Abstract. The oceanic region at the terminus of tidewater glaciers is under-explored, yet the processes occurring there are critical to our understanding and assessment of climate-change-induced ice loss. This region is hazardous for humans to directly access, necessitating exploration using unmanned robots. This paper discusses the design, development and deployment of a low-cost remote-controlled surface vehicle for in-situ studies in the near-terminus region. The robot is instrumented with passive acoustic, conductivity-temperature-depth and video recorders, and is able to successfully profile short transects in the proximity of, or even at, the terminus region.

Short summary
The boundary between the ocean and the terminus of marine-terminating glaciers is under-explored, but holds the key to understanding many climate-change-induced processes. This region is too hazardous for humans to directly access, but unmanned robots can help us safely explore it. Here we present the design, development and deployment of a low-cost, modular, robust surface robotic system to study the near-terminus region, and improve our understanding of the climate-change mechanisms there.
