Read the following passage carefully:
Before Dr. Maya Lin embarked on her 2018 expedition to the Antarctic Peninsula to sample subglacial meltwater, she spent two years synthesizing satellite telemetry collected during the 2012 Polar Sentinel mission. Her interest in subglacial hydrology had actually been sparked years prior, when she read Dr. Alistair Vance’s 2004 seminal paper on sub-ice lakes while completing her undergraduate thesis in 2007. Upon arriving at McMurdo Station in early 2018, Lin discovered that her primary drill rig had suffered severe mechanical failure during transit—a setback reminiscent of her failed 2015 pilot study in Greenland, where extreme weather destroyed her temperature sensors. Rather than aborting the 2018 mission, Lin pivoted to deploying autonomous thermal probes, a technique she had perfected while consulting for a deep-sea geothermal project in 2016. By late 2019, after analyzing the data recovered by the thermal probes, Lin published her landmark study proving the existence of interconnected subglacial rivers.
