daily temperature measurements at our research stations in the Arctic and Antarctic, monitoring ocean currents at our deep-sea moorings in the Fram Strait and the Weddell Sea, and the data from our sea-ice buoys drifting through the Antarctic and Arctic Oceans, as well as the data supplied by various satellites, without which modern climate research would be practically impossible. Whether for the ocean, ice, atmosphere or land: our efforts provide reliable data that is absolutely essential for the validation of our climate models
