About this work
ISS047e115879 (05/13/2016) --- NASA astronaut Jeff Williams captured this image of the ancient Potidea canal in Greece from the International Space Station. For 2,000 years this canal has connected the Thermaikos and Toronaios Gulfs. Williams posted the photograph to his Twitter account May 13, 2016 saying, "Coastal currents and erosion over 2,000 years appear to have displaced the two sides of this isthmus," which may explain the coastline's misalignment".
