Research Vessel OverviewR/V JANGMOK No.2
“Jangmok” is the name of a town in the northeastern region of Geoje Island, where the South Sea Research Institute, the home port of the research vessels, is located. After the RV Jangmok, a second small research ship named the RV Jangmok 2 was built as well.

R/V Jangmok No.2Research Equipment
A basic device mounted on the research vessel that continuously observes the surface temperature, salinity, and sound velocity of the water while the research vessel is in motion. The thermosalinograph is installed in the bow thruster room, and a remote water temperature sensor has been mounted on the seawater inflow line, increasing the reliability of the data collected.
A comprehensive oceanographic observation device designed to measure the basic physical parameters of conductivity, temperature, and depth. The device transforms analog signals from CTD sensors into digital data and uses single-conductor CTD cables to read and store the data in real time on the research vessel. Optional sensors, such as a transmissometer, fluorometer, PAR (irradiance) sensor, or altimeter, may also be mounted on the device, which collects seawater samples in 24 10-liter Niskin bottles.
A sensor that provides real-time measurements of the sound velocity of the water surface on a moving or stationary vessel using the EM710 Multibeam Echo Sounder.
A device that measures the sound velocity of each water layer and stores the data, which can then be downloaded to a computer using dedicated software. Acquired data are processed and used to facilitate the movement of devices that use sound waves, such as multibeam and other types of echo sounders.
A device that measures the velocity and volume of ocean currents over a range of depths using the fact that changes occur in the frequency of a sound wave produced by a moving source, known as the Doppler effect. The profiler operates at the frequency bands of 38 kilohertz and 150 kilohertz, which are effective at depths of up to 1,000 and 400 meters, respectively.
A device that emits and receives sound waves in order to accurately calculate the distance to the ocean floor.
A device that emits sound waves from a vessel and receives the sound waves that are bounced back from the seabed as a means of observing and recording water depth and the landscape of the seabed. Unlike existing echo sounders, which can take measurements at only a single location immediately below the vessel, the device produces a swath of depth measurements and readings within the sound wave emission and reception range of the device. The information collected by the multibeam echo sounder is transmitted to a computer onboard the vessel, which then produces a bathymetric map or a contour map with relevant colors and graphics in real time. The data gained from each ping is separated into different types of information, and the device can take measurements at a maximum depth of 2,000 meters underwater.
A device for acquiring high-resolution images and data on multiple layers of sediment and rocks under the seafloor. The profiler emits sound waves with the frequency range of two to seven kilohertz, processes the signal reflected back from the ocean floor and sub-bottom layers of the ocean floor, and provides information on the strata of the ocean floor. This device is especially useful for surveying sub-bottom layers of the ocean floor in preparation for the construction of cross-sea bridges and offshore structures and the installation of submarine cables.
A GPS and positioning system that provides accurate, real-time location information for the research vessel and the mounted research equipment it operates. It also corrects the attitude data of the vessel. For higher accuracy, the device uses DGPS (Differential Global Positioning System), based on which it receives GPS signals from satellites as well as signals from ground-based reference stations through beacon receivers that allow for the correction of positioning errors. The Seapath 200 system installed on the RV Onnuri receives signals not only from ground-based reference stations but also from satellite reference stations, allowing the crew to minimize navigation errors when cruising in the ocean.
A device that receives location information from ground-based reference stations around the world through DGPS antennas and then provides the GPS data necessary for the operation of research equipment.
A device that measures the vessel’s roll, pitch, and heave and provides attitude information necessary for the operation of research equipment.
