The Suez Canal, Egypt
Despite some cloud cover near its two ends, the Suez Canal, in Egypt, can be seen running from top to bottom in this full resolution image.
The canal, opened in 1869, connects the Mediterranean Sea (top) and the Red Sea (bottom) so that water transportation can be affected between Europe and Asia without navigating around Africa or carrying goods overland.
The canal is 193 km (120 mi) long. It is single-lane with 4 passing places north and south of the Great Bitter Lake (center). It contains no locks; seawater flows freely through the canal into the Great Bitter Lake from both the Red Sea in the south and the Mediterranean in the north, replacing evaporation.
A green algal bloom can be seen along the shoreline around Port Said (the northern terminus of the canal), as well as in the Great Bitter Lake.
The southern terminus in the Gulf of Suez, in the Red Sea, appears to have less algae, although this is difficult to discern due to the partial cloud cover.
