Context paragraphs:
William Gardner (English coin designer): William Maving Gardner (25 May 1914 in Newcastle – 28 December 2000) was an English coin designer, engraver, calligrapher and writer who worked regularly for the Royal Mint over a 30-year period.  He is notable for designing coins such as the British 20 Pence Coin and some of the coins of Cyprus, New Zealand, Jordan, Guyana, Dominican Republic, Sri Lanka and the Falkland Islands.

Livar Nysted: Livar Nysted (born 1970) who grew up in the small village Hvannasund in the Faroe Islands is an ocean rower and an artist, a painter.  He has achieved five world records in ocean rowing.  In 2010 he - together with three other rowers successfully crossed the North Atlantic Ocean in a rowing boat, breaking a 114-year-old record.  In January 2013 he went on another journey, this time the plan was to cross the South Atlantic Ocean with a boat called Avalon, the crew was eight men, they started on 18 January from Puerto de Mogán, Grand Canaria, their plan was to row to Port Saint Charles, Barbados.  They made it all the way to Barbados on 22 February 2013 after rowing for 32 days, 12 hours and 41 minutes.  Later the same year Nysted went on another expedition together with two other men.  Their journey started in Australia on 9 June 2013.  They crossed the Indian Ocean by rowing.  They arrived at Mauritius on 5 August 2013 after rowing for 57 days, 15 hours and 49 minutes, which was a new world record.  Livar sat three world records after completing this journey: he and the two others were the first crew of three to cross the Indian Ocean, they were also the fastest rowing crew to row this distance and Livar sat a new world record for having crossed two oceans in a rowing boat within the same year.

Mid-Atlantic Ridge: The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.  In the North Atlantic it separates the Eurasian and North American Plates, and in the South Atlantic it separates the African and South American Plates.  The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic.  Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level.  The section of the ridge that includes the island of Iceland is also known as the Reykjanes Ridge.  The ridge has an average spreading rate of about 2.5 cm per year.

South Atlantic tropical cyclone: South Atlantic tropical cyclones are unusual weather events that occur in the Southern Hemisphere.  Strong wind shear, which disrupts the formation of cyclones, as well as a lack of weather disturbances favorable for development in the South Atlantic Ocean make any strong tropical system extremely rare, and Catarina in 2004 was the only recorded South Atlantic hurricane in history.  Those storms have only developed during the months from November through to April in this basin.  Since 2011, the Brazilian Navy Hydrographic Center has started to assign names to tropical and subtropical systems in western side of this basin near Brazil, when they have sustained wind speeds of at least 65 km/h (40 mph), the generally accepted minimum sustained wind velocity for a disturbance to be designated as a tropical storm in the North Atlantic basin.  Below is a list of notable South Atlantic tropical and subtropical cyclones.

Parting of the Waters: Parting of the Waters is an unusual hydrologic site at Two Ocean Pass on the Great Divide, within the Teton Wilderness area of Wyoming's Bridger-Teton National Forest.  Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean.  At Parting of the Waters, at , North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters more-or-less equally between its two distributaries, Pacific Creek and Atlantic Creek.  From this split, Two Ocean Creek waters flow either 3488 mi to the Atlantic Ocean via Atlantic Creek and the Yellowstone, Missouri and Mississippi Rivers, or 1353 mi to the Pacific Ocean via Pacific Creek and the Snake and Columbia Rivers.  In the marshy area of Two Ocean Pass adjacent to Parting of the Waters, water actually covers the Continental Divide such that a fish could swim from the Pacific Ocean to the Atlantic Ocean drainages.  In fact, it is thought that this was the pass that provided the route for Yellowstone cutthroat trout to migrate from the Snake River (Pacific) to Yellowstone River (Atlantic) drainages.

Tristan da Cunha: Tristan da Cunha ( ), colloquially Tristan, is the name of both a remote group of volcanic islands in the south Atlantic Ocean and the main island of that group.  It is the most remote inhabited archipelago in the world, lying 2000 km from the nearest inhabited land, Saint Helena, and 2400 km from the nearest continental land, South Africa.  It is 3360 km from South America.  The territory consists of the main island, named Tristan da Cunha, which has a north–south length of 11.27 km and an area of 98 km2 , along with the smaller, uninhabited Nightingale Islands and the wildlife reserves of Inaccessible and Gough islands.  As of January 2017, the main island has 262 permanent inhabitants.  The other islands are uninhabited, except for the personnel of a weather station on Gough Island.

South Atlantic Convergence Zone: The South Atlantic convergence zone, or SACZ, is an elongated axis of clouds, precipitation, and convergent winds oriented in a northwest-southeast manner across southeast Brazil into the southwest Atlantic Ocean.  By definition, the feature is a monsoon trough.  It is strongest in the warm season.  Thunderstorm activity along the feature magnifies over three or more days when the Madden–Julian oscillation passes into the region, due to the enhanced upper divergence.  Low level winds over Rondônia are tied to the strength of this zone, where westerly wind anomalies correlate to active phases of the South American monsoon, while easterly wind anomalies indicate breaks of activity along the SACZ.  The feature is also strongest with negative anomalies in the sea surface temperature pattern lie over the southern Atlantic Ocean, while opposite conditions prevail across the northern Atlantic Ocean.

SACS (cable system): The South Atlantic Cable System or SACS (Portuguese: "Sistema de Cabo do Atlântico Sul" ), also known as the Angola-Brazil Cable, is a planned submarine communications cable in the South Atlantic Ocean linking Luanda, Angola with Fortaleza, Brazil with a leg connecting the Brazilian archipelago of Fernando de Noronha as well.  It is designed to provide low latency routing between Africa and Asia in the east and the Americas in the west.  Data traffic between Angola and Brazil will no longer have to pass through Europe and the US, as currently occurs.

Falkland Islands: The Falkland Islands ( ; Spanish: "Islas Malvinas" , ] ) are an archipelago in the South Atlantic Ocean on the Patagonian Shelf.  The principal islands are about 300 mi east of South America's southern Patagonian coast, at a latitude of about 52°S.  The archipelago, with an area of 4700 sqmi , comprises East Falkland, West Falkland and 776 smaller islands.  As a British overseas territory, the Falklands have internal self-governance, and the United Kingdom takes responsibility for their defence and foreign affairs.  The islands' capital is Stanley on East Falkland.

List of South America hurricanes: A South American hurricane is a tropical cyclone that affects the continent of South America or its countries.  The continent is rarely affected by tropical cyclones, though most storms to hit the area are formed in the North Atlantic Ocean. </onlyinclude> Typically, strong upper level winds and its proximity to the equator prevents North Atlantic impacts.  No tropical cyclone has ever affected the Pacific side of South America.  Although conditions are typically too hostile for many storms to hit the area from the South Atlantic Ocean, there have been a few tropical cyclones to affect land.  Based on climatology, northern Venezuela and Colombia have a 1 to 5% chance of a hurricane strike in any given year, while all locations south of 10° N have less than a 1% chance of a direct hit.  A total of 43 tropical cyclones have affected the continent since 1588.
