““Karl’s doctoral thesis focused on how newly calved icebergs affected global sea currents as they dissolved. Over the last four weeks, he and Steve had deployed high-tech buoys around the iceberg that measured sea temp and salt-water/fresh-water balance as well as took periodic sonar readings of the iceberg’s changing shape. The goal was to learn more about how icebergs disintegrated after leaving Antarctica. Antarctica held ninety percent of the world’s ice, and when it melted in the next few centuries, it would dramatically change the world. He hoped his research would shed light on exactly how.””
