Gravitational waves: origins, detections, implications.

The existence of gravitational waves was predicted by Albert Einstein 100 years ago. Their detection has being extremely elusive and difficult. It was finally achieved with the gigantic laser interferometer LIGO in 2015. Since then, several events produced by the coalescence of binary black hole systems have been detected and measured. In this talk I will review the nature of gravitational waves, discuss how they can be detected depending on their frequency, and elaborate about the implications of this momentous discovery.

Owing in particular to contrasting geographical situations (Arctic sea ice surrounded by continents, Antarctic sea ice surrounding Antarctica) and much larger ocean sea ice heat fluxes in the Southern Ocean, the processes governing the seasonal, interannual and multidecadal variability of sea ice are very different from one hemisphere to the other. After a brief contextual setting of Antarctic sea ice with respect to what is known by most about the recent decay of Arctic sea ice, the presentation will give an overview of the processing driving the evolution of Antarctic sea ice. The talk will then cover the various existing hypotheses behind the changes in Antarctic sea ice cover over the last decades, with a focus on ice ocean interactions, and in a twofold modelling and observational perspective.
