The 'Marine Geological and Geophysical Mapping of the Korean Seas' is a government program launched and funded by the Ministry of Knowledge Economy in 1975. The main objectives are to achieve basic knowledges and to develop better understandings on the origin, character, evolution and economic potential of the geologic strata in the mapped area. Another important objective is to promote human resources and technical infrastructure for exploring marine mineral and energy resources.
Major output is regional scale (1:250,000) thematic map sheets of the surveyed area published in one- to three-year interval. As of 2012 ca. 96% of the target area (ca. 350,000 km²) has been surveyed except very shallow coastal area (so called white zone). Since its first series total of 21 series of map sheets (ca. 99.5% of total planned maps) have been published.
As being the first of the three-year (2013 to 2015) program, the southern sea of Dokdo was surveyed. Geographically it is located between 36°10′N and 37°N in latitude and between 130°5 0′E in longitude and the exclusive economic zone boundary between Korea and Japan. The areal extent is approximately 6,000 ㎢. The achieved survey data and thematic maps will be compiled with the others of 2014 and 2015.
This is a brief summary of the first-year activities with the emphasis on the results of the three geophysical and geological surveys made onboard. The R/V Tamhae II of Korea Institute of Geoscience and Mineral Resources (KIGAM) was used to acquire the data. During the geophysical survey, approximately 1,250 line-km records were acquired using single-beam and multi-beam echo-sounders, a 3.5-kHz chirp acoustic profiler, a digital multi-channel air-gun seismic system, an onboard gravimeter, and a towed magnetometer. During the geological surveys, 10 boxcore samples were recovered for confirming the chirp seismic interpretation and evaluating the spatial distribution of the sedimentary texture and acoustic properties.
The survey results will be included in the dataset to be used for publishing the 'Marine Geological and Geophysical Maps of the Korean Seas, Series XXII (Dokdo Area)' comprised of seven map sheets on seafloor bathymetry, seafloor geology, acoustic character, total thickness of sedimentary strata, magnetic anomalies, gravity anomalies, and geoacoustic map. For continuing map supply service one of the sold-out maps, the Base Map of Submarine Geology of the Korean Continental Shelves, Series VI, was republished. The published maps will expectedly be an essential guide to understand the geological and geophysical characters of the submarine strata in the Korean seas in regional scale.
