Nunaksaluk Island is an island off the coast of Labrador in the North Atlantic Ocean. The island's indigenous name is translatable to "irrelevant country for habitation". [1] In 1932 HMS Challenger anchored off the island during its surveying of Labrador. [2]
The Strait of Belle Isle is a waterway in eastern Canada, that separates Labrador from the island of Newfoundland, in the province of Newfoundland and Labrador.
Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities, and number of scientific studies.
An iceberg is a piece of freshwater ice more than 15 meters long that has broken off a glacier or an ice shelf and is floating freely in open water. Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits". Much of an iceberg is below the water's surface, which led to the expression "tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard.
Baffin Bay, located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the ice cover and high density of floating ice and icebergs in the open areas. However, a polynya of about 80,000 km2 (31,000 sq mi), known as the North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region.
The Davis Strait is a southern arm of the Arctic Ocean that lies north of the Labrador Sea. It lies between mid-western Greenland and Baffin Island in Nunavut, Canada. To the north is Baffin Bay. The strait was named for the English explorer John Davis (1550–1605), who explored the area while seeking a Northwest Passage. By the 1650s it was used for whale hunting.
The Labrador Sea is an arm of the North Atlantic Ocean between the Labrador Peninsula and Greenland. The sea is flanked by continental shelves to the southwest, northwest, and northeast. It connects to the north with Baffin Bay through the Davis Strait. It is a marginal sea of the Atlantic.
The Torngat Mountains are a mountain range on the Labrador Peninsula at the northern tip of Newfoundland and Labrador and eastern Quebec. They are part of the Arctic Cordillera. The mountains form a peninsula that separates Ungava Bay from the Atlantic Ocean.
HMS Challenger was a survey ship of the United Kingdom's Royal Navy associated with the discovery of Challenger Deep, the deepest point in the oceans. She was laid down in 1930 at Chatham Dockyard and built in a dry dock, before being moved to Portsmouth for completion and commissioning on 15 March 1932.
On 26 December 2004, at 07:58:53 local time (UTC+7), a major earthquake with a magnitude of 9.2–9.3 Mw struck with an epicentre off the west coast of northern Sumatra, Indonesia. The undersea megathrust earthquake, known by the scientific community as the Sumatra–Andaman earthquake, was caused by a rupture along the fault between the Burma Plate and the Indian Plate, and reached a Mercalli intensity up to IX in some areas.
Kaikō was a remotely operated underwater vehicle (ROV) built by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for exploration of the deep sea. Kaikō was the second of only five vessels ever to reach the bottom of the Challenger Deep, as of 2019. Between 1995 and 2003, this 10.6 ton unmanned submersible conducted more than 250 dives, collecting 350 biological species, some of which could prove to be useful in medical and industrial applications. On 29 May 2003, Kaikō was lost at sea off the coast of Shikoku Island during Typhoon Chan-Hom, when a secondary cable connecting it to its launcher at the ocean surface broke.
USS Tanner (AGS-15) was originally built as USS Pamina (AKA-34), an Artemis-class attack cargo ship named after the minor planet 539 Pamina, which in turn was named after a character in Mozart's opera The Magic Flute. However, early in the ship's service it was reclassified AGS-15 and renamed Tanner. She served as a commissioned ship for 24 years and 4 months.
Killiniq Island is a remote island in southeastern Nunavut and northern Newfoundland and Labrador, Canada. Located at the extreme northern tip of Labrador between Ungava Bay and the Labrador Sea, it is notable in that it contains the only land border between Nunavut and Newfoundland and Labrador. Most other islands off the northern coast of Quebec and Labrador belong exclusively to Nunavut. Some cartographic sources do not correctly show the island's geopolitical boundaries; for instance, the Commission de toponymie du Québec seems to show it as belonging to Quebec.
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
USS Pursuit (AM-108) was an Auk-class minesweeper acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.
USS Simon Newcomb (AGSC-14/YMS-263) was a YMS-1-class minesweeper of the YMS-135 subclass acquired by the U.S. Navy during World War II, and whose task was assisting in minesweeping and surveying coastal waters.
Newfoundland is a large island within the Canadian province of Newfoundland and Labrador. It is situated off the eastern coast of the North American mainland and the geographical region of Labrador.
Quest was a low-powered, schooner-rigged steamship that sailed from 1917 until sinking in 1962, best known as the polar exploration vessel of the Shackleton–Rowett Expedition of 1921–1922. It was aboard this vessel that Sir Ernest Shackleton died on 5 January 1922 while in harbour in South Georgia. Prior to and after the Shackleton–Rowett Expedition, Quest operated in commercial service as a seal-hunting vessel or "sealer". Quest was also the primary expedition vessel of the British Arctic Air Route Expedition to the east coast of the island of Greenland in 1930–1931.
The Canadian Arctic Rift System is a major North American geological structure extending from the Labrador Sea in the southeast through Davis Strait, Baffin Bay and the Arctic Archipelago in the northwest. It consists of a series of interconnected rifts that formed during the Paleozoic, Mesozoic and Cenozoic eras. Extensional stresses along the entire length of the rift system have resulted in a variety of tectonic features, including grabens, half-grabens, basins and faults.
Sir Arthur Guy Norris Wyatt KBE CB (1893-1982), often known as Guy Wyatt, was a Royal Navy Officer and Surveyor who was Hydrographer of the Navy in 1945–1950.
