Sound (geography)

In geography, a sound is a smaller body of water typically connected to a larger sea or ocean. There is little consistency in the use of "sound" in English-language place names. It can refer to an inlet, deeper than a bight and wider than a fjord, or a narrow sea or ocean channel between two bodies of land (similar to a strait), or it can refer to the lagoon located between a barrier island and the mainland.

Overview

A sound is often formed by the seas flooding a river valley. This produces a long inlet where the sloping valley hillsides descend to sea-level and continue beneath the water to form a sloping sea floor. The Marlborough Sounds in New Zealand are good examples of this type of formation.

Sometimes a sound is produced by a glacier carving out a valley on a coast then receding, or the sea invading a glacier valley. The glacier produces a sound that often has steep, near vertical sides that extend deep underwater. The sea floor is often flat and deeper at the landward end than the seaward end, due to glacial moraine deposits. This type of sound is more properly termed a fjord (or fiord). The sounds in Fiordland, New Zealand, have been formed this way.

A sound generally connotes a protected anchorage. It can be part of most large islands.

In the more general northern European usage, a sound is a strait or the narrowest part of a strait. In Scandinavia and around the Baltic Sea, there are more than a hundred straits named ''Sund'', mostly named for the island they separate from the continent or a larger island.

In contrast, ''the'' Sound is the common international

In areas explored by the British in the late 18th Century, particularly the northwest coast of North America, the term "sound" was applied to inlets containing large islands, such as Howe Sound in Vancouver and Puget Sound in Washington State. It was also applied to bodies of open water not fully open to the ocean, such as Caamaño Sound or Queen Charlotte Sound in Canada, or broadenings or mergings at the openings of inlets, like Cross Sound in Alaska and Fitz Hugh Sound in British Columbia.

Along the east coast and Gulf Coast of the United States, a number of bodies of water that separate islands from the mainland are called "sounds". Long Island Sound separates Long Island from the eastern shores of the Bronx, Westchester County, and southern Connecticut. Similarly, in North Carolina, a number of large lagoons lie between the mainland and its barrier beaches, the Outer Banks. These include Pamlico Sound, Albemarle Sound, Bogue Sound, and several others. The Mississippi Sound separates the Gulf of Mexico from the mainland, along much of the gulf coasts of Alabama and Mississippi.

Etymology

The term sound is derived from the Anglo-Saxon or Old Norse word ''sund'', which also means " swimming".

The word ''sund'' is already documented in Old Norse and Old English as meaning "gap" (or "narrow access"). This suggests a relation to verbs meaning "to separate", such as ''absondern'' and ''aussondern'' (German), ''söndra'' (Swedish), ''sondre'' ( Norwegian), as well as the English noun ''sin'', German ''Sünde'' ("apart from God's law"), and Swedish ''synd''. English has also the adjective "asunder" and the noun "sundry', and Swedish has the adjective ''sönder'' ("broken").

In Swedish and in both Norwegian languages, "sund" is the general term for any strait. In Swedish and Nynorsk, it is even part of names worldwide, such as in Swedish "Berings sund" and "Gibraltar sund", and in Nynorsk "Beringsundet" and "Gibraltarsundet". In German "Sund" is mainly used for place names at the Baltic Sea like Fehmarnsund, Strelasund, and Stralsund.
