• 中文摘要： 1981年冬天作者參加了威得海冰中湖(polynya）探勘研究，工作人員利用蘇聯破冰船蘇莫號(Somov）首度取得了電導、溫度、壓力(CTD)、鹽度、溶氧、營養鹽、pH、鈣、總鹼度、總二氧化碳及二氧化碳分壓之冬季資料，。這些數據代表了在全球海洋底層水形成區於形成時之原始濃度。利用所取得冬季資料與文獻中已有之夏季資料相比得知：極區鋒面(Polar Front）兩側之化學性質差異頗大；威得海表水之二氧化碳分壓僅較大氣中之分壓稍低；水團之混合主導化學性質，如pH，溶氧，總二氧化碳及二氧化碳分壓之分佈，而上述數據有助於研判威得海中水團之來源；鈣及總鹼度資料無法用於分辨水團；深水並非完全混合均勻，而顯現若干不連續面；湧昇至表層之威得海深層水占表層水成份之三分之一。
• 英文摘要： Concurrent CTD, salinity, (方程式無法摘錄) ,nutrients, pH, calcium, total alkalinity, total (方程式無法摘錄) and (方程式無法摘錄) wereobtained in the Weddell Sea in the late austral winter of 1981 as part of the Weddell Polynya Expenditionaboard the Soviet icebreaker SOMOV. These data represent the initial concentrations of chemicals in themost important source region of world ocean bottom waters at the time they were formed. These winterWeddell Sea data were analyzed along with summer data reported in the literature, and the results indicatethat: large variations in chemical concentrations occur across the Polar Front; (方程式無法摘錄) in the Weddell Seasurface water is only slightly lower than the atmospheric value：mixing dominates the distribution of chemi-cal properties; pH, (方程式無法摘錄) , total (方程式無法摘錄) and (方程式無法摘錄) are useful in identifying the sources of waters in the WeddellSea, whereas calcium and alkalinity are not; deep waters are not homogeneous but show discontinuities;the upwelled Weddell Sea Deep Water makes up approximately 1∕3 of the surface layer.
