The Diatom Flora of Lake Kinneret (Israel) – Palaeolimnological evidence for Holocene climate change and human impact in the southeastern Mediterranean


I am a member of the CRC 806 in project B3 as research assistant since 2011. Since September 2013 I am working on my PhD (funded by the German National Academic Foundation), in which I am analyzing changes of fossil diatom communities during the Holocene in sediment cores from Lake Kinneret (Israel; Southeastern Mediterranean) and Laguna de Medina (Spain, Western Mediterranean).


Hannah Vossel, Project B3

The Mediterranean basin is a region of highly complex topography and climatic variability, such that our understanding of the past environmental variability is still limited. Diatoms (single-celled siliceous algae, Bacillariophyceae) are abundant, diverse and sensitive to a wide range of environmental parameters. They are often well preserved in lake sediment records, and have well-recognised potential to generate high-quality paleolimnological data.

In this talk I would like to present the results of diatom analysis of an 18 m sediment core from Lake Kinneret as part of a multi-proxy study of Holocene climate change and human impact in the Levant. Results are compared with other proxy data including pollen, and with output data from regional climate modelling, to strengthen interpretation of environmental change in the Southeastern Mediterranean.

I also would like to give a short inside-view to the newly discovered and described diatom species Cyclotella paleo-ocellata Vossel et Van de Vijver and point out my prospective project for the third year of my PhD.
