Presentations at AGU 2017

Last week saw over 20,000 scientists from around the world gather in New Orleans for the annual American Geophysical Union (AGU) Fall Meeting. GlobalMass was represented in person by Jonathan Bamber, and results from our work were presented in two talks.

The first (invited) talk presented William Llovel’s investigations into the mass component of recent sea level changes. William has explored an alternative approach of attempting to improve our understanding of ocean mass trends through estimation of global ocean freshening based on salinity measurements from Argo buoys.

The second talk outlined Maike Schumacher’s recent work establishing a global GPS dataset that provides a ‘clean’ GIA signal and is, therefore, suitable to investigate the behaviour of global GIA forward models. The fully-automatic post-processing method she has developed has yielded a dataset of ~4000 GPS vertical velocity time series. These provide an observational estimate of global GIA uplift rates which will subsequently be used to improve existing global forward model solutions within our Bayesian Hierarchical Modelling framework.

Every December, the AGU hosts its Fall Meeting to promote the dissemination of scientific research to a wide variety of audiences, drive the advancement of science and innovation, inform policy, and facilitate essential collaboration between researchers and other stakeholders in the public and private sectors.
