Antarctic subglacial carbonates as archives of subglacial volcanism and Life in extreme conditions - Samples

This dataset lists samples of carbonate crusts formed under the ice of the East Antarctic Ice Sheet. These crusts mostly consist of Calcium Carbonate (CaCO3), and have ages spanning from older than 400,000 years to circa 17,000 years.The dataset "samples" provides the name for each specimen, where it was collected (Geographic Coordinates), its mineralogical composition and where the samples are archived.The list of samples is: PRR13055 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2PRR13074 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 PRR13290 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 PRR13081 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 PRR16794 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite PRR23247 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 PRR23258 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 PRR23259 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 PRR39222 Elephant Moraine Geographic Coord: -76.313 157.244 Composition: Calcite plus SiO2 VH-V2 Vestfold Hills Geographic Coord: -68.570 78.364 Composition: Calcite, Aragonite, silicates SiO2BH1 Bunger Hill Geographic Coord: -66.264 100.860 Composition: Calcite, Aragonite (?), silicatesBV8 Boggs Valley Geographic Coord: -71.912 161.525 Composition: Calcite BV9b Boggs Valley Geographic Coord: -71.912 161.525 Composition: Calcite All the Elephant Hill Moraine samples were obtained from the Polar Rock Repository, Ohio Uni (US), which lends samples for scientific research upon request (visit https://bit.ly/3kfHtgi). Samples from Vestfold Hills, Bunger Hill, Boggs Valley were sourced from the collection of Paul Augustinus, University of Auckland, New Zealand. All Boggs Valley samples were collected during the K15A event supported by Antarctica New Zealand.
