Humboldt Glacier
Humboldt Glacier ( da, Humboldt Gletscher) 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 ( da, Peabody Bugt) 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 ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Kane Basin
Kane Basin ( da, Kane Bassin; french: Bassin (de) Kane) is an Arctic waterway lying between Greenland and Canada's northernmost island, Ellesmere Island. It links Smith Sound to Kennedy Channel and forms part of Nares Strait. It is approximately 180 kilometres in length and 130 km at its widest. It is named after the American explorer Elisha 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 ( da, Humboldt Gletscher) is one of the major glaciers in northern Greenland.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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 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 every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use ...

Peabody Bay
Peabody Bay ( da, Peabody Bugt) is a large bay in northwestern Greenland. Administratively it is part of Avannaata municipality. Geography Peabody Bay is located on the eastern side of the Kane Basin off the western end of the Humboldt Glacier. Cape Forbes and the Cass Fjord lie at the northern end of the roughly 80 km wide bay. The McGary Islands lie at the southern end of the bay and the Bonsall Islands lie between that end and Dallas Bay to the SW. Elisha Kane —whose Arctic venture in search of the lost Franklin expedition crossed the area in 1854— had named the Kane Basin itself "Peabody Bay," in honor of philanthropist George Peabody George Peabody ( ; February 18, 1795 – November 4, 1869) was an American financier and philanthropist. He is widely regarded as the father of modern philanthropy. Born into a poor family in Massachusetts, Peabody went into business in dry go ..., the major funder of Kane's expedition.

McGary Islands
The McGary Islands is a small coastal island group in Avannaata municipality, off NW Greenland. The islands are named after James McGary of the Second Grinnell Expedition. They are a breeding ground for the common eider The common eider (pronounced ) (''Somateria mollissima''), also called St. Cuthbert's duck or Cuddy's duck, is a large ( in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breed .... Geography The McGary Islands are a cluster of coastal islands, islets and rocks at the southern end of Peabody Bay about 6 km off Cape Agassiz (Greenland), Cape Agassiz and off the southern end of the Humboldt Glacier.

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, galvanic skin response, 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 preparation ...
