Satellite altimetry for glacier and ice sheet changes

Salle Lyot

- Geir Moholdt, glaciologue, North Polar Institute -   Résumé : Cryospheric altimeters like ICESat-1/2 and CryoSat-2 have opened up a well of possibilities for glaciological monitoring and research through their ability to resolve fine-scale surface elevations in sloping terrain. In this presentation, we will look at various types of glaciological applications and how these […]

Rare Earth elements: tracers of lithogenic inputs and dissolved-particulate exchanges in the Subpolar North Atlantic (GEOVIDE cruise, GEOTRACES GA03)

Salle Coriolis

- Marion Lagarde, Doctorante, Université Paul Sabatier, Toulouse, France -   Résumé : The objective of this thesis is to carry out a comprehensive documentation of dissolved and particulate concentrations of Rare Earths (REE) in the subpolar North Atlantic, along the GEOVIDE transect (N/O Pourquoi Pas? May-June 2014). This work aims to i) determine the […]

Adiabatic and Diabatic Signatures of Ocean Temperature Variability

Salle Coriolis

- Ryan Holmes, Océanographe, Université de Sidney, School of Geoscience -   Résumé : Anthropogenically induced radiative imbalances in the climate system lead to a slow accumulation of heat in the ocean. This warming is often obscured by natural modes of climate variability such as El Niño–Southern Oscillation (ENSO), which drive substantial ocean temperature changes […]
