The Obama house isn’t on the ocean, it is on the Edgartown Great Pond, a salt-water pond protected from the actual ocean by a strip of beach that occasionally is breached when high tide coincides with a low pressure storm system. The pond (indeed, all of Nantucket and Martha’s Vineyard) were formed as glaciers retreated 10,000+ years ago. The land around the pond is gently sloping and none of the houses on the pond are anywhere near extreme high tide.
