AbstractUnderstanding of past climate changes is a key to predicting future global change. Various tools exist for the determination of long-term records of sea surface temperatures but quantitative methods for obtaining insight in long-term changes in continental climate are relatively limited. We have recently found fluvially transported lipids of soil bacteria in marine sediments deposited close to the outflow of large rivers. A study of surface soils where these bacteria thrive indicated that the composition of these membrane lipids is a function of mean annual air temperature (MAAT). Hence by analyzing these lipids in marine sediments a long-term record of past changes of MAAT integrated over the drainage basin of the river can be obtained. However, these reconstructions are as yet based on empirical correlations and need to be biologically validated. To this end, we propose to cultivate the soil bacteria producing the specific membrane lipids and to study the effect of temperature and pH on the membrane composition. Furthermore, we will study the mechanisms of transport of the soil bacterial membrane lipids to the ocean and compare the down-core changes in their composition with conventional MAAT proxies. This project, which combines microbiology, molecular ecology, lipid biogeochemistry and paleoclimatology, will bring this novel continental paleothermometer to maturity.
