Mass balance of four East Antarctic outlet glaciers
This is the publisher's version, also available electronically from "http://www.ingentaconnect.com". The East Antarctic ice sheet (EAIS) is Earth's largest reservoir of fresh water and has the potential to raise sea level by 50 m. A significant amount of the ice sheet's mass...

This large imbalance for Byrd Glacier is inconsistent with other observations, and is likely due to an overestimation of accumulation rates across large regions of the interior catchment.
