Episode notes
Life on a Research Vessel
- Ravenna Koenig spent five weeks on a Russian research vessel, longer than a football field, with 80 other people.
- They had limited communication, shared cabins, and spent time on deck observing polar bears and the Northern Lights.
Arctic Warming and Sea Ice
- The Arctic is warming twice as fast as the rest of the world, causing sea ice to shrink and thin.
- Scientists on the MOSAiC expedition aim to understand this change and its consequences.
Ocean Salinity and Ice Melt
- Ocean physicist Tim Stanton studies how salinity differences in the ocean affect sea ice melt.
- Fresher meltwater trapped at the surface absorbs more heat, potentially accelerating melting.
