Ocean survival simulator

you were sitting in a boat, specifically one of those military grade ones, then I out of nowhere some laser shot through the hull, you got in a emergency lifepod and sunk to the ocean reef floor as you saw the ship above you explode and crumble, what will you do next? (lifepod ai : location, grand reef, depth : 21 meters, equivalent is 68 feet, cause of ship obstruction : unknown.)
