  • Automated weather stations were installed to measure local scale weather conditions at Miers Valley, Miers Ridge, Commonwealth Glacier, Cape Christie, and Haystack Mountain. Miers Valley, Miers Ridge and Haystack Mountain stations have been operating since early 2021. Commonwealth Glacier and Cape Christie were installed in December 2022, and 2023, respectively. Data are available on request in NetCDF. Parameters: - average air temperature (C) - average relative humidity (%) - average short wave in (W/m2) - average pressure (hPa) - wind speed (ms-1) - wind direction (true bearing degrees) - wind standard deviation Coordinates: - Miers Valley (-78.09805, 163.794283) - Miers Ridge (-78.123205, 163.863319) - Commonwealth Glacier (-77.563987, 163.281064) - Cape Christie (-72.29722222, 169.9847222) - Haystack Mountain (-77.05, 162.585) GET DATA: marwan.katurji@canterbury.ac.nz

  • Geodetic GNSS (Global Navigation Satellite Systems) and GNSS-RR (GNSS reflectometry /refractometry) experiments sharing a common tower and power supply were installed at Kamb Ice Stream site 3 (-82.628074, -156.306129). GNSS logging was set at 30 second intervals and data were saved in. sbf format. Deployments were used to capture the motion of the ice stream and ice shelf with a particular focus on the grounding zone. Total stations will also be used to monitor ice motion and deformation. These data combined provide boundary conditions and reveal controlling processes (ice deformation and tidal processes). GET DATA: r.levy@gns.cri.nz

  • Geophysical observations around the Kamb Ice Stream 1 (KIS1) borehole (-82.7841067, -155.2626683). Seasonal and winter-over GPS deployments were used to capture the motion of the ice stream and ice shelf with a particular focus on the grounding zone. Total stations will also be used to monitor ice motion and deformation. These data combined provide boundary conditions and reveal controlling processes (ice deformation and tidal processes).

  • Geophysical observations around the Kamb Ice Stream 2 borehole (-82.47040333, -152.29192167). Seasonal and winter-over GPS deployments were used to capture the motion of the ice stream and ice shelf with a particular focus on the grounding zone. Total stations will also be used to monitor ice motion and deformation. These data combined provide boundary conditions and reveal controlling processes (ice deformation and tidal processes).

  • AntAir ICE is an air temperature dataset for terrestrial Antarctica, the ice shelves, and the seasonal sea ice around Antarctica in a 1km2 spatial grid resolution and a daily temporal resolution available from 2003-2021. AntAir ICE was produced by modelling air temperature from MODIS ice surface temperature and land surface temperature using linear models. In-situ measurements of air temperature from 117 Automatic Weather Stations were used as the response variable. Each day has a bricked spatial raster with two layers, saved as a GeoTIFF format and in the Antarctic Polar Stereographic projection (EPSG 3031). The first layer is the predicted near surface air temperature for that day in degree Celsius * 10 and the second layer is the number of available MODIS scenes for that day ranging from 0 to 4. Areas with cloud contamination or without sea ice are marked with no data. Files for each year (2003-2021) are compressed with a ZIP files for each quarter. Python 3.8 was used for conversion of the MODIS products from HDF files to raster and all data handling and processing was thereafter done in R version 4.0.0. All data processing and modelling procedures are available as R scripts on a public Github repository: https://github.com/evabendix/AntAir-ICE. Using this code it is possible to download new available MODIS LST and IST scenes and apply the model to continue the near-surface air temperature dataset.

  • Data target a major subglacial outlet river emerging from beneath the Kamb Ice Stream (KIS). These data were used to determine both the role of water beneath the ice sheets and the ice-ocean interactions that take place once this water emerges into the ice shelf cavity.

  • This metadata represents ApRES (Autonomous phase-sensitive Radio Echo Sounder) measurements conducted at Kamb Ice Stream 1 (KIS2) since 2019. Experimental imaging ApRES profiling across the channel axis and low-frequency radar profiling were used in a grid pattern around the KIS2 borehole. ApRES observations and radar profiles were carried out both at and near the boreholes at both sites, with gridded observations extending over multiple kilometers around each borehole. A continuous ApRES deployment has been established, consisting of 31 stations that recorded observations at 15-minute intervals. The data collection included transects and short-term (several weeks) repeat measurements across key features, such as the grounding zone and subglacial channel, within a 50-kilometer radius of the borehole. This dataset provides subglacial dynamic and structural characteristic data of the Kamb Ice Stream. GET DATA: r.levy@gns.cri.nz

  • 50 TMS Soil Sensors were deployed in Taylor Valley from December 2021-January 2023 to measure temperature (air, land surface and soil) and soil moisture. The sensors record data every 15 minutes and are placed in nested plots of 2x 1km^2 plots with 3x30m^2 nests and 3 sensors in 3 x 1m^2 plots. Data are available in csv file format.

  • This metadata record represents the data from gravity measurements at Kamb Ice Stream 1. 30 line kilometers of gravity data were collected in front of the Kamb Ice Stream Grounding Line to charactersie the water column beneath the Ross Ice Shelf and the sedimentary strata beneath the sea floor. A 20-km long line was collected ~10km offshore and parallel to the grounding line. A 10-km corossing line was collected perpendicular to the grounding line. Gravity measurements were made using a Lacoste and Rhomberg D meter tied to a local base station and back to Hut Point Peninsula base stations. GET DATA: andrew.gorman@otago.ac.nz
