Bathymetric Contours for 14 Lakes in the Vestfold Hills, Antarctica

Vestfold Hills Lake Bathymetry contains bathymetric contour data for 14 lakes and fjords in the Vestfold Hills, Antarctica. The data was collected by the Australian Antarctic Data Centre using echo sounding and weighted line methods, with positional accuracy ranging from ±5 meters to ±2 centimeters. The dataset was last updated on March 15, 1999.

Use Cases

• Modeling lake volume and water storage capacity based on bathymetric contours.
• Analyzing underwater topography for geological or glaciological studies based on depth and position data.
• Creating base maps for ecological surveys of Antarctic lakes based on the included water body list.

Strengths

• Includes data for 14 distinct water bodies, such as Ace Lake and Ellis Fjord.
• Specifies positional accuracy (±5 meters for most lakes, ±2 centimeters for Ellis Fjord) and depth accuracy (±2 meters).
• Describes specific collection methods (echo sounding, triangulation from ice) for different lakes.

Limitations

• Last updated 1999-03-15 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
