초록

현행 중등학교 과학 및 지구과학 교과서에 제시되어 있는 대부분의 해류도는 1930년대 일본 과학자에 의한 대규모 해양 관측을 기반으로 제작된 것이다. 현재 해양학자들의 과학적인 관점으로 보았을 때 이 해류도들은 상당한 오류를 가지고 있고 학생들에게 오개념을 유발할 가능성이 높아 새로운 해류도 제작이 필요하였다. 그러나 황해와 동중국해의 해류는 상대적으로 얕은 수심과 복잡한 지형, 바람, 조류의 영향으로 계절적으로 복잡한 양상을 나타내기 때문에 하나의 해류도로 표현하는 것은 간단하지 않다. 이 문제를 해결하기 위하여 황해 및 동중국해의 해류도 작성에 유의해야 할 주요 항목으로 쿠로시오해류의 동중국해로의 유출입과 북상 경로, 대마난류의 기원과 대한해협으로의 유입, 대만난류의 경로, 제주난류, 양쯔강 유출류의 흐름 양상, 황해 난류의 북상 범위와 경로, 그 외 중국연안류, 한반도 서해안의 서한연안류, 보하이해 해류 등 16가지를 선정하여 이에 기반을 두고 학회의 의견을 수렴하였다. 2014년부터 3년 동안 학회, 전문가 토론회, 자문회의를 통하여 해양학계 과학자들의 오랜 기간 동안 심도 있는 논의와 여러 차례 수정을 통하여 황해와 동중국해에 대한 최종 해류도를 제작하였다. 최종 해류도는 이 해역 해류의 복잡성을 고려하여 여름과 겨울을 대표하는 해류도, 여름과 겨울의 표층과 저층 해류도, 그리고 계절과 깊이에 상관없이 황해 및 동중국해를 대표할 수 있는 하나의 표층해류도 등 총 7개로 제작되었다. 이 해류도들은 향후 동해와 북서태평양 해류도와 연결하여 중등학교 교과서 및 고등교육, 나아가서는 과학 전문가를 위한 해류도로서 널리 활용될 것으로 기대된다.

Most of oceanic current maps in the secondary school science and earth science textbooks have been made on the base of extensive in-situ measurements conducted by Japanese oceanographers during 1930s. According to up-to-date scientific knowledge on the currents in the Yellow Sea and the East China Sea (YES), such maps have significant errors and are likely to cause misconceptions to students, thus new schematic map of ocean currents is needed. The currents in the YES change seasonally due to relatively shallow water depths, complex terrain, winds, and tides. These factors make it difficult to construct a unified ocean current map of the YES. Sixteen major items, such as the flow of the Kuroshio Current into the East China Sea and its northward path, the origin of the Tsushima Warm Current and its path into the Korea Strait, the path of Taiwan Warm Current, the Jeju Warm Current, the runoff pattern of the Yangtze River flow, the routes of the northward Yellow Sea Warm Current, the Chinese Coastal Current, and the West Korea Coastal Current off the west coast of the Korean Peninsula, were selected to produce the schematic current map. Review of previous scientific researches, in-depth discussions through academic conferences, expert discussions, and consultations for three years since 2014 enabled us to produce the final ocean current maps for the YES after many revisions. Considering the complexity of the ocean currents, we made seven ocean current maps: two representative current patterns in summer and winter, seasonal current maps for upper layer and lower layer in summer and winter, and one representative surface current map. It is expected that the representative maps of the YES, connected to the current maps of the East Sea and the Northwest Pacific Ocean, would be widely utilized for diverse purposes in the secondary-school textbooks as well as high-level educational purposes and even for scientific scholarly experts.
