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.
