Participation to the Indian Ocean Geoid Low Expedition
A journey of seismological inquisitiveness into the depths of the Indian Ocean with ORV Sagar-Kanya. The Indian Ocean in the Southern Hemisphere: "Painting the sky" The start – Expedition SK-348 The journey starts with a broad vision of the Indian Ocean Geoid Low (IOGL)- Programme, initiated by NCPOR, MoES, to understand the origin of the lowest geoid existing on the Earth. The lowest geoid appears to be a dent on Earth’s surface created due to low-density material lying beneath the Indian Ocean. Various theories have been put forth to explain its existence, of which a brief outlook can be viewed in Ningthoujam et al., (2019). In May 2018, an array of 17 Ocean Bottom Seismometers (OBSs) was deployed in the Indian Ocean for 2 years to resolve and provide a scientific explanation to the IOGL. Unfortunately, I missed the initial journey. Phase I- Recovery and Re-deployment – SK-360 A great success with 10...
