Information: - A bay is a body of water connected to an ocean or lake, formed by an indentation of the shoreline. A large bay may be called a "gulf", a "sea", a "sound", or a "bight". A "cove" is a smaller circular or oval coastal inlet with a narrow entrance; some coves may be referred to as bays. A "fjord" is a particularly steep bay shaped by glacial activity. - Graae Glacier is a glacier long on the north side of Mount Sabatier, flowing west-southwest to Trollhul in the south part of South Georgia. It was surveyed by the South Georgia Survey (SGS) in the period 195157, and named by the UK Antarctic Place-Names Committee for Morgens E.W. Graae of Denmark, who developed sledges for the SGS, 195354 and 195556. - An inlet is an indentation of a shoreline, usually long and narrow, such as a small bay or arm, that often leads to an enclosed body of salt water, such as a sound, bay, lagoon, or marsh. In sea coasts, an inlet usually refers to the actual connection between a bay and the ocean and is often called an "entrance" or a recession in the shore of a sea, lake, or river. A certain kind of inlet created by glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes. - Mount Sabatier is a mountain 1,145 m, standing close north of Mount Senderens and 1 mile (1.6km) northeast of Paradise Beach in the south part of South Georgia. The feature appears on charts dating back to the 1930s. It was surveyed by the SGS in the period 1951-57, and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Professor Paul Sabatier (1854-1941), French chemist, whose work with Jean-Baptiste Senderens led to the introduction in about 1907 of the hydrogenation process for hardening whale oil. - A cove is a small type of bay or coastal inlet. Coves usually have narrow, restricted entrances, are often circular or oval, and are often situated within a larger bay. Small, narrow, sheltered bays, inlets, creeks, or recesses in a coast are often considered coves. Colloquially, the term can be used to describe a sheltered bay. Geomorphology describes coves as precipitously-walled and rounded cirque-like openings as in a valley extending into or down a mountainside, or in a hollow or nook of a cliff or steep mountainside. - Geomorphology (from Ancient Greek: , "ge", "earth"; , "morph", "form"; and , "logos", "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. - A coastline or a seashore is the area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake. A precise line that can be called a coastline cannot be determined due to the Coastline paradox. - A glacier (or ) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. - Denmark is a Scandinavian country in Europe. The southernmost and smallest of the Nordic countries, it is south-west of Sweden and south of Norway, and bordered to the south by Germany. The Kingdom of Denmark is the sovereign state that comprises Denmark proper and two autonomous constituent countries in the North Atlantic Ocean: the Faroe Islands and Greenland. Denmark has a total area of , and a population of 5.7million. The country consists of a peninsula, Jutland, and an archipelago of 443 named islands, with the largest being Zealand and Funen. The islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate. - Trollhul is a small cove 4 nautical miles ( 7 km ) northwest of Cape Disappointment at the mouth of Graae Glacier , along the south coast of South Georgia . Trollhul was surveyed by the South Georgia Survey in the period 1951 - 57 . The name is well established in local use . The name is Norwegian and means '' troll hollow '' . This article incorporates public domain material from the United States Geological Survey document '' Trollhul '' ( content from the Geographic Names Information System ) . - The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are published in the international Composite Gazetteer of Antarctica maintained by SCAR, too. What entity does 'trollhul' has the relation 'instance of' with?
Answer:
bay
