摘要

由於全球暖化的緣故，致使南極海面上持續形成大小不一的漂流冰山，海冰的存在對海流確實已產生顯著之影響。本研究首度嘗試運用輸送現象為手段，針對此現象來剖析洋流及冰山間之交互關係，以進行分析大型冰山的存在是否確實已對海洋或是冰河流動產生決定性之相關影響，並試圖量化其間之影響機制。相關南極冰山之深入研究勢必對全球暖化成因關係之理解及解決途徑可產生極積極正面之作用。

Due to global warming, the formation of various sized icebergs drifted in the Antarctic Ocean apparently expressed significant effects on characteristics of ocean current. This first-attempt study disclosed the interactive mysteries behind ocean current and icebergs from the perspective of transport phenomena, revealing whether the presence of large sized iceberg enticed significant impacts to ocean current and the water flux of glacier. In addition, this model study quantitatively unveiled the plausible mechanism, reasoning and solutions for characteristics of Antarctic icebergs in response to world-wide global warming.
