Mission

Technology drives discovery at Schmidt Ocean Institute, transforming how we explore and understand the ocean. From high-resolution mapping systems to robotic platforms and integrated data tools, these innovations enable precise observation and analysis of the ocean environment.

Designed for flexibility, RV Falkor (too) can support a wide range of scientific objectives, adapting its technologies and systems to meet the needs of each science expedition. By making these capabilities available to the scientific community, we accelerate discovery and foster global collaboration in ocean science.

Sonar Systems

R/V Falkor (too) was designed to maximize sonar performance through specialized hull features that reduce acoustic interference in challenging sea states. The vessel’s large sonar gondola, integrated during the original refit, lowers the sonar arrays below the primary hull-water interface to shield them from bubble sweep and turbulence, improving data quality in rough conditions. After several years of operational experience, the vessel was further enhanced in 2025 with the addition of the “Science Bow,” a modification that changed the shape of the bow, significantly reducing bubble entrainment along the hull in heavy weather. Together, these design features expand the range of sea states in which high-quality mapping can be conducted, increasing efficiency and effective use of ship time.

  • Multibeam

    Multibeam sonars create detailed imagery of the seafloor by sending out fans of sound pulses beneath the ship. By calculating the time it takes for each pulse to bounce back, the system determines the depth at many points across the seafloor, building a three-dimensional map below the ship nearly instantaneously. Different multibeam system designs allow for mapping at different depths - some provide extremely high detail in shallow water, while others can reach much deeper with broader coverage. R/V Falkor (too)’s multibeam sonars work together across this range, delivering high-resolution seafloor mapping wherever the ship operates, from shallow coastlines to the deepest ocean trenches.

  • ADCP

    Acoustic Doppler Current Profilers (ADCPs) measure the speed and direction of water currents by sending sound waves into the water and listening to how particles in the water scatter the sound. By analyzing the change in frequency of the returned echoes (the Doppler shift), the system can calculate how fast and in what direction the water is moving at different depths.

    Shallow ADCPs capture detailed currents near the surface, while deeper systems provide broader coverage at greater depths. R/V Falkor (too) carries both, recording currents at a depth range from just below the ship down to 1,000 meters, providing a complete picture of ocean circulation from the upper water column to the upper deep sea.

  • SBP

    A Sub-bottom Profiler (SBP), uses low-frequency sound pulses to penetrate beneath the seafloor and probe the underlying sediment and rock layers. As the pulses travel downward, each boundary between layers reflects distinguishable signatures of the sound back to the ship. By analyzing the timing and strength of these reflections, the system produces a detailed cross-section of subsurface layers and can provide information on their composition, such as distinguishing between soft sediments and harder consolidated layers.

    On R/V Falkor (too), the SBP29 is used across the full depth range of the ocean, from shallow water to the deepest trenches. It is commonly used to characterize seafloor substrate and sediment structure, and can also reveal subsurface features such as methane pockets beneath the seafloor. The system can be synchronized to ping alongside the multibeams during acoustic surveys, allowing sub-seafloor information to be collected concurrently with seafloor mapping.

  • Depth Sounder

    Single-beam depth sounders measure water depth by transmitting a focused pulse of sound directly beneath the ship and timing how long it takes for the echo to return from the seafloor. Using the known speed of sound in seawater, this travel time is converted into an accurate depth measurement at a single point directly below the vessel.

    R/V Falkor (too) primarily relies on its multibeam systems for comprehensive seafloor mapping. The depth sounder serves as a backup depth-measurement system, providing reliable, straightforward depth data along the ship’s trackline when needed to support navigation and ongoing science operations.

  • Hydrophone

    Hydrophones monitor underwater sound by measuring the presence and intensity of sound across a range of frequencies. Rather than recording audio, it analyzes the frequency of the sound field, allowing specific sound signatures to be identified.

    On RV Falkor (too), this capability supports the detection and study of marine life that produces characteristic sounds. Operationally, the system is used to monitor the ship’s acoustic environment, track noise generated by the vessel and other onboard sonar systems, and help explain interference or noise observed in sonar data.

  • Sound Velocity

    Sonars determine distance, depth, and position by measuring how long it takes for a sound pulse to travel through the water, reflect off a target, and return to the sensor. Accurate sound speed measurements are critical to sonar operation, as even small errors in sound speed can result in significant errors in range, depth, and angle calculations.

    On R/V Falkor (too), sound speed is continuously monitored and updated using multiple complementary methods to ensure the highest data quality. A live sound speed sensor at the sonar faces provides real-time measurements for beam steering. Expendable probes (XBTs) supply temperature profiles that can be referenced to sound speed, offering regular updates to water column conditions in the upper water column, without interrupting other operations. In addition, sound speed profiles derived from CTD and ROV downcasts and upcasts are routinely applied, ensuring the sonar systems use the most current and representative sound speed information available.

    CTD Seabird 911 System

    The Sea-Bird SBE 911plus CTD derives sound velocity using high-accuracy measurements from dual SBE 3plus temperature sensors, dual SBE 4C conductivity sensors, and a Digiquartz pressure sensor, calculating full-depth sound speed profiles for precise acoustic timing and correction.

    ROV installed Seabird SBE49 and Valeport uvSVX

    On the ROV, sound velocity profiles are obtained using a combination of a Sea-Bird SBE-49 FastCAT CTD, which derives sound speed from high-accuracy temperature, conductivity, and pressure measurements, and a Valeport uvSVX, which directly measures sound velocity using time-of-flight technology, providing complementary, high-resolution sound speed data throughout the water column.

  • Fish Finding Sonar

    The EK80 echosounder uses sound to detect and characterize targets in the water column, such as fish, zooplankton, and other scattering organisms. By transmitting sound pulses and measuring the strength and timing of the echoes that return, the system can determine the depth, distribution, and relative abundance of organisms between the surface and the seafloor.

    The EK80 operates across multiple acoustic frequencies (18, 38, 70, 120, 200, and 333 kHz), with each frequency interacting differently with organisms of varying sizes and compositions. Lower frequencies penetrate deeper and are better suited for detecting larger targets, while higher frequencies provide finer detail and improved sensitivity to smaller organisms. Using multiple frequencies together allows researchers to distinguish between different types of marine life and better interpret the structure of the midwater ecosystem.

  • Uncontaminated Seawater

    R/V Falkor (too) provides an uncontaminated seawater system designed specifically for scientific use. Seawater is drawn from an intake located approximately 5.3 meters below the waterline on the port bow, minimizing contamination from the ship’s hull and surface influences. The intake passes through a coarse strainer to protect pumps from large debris before being distributed throughout the vessel.

    The system is configured as two independent plumbing circuits, allowing scientists to operate duplicate sensors or maintain redundant seawater supplies when required. This design supports continuous flow to scientific instruments while providing flexibility for cruise-specific needs.

Emergency System

The AUV is equipped with multiple autonomous safety and recovery features designed to protect the vehicle in extreme or unexpected situations. These include obstacle avoidance and terrain assessment capabilities, as well as redundant emergency systems such as drop weights, flotation deployment, emergency GPS positioning, and backup acoustic beacons to support vehicle recovery if normal operations are compromised.

Landers

Subsea landers are platforms that operate independently of the ship, using ballast to remain on the seafloor for extended deployments. At the end of a mission, an acoustic release drops the weight, allowing the lander to return to the surface for recovery. These landers can be outfitted with cameras, traps, pumps, and other instruments to collect time-series observations and samples before being retrieved by the ship.

  • Fume Hoods

    RV Falkor (too) is equipped with three Esco ductless fume hoods (two in the Main Lab, one in the Wet Lab). These hoods do not exhaust externally; instead, they rely on a carbon filter paired with a secondary specialty filter configured for a specific chemical class—typically aldehydes, acids, or VOCs. As ductless hoods depend on filter performance and do not provide continuous breakthrough verification, chemical use must align with the installed filter configuration and its operational constraints.
