January 2013 and 2014 field seasons in West Antarctica. This dataset describes the design, testing, and deployment of a clean hot-water drill system used to access Subglacial Lake Whillans and the Ross Ice Shelf grounding zone. It was developed by the ANDRILL Science Management Office at the University of Nebraska-Lincoln for the WISSARD project.
Use Cases
- Analyzing the design and performance of clean-access hot-water drilling systems based on the detailed system description.
- Studying the physical properties of subglacial water reservoirs based on reported salinity, temperature, and turbidity measurements.
- Modeling subglacial sediment composition based on descriptions of recovered core samples and shear strength.
- Planning future subglacial access projects based on documented drilling locations, depths, and logistical details.
Strengths
- Detailed documentation of a major scientific drilling project, with references to three related papers in the Annals of Glaciology.
- Includes specific geolocations (e.g., 84.240 S, 153.694 W) and ice thicknesses (~800 m, ~730 m) for drilling sites.
- Reports concrete scientific measurements from the subglacial lake, including salinity (0.37-0.41 psu), temperature (-0.558C), and sediment shear strength (2-6 kPa).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2013-01-31 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
