There has to be some connection to the salt water. Even a small number of stub radials would work. I've found that radials often work better than a ground rod for RF. A deep ground rod is good for lightning ground, however. Bear in mind that the tower of an AM station is only half the antenna. The radials comprise the other half. A buried half a dipole, sorta. One of my clients just had a 170-200 foot well casing driven in next to the tower for lightning ground. It's an FM, so there was no need for radials. Many high voltage power distribution towers around here use four 150' +/- lengths of #8 copperweld wire for lightning ground. So, both can be effective.
