The Tyuleniy Archipelago (Kazakh: Түлен аралдарыTülen araldary, Russian: Тюленьи острова), is an island group in the north-eastern Caspian Sea off the Mangyshlak Bay west of the Mangyshlak Peninsula and about 13 kilometres (8.1 miles) northwest of the Tupkaragan Peninsula, 27 kilometres (17 miles) north of Bautino. Perhaps the most substantial group of islands in the Caspian, they were first accurately mapped by Fedor Ivanovich Soimonov who led the 1719 Caspian Expedition, studying the Caspian Sea from 1719 to 1727.[1]
This article is about the island group in the Caspian Sea. For other similarly named islands, see Tyuleny Island.
Administratively, the Tyuleniy Archipelago belongs to the Mangystau Region of Kazakhstan.[citation needed] It was named "Tyuleniy" —meaning "seal"— after the currently endangered Caspian seal.[2]
Islands
Kulaly Island (Kulaly-Aral) is the westernmost and longest island, stretching 25km (16mi) from tip to tip. Its shape is slightly irregular, with inlets and headlands. There is a meteorological station with a lighthouse and a Kazakh border guard post on this island, making it the only one in the group inhabited by man. The terrain on Kulaly is either arid or waterlogged and reed-covered.[3]
Morskoy Island (Morskoy Aral) is the next island and the second largest island. It is also the biggest in area, with a length of 19km (12mi) and a maximum width of 7km (4.3mi). This island consists mostly of wetland.
Rybachy Island (formerly Ostrov Svyatoy) is long and narrow and is south of Morskoy.
Novyy Island is the easternmost island. It is between Podgorny and the mainland and used to have an irregular shape until about 2009. Recent pictures show that this island has eroded heavily.[citation needed]
Ecology
The islands are desert-like and sandy, with little grass. There are reeds on the leeward side of Kulaly as well as on the other islands, which are much lower and waterlogged. In past centuries many Caspian seals come to the islands' shores, hence the name of the group.
The islands have been declared an Important Bird Area and a National Protected Zone (State Reservation). There are large concentrations of seagulls and wetland birds, like coots, wild ducks, swans, egrets, and waders in the archipelago during their nesting period. The Tyuleniy island group is also an important breeding ground for the Sandwich tern (Sterna sandvicensis).
