Topographic Map of Signy Island, showing contours, spot heights, locations of huts, routes and ice cap travel area. Projection: Lambert Conformal Conic, standard parallels at 60°41’S and 60°44’S, central meridian at 45°38’W, horizontal datum: WGS84. Vertical datum: Mean Sea Level (MSL) at Signy Research Station. MSL as defined by the tide gauge at the station. To transform data from WGS84 to Signy MSL, apply a local correction factor of -32.235 m (MSL is below WGS84).
