ApRES (Automated phase-sensitive Radar Echo Sounding) at Kamb Ice Stream (HWD1), 2019-2020
These data are described in detail by 'Melting and refreezing in an ice shelf basal channel at the grounding line of the Kamb Ice Stream.
ApRES observations were made in December 2019 and repeated in December 2020 at the same locations. Data collection and processing followed the method described in Stewart et al. (2019). ApRES dataset.zip' contains raw ApRES data and processed results from a spatial survey of basal mass balance - detailed in Sections 2.2.4 and 3.2.2 of:

- Statement
- While the ApRES can observe accretion, quantifying the rate is problematic due to the occurrence of multiple reflections from both the glacial/marine–ice interface and the marine–ice/water interface, and unknown changes in the properties of marine–ice (Vaňková et al., 2021). The values presented should be interpreted as an “apparent accretion” rate as described by Vaňková et al. (2021).
