Heat loss to the habitat atmosphere is significant in saturation diving. Heat is lost to the ambient gas in a closed diving bell, saturation accommodation and decompression chambers, and underwater habitats, particularly when there is a helium component to the gas, due to the high thermal conductivity of helium.
