The six-kilometer-wide Strait of
Tiran (also called the Straits of Tiran) between the Egyptian mainland
and Tiran Island separates the Gulf of Aqaba from the Red Sea. It
provides two channels (290 meters and 73 meters deep, respectively)
navigable by large ships bound for ports in Jordan and Israel; there is
also a smaller passage between the east side of Tiran Island and Saudi
Arabia, but this single channel is 16 meters deep. Due to its strategic
location, control of the Strait has been an important factor in
historical conflicts in the region, including the Suez Crisis in 1956
and the Six-Day War in 1967.
This photograph taken by an astronaut on the International Space
Station (ISS) illustrates the morphology of the Strait. The relatively
clear, deep-water passages of the western Strait of Tiran are visible at
image left, while the more sinuous, shallow-water passage on the Saudi
Arabia side can be seen at image top center. Light blue to turquoise
areas around Tiran Island indicate shallow water, while the island
itself is arid and largely free of vegetation. Coral reefs are also
found in the strait and are a popular diving destination.
The silvery sheen on the water surface within the Strait and the
south of Tiran Island is sunglint—light reflecting off the water surface
back towards the observer on the ISS. Disturbances to the surface, as
well as presence of substances such as oils and surfactants, can change
the reflective properties of the water surface and highlight both
surface waves and subsurface currents. For example, a large wave set is
highlighted by sunglint at image lower right.
Astronaut photograph ISS036-E-10628
was acquired on June 23, 2013, with a Nikon D3S digital camera using a
400 millimeter lens, and is provided by the ISS Crew Earth Observations
experiment and Image Science & Analysis Laboratory, Johnson Space
Center. The image was taken by the Expedition 36 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab
to help astronauts take pictures of Earth that will be of the greatest
value to scientists and the public, and to make those images freely
available on the Internet. Additional images taken by astronauts and
cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by William L. Stefanov, Jacobs/JETS, both at NASA-JSC.
