🦭 Seal Blubber and Cold Water Lab: Heat Loss, Insulation and the Diving Reflex

Heat flows from a seal's warm core through a blubber layer into near-freezing water: cylindrical-shell conduction, Newton cooling, lower critical temperature, the diving reflex, flipper counter-current exchange and an infrared view.

Follow heat from a seal's warm core through a blubber layer into near-freezing water: cylindrical-shell conduction, Newton cooling with a convective film, lower critical temperature, the diving reflex, flipper counter-current exchange and an infrared view, compared across harbour, Weddell and elephant seals, a walrus, a pup and a diver in a wetsuit.
