An Arctic gateway trigger for Atlantic overturning at the Eocene-Oligocene Transition »
The Eocene-Oligocene Transition (EOT), approximately 34 Ma ago, is an interval of great interest in Earth’s climate history, due to the inception of the Antarctic ice sheet, major global cooling, and the likely inception of North Atlantic Deep Water. In line with geological evidence that the Arctic became isolated...
A continuous ice core record of climate to beyond a million years »
Ice cores from Antarctica, Greenland and mountain glaciers have provided great insights into climate on timescales from seasonal to glacial and geographic scales from regional to global. The rich archive of environmental tracers recorded in the snow makes ice cores arguably the most powerful single recorder of past...
2018 Inaugural Chappell Public Lecture »
The Research School of Earth Sciences is delighted to announce that Dr Carol D. Frost will be presenting the Inaugural Chappell Public Lecture on 22 November. The lecture series is in honour of Professor Bruce Chappell, one of the most distinguished geologists of his generation who made significant...
A shifting paradigm: aeolian sedimentation and climate forcing in the Asian interior »
Tibetan Plateau uplift has long been considered to be a main driving force for mid-latitude Asian inland aridity (AIA) and for deposition of thick aeolian sequences in northern China since the Miocene. However, a lack of well-dated and thick aeolian sequences has hindered testing of such relationships over longer...
Studies of water on Earth and in the asteroid belt »
It is increasingly accepted that the fast diffusion of water in glass renders measurements of melt inclusions suspect except in very small tephra. Therefore there is much interest in the use of water measurements in nominally anhydrous minerals such as clinopyroxene and application of a partition coefficient as...
Scale-aware, energetically consistent techniques for eddy-permitting ocean modelling - Scott Bachman (NCAR) »
Scale-aware, energetically consistent techniques for eddy-permitting ocean modelling Scott Bachman, National Center for Atmospheric Research (USA) Abstract: CMIP-scale ocean models are progressing ever further into a regime where the largest mesoscale eddies are...
Development and application of the pH-alkalinity system to monitor ocean pH and alkalinity »
Highly precise and accurate measurements of pH and alkalinity have become key scientific techniques to understand how rising anthropogenic CO2 emissions are affecting calcification processes on coral reefs. Hence to make high frequency (hourly) measurements of using the potentiometric method is time...
