We owe Dr. Clark Richards and RBR big time. If it wasn’t for their help and generosity we wouldn’t of had the CTD (conductivity, temperature, depth probe) needed to collect data for NASA; this year or last year. Professional grade scientific equipment is very expensive, especially if you want to lower it deep in the water. The deeper you want to lower a probe the stronger it has to be to handle the pressure, so the price increases. It’s the same with our sonar system, deeper = more expensive. The fjords in Greenland can be thousands of feet deep; our equipment has to be capable of handling those depths.
