A paper investigating the mass balance of East Antarctica between 2003 and 2013 has been accepted for publication in Geophysical Research Letters. A key finding is that ice mass gains in the East Antarctic Ice Sheet are less than ice mass losses in the West Antarctic Ice Sheet, using the examined assumptions and a combination of diﬀerent datasets.
The work, made possible by GlobalMass and the NERC-funded RATES project, combined satellite altimetry, gravimetry (GRACE) and GPS data with prior assumptions characterising the underlying geophysical processes. The GlobalMass project will subsequently extend and expand the same methodology to include more direct observations and prior information, allowing us to solve simultaneously for all key geophysical processes relevant to sea level change on a global scale.
The paper is available as an Open Access publication here.
