Oxygen isotope systematics of ordinary chondrite chondrules: insights into the inner solar system planetary reservoir »

5pm 17 July 2018

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 »

5pm 10 July 2018

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 »

5pm 26 June 2018

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 »

5pm 19 June 2018

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...

Preparing for GRACE Follow-On: will we benefit from higher precision inter-satellite range measurements? »

12pm 13 June 2018

The twin satellites of NASA’s Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission launched on May 22 and will soon be producing data for the continuation of gravity field studies. Within the GRACE framework, solutions of the Earth’s gravity field are generated from high precision measurements of...

Lessons from the Sudbury impact structure for the Hadean Earth »

1pm 21 March 2002

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...
