Design and analysis of deepwater tension sensors for ice drill application

open access: yesAnnals of Glaciology, 2021
Monitoring the tension in cables is significant in some ice drill and deepwater applications. Take our RECoverable Autonomous Sonde (RECAS) for example. It is able to melt a hole to the bottom of ice sheet and is able to move upwards.
