View from the International Space Station of the ancient Potidea canal in Greece May 13, 2016. For 2,000 years this canal has connected the Thermaikos and Toronaios Gulfs. Coastal currents and erosion over 2,000 years appear to have displaced the two sides of this isthmus seen in the coastline's misalignment.
