AU_AADC collected oceanographic and glaciological data from multiple boreholes drilled through the Amery Ice Shelf in East Antarctica. The dataset includes CTD profiles, current meter data, temperature measurements, sediment cores, and video footage of the cavity beneath the shelf. Measurements were made to understand melt and refreezing processes affecting the Antarctic mass budget.
Use Cases
- Model basal melt rates using CTD profile data and temperature measurements across the ice-water interface.
- Analyze ocean circulation beneath the shelf with Aquadopp current meter data and CTD moorings at multiple depths.
- Study sediment composition and benthic life from 0.5m and 1.5m sea floor sediment cores and video footage.
- Correlate surface tidal motion with subsurface processes using GPS records of surface elevation.
- Investigate borehole geometry and ice shelf structure using caliper profile data.
Strengths
- Data collected from six distinct boreholes (AM01 to AM06) providing spatial coverage.
- Includes multiple instrument types (CTD, current meters, thermistors, GPS, video) for multi-modal analysis.
Limitations
- Specific row counts, temporal coverage, and geographic coordinates for each measurement are unknown.
- Data is fragmented across child records for each borehole and instrument, requiring integration.
