Ukraine - November 25th, 2011

Crimea, is a sub-national unit, an autonomous republic, of Ukraine. It is located on the northern coast of the Black Sea (blue, below) and on the western coast of the Sea of Azov (green, upper right), on the Crimean Peninsula, bordering Kherson Oblast from the North. Crimea’s total land area is 26,100 km2 (10,077 sq mi).

Crimea is connected to the mainland by the 5–7 kilometres (3.1–4.3 mi) wide Isthmus of Perekop. However, it is almost cut off from the mainland by the Sivash Sea, actually a large system of shallow, silty lagoons. Here, the lagoons show varied, bright colors, ranging from lime green to electric blue to pink.

At the eastern tip of Crimea is the Kerch Peninsula, which is directly opposite the Taman Peninsula on the Russian mainland. Between the Kerch and Taman peninsulas, lies the 3–13 kilometres (1.9–8.1 mi) wide Strait of Kerch, which connects the waters of the Black Sea with the Sea of Azov.

The Crimean coastline is broken by several bays and harbors. The southeast coast is flanked at a distance of 8–12 kilometres (5.0–7.5 mi) from the sea by a parallel range of mountains, the Crimean Mountains. These mountains are backed by secondary parallel ranges. Seventy-five percent of the remaining area of Crimea consists of semiarid prairie lands, a southward continuation of the Pontic steppes, which slope gently to the northwest from the foot of the Crimean Mountains.

Black Sea - August 16th, 2009

Black Sea - August 16th, 2009

The Dnieper River flows across Ukraine, first southeast then southwest, into the Black Sea. Further southwest along the shoreline, the mouth and delta of the Danube River can also be seen.

On the right, in Russia, the Don River spills through Taganrog Bay into the  Sea of Azov , which is in turn connected to the Black Sea through the Strait of Kerch.

Lying in the north central part of the Black Sea is the Crimean Peninsula, whose connection to the Ukrainian mainland via the Isthmus of Perekop is punctuated by the salty, marshy inlets of the Sivash Sea.

Both the Danube and the Dnieper can be seen releasing  some sediments into the Black Sea, although the concentration appears to heavier in the Sea of Azov near the mouth of the Don.

Border between Ukraine and Crimea - November 28th, 2008

This image shows us the border between Ukraine and Crimea, a peninsula.

Crimea is connected to the mainland of Ukraine by the 5–7 kilometre (3–4 mile) wide Isthmus of Perekop, visible on the left although slightly obscured by clouds.

To the West we can see the Bay of Karkinit in the Black Sea, while the Sea of Azov is visible to the East.

The waters between the Sea of Azov and the Isthmus of Perekop appear more shallow and filled with sediments, making the water a greenish-tan color.

This area is known as the Sivash Sea, or Putrid Sea. It is a salt lagoon, about 1,000 sq mi (2,590 sq km),  extending along the northeastern coast of Crimea.

It is separated—except at the Genichesk Strait—from the Sea of Azov by the Arabat Tongue, a narrow sandspit circa 70 mi (110 km) long; the Perekop Isthmus separates it from the Black Sea in the north.

The sea is a complex system of shallow inlets, straits, and sandbars. The water, which has a salt content of up to 20%, has been the source of table salt and of several chemicals, including bromine.
