Frank, NOAA water temperature data shows current temps in Long Island Sound running about 5 degrees Fahrenheit below average. That delta is running true right along the New England coast to at least mid coast Maine. I do not know the temp band the larvae needs, but a delta of -5 degrees F is not inconsiderable for a marine biome.

The plankton (barnacle larvae) blooms seem to definitely be dependent on water temperature ( my experience). So with the icy cold winter, the sea water surface temperature is no doubt lagging lower than normal.
But where are all the Bonaparte's (and Ring-billed) Gulls now?  An eBird search might provide some clues. Likewise for Northern Gannets.
