Adventfjorden in the context of "Longyearbyen"

Isfjorden is the second longest fjord in the Norwegian archipelago of Svalbard. It lies on the west side of Spitsbergen, an island in the Arctic Ocean about midway between Norway and the North Pole, and the largest in the archipelago. The mountain of Alkhornet stands on the northern side of the entrance to the fjord, as does the coastal plain of Daudmannsøyra. A portion of Isfjorden is included in the national parks of Norway as Nordre Isfjorden Land National Park. Around the fjord lie many of the largest settlements in Svalbard: Barentsburg, Longyearbyen (on the Adventfjorden) and Pyramiden.

The Longyear Valley (Norwegian: Longyeardalen) is a valley and ravine in Svalbard. It slightly winds 40 kilometres (25 mi) WNW ending in Adventfjorden, facing west, the broadest inlet of Spitsbergen, the main landmass. It has a few wind gaps to the south and north-east over small glaciers, under which small streams form. It is between mountains Platåberget and Gruvefjellet. The town of Longyearbyen is at its foot, which is named for the American industrialist John Munro Longyear. The Longyear River is, like all the island's rivers, silted from surrounding glaciers.

John Munro Longyear Sr. (April 15, 1850 – May 28, 1922) was an American businessman and noted developer of timber and mineral lands in the Upper Peninsula of Michigan and Minnesota who became the central figure behind the Arctic Coal Company, which surveyed and mined coalfields on Spitsbergen, from 1905 to 1916. This company developed a settlement on Spitsbergen able to accommodate up to around 500 people which became known as Longyear City, now Longyearbyen, adjacent Advent Bay.

Arctic Coal Company was a coal mining company that operated mines at Longyearbyen (then Longyear City) in Svalbard, Norway, between 1906 and 1916.

The American industrialist John Munro Longyear visited Spitsbergen as a tourist in 1901, where he met with an expedition prospecting for coal. He returned to Spitsbergen 1903, where he met Henrik B. Næss in Adventfjorden, who gave him samples and information on coal fields. Along with his associate Frederick Ayer, Longyear bought the Norwegian claims on the west side of Adventfjorden, installed William D. Munroe as general manager, and expanded the claims significantly the following year. In 1906, the Boston-based Arctic Coal Company, with Ayer and Longyear as the main shareholders, started mining in Mine 1a, after having built docks and housing. The company had American administration, but mostly Norwegian laborers, and named the town Longyear City. Coal was transported the 1.2 kilometers (0.75 mi) from the mine to the port using an aerial tramway built by the German company Adolf Bleichert & Co. of Leipzig. In 1913, the company started preliminary work to open Mine 2a. Following financial difficulties during the First World War, the mining operations were bought by Store Norske Spitsbergen Kulkompani, which was incorporated in Oslo on 30 November 1916.
