The values of gravity disturbances Δg (mGal) for the whole Antarctica. The Wilkes Land (WL) anomaly (between longitudes 100 and 130°E, geodetic latitudes 60 and 75°S) is clearly visible as a semicircular feature with positive anomaly in its center and flanking negative semiring anomaly around, namely from southern directions.
