Continuous marine high-resolution climate records with sufficient time resolution are needed to detect high-frequency variations in paleo-climate. Such records are rare but vital for our understanding of causes and consequences of climate and environmental change at decadal to millennial time scales. Deep basin pelagic sediments are usually degraded and lack the necessary time-resolution potential. In contrast, near-coastal high sedimentation rate sediments or basins with restricted circulation appear to have great potential for recording and preserving high resolution paleoclimate signals of Global importance. Examples of such basins are Cariaco trench, Californian borderland basins, Mediterranean, Black Sea, Baltic, fjords. In this session we welcome contributions on high resolution climate records that form the basis for the discussion on anthropogenic versus natural factors for short term climate variations in sub-recent and past. In addition, we welcome contributions that discuss processes that lead to preserved paleoclimate records, such as the relevant (paleo)oceanography, including residence time, productivity versus preservation, land-, and atmosphere-ocean interactions, seasonal contrast, and forcings/associations with solar- and Milankovitch cycles. Furthermore we invite contributions on proxies calibration and validation and multi-proxy interpretation in these high-resolution paleo-climate archives.
