Abstract

Procedures involved in the refinement of the regional geoid for the area encompassing the Korean peninsula and the East Sea are described, and the computational results are provided. A comparison between the geoid height data, the mean sea surface height and the final product of the refinement work is provided and analyzed. The regional marine geoid thus refined seems to have a better resolution, in terms of its correlation with the bathymetry, and shows the bottom features in a more detailed manner when compared with previously used procedures. The general pattern of the computed geoid profile matches reasonably well with the existing studies, where the correlations between the refined regional marine geoid and the bathymetry are (1) 0.44 for the area $117{\sim}142.5^{\circ}E/24{\sim}52^{\circ}N$ and (2) 0.47 for the area $127{\sim}142.5^{\circ}E/32{\sim}50^{\circ}N$ in the East Sea respectively.

한반도와 동해를 포함하는 지역적인 지오이드를 세밀화하는 과정을 설명하고, 계산 결과를 제시하였다. 지오이드의 높이와 해수면의 높이의 비교와 최종적인 세밀화의 결과를 해석하고 제시하였다. 세밀화된 지역적인 해양 지오이드는 이전에 보고된 것과 비교하여 더 나은 해상도를 가지며 해저수심과의 상관성을 갖는다. 산정된 지오이드의 일반적인 패턴은 기존의 연구와 잘 일치하며, 동해에서의 세밀화된 해양 지오이드와 수심과의 상관관계는 (1) $117^{\circ}E{\sim}142.5^{\circ}E/24^{\circ}N{\sim}52^{\circ}N$의 영역에서는 0.44, (2) $127^{\circ}E{\sim}142.5^{\circ}E/32^{\circ}N{\sim}50^{\circ}N$의 영역에서는 0.47이다.
