Exploring barnacle exoskeleton formation »
Barnacles are ancient arthropods that, as adults, consist of a soft organism surrounded by a hard, often calcitic, outer shell that the organism produces for protection. While research has been done into the glue-like cement that...
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...
A journey from water in olivine to your cellphone screen »
In this talk, we will discuss how a global vision of molecular processes in silicates is important to understand how nanoscale processes influence megascale geological phenomenons and human material making. I will show how "big picture" questions in geosciences actually are intimately related to fundamental...
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...

Preliminary results from core description on the Chickyu.
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...
