Abstract
The vertical distribution and chemical characteristics of water masses were measured along two south-north transects in the polar front region of the central Korean East Sea. In February, a thermocline was present at depth between 50m and loom at the southern sites of a landward A-transect, and its depth was gradually deepened northward. At an outside B-transect, a thermocline was observed at significantly deep depth of 300m to 400m at two northern stations(Stn. 10 and 11), though the depth of the southward stations was nearly identical to that at the northward stations on a A-transect. In September, there were vertically more various water masses, i.e. the Tsushima Warm surface water(TWSW) or more than
동해 중부 극전선역에 있어서 동계와 하계에 각종 수괴의 수직분포특성과 이 수괴들의 화학적성 질에 대해 연구하였다. 동계의 경우, 수온약층은 북쪽 바깥 정점들이 남쪽 연안 정점들에 비해 더 깊은 수층에 존재하고, 이 약층의 상부에는 대마난류수가, 하부수층에는 동해고유수가 분포하고 있다. 그러나, 하계에는 수직적으로 대마난류 표층수, 중층수, 북한한류수 및 동해고유수가 분포하고, 동해고유수는 동계보다 다소 상부수층에 존재한다. 하계에 T-S diagram으로는 북한한류수 계통의 수괴, 대마난류 중층수 및 동해고유수의 혼합수를 구분할 수 없었으나,
