What this episode covers

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.

    Episode 59: Robots at sea - Ffion Llewellyn

    Ffion Llewellyn, an engineer at Oshen, explains how the startup is building autonomous micro-vessels for remote ocean sensing. She details the integration of hydrophones from Aris Aqua and HydroMoth, as well as metocean sensors, to monitor marine mammals and weather data. Llewellyn discusses the engineering challenges of waterproofing and robustness, noting that water ingress often causes components to fail during sea trials. The company is currently in the early stage, having completed sea trials with two prototypes in Cardigan Bay and planning to deploy a fleet of ten.
