PC14A:
Assessing Ecosystem Variability from Paleoceanographic Archives II Posters


Session ID#: 11476

Session Description:
The assessment of climate-change impacts on marine ecosystems is currently significantly hampered by the lack of a sufficient number of long-term observations. Marine sedimentary archives provide a unique opportunity to obtain information on the magnitude of ecosystem variability, trends, changes of biogeographic ranges, and the extinction and emergence of species. Moreover, the analysis of ecosystem variability on longer timescales can inform about the response to known climate forcings as well as, for example, on the existence and occurrence to thresholds in ecosystems. Over the past years, progress in the development of proxies informing on key aspects of marine ecosystems as well as in obtaining high-resolution sedimentary sequences has opened new opportunities in marine-based paleo-ecosystem research. We invite contributions from all areas of paleo-ecosystem research, covering high-resolution reconstructions, proxy development, and modeling studies.
