南极乔治王岛燕鸥湖Ａ孔深７．７６ｍ，其中第四纪沉积厚７．３４ｍ，含多门类淡水及海生生物，尤以硅藻植物特别丰富，自下而上可分为９个组合。各个生物群的存在，显示了燕鸥湖经历了冰缘洼地－海陆过渡－海相－湖泊沉积的变化发展过程。孔深５１８－６００ｃｍ的海相生物组合，反映曾发生过海平面上升事件，推测其时代与南极半岛地区８０００－５０００ａＢＰ出现的高海平面时间相当。随之发生的海生生物突然消失，与地壳隆升运动有关。 Antarctic King Island Yan hole A hole 7.76m deep, of which Quaternary sediments 7.34m thick, with a wide range of freshwater and marine life, especially diatom plants are particularly rich, bottom-up can be divided into 9 combination. The existence of each biota shows that Ternopil Lake experienced the process of the change and development of the marginal ice-land-sea transition-marine-lacustrine sediments. The marine assemblage of 518-600 cm deep in the hole reflects the sea level rise that occurred at a time comparable to the high sea level of 8000-5000 a BP in the Antarctic Peninsula. The consequent sudden disappearance of marine life, and the uplift movement of the earth’s crust.
