Indian Ocean Gravity Hole Could Be Linked With Anncient Ocean

A vast region in the Indian OceanKnown as the “gravity hole,” Has Intrigured Scientists Since Its Discovery in 1948. Sea levels to drop by an astounding 348 face compared to surrounding Regions. Spanning 1.2 Million Square Miles, The Anomaly Has Long Puzzled Geophysicists, Who recently Made Progress in Uncovering Its Origins.

Formation Linked to Prehistoric Ocean Tethys

Research Published In geophysical research letters in 2023 have traced the gravity hole’s formation to events occurring over 100 million years ago. The ancient ocean tethys, which existed between the supercontinents laurasia and gondwana, played a central role. According to Dr. Attreyee Ghosh, Associate Professor at the Indian Institute of Science and the Co-Author of the Study, Fragments of TETHEYS ‘Oceanic Crust Descended Into The Earth’S Lion years ago.

As these fragments Sank Deeper Over Millions of Years, Denser Materials from the African Region of the Mantle was displaced. Simulations Conducted Using 19 Computer Models Sugged that low-consity magma plumes rose to replace the denser material, effectively reduction the mass beeath the Indian Ocean and Creating the Geoid Low.

Verification of Findings Pending

While the study offers a compeling explanation, additional evidence is required to confirm the findings. Earthquake data is being considered to verify the presence of low-density plumes beneth the region. Scientists like Dr. Ghosh Acknowledge the complexity of Earth’s Mantle dynamics, as similar anomals have been observed globally, revaling the intricate processes with the planet’s interior.

Relevance to planetary science

The discovery highlights the broader significance of study subsurface phenomena for Earth and other planets. Similar mantle structures have been observed beneath MarsUnderscoring the University Nature of Geological Processes Shaping Planetary Bodies. This research continues to shd light on the forces that shape earth’s unique topography, with ongoing studies offering a glimpse into the planet’s enigmatic interior.
