Inference of the lithosphere of Northeast China from passive seismic receiver based methods »
The NE China plain (NECP) consists of complex lithospheric domains characterised by the co-existence of complex geodynamic processes such as crustal thinning, active intraplate Cenozoic volcanism and low velocity anomalies. The focus of this study is to constrain the complex lithospheric structure beneath Northeast...

Modelling the dynamics of past climate change »
I will discuss the dynamics of three different climate events in the past: the Paleocene-Eocene Thermal Maximum (PETM, ∼55 million years
before present) and Heinrich Events 1 and 4 (17.5-15.5ka BP and 40.2-38.8ka BP). The PETM was a period of rapid warming marked by a negative carbon isotope excursion and...

Global sea-level during the mid- to Late Pliocene (~3.3-2.6 Ma) and implications for polar ice sheet variability »
The mid-Pliocene (3.3 -3 Ma) has long been considered an analogue for future global warming with atmospheric CO2 concentration of 400 ppm, average surface temperatures 2-3 °C higher than pre-industrial and a lack of large continental ice sheets in the Northern Hemisphere. This period of equable climate...

Oxygen isotope systematics of ordinary chondrite chondrules: insights into the inner solar system planetary reservoir »
Triple oxygen isotope measurements (16O, 17O, and 18O) revolutionized our understanding of meteoritics and cosmochemistry since the discovery of large and ubiquitous oxygen isotopic anomalies in refractory inclusions within carbonaceous chondrite meteorites in the early 70s. Since...

The role of convection on the basal melting of Antarctic ice shelves »
Melting of Antarctic ice shelves has a large impact on ocean circulation, future sea level rise and the global climate. Most of the ice-shelves in Antarctica are sloped forward into the ocean forming an ice cavity underneath. The turbulent transport of heat and salt into the ice interface melts the ice and drives...

Glacial-interglacial hydrographic variability in the Bay of Bengal during the last 500,000 years: focus on Glacial Termination TIV »
The tropical Indian Ocean is a key area because of the interplay between hydrographic responses to strength variations of the Indian Monsoon and advection of Southern Ocean waters through its thermocline. Yet, long-term (102 to 105 years) evolution of this sector of the global ocean remains...

Carbon sequestration under the forearc by COH-fluid mediated carbonation of serpentinites and peridotites »
The carbon content in the atmosphere has a strong influence on climate and has changed dramatically over geological times. Consideration of the global carbon cycle has focused primarily on exchange between atmosphere, oceans and shallow crust because this likely mediates climate on millennial time scales. By...

Lessons from the Sudbury impact structure for the Hadean Earth »
We know little about the Hadean Earth but most agree that the entire inner Solar System was pummeled by impacting bolides. None of the terrestrial Hadean impact basins are preserved but by analogy with our neighbours, the Earth must have featured basins of up to thousands of kilometers across. Is there any hope of...
