The findings support earlier studies by the trio of researchers that linked specific sites on the peninsula to locations mentioned in Homer's verses.
A borehole drilled through the suspected site of the channel and underwater imaging of nearby bays have revealed rubble and marine fossils consistent with the researchers' theory, said John Underhill, a geologist at the University of Edinburgh.
"This is a prima facie indication that we were right that there was a channel there, subsequently filled by infall and seismic disturbances," he said.
The web site for the project is here. There's not a whole lot at the site, though there are some pics of the borehole and the island.
