Seasonal Changes in Sediments in Lake Van, Turkey

38.6N 42.9E

April 29th, 2013 Category: Lakes, Sediments

Turkey – April 28th, 2013

The varved sediments (the layer or series of layers of sediment deposited in a body of still water in one year) of Lake Van (the greyish white salt lake in the upper right quadrant), in Turkey, provide a high-quality continental archive of seasonal to decadal-scale climate variability. Remotely-sensed total suspended-matter concentrations, validated by contemporaneous water-column sampling, show great temporal and lateral variations (whitings and turbidity plumes).

From 2006 to 2009, sequential sediment traps recorded high particle fluxes during spring and fall, medium fluxes during summer, and almost zero flux during winter. Some fluxes are controlled by river discharge (precipitation and snowmelt) during spring, by high productivity during summer, and by river discharge (precipitation before snowfall starts) and mixing during fall (click here for more information).

Plume of Dust Sweeping from Egypt Across Cyprus – April 10th, 2013

Egypt – April 8th, 2013

A plume of dust sweeps over the coast of Egypt, veiling the Nile Delta and the Sinai Peninsula, and northwards over the Mediterranean Sea, over and past Cyprus to Turkey (visible at the top of the full image). Middle Eastern countries on the east coast of the sea, such as Israel, are also being affected. More frequent dust storms are a sign of desertification and climate change.

Dust Over Mediterranean Sea and Turkey

Egypt – April 3rd, 2013

Days after an intense dust storm that blasted sand and other particles over northern Egypt, the Mediterranean Sea and the Middle East (click here for previous images), a veil of dust continues to hang over the region. Here, dust can be seen over the Mediterranean and, in the full image, reaching northeastward up to Turkey.

Dust Framing Eastern Shore of Mediterraean Sea

Eastern Mediterranean – April 1st, 2013

While the end of March saw a large dust storm blowing off the coast of Libya and over the Mediterranean (click here for previous image), the beginning of April saw a different thick dust plume covering the Mediterranean, this type from Egypt. Here, the dust can be seen blowing over the eastern part of the Nile Delta and the Sinai Peninsula before following the curve of the eastern shore of the Mediterranean, by countries such as Israel, Lebanon, Syria and Turkey, before being pushed back towards Egypt once again.

Borders Feature Revealing Lakes Near Turkey

Iran, Turkey, Armenia – January 27th, 2013

This cloud-covered image highlights the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature, which overlays countries’ boundaries on satellite images. Here, Iran, Turkey, Georgia, Russia and Azerbaijan can be observed counterclockwise from the bottom right, with Armenia in the center. While Lake Van, in Turkey, is partially visible through the clouds, the borders feature shows the location of other lakes that would be hidden: Lake Urmia (bottom), in Iran, Lake Sevan (center), in Armenia, and the Mingachevir Reservoir (upper right), in Azerbaijan.
