Geological mapping from the first German Antarctic North Victoria Land Expedition, conducted by eight scientists aboard the M.V. Schepelsturm in 1980. Fieldwork involved helicopter traverses and camps across the east and north of North Victoria Land. Mapping was performed at reconnaissance level, with detailed work at scales of 1:250,000 and 1:100,000.
Use Cases
- Map granitoid and Robertson Bay sedimentary rock distributions using the 1:250,000 scale geological mapping data.
- Analyze contact metamorphic aureoles around granites using field sample data from helicopter landing sites.
- Study regional geological structures in areas like the Morozumi Range using the more detailed 1:100,000 scale maps.
- Correlate rock samples and observations from specific field camp locations like Football Saddle and Robertson Bay.
Strengths
- Data covers a large geographical area across the east and north of North Victoria Land, Antarctica.
- Includes geological mapping at two specific scales: 1:250,000 and 1:100,000.
Limitations
- Dataset is over 40 years old, with potential staleness for contemporary geological studies.
- Specific data volume (rows, sample count) and file formats are unknown.
- Reconnaissance-level work may indicate variable detail or completeness across the surveyed area.
Provenance
- Source
- SCIOPS, via NASA Earthdata.
- Collection Method
- Field observations, sampling, and geological mapping during the GANOVEX I expedition, using field camps and helicopter transport.
- Time Range
- 1980 (expedition year).
- Freshness
- Data reflects a single expedition from 1980; no update frequency.
- Geography
- East and north of North Victoria Land, Antarctica, including specific glaciers, ranges, and bays mentioned in the description.
