Hans Tausen Ice Cap (Danish : Hans Tausens Iskappe) is an ice cap in Peary Land, northern Greenland. Administratively it is part of the Northeast Greenland National Park. [2]

Contents

Age

Ice cores show it is around 3500–4000 years old. It formed since the Holocene climatic optimum of 6000-8000 BP. [3] [4] [5] [6] [7] It is a well studied ice cap, and is important to understanding the Holocene climatic optimum. [8]

Geography

The ice cap is located south of Amundsen Land and the Nordpasset, at the western end of the De Long Fjord area, east of Freuchen Land across the inner J.P. Koch Fjord, west of Odin Fjord and south of the O.B. Bøggild Fjord. [9] It is about 100 km (62 mi) from north to south and 80 km (50 mi) from east to west and sits on a 1,300 m (4,300 ft) high plateau.

The Hans Tausen Ice Cap is the source of many glaciers, including the Ymer Glacier to the east, the Aajaku Glacier, Inukitsaq Glacier and Persuaq Glacier to the west, and the Lur Glacier and Tjalfe Glacier to the north. [10] [2]

The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the timespan of the Late Pleistocene.

The Holocene Climate Optimum (HCO) was a warm period in the first half of the Holocene epoch, that occurred in the interval roughly 9,500 to 5,500 years BP, with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene Optimum, Holocene Thermal Maximum, Holocene global thermal maximum, Hypsithermal, and Mid-Holocene Warm Period.

In 1988, the project was accepted as an ESF-associated program, and the fieldwork was started in Greenland in the summer of 1989.

Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean.

<span class="mw-page-title-main">Quaternary glaciation</span> Series of alternating glacial and interglacial periods

The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma and is ongoing. Although geologists describe this entire period up to the present as an "ice age", in popular culture this term usually refers to the most recent glacial period, or to the Pleistocene epoch in general. Since Earth still has polar ice sheets, geologists consider the Quaternary glaciation to be ongoing, though currently in an interglacial period.
