Antarctic drainage basins delineation
Listed in ScienceDB
On the basis of the highest accuracy and most complete MEaSUREs Phase-Based Antarctica Ice Velocity Map available, we propose a weight-balanced approach to extract Antarctic ice flow lines.
Description
This data is used to delineate Antarctic drainage basins on the basis of Antarctic (Ice sheet Mass Balance Inter-Comparison Exercise)IMBIE basins.The different flow directions at the adjacent basin boundaries from the ice flow lines offer the crucial delineation criterion, which is the key insight behind Antarctic basin re-delineation.
To distinguish the ice flow lines from each other, we represent the flow lines with different colors. For adjacent basins, we reclassified the boundaries of adjacent basins by tracing the flow trajectories of flow lines at the boundaries of adjacent basins. In contrast to the boundaries of adjacent basins, we retain and keep the boundaries of ice shelves in Antarctic IMBIE basins since they were based on InSAR-derived grounding lines with high accuracy.

As a result, the boundaries of all adjacent basins were redefined to generate the re-delineated Antarctic basin systems.
