HMSInvestigator was a merchant ship purchased in 1848 to search for SirJohn Franklin's ill-fatedNorthwest Passage expedition. She made two voyages to the Arctic and had to be abandoned in 1853, after becoming trapped in the pack ice.
Her wreckage was found in July 2010, offBanks Island in theBeaufort Sea. She was the fourth ship of theRoyal Navy to bear the name.
Built atScotts Shipbuilding and Engineering Company ofGreenock on theFirth of Clyde, and running 422 tonnes,Investigator was purchased by the Admiralty in February 1848 and was fitted forArctic exploration by R. & H. Green atBlackwall Yard on theRiver Thames.[2]
She was strengthened for Arctic service by William M. Rice, master shipwright ofWoolwich Dockyard. She was extensively strengthened with timber—teak,English oak, Canadianelm—and5⁄16 in (8 mm) steel plating. Ten pairs ofwrought iron diagonal riders were set in the hold, with ten pairs of diagonal plates on the sides of the vessel between decks.
To cope with snow and ice loads, the upper decks were doubled with 3 in (76 mm)fir planking. Preston's Patent Ventilating Illuminators were installed to improve light and ventilation.Charles Sylvester's warming apparatus, a modern stove system capable of warming the entire ship, was also employed with good results.[3] The same or similar device had been used byWilliam Edward Parry in 1821, to prevent condensation and aerate the lowest deck.

In 1848, she accompaniedHMS Enterprise onJames Clark Ross's expedition to findFranklin's lost expedition. Also aboardInvestigator on this expedition was the naturalistEdward Adams. On a separate expedition she was commanded byRobert McClure,[4] but the ship became trapped in the pack ice atMercy Bay adjoiningBanks Island. The decision was eventually taken to abandon her on 3 June 1853, after she had been stuck for nearly three years.[2]
The following year, she was inspected by crews ofHMS Resolute, still frozen in, and reported to be in generally fair condition despite having taken on some water during the summer thaw.
Unlike the loss ofErebus andTerror, the events surroundingInvestigator's abandonment are not a mystery. McClure provided an official account of the journey, and the ship's surgeon,Alexander Armstrong, published an unofficial account in 1857.[5] However, the exact location of her wreckage remained unknown for over 150 years because of difficulties in reaching the area, which is extremely inhospitable and frequently iced over.[6]
Oral traditions of theInuit tell stories of the ship. The abandoned ship was a source of copper and iron for the indigenous people in the area; metal nails were missing from smaller boats on the shore when they were discovered.[6] One Inuit account from 1910 noted that "one year she had still been on the beach and the next year she was gone without a trace."[7] When Canadian anthropologistVilhjalmur Stefansson reachedMercy Bay during his1915 voyage to the Arctic, he failed to find her remains.
After meeting the Inuit who made pilgrimages to the wreckage, he suggested a link between theInvestigator's stranding and the absence ofmuskoxen onBanks Island. He speculated that the Inuit had killed off the animals for food during their journeys to and from the wreckage over the 40 years since abandonment. The muskoxen have since repopulated the island and now number nearly 50,000.[8]
In July 2010, a team ofParks Canada scientists, archaeologists, and surveyors began searching for the sunken wreck of theInvestigator in Mercy Bay at the northern tip ofAulavik National Park. It was the first expedition to specifically search for the ship.[9][10] The team arrived onBanks Island in theBeaufort Sea on 22 July and began a sonar scan of the area three days later, based on the originalRoyal Navy records of the position of the ship when it was abandoned.[6][11] Its remains were quickly discovered, 150 m (490 ft) off the north shore of Banks Island, with the deck of the ship about 8 m (26 ft) below the surface.
According to a superintendent with Parks Canada, the ship was found "sitting upright in silt; the three masts have been removed, probably by ice."[12] Her hull lies partially buried in silt and the cold Arctic water has prevented the outer deck from deteriorating quickly. There are no plans to raise the ship's remains, although the team did send aremotely operated underwater vehicle to take photos and assess the wreckage.[6]
