"Dawn, and Sunset, and the Colours of the Earth", Michael F. Flynn

NT ASFM (Asimov's Science Fiction) October/November 2006 – science fiction
One morning a ferry heading from Seattle to Bremerton mysteriously vanishes into the fog with nearly a thousand people aboard. No wreckage is found and eyewitnesses and radar report anomalous circumstances at the time of the ferry's disappearance. This story tells how some people are affected by this tragedy and what scientists determine happened.

This is an interesting, readable novelette. I could have done with more admirable bereaved folks and less about adultery, though. I particularly liked the viewpoints of the fisherman and The Adventure Club and the realistically kooky Internet postings.
