ROPOS ROPOS ("Remotely Operated Platform for Ocean Science") is an ROV used primarily for scientific research. It was originally build in Vancouver by International Submarine Engineering and purchased by the Canadian federal government. The same government program also operated the "Pisces IV" manned submersible, now in Hawaii being run by the Hawai'i Undersea Research Laboratory (HURL) who found the long-lost two-man Japanese sub which heralded the attack on Pearl Harbor.
