The goal of this undertaking is to find artifacts that tie to the Franklin Expedition of 1845. The main artifacts sought after for this mission relates to finding a container that holds the written records made by those doomed men, or the buried coffin location of Sir John Franklin himself. No one knows if either of these entities exist. The existence of Sir John's tomb is not as probable as one might hope because anything that might stand out from a standing visual sight line on the ground would have seemingly already been found by any one of the previous searches that have already been conducted there by others. But that would assume one is looking in the usual places. Will NOT only be looking there. And should something exist and is buried in colder dirt, sand and rock, “on the land”, it is not only possible, but probable, that it would show up on the thermal camera from the air.

Planning includes flying over areas of King William Island to thermally and visually examine the topography for potential signs of a tomb, earth cavity of ice or hollow, or any anomaly that may be still frozen underground - where surrounding grade tundra or rock may be ice free and slightly warmer during a warm summer arctic day. On the left is a photo of John Hartnell, one of the first 3 to die on the Franklin Expedition. He died on January 4, 1846 and is here almost as he appeared then - frozen in time.
The key to the theory on how to find it - The ground surrounding a target will thermally image slightly WARMER (red/yellow) on the sensing spectrum than the section of terrain that is partially frozen or the sub terrain ice that it might be encapsulated in, which would image slightly COLDER (blue).

The thermal camera has a very sensitive imager which detects a 1 degree heat differential from as far as 10,000 feet away. The camera will be custom mounted in the belly of DeHavilland Beaver airplane and exposed to the elements through a custom built cone integrated in the cargo drop hatch door. Potential targets will be recorded by GPS coupled to the camera imaging system to facilitate ground searches with metal detection devices (including magnetometer) which include coil and blanket antennae configurations.
