Log Post: Duties of a Principal investigator

By definition, every ship has a captain whose job is to decide, order and know. Every seagoing expedition requires another person who works closely along those lines, but on the science-side of things. The principal investigator, or “PI,” is in the limelight of the expedition – handling, deciding, and managing everything that happens in terms of the … Continued

Log Post: East Meets West: The Cutting Edge of the Pacific Plate

  The island archipelago of Tonga sits at the junction of two major tectonic plates – the Indo-Australian plate in the west and the Pacific Plate in the east. It is part of the Pacific “Ring of Fire” that encircles the entire ocean basin. The oceanic crust of the Pacific Plate was born at a … Continued

Page: 4500 m Remotely Operated Vehicle (ROV SuBastian)

Our underwater robotic research program includes a Remotely Operated Vehicle (ROV SuBastian) depth rated to 4,500 meters with research capabilities for use on R/V Falkor (too). The ROV is outfitted with a suite of sensors and scientific equipment to support scientific data and sample collection, as well as interactive research, experimentation, and technology development. ROV Frequently … Continued

Log Post: Video: The Survey (Part1)

Experience how the teams onboard R/V Falkor work with the Remotely Operated Vehicle to make the goals of the mission come together, gathering beautiful imagery and ground-breaking data far beneath the surface of the sea. ‪

Log Post: Underwater Interplay: Cameras and Fibers

  One of the primary focuses on this research cruise is to systematically photograph an area of approximately 25 football fields with a resolution that would allow us to see individual blades of grass. To achieve this efficiently, we have designed a special camera system. During the first days of transit, the ROPOS crew set up … Continued

Log Post: 3D Seafloor Mapping with Structured Light

  One of the primary goals of this research cruise is to create high resolution 3D maps of vent groups found in Tongan waters. For this purpose, the remotely operated underwater vehicle ROPOS has been equipped with additional sensors during the transit to the Niua Volcanic Complex – these sensors will allow us to map … Continued

Log Post: Biologist on Board, Vents Ahoy!

  Deep-sea hydrothermal vents harbour unique animals that rely on reduced chemicals emitted from the vents to survive. A mile below the surface of the ocean, in complete darkness and at high pressure, these animals thrive in an environment characterised by hot, acidic and sulphurous fluids. Since their discovery in the 1970s, many vent fields … Continued

Log Post: It Takes a Village to Start a Research Cruise

  It Takes a Village to Start a Research Cruise (or “A Light-hearted look at the Voyage to the Vents”) Boarded the ship on Friday, left the port of Suva on Sunday, and arrived at Niua Volcano to start our work Tuesday morning… That’s four days! Plenty of time for waiting around, relaxing, working on … Continued
