Project Details
Description
The objective is to increase our ability to predict Antarctic ice shelf instability by assessing Holocene behaviour of warm Circumpolar Deep Waters (CDW) with the 10Be/9Be ratio.
This project will address three questions: 1) Do 10Be/9Be variations from Holocene sub ice-shelf sediments show past incursions of CDW? 2) are today’s ratios confirming the presence of CDW within the SIS cavity; and if so, are there major differences in modern ocean conditions compared to Holocene and, 3) if Holocene SIS instability is evident, was it caused by warm water CDW incursion or global sea level rise.
