Willem Barentsz (anglicized as William Barents or Barentz) (c. 1550 – 20 June 1597) was a Dutch navigator and explorer, a leader of early expeditions to the far north.

The Barents Sea, Barentsburg and Barents Region were all named after him.

Life

Willem Barentsz was born around the year 1550 on the island Terschelling in the Seventeen Provinces.
A cartographer by trade, Barentsz sailed to Spain and the Mediterranean to complete an atlas of the Mediterranean region, which he co-published with Petrus Plancius.

His career as an explorer was spent searching for the Northeast passage, which he reasoned must exist as clear, open water north of Siberia since the sun shone 24 hours a day, which he believed would have melted any potential ice.

First voyage

On 5 June 1594 Barentsz left the island of Texel aboard the small ship Mercury, as part of a group of three ships sent out in separate directions to try and enter the Kara Sea, with the hopes of finding the Northeast passage above Siberia.

On 9 July, the crew encountered a polar bear for the first time. After shooting it with a musket when it tried to climb aboard the ship, the seamen decided to capture it with the hope of bringing it back to Holland. Once leashed and brought aboard the ship however, the bear rampaged and had to be killed. This occurred in Bear Creek, Williams Island.

Upon discovering the Orange Islands, the crew came across a herd of approximately 200 walruses and tried to kill them with hatchets and pikes. Finding the task more difficult than they imagined, they left with only a few ivory tusks.
Barentsz reached the west coast of Novaya Zemlya, and followed it northward before being forced to turn back in the face of large icebergs. Although they did not reach their ultimate goal, the trip was considered a success.

Second voyage

The following year, Prince Maurice of Orange was filled with "the most exaggerated hopes" on hearing of Barentsz' previous voyage, and named him Chief Pilot and Conductor of a new expedition, which was accompanied by six ships loaded with merchant wares that the Dutch hoped to trade with China.
Setting out on 2 June 1595, the voyage went between the Siberian coast and Vaygach Island. On 30 August, the party came across approximately 20 Samoyed "wilde men" with whom they were able to speak, due to a crewmember speaking their language. 4 September saw a small crew sent to States Island to search for a type of crystal that had been noticed earlier. The party was attacked by a polar bear, and two sailors were killed.

Eventually, the expedition turned back upon discovering that unexpected weather had left the Kara Sea frozen. This expedition was largely considered to be a failure.

Third voyage

In 1596, disappointed by the failure of previous expeditions, the States-General announced they would no longer subsidize similar voyages - but instead offered a high reward for anybody who successfully navigated the Northeast Passage.
The Town Council of Amsterdam purchased and outfitted two small ships, captained by Jan Rijp and Jacob van Heemskerk, to search for the elusive channel under the command of Barents. They set off on 10 May or 15 May, and on 9 June discovered Bear Island.De Veer, Gerrit. "The Three Voyages of William Barentsz to the Arctic Regions" (English trans. 1609).
They discovered Spitsbergen on 17 June, sighting its northwest coast. On 20 June they saw the entrance of a large bay, later called Raudfjorden. On 21 June they anchored between Cloven Cliff and Vogelsang, where they "set up a post with the arms of the Dutch upon it." On 25 June they entered Magdalenefjorden, which they named Tusk Bay, in light of the walrus tusks they found there. The following day, 26 June, they sailed into the northern entrance of Forlandsundet, which they simply called Keerwyck, but were forced to turn back because of a shoal. On 28 June they rounded the northern point of Prins Karls Forland, which they named Vogelhoek, on account of the large number of birds they saw there. They sailed south, passing Isfjorden and Bellsund, which were labelled on Barentsz's chart as Grooten Inwyck and Inwyck.

The ships once again found themselves at Bear Island on 1 July, which led to a disagreement between Barentsz and Van Heemskerk on one side and Rijp on the other. They agreed to part ways, with Barentsz continuing northeast, while Rijp headed due north. Barentsz reached Novaya Zemlya on 17 July. Anxious to avoid becoming entrapped in the surrounding ice, he intended to head for the Vaigatch Strait, but became stuck within the many icebergs and floes.
Stranded, the 16-man crew was forced to spend the winter on the ice, along with their young cabin boy. After a failed attempt to melt the permafrost, the crew used lumber from their ship to build a 7.8x5.5 metre lodge they called Het Behouden Huys (The Kept House).

Dealing with extreme cold, the crew realised that their socks would burn before their feet could even feel the warmth of a fire - and took to sleeping with warmed stones and cannonballs. In addition, they used the merchant fabrics aboard the ship to make additional blankets and clothing.
The ship bore salted beef, butter, cheese, bread, barley, peas, beans, groats, flour, oil, vinegar, mustard, salt, beer, wine, brandy, hardtack, smoked bacon, ham and fish. Much of the beer froze, bursting the casks. By 8 November Gerrit de Veer, the ships carpenter who kept a diary, reported a shortage of beer and bread, with wine being rationed four days later.
In January 1597, De Veer became the first person to witness and record the atmospheric anomaly known as the Novaya Zemlya effect.

Proving successful at hunting, the group caught 26 arctic foxes in primitive traps, as well as killing a number of polar bears.

When June arrived, and the ice had still not loosened its grip on the ship, the scurvy-ridden survivors took two small boats out into the sea on 13 June. Barentsz died at sea on 20 June 1597, while studying charts only seven days after starting out. It is not known whether Barentsz was buried on the northern island of Novaya Zemlya, or at sea. It took seven more weeks for the boats to reach Kola where they were rescued by a Russian merchant vessel, and by that time only 12 crewmen remained. Ultimately, they did not reach Amsterdam until 1 November.Goorich, Frank Boott. "Man Upon the Sea", 1858. Sources differ on whether two men died on the ice floe and three in the boats, or three on the ice floe and two in the boats.De Peyster, John Watts. . March 3, 1857. The young cabin boy had died during the winter months in the shelter.

Excavation and findings

The wooden lodge where Barentsz' crew sheltered was found undisturbed by Norwegian seal hunter Elling Carlsen in 1871. Making a sketch of the lodge's construction, Carlsen recorded finding two copper cooking pots, a barrel, a tool chest, clock, crowbar, flute, clothing, two empty chests, a cooking tripod and a number of pictures. Captain Gunderson landed at the site on 17 August 1875 and collected a grappling iron, two maps and a handwritten translation of Pet and Jackman's voyages. The following year, Charles L.W. Gardiner also visited the site on 29 July where he collected 112 more objects, including the message by Barentsz and Heemskerck describing their settlement to future visitors. All of these objects eventually ended up in the Rijksmuseum Amsterdam, after some had initially been held in The Hague.

The amateur archaeologist Miloradovich 's 1933 finds are held in the Arctic and Antarctic Museum in St. Petersburg Dmitriy Kravchenko visited the site in 1977, 1979 and 1980 - and sent divers into the sea hoping to find the wreck of the large ship. He returned with a number of objects, which went to the Russian Arkangel's Regional Museum. Another small collection exists at the Polar Museum in Tromsø.
In 1992, an expedition of three scientists, a journalist and two photographers commissioned by the Arctic Centre at the University of Groningen, coupled with two scientists, a cook and a doctor sent by the Arctic and Antarctic Research Institute in St. Petersburg, returned to the site, and erected a commemorative marker at the site of the cabin.

The location of Barentsz' wintering on the ice floes has become a tourist destination for icebreaker cruiseships operating from Murmansk.

Legacy

Two of Barentsz' crewmembers later published their journals, Jan Huyghen van Linschoten who had accompanied him on the first two voyages, and Gerrit de Veer who had acted as the ship's carpenter on the last two voyages.

In 1853, the former Murmean Sea was renamed Barents Sea in his honour.

In the late 19^th-century, the Maritime Institute Willem Barents was opened on Terschelling.

In 1878, the Netherlands christened the Willem Barentsz Arctic exploration ship.

In 1931, Nijgh & Van Ditmar published a play written by Albert Helman about Barentsz' third voyage, although it was never performed.

In 1946, the Whaling ship Pan Gothia was re-christened the Willem Barentsz. In 1953, the second Willem Barentsz whaling ship was produced.

A protein in the molecular structure of the fruit fly was named Barentsz, in honour of the explorer.
