Answer 1

Answer:

hey mate

here is your answer

Explanation:

The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Nova Scotia. It is a continuation of the West Greenland Current and the Baffin Island Current.

Answer 2

Explanation:

The Labrador Current is a surface oceanic current in the North Atlantic Ocean that originates at the Davis Strait, where it begins as a continuation of the West Greenland Current and the Baffin Island Current. From there it flows southwards along the western side of the Labrador Sea. The current passes along the coasts of Labrador, Newfoundland, and the east coast of Nova Scotia in Canada. The Labrador Current is a cold current with low salinity, and reaches a maximum depth of around 2,000 feet. It carries a volume of water ranging between 125,000,000 and 190,000,000 cubic feet, and transports numerous icebergs southward.

The Labrador Current has always acted as a determinant of the climatic patterns of Canada’s eastern coastal areas. The waters of the current once thrived with commercially important fish species like Atlantic cod, which sustained large scale commercial fishing in the region. The Labrador Current has also been held responsible for a number of major marine disasters of the past. The icebergs and sea-ice sheets carried by the current have often led to numerous shipwrecks, including the sinking of the ill-fated R.M.S. Titanic in the Spring of 1912, in the frigid waters of the Labrador Current off the coast of Newfoundland. Fog created in the region, most notably where the cold waters of the Labrador Current meet the warm waters of the Gulf Stream, has also blinded and sealed the fate of many navigation vessels in the past.

Modern Significance

The Labrador Current plays a major role in influencing the climate of the Canadian provinces lying along its path. The relatively lower salinity of the current compared to the waters of the central parts of the Atlantic Ocean makes the water easily susceptible to freezing. The cold waters of the Labrador Current thus have a moderating effect on the climate of the coastal lands in its path, making the summers there cooler, and winters more severely cold. The numerous icebergs in the path of the Labrador Current often act as a barrier to the safe passage of ships. However, the purity of these same icebergs have made them a commercially attractive source of pure water, and also attracts a large number of tourists into the region for iceberg viewing.

Habitat and Biodiversity

The water temperatures of the Labrador Current are typically maintained below 32° Fahrenheit (0° Celsius), and its waters have salinities ranging between 30 and 34 parts per 1,000. These fast-flowing cold waters have traditionally supported a diversity of aquatic life, including such fish species as cod, American plaice, capelin, and Greenland halibut, as well as invertebrates like Snow crabs and Northern shrimps. Harp seals and whales are the large predatory aquatic mammals of the Labrador Current ecosystems. However, overfishing over the last several decades has greatly reduced the fish species of the region, and conversely promoted a population explosion among the invertebrates. Fisheries in the region thus generate profits from the large scale shrimp and Snow crab catches from the waters of the Labrador Current at levels never seen before.
