Abstract: Abstract
The grounding line is a key element acting on the dynamics of coastal outlet glaciers.
Knowing its position accurately is fundamental for both modelling the glacier dynamics
and establishing a benchmark to which one can later refer in case of change. Here we
� �map the grounding line of the Astrolabe Glacier in East Antarctica (66 41 S; 140 05 E),
using hydrostatic and tidal methods. The first method is based on new surface and
ice thickness data from which the line of buoyant flotation is found. We compare this
hydrostatic map with kinematic GPS measurements of the tidal response of the ice
surface. By detecting the transitions where the ice starts to move vertically in response
to the tidal forcing we find control points for the grounding line position along GPS
profiles. With the help of a 2-dimensional elastic plate model, rigid elastic deviations are
computed and applied to these control points. Once the extent of the grounding zone,
the kinematic approach is consistent with the hydrostatic map. These two approaches
lead us to propose a grounding line for the Astrolabe Glacier that significantly deviates
from those obtained so far from satellite imagery.

. The Cryosphere, 6(5), 3667–3702.
Abstract: We present an updated and quality controlled surface mass balance (SMB) database for the Antarctic ice sheet. We retrieved a total of 5284 SMB data documented with important meta-data, to which a filter was applied to discard data with limited spatial and temporal representativeness, too small measurement accuracy, or lack of quality control. A total of 3438 reliable data was obtained, which is about four times more than by applying the same data filtering process to previously available databases. New important data with high spatial resolution are now available over long traverses, and at low elevation in some areas. However, the quality control led to a considerable reduction in the spatial density of data in several regions, particularly over West Antarctica. Over interior plateaus, where the SMB is low, the spatial density of measurements remained high. This quality controlled dataset was compared to results from ERA-Interim reanalysis to assess model representativeness over Antarctica, and also to identify large areas where data gaps impede model validation. Except for very few areas (e.g. Adelie Land), the elevation range between 200 m and 1000 m a.s.l. is not correctly sampled in the field, and measurements do not allow a thorough validation of models in regions with complex topography, where the highest scattering of SMB values is reported. Clearly, increasing the spatial density of field measurements at low elevations, in the Antarctic Peninsula and in West Antarctica remains a scientific priority.
