Experts speculated that the wreck rested on flat terrain at around 3,000 metres, undisturbed by massive sediment disposition and little to no erosion.[22] According to Julian Dowdeswell of the Scott Polar Research Institute, the known conditions on the sea bed suggested that Endurance should not be damaged and that it would likely be in the same state as it was when it sank in the pack ice in 1915. He also noted that any future attempts at finding the Endurance would be "add-ons" to other main scientific expeditions to the area, such as the one in 2019, which was launched chiefly to study the melting and retreat of the Larsen ice shelves.[22]
