I am working in a project related to coastal zone of Odisha state, India. For that I need bathymetry data. I am interested in bathymetry data of coastal are, about 5-6 kilometers from the coast line.
You can get the bathymetric data from emodnet (https://www.emodnet-bathymetry.eu/) or GEBCO (https://www.gebco.net/data_and_products/gridded_bathymetry_data/)
