The Bjurälven cave is Swedens longest underwater cave and each year a team of cavedivers are exploring and mapping the cave system. The expedition is taken place in winter due to the regulations in the nature reserve area, this means that the divers needs to handle water temperatures close to 0 degrees celsius and air temperatures down to -20.
