In the last full episode of the season, we travel to the Greenland ice sheet and hear from a researcher who collects data at the face of tidewater glaciers, studying the turbulent zone where freshwater meets and mixes with seawater. This episode emphasizes the transition of solid ice into liquid freshwater, occurring globally, due to increasing temps, and shares why loss of the frozen reservoir matters.
topics and purpose: scene-setting in Greenland, transition and movement of water molecules globally as part of the interconnected hydrological cycle, increasing temperatures and glacier melt events due to anthropogenic climate change, research methods on ice and at the glacier-ocean interface, the global significance and utility of glaciers, balance, wrapping up the season
terms defined: freshwater reservoir, seismology, sonification, geophones, icequakes
