(time interval of choise, for instance little icea age, Roman Warm Period, Medival Warm Period etc)
Aim: reconstruction of upper water temperaturtes and precipitation, pollution etc. in the coastal region off southern Italy.
Material/method: dinoflagellate cyst associations will be analysed by light-microscopy from core sediments. Organic fraction from core sediments will be concentrationd by chemical tratment (HCL and HF)
Knowledge to be present: General background knowledge about oceanography and dinoflagellate ecology
Special skills to be learned: Information about potential forcing factors (solar forcing, volcanic activity, differential climate modes etc.), combination with archeological information, Frequency analysis/wavelett analysis. Modern analogue techniques.
2. Species selective preservation of organic-walled dinoflagellate cysts
Aim: determination of the species selective degradation rates of organic-walled dinoflagellate cyst species.
Material/method: degradation experiments on core sediments collected from oxygen minimum zones can be carried out in temperature chambers. Degradation rates of individual cyst species will be studied along oxygen gradients in core sediments (for instance along so called „burn-down“ events of sapropels).
Knowledge to be present: basic knowledge about organic geochemistry, basic knowledge about dinoflagellate cyst ecology, basic knowledge about oceanography, basic statistical knowledge.
Special skills to be learned: Information about special palaeoceanographic changes that occur in relation to oxygen minimum development (for instance sapropel formation, brine formation/ventilation), multivariate analyses, modern analogue techniques, chemical redox changes related processes in sediments .
