GPS and ApRES data relating to the growth of Chasm-1, Brunt Ice Shelf from 2016 to 2023

The dataset consists of GPS data recorded from four sites close to Halley VI Research Station, plus ApRES data across the rift from 2017-2019. Both data types provide information on the width of an active rift propagating through the ice shelf. GPS sites advect with flow of the ice shelf, while ApRES is repositioned each year. The data were collected as part of the Lifetime-of-Halley monitoring programme.
