The dynamics of the Lambert-Amery glacial system and its response to climatic variations ...
Antarctica's current and future contribution to sea level rise is uncertain, with changes in ice dynamics along the coast leading to mass loss while increasing precipitation in the interior is leading to mass gain. The Lambert-Amery glacial system drains a large region of East Antarctica, with...

Antarctica's current and future contribution to sea level rise is uncertain, with changes in ice dynamics along the coast leading to mass loss while increasing precipitation in the interior is leading to mass gain. The Lambert-Amery glacial system drains a large region of East Antarctica, with the two largest glaciers within the glacial system, the Lambert and Mellor glaciers, having a substantial volume of ice grounded below sea level, suggesting a risk of marine ice sheet instability. The velocities of Lambert-Amery glacial system have been observed to be stable between 1968 and 1999, albeit with limited sampling. Recent mass balance and gravimetry studies also suggest a system in near balance. Here, visible spectrum satellite images between 2004 to 2012 have been used to compute surface ice velocities using a feature tracking approach. No significant changes in velocity were observed over the study region that included the Amery Ice Shelf adjacent to the grounding line and its three main tributary ... |
