« The Captain's cabin is the best preserved space of the entire lower deck. Parks Canada’s Underwater Archaeology Team discovered that a significant amount of sediment has seeped through the stern gallery windows, covering a good portion of the artifacts and likely preserving what lies beneath. The Captain’s desk, map cabinets with drawers closed, boxes that most likely contain scientific instruments, a complete tripod (similar to a surveyor’s tripod) and a pair of thermometers were identified. The only space on the lower deck that remains inaccessible is the Captain’s sleeping quarters, behind the only closed door on this deck.
Parks Canada expects that there is a high probability of finding written documents that have been sealed within these areas of HMS Terror because the environment would be preserving them in a near perfect state. With a water temperature of 0 degrees Celsius or lower and an internal environment with no natural light, artifacts have been essentially frozen-in-time for approximately 170 years. »
