Assessing the contribution of super-resolution in satellite derived bathymetry in the Antarctic
Estuarine, Coastal and Shelf ScienceThe difficulty of defining the depth of near-shore seas (bathymetry) arises from the limits imposed by traditional ship-based approaches during data collection. Although LiDAR sensors with green lasers have been used to solve some of these problems, they come at a high cost in terms of their footprint and are prone to inaccuracies in turbid water.
