Humboldt Glacier
Humboldt Glacier () is one of the major glaciers in northern Greenland. The glacier is named after German naturalist Alexander von Humboldt and is the widest tidewater glacier in the Northern Hemisphere. Geography The Humboldt Glacier borders the Kane Basin in North West Greenland. Its front is wide. It has been retreating in the period of observation spanning 1975–2010. Humboldt Glacier fringes the coast of Peabody Bay from north to south. The McGary Islands lie off the glacier at the southern end of the bay.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute'', p. 88 See also *List of glaciers in Greenland *Peabody Bay Peabody Bay () is a large bay in northwestern Greenland.

Tidewater Glacier
The tidewater glacier cycle is the typically centuries-long behavior of tidewater glaciers that consists of recurring periods of advance alternating with rapid retreat and punctuated by periods of stability. During portions of its cycle, a tidewater glacier is relatively insensitive to climate change. Calving rate of tidewater glaciers While climate is the main factor affecting the behavior of all glaciers, additional factors affect calving (iceberg-producing) tidewater glaciers. These glaciers terminate abruptly at the ocean interface, with large pieces of the glacier fracturing and separating, or calving, from the ice front as icebergs. Climate change causes a shift in the equilibrium line altitude (ELA) of a glacier. This is the imaginary line on a glacier, above which snow accumulates faster than it ablates, and below which, the reverse is the case. This altitude shift, in turn, prompts a retreat or advance of the terminus toward a new steady-state position. However, this ch ...

Greenland
Greenland is an autonomous territory in the Danish Realm, Kingdom of Denmark. It is by far the largest geographically of three constituent parts of the kingdom; the other two are metropolitan Denmark and the Faroe Islands.

Greenland is one of the Special territories of members of the European Economic Area#Overseas countries and territories, Overseas Countries and Territories of the European Union and is part of the Council of Europe. It is the List of islands by area, world's largest island, and lies between the Arctic Ocean, Arctic and Atlantic oceans, east of the Arctic Archipelago, Canadian Arctic Archipelago. It is the location of the northernmost point of land in the world; Kaffeklubben Island off the northern coast is the world's Northernmost point of land, northernmost undisputed point of land—Cape Morris Jesup on the mainland was thought to ...

Kane Basin
Kane Basin (; ) is an Arctic waterway lying between Greenland and Ellesmere Island, Canada's northernmost. It links Smith Sound to Kennedy Channel and forms part of Nares Strait. It is approximately in length and at its widest. It is named after the American explorer Elisha Kent Kane, whose expedition in search of Franklin's lost expedition crossed it in 1854. Kane himself had named it "Peabody Bay," in honor of philanthropist George Peabody, the major funder of Kane's expedition. Currently Peabody Bay is a bay at the eastern side of the basin, off the southwestern end of the Humboldt Glacier Humboldt Glacier () is one of the major glaciers in northern Greenland.

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on ever ...

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 1769 – 6 May 1859) was a German polymath, geographer, natural history, naturalist, List of explorers, explorer, and proponent of Romanticism, Romantic philosophy and Romanticism in science, science. He was the younger brother of the Prussian minister, philosopher, and linguistics, linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botany, botanical geography laid the foundation for the field of biogeography, while his advocacy of long-term systematic geophysical measurement pioneered modern Earth's magnetic field, geomagnetic and meteorology, meteorological monitoring. Humboldt and Carl Ritter are both regarded as the founders of modern geography as they established it as an independent scientific discipline. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a non-Spanish European scientific point of view. His des ...

Operational Navigation Chart B-8, 3rd Edition
An operational definition specifies concrete, replicable procedures designed to represent a construct. In the words of American psychologist S.S. Stevens (1935), "An operation is the performance which we execute in order to make known a concept." For example, an operational definition of "fear" (the construct) often includes measurable physiologic responses that occur in response to a perceived threat. Thus, "fear" might be operationally defined as specified changes in heart rate, electrodermal activity, pupil dilation, and blood pressure. Overview An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct. Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research. Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparatio ...
