Ce que couvre cette vidéo
Pedro Duarte, a Portuguese oceanographer based in Tromsø, Norway, describes his research at the Norwegian Polar Institute (NPI) and the iC3 Polar Research Hub.1:26 The NPI, headquartered in Tromsø roughly 300 km north of the Arctic Circle, employs about 150 staff under Norway's Ministry of Environment and Climate and has operated for over 100 years.2:05 Duarte explains the institute's multidisciplinary scope: glaciologists, physical and biological oceanographers, and geologists study Arctic and Antarctic systems, with particular focus on glacier retreat, sea-ice dynamics, and the albedo effect of snow-covered ice on global climate.17:32 Polar bear encounters, extreme cold, icing on equipment, and the high cost of ships and helicopters make Arctic fieldwork hazardous and expensive.24:08 The iC3 Center for Ice, Cryosphere, Carbon and Climate is a Norwegian-funded research hub based at the Arctic University of Norway in Tromsø, partnered with the NPI, running on a rare 10-year budget cycle.35:59 Its core focus is the seafloor exposed as glaciers and Antarctic ice sheets retreat — terrain difficult to study beneath hundreds of meters of ice.34:22 Duarte co-leads iC3's mathematical modeling component, which projects future cryosphere-climate interactions to inform policy.36:32 The conversation also touches on the UN's 2025 International Year of Glaciers.18:13
