About RBR Since 1973, RBR has been designing and manufacturing oceanographic instruments in Ottawa, Ontario to measure our blue planet. The effects of climate change are being seen from the ocean’s abyss to the polar ice caps and our sensors quantify this change to support better analysis, improved planning, and more effective mitigation strategies. Our instruments measure water parameters in some of the harshest environments on the planet! They are mounted on underwater drones, dropped out of planes, and sent to the bottom of the ocean – sometimes for years at a time – all in an effort to get precise and accurate data to support climate research! We have been fortunate to be able to partner with some of the world's leaders in the field of ocean science, like Fisheries and Oceans Canada, The Scripps Institution of Oceanography, The Woods Hole Oceanographic Institution, The Norwegian Polar Institute, and The British Antarctic Survey, just to name a few!
