ApRES Measurements at North-Western Ross Ice Shelf, 2021-Present
12 ApRES (Autonomous phase-sensitive Radio Echo Sounder) ice-penetrating radars were deployed on the Ross Ice Shelf in 2021/22 to measure basal melting. Each radar measures a profile of the ice shelf, typically at hourly intervals. Changes in the range of the basal and internal reflectors can be used to estimate basal melting. Instruments return a small subset of data in near real time via Iridium SBD telemetry, allowing a crude estimate of melting. Full resolution data is stored the instrument and can only be recovered with site visits. Instruments suffered failures during 2022, so the data sets have significant gaps within 2022/23.
Data type: Binary as described in ApRES manual
