Quantification of paleotemperature changes during isotopic stage 2 in the La Draga continental sequence (NE Spain) based on the Mg/Ca ratio of freshwater ostracods
Past summer temperature changes are quantified from the La Draga sequence (Banyoles, NE Spain) during Stage 2 (24-10 ka BP), using trace-element content in lacustrine ostracod valves. The high resolution results from this new method are compared to summer paleotemperature reconstructions from sequen...

In NE Spain and offshore Portugal, the coldest part of Stage 2 is not documented at the classical date of similar to 18 C-14 ka BP (similar to 21.5 calendar ka BP) but rather occurred later date of ca. 17-15 ka cal.
