This report describes the sixth field season of a multi-year Parks Canada-led search for the wrecks of HMS Erebus and HMS Terror, lost during the Sir John Franklin Expedition of 1845 in search of a Northwest Passage. As well, it describes the September 2014 discovery of the wreck of HMS Erebus. At the outset of the 2014 field season the survey aimed to locate the remains of Franklin’s two missing ships using marine remote sensing. The discovery of Erebus during the first week of September 2014 immediately shifted the project aims to an evaluation of the structural and commemorative integrity of the site, assessment of its environmental conditions, and a preliminary inventory of exposed structures and artefacts. The wreck is part of The Wrecks of HMS Erebus and HMS Terror National Historic Site and is co-managed by Parks Canada and Inuit. This report, completed in 2015, has since been translated into French and Inuktitut and is published here.
