a Bathymetry map of the study area as derived from swath bathymetric data acquired using Multibeam SB 3012 system. The ensonified features—Laxmi Ridge, Raman Seamount and submarine channels (1, 2, 3, 4A, 4B) have been marked. Contours represent depth ranging 2100–3900 m BMSL (Below Mean Sea Level) at an interval of 100 m; Seismic tracks IODP-04 and IODP-07 used in this study are also marked. Segments AA′, BB′ and CC′ are elaborated in Figs. 3c, 4 and 5 respectively. b 3D visualization of Channel 1 flowing in between the northern reaches of Laxmi Ridge is provided here. Vantage point is WSW–ENE. Vertical exaggeration is increased to 5× in order to highlight the south-ward deepening trend followed by Channel 1. Channel 2 and 3 can also be lightly identified towards NE of Channel 1
