  Information - SSP8 Ostracoda as proxies for Quaternary climate change (co-listed in BG & CL)

Event Information
Ostracoda, common microfossils in both marine and nonmarine Quaternary deposits, are versatile palaeoclimate proxies via ecological, biogeographical and geochemical approaches. Alongside traditional methods such as the use of warm- and cold-water indicator species, a range of innovative and increasingly sophisticated techniques now exists. Analyses of the trace element and stable isotope compositions of their calcite shells provide proxies for climate-related factors such as temperature and salinity. GIS and transfer-function applications of large geographical databases have been developed, permitting (for example) the estimation of past air temperatures, water conductivity, or the climate-related solute history of a lake, and the use of deep-sea ostracod assemblages as water mass proxies for the interpretation of past changes in deep ocean circulation. This session will encompass all facets of the application of ostracods to Quaternary palaeoclimate studies.

We encourage contributions on all aspects of ostracods as proxies for Quaternary climate change, including indicator taxa, transfer function and Mutual Climate Range approaches, geochemical techniques, and comparative testing of one ostracod technique against another or of ostracods against other biological proxies such as chironomids, diatoms or foraminifera. We particularly encourage contributions from young scientists such as PhD students who may be looking for a first opportunity to make an oral presentation of their research at an international conference.
