OCEAN-CLIMATE SEMINAR- "Exploring atmosphere-ocean connections in the Western Mediterranean region during past climatic transitions: last terminations, glacial inceptions and some Holocene key changes", by Isabel Cacho

Title: "Exploring atmosphere-ocean connections in the Western Mediterranean region during past climatic transitions: last terminations, glacial inceptions and some Holocene key changes"

Lecturer: Isabel Cacho (UB, Spain)

Room: Z/033

The Mediterranean region is an exceptional sensor of climatic variability and in particular, the western Mediterranean Sea has demonstrated a tight connection with changes in the Atlantic Meridional Overturning Circulation (AMOC). Such a connection is further explored through an integrated study of cave speleothems and marine sediments reflecting climate conditions along the Iberian Peninsula. New speleothem records covering a transect from the most Atlantic to the most Mediterranean sectors across the Iberian Peninsula provide solid chronologies from Marine Isotopic Stage (MIS) 7 to 4 covering Terminations III and II and subsequent glacial inceptions. A clear picture stands out with a strong coupling between intense aridity phases and cold stadial conditions linked to AMOC weakening events and also to changes in the Mediterranean thermohaline circulation.

In contrast, a high resolution Younger Dryas speleothem record breaks with this overall stadial pattern showing an intra-event transition from extreme arid toward wetter conditions which is linked to circulation changes in the Atlantic Ocean. Temperature and humidity changes along the Holocene show a more complex pattern. A new high resolution W-Mediterranean surface temperature record supports maximum temperatures during the early Holocene while records from the north to the south of Iberia indicate limited water availability. Maximum in water availability occurred between 9-7 ka BP followed by an overall reduction in humidity, whose timing and pattern changes very much among the records, likely reflecting different proxy sensitivity, seasonality or regional diachrony.

Finally, both speleothem and marine records show significant variability in temperature and humidity pattern along the last 2 kyr, particularly the Little Ice Age appears as a very unstable climatic period where two different phases can be differentiated in terms of temperature and rain patterns, the main driver of the short term variability of this period seems to be associated to the Atlantic Multi-decadal Oscillation.
