## Summary

Dr. Sridhar Anandakrishnan, a geoscience professor at Penn State with an electrical engineering background, discusses deploying scientific instruments in Antarctica and Greenland. He details the design of the 'GeoPebble,' a wireless seismic sensor that uses a Parallax Propeller microcontroller and Wi-Fi to avoid cable failures in crevassed terrain. The conversation also covers a sonic logger instrument that transmits 128-volt pulses through ice to measure crystal orientation, and concludes with a discussion on The Boring Company's tunneling technology.
