe project will characterise calcification rates of common reef-building large benthic foraminifera LBFs to upscale these measurements to reef-scale estimates of carbonate production through geospatially-referenced satellite imagery. These field-based experiments will be complemented with manipulative aquaria experiments of OA and GCC to further our understanding of how beach nourishment will be altered by climate change. It is part of the cluster's Research Unit RECORDER that deciphers climate signals from marine sediments. For this, Sediment cores are analysed for proxies for seawater parameters and for aridity. This project is a collaboration with the King Abdullah University of Science and Technology KAUST at Thuwal, Saudi Arabia.
