Venice Lagoon
A narrow barrier island protects the Lagoon of Venice from storm waves in the
northern Adriatic Sea, and breakwaters protect inlets to the lagoon. Red tiles
on the roofs of Venice contrast with the grays of the sister city of Mestre, and
the cities are joined by a prominent causeway. What appears to be another
causeway joining the island to the airport (top right) is actually the combined
wakes of many boats and water taxis shuttling between them. Small, bright
agricultural fields on well-drained soils (top left) contrast with the darker
vegetation of back-bay swamps, where fishing is a popular pastime.
The water is turbid in the northern half of the lagoon, the result of heavy
use by watercraft and of dense urban populations on the shores. This turbidity
and other issues of environmental concern led to the creation in 2002 of the
Atlas of the Lagoon (Atlante della laguna), which was set up to
document environmental conditions and to track changes. Today, the Atlante
della laguna is available online (in Italian) and provides a comprehensive
collection of interpretive maps and imagery—including astronaut photographs from
the International Space Station. A detailed view of Venice in 2007 can be viewed
here. A more detailed article on the use of astronaut photography to monitor
environmental change in the Lagoon of Venice
is available here.
This astronaut photograph (ISS039-E-19482) was acquired on May 9, 2014, with
a Nikon D3S digital camera using a 400 millimeter lens, and is provided by the
ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing
Unit, Johnson Space Center. The image was taken by the Expedition 39 crew. It
has been cropped and enhanced to improve contrast, and lens artifacts have been
removed.

NASA, nos recrea con muestra el famoso Lago de Venecia,tomada desde el espacio: Estación Espacial Internacional que a tantos escritores, poetas y gente común han inspirados los famosos canales. el Mar Adriático baña a esta ciudad, pero nunca supe que era un lago..
