Links between marine and atmospheric processes oscillating on a millennial time-scale. A multi-proxy study of the last 50,000 yr from the Alboran Sea (Western Mediterranean Sea)

摘要: Abstract The large dataset obtained from the extensive study of IMAGES core MD95-2043 recovered Alboran Sea (Western Mediterranean) shows periodicities and phase relationships oceanographic atmospheric processes on a millennial time-scale. 1470-yr cycle is most significant, with exception records reflecting climatic or environmental changes land which show statistically significant 3300 8000 frequency bands. investigation these scale resolution allows us to establish evolution mechanisms that influenced Western Mediterranean region in course Dansgaard/Oeschger cycles. Accordingly, possible land–sea interactions can be identified situated context temporal succession different processes. For instance, Saharan dust supply Northern Africa appears lead high-latitude climate changes, suggesting low-latitude feedback were involved forcing variability westernmost Mediterranean.
