High-Quality Observation Data from the Ieodo Ocean Research Station: Management and Global Accessibility

The Ieodo Ocean Research Station (I-ORS), located southwest of Jeju Island, South Korea, is a remote offshore structure that has been monitoring  15 ocean and atmospheric parameters since 2003. Key parameters, including water temperature, salinity, air temperature, wind direction, wind speed, relative humidity, and atmospheric pressure, are measured at 10-minute intervals. These data are subjected to stringent quality control processes to ensure scientific validity and precision. The quality control process follows OOI (Ocean Observatories Initiative) protocols, employing automated checks such as physical limit verification, variability (standard deviation) analysis, spike detection, and constant value checks. These checks assign initial flags to identify potential anomalies. To further enhance data reliability, manual inspections are conducted, reviewing oceanographic conditions and maintenance reports of facilities and equipment. Flags are adjusted accordingly to refine the data's accuracy. The quality-controlled datasets, accompanied by metadata, are registered on international platforms such as OceanSITES and SEANOE. These platforms provide free access to the global scientific community, supporting diverse research areas such as oceanography, climate change studies, and atmospheric sciences. The Ieodo station's high-quality data contribute significantly to advancing scientific understanding of oceanic and atmospheric phenomena and fostering collaboration within international observation networks.
