The dataset consists of GPS data recorded from four sites close to Halley VI Research Station providing information on the width of an active rift propagating through the ice shelf. GPS sites advect with flow of the ice shelf. The data were collected as part of the Lifetime-of-Halley monitoring programme. This work was partially funded by NERC grant NE/X014991/1 (RIFT-TIP) and supported by NERC Antarctic Logistics and Infrastructure.

GPS data recorded from three sites close to the 2023 site of Halley VI Research Station. Data from site LL20 spans 2013 to 2017; Data from site ZZ6A spans 2017 to 2023; Data from site ZMET spans 2022 to 2023. The data are presented as RINEX observation files. The data were collected as part of the Lifetime-of-Halley monitoring programme. This work was funded by NERC grant NE/X014991/1 (RIFT-TIP) and supported by NERC Antarctic Logistics and Infrastructure.

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. This work was funded by NERC grant NE/X014991/1 (RIFT-TIP) and supported by NERC Antarctic Logistics and Infrastructure.
