ROVs are unmanned vessels that give scientists the opportunity to study and collect organisms from greater depths than manned submersibles, without the risk to human life, and at less expense and effort. ROVs are becoming the primary tool for studying the biodiversity of the deepest oceanic ecosystems and are a key technology in Census research. They are linked to a surface support research vessel that controls their underwater activity and transports them to and from the research site.
