Deciphering Earth’s largest geoid anomaly: The Indian Ocean Geoid Low

 

Anomalous features on the Earth provide important clues towards deciphering its interior. Global geoid modelling suggests a remarkable deficit  of about (-)106 m in the geoid height in the Indian Ocean, which is often referred to as the Indian Ocean Geoid Low (IOGL).


 The scientific research program entitled “Exploring the Origin of Indian Ocean Geoid Low” aims to investigate potential reasons behind this one of the most intriguing anomalies. The Ministry of Earth Science [MoES], Government of India has entrusted this scientific mandate to explore the largest geoid low anomaly to the National Centre for Polar and Ocean Research [NCPOR] as the nodal agency. The geosciences division at NCPOR is responsible for planning, coordination and implementation of this program through long term scientific observations in the Indian Ocean.
