Synthetic magnetic anomaly profile computed using Modmag(R1W) with the following input model parameters; top of magnetic source layer is 6.0 km, bottom of magnetic source layer is 6.5 km, remanent inclination = -81.2°, and remanent declination = 0.0°.

Magnetic anomaly identifications were made using new high quality magnetic data in the Bruce Rise area (90°-115°E) collected by Russian Antarctic Expeditions 49 and 50 in 2004-2005. The total magnetic field was recorded in these surveys by a differential magnetometer to 0.01 nT accuracy. New magnetic anomaly identifications were also made for data collected during Geoscience Australia cruises 228 and 229 (S3-S6). Our new identifications were integrated with earlier identifications of Tikku and Cande (R6.
