The Tasman Sea is the large body of water between Australia and New Zealand, approximately 2,000 kilometres (1,200 mi) across. It extends 2,800 km (approx.) from north to south. It is a south-western segment of the South Pacific Ocean. The sea was named after the Dutch explorer Abel Janszoon Tasman, the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration.

The Tasman Sea is commonly referred to in both Australia and New Zealand as The Ditch; for example, crossing the ditch means going to Australia from New Zealand or vice versa. In Māori, the Tasman Sea is called Te Tai-o-Rehua.^[1]

Geography[link]

Extent[link]

The International Hydrographic Organization defines the limits of the Tasman Sea as follows:^[2]

On the West. A line from Gabo Island (near Cape Howe, 37°30'S) to the Northeast point of East Sister Island (148°E) thence along the 148th meridian to Flinders Island; beyond this Island a line running to the Eastward of the Vansittart Shoals to [Cape] Barren Island, and from Cape Barren (the Easternmost point of [Cape] Barren Island) to Eddystone Point (41°S) in Tasmania, thence along the East coast to South East Cape, the Southern point of Tasmania.

On the North. The parallel of 30°S from the Australian coast Eastward as far as a line joining the East extremities of Elizabeth Reef and South East Rock (31°47′S 159°18′E / 31.783°S 159.3°E / -31.783; 159.3) then to the Southward along this line to the South East Rock.

On the Northeast. From the South East Rock to the North point of Three Kings Islands (34°10′S 172°10′E / 34.167°S 172.167°E / -34.167; 172.167) thence to North Cape in New Zealand.

On the East.

• In Cook Strait. A line joining the South extreme of the foul ground off Cape Palliser (Ngawi) and the Lighthouse on Cape Campbell (Te Karaka).
• In Foveaux Strait (46°45'S). A line joining the Light on Waipapapa Point [sic] (168°33'E) with East Head (47'02'S) of Stewart Island (Rakiura).

On the Southeast. A line running from South West Cape, Stewart Island, through The Snares (48°S, 166°30'E) to North West Cape, Auckland Island (50°30′S 166°10′E / 50.5°S 166.167°E / -50.5; 166.167), through this island to its Southern point.

On the South. A line joining the Southern point of Auckland Island (50°55′S 166°0′E / 50.917°S 166°E / -50.917; 166) to South East Cape, the Southern point of Tasmania.

Ridge[link]

The Tasman Sea's mid-ocean ridge developed between 85 and 55 million years ago as Australia and Zealandia broke apart during the breakup of supercontinent Gondwana. It lies roughly midway between the continental margins of Australia and Zealandia. Much of Zealandia is submerged, so the ridge runs much closer to the Australian coast than New Zealand's.

Islands[link]

The Tasman Sea features a number of mid-sea island groups, quite apart from coastal islands located near the Australian and New Zealand mainlands:

• Lord Howe Island (part of New South Wales)
• Ball's Pyramid (part of New South Wales)
• Norfolk Island, in the extreme north of the Tasman Sea, on the border with the Coral Sea (External Territory)
• Middleton Reef (part of Coral Sea Islands Territory)
• Elizabeth Reef (part of Coral Sea Islands Territory)

Adjoining bodies of water[link]

• North: Coral Sea
• Northeast and East: Pacific Ocean
• South and Southeast: Southern Ocean
• West: Bass Strait

History[link]

Moncrieff and Hood were the first to attempt to a Trans-Tasman crossing by plane in 1928. The first successful flight over the sea was accomplished by Charles Kingsford Smith later that year. The first person to row solo across the sea was Colin Quincey in 1977. The next successful solo crossing was completed by his son, Shaun Quincey in 2010.^[3]

Abel Janszoon Tasman (Dutch: [ˈaːbəl ˈjɑnsoʊn ˈtɑsmɐn]; 1603–1659) was a Dutch seafarer, explorer and merchant, best known for his voyages of 1642 and 1644 in the service of the VOC (United East India Company). His was the first known European expedition to reach the islands of Van Diemen's Land (now Tasmania) and New Zealand, and to sight the Fiji islands. His navigator François Visscher, and his merchant Isaack Gilsemans, mapped substantial portions of Australia, New Zealand and some Pacific Islands.

First Pacific voyage[link]

Abel Tasman was born in 1603 in Lutjegast in what is now the province of Groningen, the Netherlands. In 1633, Tasman went to Batavia in service of the VOC; four years later he was back in Amsterdam. Tasman signed on for another ten years and took his wife along to Batavia. In 1639 Tasman was sent as second in command of an exploring expedition in the north Pacific under Matthijs Quast. His fleet included the ships Engel and Gracht and reached Fort Zeelandia (Dutch Formosa) and Deshima.

In August 1642, the Council of the Indies, consisting of Antonie van Diemen, Cornelis van der Lijn, Joan Maetsuycker, Justus Schouten, Salomon Sweers, Cornelis Witsen, and Pieter Boreel in Batavia despatched Abel Tasman and Franchoijs Visscher on a voyage of which one of the objects was to obtain knowledge of "all the totally unknown provinces of Beach".^[3]

Beach and Terra Australis[link]

Beach appeared on maps of the time, notably that of Abraham Ortelius of 1570 and that of Jan Huygen van Linschoten of 1596, as the northernmost part of the southern continent, the Terra Australis, along with Locach. According to Marco Polo, Locach was a kingdom where gold was “so plentiful that no none who did not see it could believe it”. Beach was in fact a mistranscription of Locach. Locach was Marco Polo’s name for the southern Thai kingdom of Lavo, or Lop Buri, the “city of Lavo”, (ลพบร, after Lavo, the son of Rama in Hindu mythology).^[4] In Chinese (Cantonese), Lavo was pronounced “Lo-huk” (羅斛), from which Marco Polo took his rendition of the name.^[5] In the German cursive script, “Locach” and “Beach” look similar, and in the 1532 edition of Marco Polo’s Travels his Locach was changed to Boëach, later shortened to Beach.^[6] They seem to have drawn on the map of the world published in Florence in 1489 by Henricus Martellus, in which provincia boëach appears as the southern neighbour of provincia ciamba. Book III of Marco Polo’s Il Milione described his journey by sea from China to India by way of Champa (= Southern Vietnam), Java (which he called Java Major), Locach and Sumatra (called Java Minor). After a chapter describing the kingdom of Champa there follows a chapter describing Java (which he did not visit himself).^[7] The narrative then resumes, describing the route southward from Champa toward Sumatra, but by a slip of the pen the name “Java” was substituted for “Champa” as the point of departure, locating Sumatra 1,300 miles to the south of Java instead of Champa. Locach, located between Champa and Sumatra, was likewise misplaced far to the south of Java, by some geographers on or near an extension of the Terra Australis.^[8] As explained by Sir Henry Yule, the editor of an English edition of Marco Polo’s Travels: “Some geographers of the 16th century, following the old editions which carried the travellers south-east of Java to the land of “Boeach” (or Locac), introduced in their maps a continent in that situation”.^[9] Gerard Mercator did just that on his 1541 globe, placing Beach provincia aurifera (“Beach the gold-bearing province”) in the northernmost part of the Terra Australis in accordance with the faulty text of Marco Polo’s Travels. It remained in this location on his world map of 1569, with the amplified description, quoting Marco Polo, Beach provincia aurifera quam pauci ex alienis regionibus adeunt propter gentis inhumanitatem (“Beach the gold-bearing province, wither few go from other countries because of the inhumanity of its people”) with Lucach regnum shown somewhat to its south west.^[10] Following Mercator, Abraham Ortelius also showed BEACH and LVCACH in these locations on his world map of 1571. Likewise, Linschoten’s very popular 1596 map of the East Indies showed BEACH projecting from the map’s southern edge, leading (or misleading) Visscher and Tasman in their voyage of 1642 to seek Beach with its plentiful gold in a location to the south of the Solomon Islands somewhere between Staten Land near Cape Horn and the Cape of Good Hope.^[11] Confirmation that land existed where the maps showed Beach to be had come from Dirk Hartog’s landing in October 1616 on its west coast, which he called Eendrachtsland after the name of his ship. Abel Tasman endured a very rough journey from Tasmania to New Zealand. In one of his diary entries Tasman credits his compass, claiming it was the only thing that kept him alive.

Mauritius[link]

In accordance with Visscher's directions, Tasman sailed first to Mauritius and arrived on 5 September 1642. The reason for this was the crew could be fed well on the island; there was plenty of fresh water and timber to repair the ships. Tasman got the assistance of the governor Adriaan van der Stel. Because of the prevailing winds Mauritius was chosen as a turning point. After a four week stay on the island both ships left on 8 October. After one month it started to snow and hail; Tasman changed course more north. Part of the western shore of the continent was already known to the Dutch, but no one had gone as far as Pieter Nuyts.

Tasmania[link]

On 24 November 1642 Abel Tasman sighted the west coast of Tasmania, north of Macquarie Harbour.^[12] He named his discovery Van Diemen's Land after Anthony van Diemen, Governor-General of the Dutch East Indies. Proceeding south he skirted the southern end of Tasmania and turned north-east, Tasman then tried to work his two ships into Adventure Bay on the east coast of South Bruny Island where he was blown out to sea by a storm, this area he named Storm Bay. Two days later Tasman anchored to the North of Cape Frederick Hendrick just North of the Forestier Peninsula. Tasman then landed in Blackman Bay – in the larger Marion Bay. The next day, an attempt was made to land in North Bay; however, because the sea was too rough the carpenter swam through the surf and planted the Dutch flag in North Bay. Tasman then claimed formal possession of the land on 3 December 1642.

New Zealand[link]

After some exploration, Tasman had intended to proceed in a northerly direction but as the wind was unfavourable he steered east. On 13 December they sighted land on the north-west coast of the South Island, New Zealand, becoming the first Europeans to do so.^[13] Tasman named it Staten Landt on the assumption that it was connected to an island (Staten Island, Argentina) at the south of the tip of South America. Proceeding north and then east, he stopped to gather water, but one of his boats was attacked by Māori in waka (canoes) and four of his men and several Māori^[14] were killed. Archeological research has shown the Dutch had tried to land at a major agricultural area, which the Māori may have been trying to protect.^[15] Tasman named the bay Murderers' Bay (now known as Golden Bay) and sailed north, but mistook Cook Strait for a bight (naming it Zeehaen's Bight). Two names he gave to New Zealand landmarks still endure, Cape Maria van Diemen and Three Kings Islands, but Cabo Pieter Boreels is now known as Cape Egmont.

The return voyage[link]

On route back to Batavia, Tasman came across the Tongan archipelago on 20 January 1643. While passing the Fiji Islands Tasman's ships came close to being wrecked on the dangerous reefs of the north-eastern part of the Fiji group. He charted the eastern tip of Vanua Levu and Cikobia before making his way back into the open sea. He eventually turned north-west to New Guinea, and arrived at Batavia on 15 June 1643.

Second Pacific voyage[link]

With three ships on his second voyage (Limmen, Zeemeeuw and the tender Braek) in 1644, he followed the south coast of New Guinea eastwards. He missed the Torres Strait between New Guinea and Australia, and continued his voyage along the Australian coast. He mapped the north coast of Australia making observations on the land, called New Holland, and its people.

From the point of view of the Dutch East India Company Tasman's explorations were a disappointment: he had neither found a promising area for trade nor a useful new shipping route. Although received modestly, the company was upset to a degree that Tasman didn't fully explore the lands he found, and decided that a more "persistent explorer" should be chosen for any future expeditions.^[16] For over a century, until the era of James Cook, Tasmania and New Zealand were not visited by Europeans – mainland Australia was visited, but usually only by accident.

Later life[link]

On 2 November 1644 Abel Tasman was appointed a member of the Council of Justice at Batavia. He went to Sumatra in 1646, and in August 1647 to Siam (now Thailand) with letters from the company to the King. In May 1648 he was in charge of an expedition sent to Manila to try to intercept and loot the Spanish silver ships coming from America, but he had no success and returned to Batavia in January 1649. In November 1649 he was charged and found guilty of having in the previous year hanged one of his men without trial, was suspended from his office of commander, fined, and made to pay compensation to the relatives of the sailor. On 5 January 1651 he was formally reinstated in his rank and spent his remaining years at Batavia. He was in good circumstances, being one of the larger landowners in the town. He died at Batavia in October 1659 and was survived by his second wife and a daughter by his first wife. The poor in Lutjegast received the small amount of only 25 guilders.^[17]

Tasman's legacy[link]

As with many explorers, Tasman's name has been honoured in many ways. These include:

• the Australian island Tasmania, renamed after him, formerly Van Diemen's land. It includes features such as:
  • the Tasman Peninsula
  • the Tasman Bridge
  • the Tasman Highway
  • the former passenger/vehicle ferry Abel Tasman
  • and, indirectly, two marsupial species are named after Tasman:
    • the Tasmanian Devil
    • the Tasmanian Tiger
• a plant genus
  • Tasmannia
• the Tasman Sea
• in New Zealand:
  • the Tasman Glacier
  • Tasman Lake
  • the Tasman River
  • Mount Tasman
  • the Abel Tasman National Park
  • Tasman Bay
  • the Tasman District
  • Abel Tasman Drive, in Takaka.
  • the Abel Tasman Memorial in Takaka.
• The Able Tasmans – an indie band from Auckland, New Zealand.

In 1985 he was honoured on a postage stamp depicting his portrait issued by Australia Post.^[18]
