Second Thule Expedition
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wulff Land
Wulff Land ( da, Wulffs Land) is a peninsula in far northwestern Greenland. Administratively it is a part of the Northeast Greenland National Park. History Wulff Land was named after Swedish botanist and Arctic explorer Thorild Wulff (1867–1917), who went with Knud Rasmussen on the Second Thule Expedition and died from fatigue near Cape Agassiz in southern Peabody Bay.Mark Nuttall, ''Encyclopedia of the Arctic'', p. 1744 The Wulff Land peninsula is a barren and inhospitable place. Unlike Peary Land to the NE, no remains of human habitation have been found. Geography Wulff Land is located to the northeast of Warming Land and east of Hendrik Island across the Sherard Osborn Fjord. Nares Land lies to the east, across the Victoria Fjord and Stephenson Island to the northeast. Cape May in the Lincoln Sea is its northernmost headland. To the south the peninsula is attached to the mainland and its ice cap. Wulff Land is a largely unglaciated and mountainous peninsula with a lar ...

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are '' Draba'' (440 species), '' Erysimum'' (261 species), '' Lepidium'' (234 species), '' Cardamine'' (233 species), and '' Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as '' Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and co ...

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.

Cape Agassiz (Greenland)
Cape Agassiz is the east tip of Hollick-Kenyon Peninsula, a narrow ice-drowned spur extending east from the main mountain axis of the Antarctic Peninsula between Mobiloil Inlet and Revelle Inlet. The cape is the east end of a line from Cape Jeremy dividing Graham Land and Palmer Land. It was discovered in December 1940 by the United States Antarctic Service who named it for W.L.G. Joerg, a geographer and polar specialist. At his request it was named by the Advisory Committee on Antarctic Names for Louis Agassiz, an internationally famous American naturalist and geologist of Swiss origin, who first propounded the theory of continental glaciation A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate bet ... (Etudes sur les Glaciers, Neuchatel, 1840). Headlands of Palmer Land Headlands o ...

Peary Land
Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean. It reaches from Victoria Fjord in the west to Independence Fjord in the south and southeast, and to the Arctic Ocean in the north, with Cape Morris Jesup, the northernmost point of Greenland's mainland, and Cape Bridgman in the northeast. History Ancient settlements Peary Land was historically inhabited by three separate cultures, during which times the climate was milder than presently: *Independence I culture, Paleo-Eskimo (around 2000 BC, oldest remains dating from 2400 BC) *Independence II culture, Paleo-Eskimo (800 BC to 200 BC) * Thule culture (ancestral to the modern Inuit, around AD 1300) Peary's explorations The area is named after Robert E. Peary, who first explored it during his expedition of 1891 to 1892. Originally, Peary Land was believed to be an island, separated from the main island by the so-called Peary Channel, an assumed connection between Nordenskiöld Fjord and ...
