A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean , a lake , or another bay. A large bay is usually called a gulf , sea , sound , or bight . A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. The term embayment is also used for related features , such as extinct bays or freshwater environments.
9-596: Bridger Bay ( 60°33′S 45°51′W / 60.550°S 45.850°W / -60.550; -45.850 ) is a semi-circular bay 2.5 nautical miles (5 km) wide, lying west of Tickell Head along the north coast of Coronation Island , in the South Orkney Islands . It was discovered in 1821 in the course of the joint cruise by Captain Nathaniel Palmer , an American sealer, and Captain George Powell ,
18-401: A head , is a coastal landform , a point of land usually high and often with a sheer drop, that extends into a body of water . It is a type of promontory . A headland of considerable size often is called a cape . Headlands are characterised by high, breaking waves , rocky shores , intense erosion , and steep sea cliff . Headlands and bays are often found on the same coastline. A bay
27-628: A British sealer. It was surveyed by the Falkland Islands Dependencies Survey in 1956–58 and named by the UK Antarctic Place-Names Committee for John F.D. Bridger , who participated in the survey of Coronation Island and Signy Island . [REDACTED] This article incorporates public domain material from "Bridger Bay" . Geographic Names Information System .

36-441: A bay often reduces the strength of winds and blocks waves . Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches , which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace". Bays were significant in the history of human settlement because they provided easy access to marine resources like fisheries . Later they were important in
45-453: A bay unless its area is as large as (or larger than) that of the semi-circle whose diameter is a line drawn across the mouth of that indentation — otherwise it would be referred to as a bight . There are various ways in which bays can form. The largest bays have developed through plate tectonics . As the super-continent Pangaea broke up along curved and indented fault lines, the continents moved apart and left large bays; these include
54-573: Is a stub . You can help Misplaced Pages by expanding it . Bay A bay can be the estuary of a river, such as the Chesapeake Bay , an estuary of the Susquehanna River . Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada . Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology . The land surrounding
63-405: Is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays ) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk , limestone , and granite ) forming
72-501: The Gulf of Guinea , the Gulf of Mexico , and the Bay of Bengal , which is the world's largest bay. Bays also form through coastal erosion by rivers and glaciers . A bay formed by a glacier is a fjord . Rias are created by rivers and are characterised by more gradual slopes. Deposits of softer rocks erode more rapidly, forming bays, while harder rocks erode less quickly, leaving headlands . Headland A headland , also known as
81-521: The development of sea trade as the safe anchorage they provide encouraged their selection as ports . The United Nations Convention on the Law of the Sea defines a bay as a well-marked indentation in the coastline, whose penetration is in such proportion to the width of its mouth as to contain land-locked waters and constitute more than a mere curvature of the coast. An indentation, however, shall not be regarded as
