【摘要】：利用中國(guó)第五次北極科學(xué)考察CTD資料,分析了2012年夏季包括白令海陸架區(qū)和楚科奇海在內(nèi)的白令海峽附近海域水文特征:1)白令海峽南側(cè)的白令海陸架區(qū)按照不同的水團(tuán)性質(zhì),可以分為圣勞倫斯島以南和圣勞倫斯島以北兩個(gè)區(qū)域。圣勞倫斯島以南海域,東部有阿拉斯加沿岸水流過(guò),水體垂向混合均勻,具有高溫低鹽的分布特征。向西在25m深度附近存在溫躍層,躍層以下溫度分布出現(xiàn)層化現(xiàn)象。西南部陸架區(qū)存在低溫的白令海陸架水,其下方靠近白令海陸坡區(qū)存在高鹽的白令海陸坡流水。圣勞倫斯島以北海域,東部是高溫低鹽的阿拉斯加沿岸水,西部是低溫高鹽的阿納德?tīng)査?)白令海峽北側(cè),入流水對(duì)楚科奇海環(huán)流影響較大,高溫低鹽的阿拉斯加沿岸水仍沿東側(cè)近岸海域向北運(yùn)動(dòng)。西側(cè)是低溫高鹽的阿納德?tīng)査?但至69°00′N(xiāo)附近,該低溫高鹽信號(hào)消失,斷面層化現(xiàn)象逐漸顯著。隨著水團(tuán)繼續(xù)向北運(yùn)動(dòng),溫度逐漸降低,鹽度逐漸升高。
[Abstract]:Using the CTD data of the fifth Arctic Scientific Survey of China, the hydrological characteristics of the Bering Strait near the Bering Strait, including the Bering Sea continental shelf and the Chukchi Sea, were analyzed in the summer of 2012. The Bering Sea continental shelf on the south side of the Bering Strait was characterized by different water mass properties. It can be divided into two areas south of St. Lawrence Island and north of St. Lawrence Island. To the south of St. Lawrence Island, there is Alaska coastal water flowing through the east, the water body is mixed evenly vertically and has the characteristics of high temperature and low salt distribution. The thermocline exists westward near the depth of 25m, and the temperature distribution below the cline is stratified. There is a low temperature Bering sea shelf water in the southwest continental shelf, and a high salt flowing water on the Bering sea slope near the Bering sea continental slope. To the north of St. Lawrence Island, in the east is Alaska coastal water with high temperature and low salt, and in the west is Anadell water with low temperature and high salt. 2) the northern side of the Bering Strait. The inflow of water has a great impact on the circulation of the Chukchi Sea. Alaskan coastal waters with high temperature and low salt still move north along the east coast. On the west side is Anadell water with low temperature and high salt, but up to 69 擄00N, the signal of low temperature and high salt disappears, and the stratification of cross section becomes more and more obvious. As the water mass moves northward, the temperature decreases and the salinity increases.
