Islands like ice bergs

Jenny walks along the perimeter of the new little island.

When I was here sometime in the early nineties the island stretched
long and narrow.

A visit in the mid nineties found the island breached in the middle,
with a sand bar and two sandy beaches reaching out to each other
across the widening gulf.

Today's visit finds three islands, with no trace of the connecting
sand bar, and just a few small sand beaches.

Do islands calve like ice bergs?

If you're in the Chesapeake Bay, then yes, islands calve like icebergs. The reasons being some unknown mixture of 1) sea level rise, 2) increase of large boat wake occurence, and 3) loss of seagrass (to attenuate wave action) after Hurricane Agnes in 1972. Bay grasses are back to only about 10-15% of their pre-Agnes extent.
