description:

This GIS dataset includes 16 surficial material units. Unit classifications are based on the Geological Survey of Canada Surficial Data Model Version 2.4.0 (Deblonde et al. 2019) because of its focus on glacial processes and glaciated environments. Units are defined based on the genesis of their dominant materials and their morphology, depositional environment, and thickness. Numbers denote subcategories. Most unit boundaries are gradational. Unit boundaries were mapped from aerial photography (Australian Antarctic Data Centre 1997), satellite imagery (DigitalGlobe Inc 2018), and field observations. The moraine complex (Tm) and Sørsdal Formation (Tv/GMo) boundaries are based on published boundaries (Australian Antarctic Data Centre 1997; Harris 1999) and have been refined further with remote sensing interpretation. Fieldwork was conducted in the 2018/19 and 2019/20 summer seasons, supported by the Australian Antarctic Program under Australian Antarctic Science Project 4393. Mapping was completed at 1:2000 and is best viewed in a digital format. |
