Map showing the Grand Banks

Historic map including the Grand Banks.
The 'Grand Banks' are a group of underwater
plateaus southeast of
Newfoundland on the
North American
continental shelf. These areas are relatively shallow, ranging from 25 to 100 metres in depth. The cold
Labrador Current mixes with the warm waters of the
Gulf Stream here.
The mixing of these waters and the shape of the ocean bottom lifts nutrients to the surface. These conditions created one of the richest
fishing grounds in the world.
Fish species include
Atlantic cod,
haddock and
capelin.
Shellfish include
scallop and
lobster. The area also supports large colonies of
sea birds such as
Northern Gannets,
shearwaters and
sea ducks and various sea
mammals such as
seals,
dolphins and
whales.
In addition to the effects on nutrients, the mixing of the cold and warm currents often causes
fog in the area.
Several navigators, including
Basque fishermen, are known to have fished these waters in the
15th century. In the 15th century some texts refer to a land called ''
Bacalao'', the land of the codfish, which is possibly Newfoundland. However, it was not until
John Cabot reached the New World in
1497 that the existence of these fishing grounds became generally known in
Europe. Ships from
France,
Spain,
Portugal and
England came to fish these waters. These fish stocks were also important for the early economies of eastern
Canada and
New England.
On
November 18,
1929, a major
earthquake (known as the
1929 Grand Banks earthquake) on the southwestern part of the Grand Banks bordering the Laurentian Channel caused an underwater landslide which resulted in extensive damage to
transatlantic cables and generated a rare Atlantic
tsunami that struck the south coast of
Newfoundland and eastern
Cape Breton Island claiming 27 lives in the
Burin Peninsula.
Technological advances in fishing such as large factory ships and
sonar, as well as geopolitical disputes over
territorial sea and
exclusive economic zone (EEZ) boundaries, have led to
overfishing and a serious decline in the fish stocks of the Grand Banks from around
1990. Fishery-based economy of Newfoundland is in a severe crisis from 1990s. Canada's EEZ currently occupies the majority of the Grand Banks except for the lucrative "nose" (eastern extremity, near the
Flemish Cap) and "tail" (southern extremity) of the fishing bank. However, the
Treaty of Paris (1783) gives the
United States shared rights to fish these waters, despite the EEZ.
Canada is currently performing the hydrographic and geological surveys necessary for claiming the entire continental shelf off eastern Canada, under the auspices of the latest
United Nations Convention on the Law of the Sea. Once this aspect of UNCLOS is ratified, Canada will presumably control these remaining parts of Grand Banks which are outside of its EEZ jurisdiction.
Petroleum reserves have also been discovered and a number of oil fields are under development in this region, most notably the
Hibernia,
Terra Nova, and
White Rose projects; the harsh environment on the Grand Banks also led to the ''
Ocean Ranger'' disaster.
Semi-fictional depictions of fishermen working on the Grand Banks can be found in Sebastian Junger's novel ''
The Perfect Storm'' (1997) and in
Rudyard Kipling's novel ''
Captains Courageous'' (1897).
