摘要:
本文作者所在单位1988年在舟东共测得地磁剖面67条,剖面总长度为2978km。根据测网中306个测线交点上交点差的方均根值,确定精度为3nT,这次测量是东海陆架区油气勘探调查的一部分。

GEOMAGNETIC SURVEY EAST OFF THE ZHOUSHAN ISLANDS IN THE EAST CHINA SEA
Abstract:
Cruise measurement of the geomagnetic field total intensity in the area east off the Zhoushan Islands in the East China Sea was made in 1988. Atotal of 67 profiles were obtained ranging a distance of 2978 km. The network accuracy, estimated by the square mean root of the discrepancies at all 306 track crossover points, was 3nT(nanotesla). This was a part of the project of oil-gas prospecting in the East China Sea shelf.
