Bay of Bengal Index Map
The Bay of Bengal is located east of the Indian subcontinent and west of the Malay Peninsula. India, Bangladesh, and Myanmar border the Bay of Bengal to the north. The latitude and longitude bounds of the area range from 5.0 – 24 degrees north and 78 – 101 degrees east respectively. The areal extent is approximately 5,220,000 square kilometers (2,015,500 sq. miles).
Bay of Bengal IGC 3D Earth Model Bouguer Gravity
The Bouguer Gravity Anomaly Map was generated using Sandwell’s Free-Air Gravity grid version 28.1 and Sandwell’s bathymetry/topography grid version 19.1. The Bouguer corrections for offshore and onshore areas were done using a density of 2.3 g/cc and a density of 2.67 g/cc respectively. The objective of the Bouguer correction is to minimize the effect of high relief bathymetric features observed in the Free-air gravity offshore data, similarly to correct for the excess of gravity effects due to topography above sea level onshore. The resulting Bouguer Gravity Anomaly Map is recommended for qualitative interpretation of tectonic elements and crustal structure. The Map ranges between -165 and 229 milligals and contoured at 5 mGals.
