Nuup Kangerlua is a 160 km (99.4 mi) long fjord in the Sermersooq municipality in southwestern Greenland. It was formerly known by its colonial name as Godthaab Fjord (Danish: Godthåbsfjorden), Gilbert Sound and Baal's River.
Located by the island's capital, Nuuk, it is the longest fjord on the Labrador Sea coast of Greenland, and one of the longest in the inhabited part of the country.
Nuuk (Greenlandic pronunciation: [nuːk] ; Danish: Nuuk, formerly Godthåb [ˈkʌtˌhɔˀp]) is the capital and most populous city of Greenland, an autonomous territory in the Kingdom of Denmark. Nuuk is the seat of government and the territory's largest cultural and economic center. It is also the seat of government for the Sermersooq municipality. In January 2025, it had a population of 20,113—more than a third of the territory's population—making it one of the smallest capital cities in the world by population.
The city was founded in 1728 by the Danish-Norwegian missionary Hans Egede when he relocated from the earlier Hope Colony (Haabets Koloni), where he had arrived in 1721; the governor Claus Paarss was part of the relocation. The new colony was placed at the Inuit settlement of Nûk and named Godthaab ("Good Hope"). "Nuuk" is the Greenlandic word for "cape" and is commonly found in Greenlandic place names. It is so named because of its position at the end of the Nuup Kangerlua fjord on the Labrador Sea's eastern shore. Its latitude, at 64°11' N, makes it the world's northernmost capital, a few kilometres farther north than Reykjavík. When home rule was established in 1979, the authorization of place names was transferred to Greenlandic authorities, who preferred Greenlandic names to Danish ones. The name Godthåb mostly went out of use over the next two decades.
The Eoarchean (IPA: /ˌiːoʊ.ɑːrˈkiːən/ EE-oh-ar-KEE-ən; also spelled Eoarchaean) is the first era of the Archean Eon of the geologic record. It spans 431 million years, from the end of the Hadean Eon 4031 Mya to the start of the Paleoarchean Era 3600 Mya. Some estimates place the beginnings of life on Earth in this era, while others place it earlier. Evidence of archaea and cyanobacteria date to 3500 Mya, comparatively shortly after the Eoarchean. At that time, the atmosphere was without oxygen and the pressure values ranged from 10 to 100 bar (around 10 to 100 times the atmospheric pressure today).
