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 2009 ca. 92.7% of the target area (ca. 300,000 km2) has been surveyed except very shallow coastal area (so called white zone). Since its first series total of 20 series of map sheets (ca. 87% of total planned maps) have been published. As being the second of the three-year (2010 to 2012) program the southern part of the planned area offshore Ulsan was surveyed. Geographically it is located between 35°00’ N and 35°30‘ N in latitude and between 129°00’ E in longitude and the exclusive economic zone boundary between Korea and Japan. The areal extent is approximately 4,000 km2. The achieved survey data and thematic maps will be compiled with the others of 2010 and 2012. This report is a brief summary of the second-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) and the R/V Tamyang of the Pukyong National University were used. During the geophysical survey approximately 970 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 97 cored 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 XXI (Ulsan Area)’ comprised of six map sheets on seafloor bathymetry, seafloor geology, acoustic character, total thickness of sedimentary strata, magnetic and gravity anomalies. For continuing map supply service one of the sold-out maps, the Base Map of Submarine Geology of the Korean Continental Shelves, Series IX, 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.
