초록

국립해양조사원이 1999년도 '해양2000'호를 이용하여 측정한 서해 남부지역의 선상 중력자료를 처리하였다. 자료처리 결과 264개 교점에서 고도이상의 RMS는 0.436mGal로 매우 좋은 결과를 나타내고 있다. 국립해양조사원이 '해양2000'호를 이용하여 측정한 선상 중력은 우리나라 일원의 중력관련 연에 매우 큰 기여를 할 것이다.

In this study, a series of data processing methods to calculate gravity anomaly from observed marine gravity data by NORI(National Oceanic Research Institute) using RV 'Hayang2000' in 1999 at southern part of the yellow sea were developed. As a results, the RMS difference of Free air anomaly among 264 crossover points is 0.436 mGal. The shipborne gravity data by NORI using RV 'Haeyang2000' will be very useful for gravitational research in and around Korean peninsula.
