Osama Bin Laden - Burial At Sea

It's completely appropriate that the U.S. dumped Osama Bin Laden's body in the ocean. The last thing anyone needs is an Osama Bin Laden grave where people would sell t-shirts and hatch more horrible plots. And I'm sure people would try to dig him up and take him god knows where. But what I find odd about the whole "burial at sea" is the use of the word "burial." How can you be "buried" in the water? Shouldn't it be called "dump in the sea" or "plop in the sea"?
