ship deployed its side scan sonar, to take a picture of the bottom of the sea. One of the images obtained was of a large silt-covered hump on the seabed. This was located below the sea surface and close to Khukris last reported position. Jamunas magnetometer also confirmed the presence of steel inside this hump. The object was nearly long, had a north-east-southwest orientation and seemed to be sitting on its keel with its mast sticking out of the silt, confirming that it was the sunken ship. Survey work In 2013, INS Jamuna conducted a hydrographic survey off the Kenya coastline on the request of the Kenyan government to survey Manda Bay and Kiwaiyu Bay. Subsequently, the "first updated navigational charts" of the areas were presented to Kenyan authorities in 2014 by the Chief of the Naval Staff, Admiral RK Dhowan. The ship also conducted a hydrographic survey off the Dar es Salaam port in Tanzania.
