A skerry is a small rocky island, or islet, usually too small for human habitation. It may simply be a rocky reef. A skerry can also be called a low sea stack.[1]

A skerry may have vegetative life such as moss and small, hardy grasses. They are often used as resting places by animals such as seals and birds.

Etymology

The term skerry is derived from the

Scandinavian languages' words for skerryIcelandic, Faroese: sker, Danish: skær, Swedish: skär, Norwegian: skjær / skjer, found also in German: Schäre, Finnish: kari, Estonian: skäär, Latvian: šēra, Lithuanian: Šcheras and Russian: шхеры (shkhery). In Scottish Gaelic, it appears as sgeir, e.g. Sula Sgeir, in Irish as sceir, in Welsh as sgeri, and in Manx
as skeyr.

Formation

Skerries are most commonly formed at the outlet of

valleys at right angles to the coast join with other cross valleys in a complex array. In some places near the seaward margins of fjorded areas, the ice-scoured channels are so numerous and varied in direction that the rocky coast is divided into thousands of island blocks, some large and mountainous, while others are merely rocky points or rock reefs
that menace navigation.

The island fringe of Norway is such a group of glacially formed skerries, called a skjærgård (sometimes translated into English as archipelago, but specifically one near the coast of the mainland). Many of the cross fjords are so arranged that they parallel the coast and provide a protected channel behind an almost unbroken succession of rocky islands and skerries. By this channel one can travel through a protected passage almost the entire 1,600 km (1,000 mi) route from

North Cape, Norway. The Blindleia is a skerry-protected waterway that starts near Kristiansand in southern Norway and continues past Lillesand

north for 800 km (500 mi) along the west coast of the South American continent.

The southwestern coast of Finland also has a great many skerries; so many, in fact, that they form an archipelago. This area is experiencing post-glacial rebound that connects the rising islands as they break sea level, revealing till deposits and eventually clay bottoms. The skerries exist as small rocky islands before uplift of adjacent terrain changes the classification of this landform into a tombolo.[3]

In the

Russian Federation, the best examples are the Minina Skerries, located in the Kara Sea, in the western shores of the Taymyr Peninsula, and the Sumsky Skerries, located in the White Sea
.

The United Kingdom has a large number of skerries including Staple Island (an outer Farne Island) in England; a small rocky outcrop near the Fowlsheugh in northeast Scotland; numerous reefs in the Hebrides such as Dubh Artach and Skerryvore; and The Skerries, located off the Antrim coast of Northern Ireland.

Skerries is the name of a coastal area of Dublin, Ireland, with many skerries offshore, including Rockabill, Shenick Island, Colt Island and St Patrick's Island.
