Geography
[edit]
Lofoten and Vesterålen
Lofoten is located at the 68th and 69th parallels north of the Arctic Circle in North Norway. Lofoten encompasses the municipalities of Vågan, Vestvågøy, Flakstad, Moskenes, Værøy, and Røst. The principal islands, running from north to south, are:
Southern tip of Hinnøya.
Southern 60% (approx.) of Austvågøya (526.7 square kilometres (203.4 square miles) in total 68°20′N 14°40′E / 68.333°N 14.667°E / 68.333; 14.667)
Gimsøya (46.4 square kilometres (17.9 square miles) 68°18′N 14°11′E / 68.300°N 14.183°E / 68.300; 14.183)
Vestvågøya (411.1 square kilometres (158.7 square miles) 68°10′N 13°45′E / 68.167°N 13.750°E / 68.167; 13.750)
Flakstadøya (109.8 square kilometres (42.4 square miles) 68°5′N 13°20′E / 68.083°N 13.333°E / 68.083; 13.333)
Moskenesøya (185.9 square kilometres (71.8 square miles) 67°55′N 13°0′E / 67.917°N 13.000°E / 67.917; 13.000)

Further to the south are the small and isolated islands of Værøy Municipality (67°40′N 12°40′E / 67.667°N 12.667°E / 67.667; 12.667) and Røst Municipality (67°37′N 12°7′E / 67.617°N 12.117°E / 67.617; 12.117). The total land area amounts to 1,227 square kilometres (474 square miles), and the population totals 24,500. Many will argue that Hinnøya, the northern part of Austvågøya and several hundred smaller islands, skerries, and rocks to the east of Austvågøya are also part of the Lofoten district. Historically, the territorial definition of Lofoten has changed significantly. Between the mainland and the Lofoten archipelago lies the vast, open Vestfjorden, and to the north is the Vesterålen district. The principal towns in Lofoten are Leknes in Vestvågøy Municipality and Svolvær in Vågan Municipality. The main islands are joined to each other and the mainland by road bridges.
The Lofoten Islands are characterised by their mountains and peaks, sheltered inlets, stretches of seashore and large virgin areas. The highest mountain in Lofoten is Higravstinden (1,161 metres (3,809 feet)) in Austvågøy; the Møysalen National Park just northeast of Lofoten has mountains reaching 1,262 metres (4,140 feet). The famous Moskstraumen (Malstrøm) system of tidal eddies is located in western Lofoten, and is indeed the root of the term maelstrom.
Geology[edit]

Geological map of Lofoten and Vesterålen
Lofoten is a horst ridge of bedrock. The rocks of Lofoten belong to the wider Western Gneiss Region of Norway. Some of the high relief and irregular surfaces of Lofoten has been attributed to etching that took place during the Mesozoic Era. Evidence of this would be the kaolinite found at some locations. To the northwest the Lofoten archipelago is bounded by the NE–SW-trending West Lofoten Border Fault. This is a normal fault whose fault scarp has been eroded, forming a strandflat.
In Vestvågøya, mountains have steep slopes towards the open sea in the northwest and southeast, while slopes pointing towards the interior of the island are more gradual. This is the result of erosion acting on a landscape that has been uplifted along NE–SW-trending faults in the margins of Lofoten while the interior axis has remained more stable. In tectonic terms mountains are half-grabens and faults are of the dip-slip type.
The sea around Lofoten is known to host significant oil reserves: 1.3 bn barrels. Oil extraction in the Lofoten area is prohibited.
Oceanography[edit]
The Lofoten archipelago lies along the eastern margin of the Lofoten Basin Vortex (also referred to as the Lofoten Basin Eddy), a deep depression in the Norwegian Sea that reaches the depths of over 3,000 M, which acts as a major heat reservoir in the Nordic Seas. Most of this is due to the inflow of the warm, saline Atlantic Water, which plays an important role in regional water mass transformation.
This regional circulation is dominated by two branches of the Norwegian Atlantic Current (NwAC)
The Norwegian Atlantic Slope Current, which flows northwards along the continental shelf break and the steep Lofoten Escarpment.
The Norwegian Atlantic Front Current, which follows a more offshore path along the Mohn, Knipovich Ridge. This forms a sharp hydrographic front between the warmer Atlantic waters in the east and the colder, fresher waters of Arctic origin in the west.
The interactions between the Norwegian Atlantic Current and the fresher Norwegian Coastal Current are particularly active in the Lofoten Basin, where the high eddy activity enhances the mixing and tracer exchanges between the two currents. Now the Lofoten Vortex itself is a semi-permanent feature that is distinguishable by its unusual location, longevity, and deep vertical structure, especially with the Atlantic Water penetrating down to approximately 1,000 m in depth within the eddy core. Observations seen from Seagliders over three years (2012-2015) have revealed a detailed evolution, showing that the vortex maintains a weakly stratified core and plays a significant role in the dissipation of kinetic energy in the basin.
Wildlife[edit]
The sea is rich with life, and the world's largest deep water coral reef, called the Røst Reef, is located west of Røst. Approximately 70% of all fish caught in the Norwegian and Barents seas use its islands' waters as a breeding ground. Otters are common, and there are elk on the largest islands. There are some woodlands with downy birch and rowan. There are no native conifer forests in Lofoten, but some small areas with private spruce plantations. Hedlundia hybrida and Malus sylvestris occurs in Lofoten, but not further north.
Birds[edit]
Some 27,000 hectares (100 mi2) of marine waters along the north-western coasts and fjords of the Lofoten Islands have been designated an Important Bird Area (IBA) by BirdLife International (BLI) because it supports overwintering populations of common eiders and yellow-billed loons. The IBA contains or overlaps with the Seløya, Morfjorden, Laukvikøyene, Eggum and Borgværet nature reserves, as well as the Laukvikøyene Ramsar site. Lofoten has a high density of sea eagles and cormorants, and millions of other sea birds, among them the colourful puffin. It has the largest seabird colony in mainland Europe. The birds once mistaken for the extinct great auk turned out to be some of the nine king penguins released around Norway's Lofoten Islands in August 1936, there until at least 1944.
Climate[edit]
Lofoten features a mostly subpolar oceanic climate (Cfc) under the Köppen climate classification, although some areas, such as Skrova, feature a temperate oceanic climate (Cfb). Winter temperatures in Lofoten are extremely mild considering its location north of the Arctic Circle – possibly the largest positive temperature anomaly in the world relative to latitude. The mild winters are a result of the temperate waters of the Norwegian Sea, which is warmed by the North Atlantic Current and the Norwegian Current. The mild air (Lows) from the Atlantic, having a free path northwards even in winter, is also very significant.
Strong winds can occur in late autumn and winter. Snow and sleet are not uncommon in winter. The mountains can have substantial snowfall, and avalanches may occur on steep slopes.
In Svolvær, the sun is above the horizon continuously ("midnight sun") from 25 May to 17 July, and in winter the sun does not rise from 4 December to 7 January. In Leknes, the sun is above the horizon from 26 May to 17 July, and in winter, the sun does not rise from 9 December to 4 January.
Sea temperatures have been recorded since 1935. At 1 metre (3 feet 3 inches) depth in the sea near Skrova, water temperatures vary from a low of 3 °C (37 °F) in March to 14 °C (57 °F) in August, some years peaking above 17 °C (63 °F). November is around 7–8 °C (45–46 °F). At a depth of 200 metres (660 feet), the temperature is near 8 °C (46 °F) all year.
Skrova lighthouse on an island near Svolvær has the longest recording of air temperature in Lofoten. The highest temperature recorded is 30.4 °C (86.7 °F) in June 1972. The lowest temperature recorded is −15.1 °C (4.8 °F) in February 1966. The last overnight freeze in June occurred in 1962, and the last in September occurred in 1986. Skrova and nearby Svolvær are among the places in North Norway that can record what Norwegians call "tropical nights," when the overnight low does not drop below 20 °C (68 °F). The warmest night recorded in Lofoten was July 1, 1972 at Skrova with low 23.8 °C (74.8 °F), and the earliest in summer was June 10, 2011 with low 21.5 °C (70.7 °F). The wettest month recorded is December 1936 with 227 mm, and the driest is January 2014 with 0.9 mm.

Even if the islands are not that large, there are climatic differences. Værøy and Røst, which are furthest west, have the warmest winters, but summer highs are cooler. Vestvågøy, with the town of Leknes, has lowland in the island's interior, with mountains nearby; winters here are slightly colder and much wetter than at Skrova, while summers are drier and comparable.
