Polar regions are under-sampled due to their remote, harsh and dynamic environments. Long-term attended measurements are impossible due to the weather conditions, and unattended monitoring is hampered by the dynamic environment i.e. when holes in the glacier are cut to deploy instrumentation to monitor the ocean below, the water in the hole quickly refreezes, making it impossible to recover the instruments or data. RBR has been manufacturing equipment for nearly 50 years and has leveraged this experience to develop tailor-made polar solutions for a number of research organizations. Expanding the capability of both the inductive modem system, and the RBRcervello, the brains of the operation, RBR has delivered solutions to allow continuous, multi-year, real-time, unattended monitoring in the polar regions. The entire solution includes a jacketed steel cable that the modem-enabled instruments are clamped to, with the RBRcervello at the surface. The sub-surface modems transmit data inductively to the RBRcervello, which in turn captures, translates, and telemeters the data. Efficient electronics and compact sensors, which can operate in freezing temperatures, allows data to be collected over extended periods, i.e. multiyear, at high-temporal resolution. Adding water quality sensors to the RBR CTDs and integrating the Nortek ADCPs to the system, expands the capability of the solution further, broadening the scientific outcomes. This paper will focus on the technical developments RBR utilized, the rationale behind these, the solution delivered and most importantly, the increased capability for the research organizations who have recently deployed these systems in the polar regions.
