美国大西洋陆架35,000年来的海平面曲线,是建立在80多个放射性碳年代的基础上,其中15个年代是老于15,000年代的。测年的材料包括浅水软体动物、鲕状岩、珊瑚藻、海滩岩和盐沼泥炭。30,000—35,000年前的海平面,曾经是接近于现在的海平面的。随后冰川发育,16,000年前海平面降低到负130米左右。全新世海侵可能开始于约14,000年前,并迅速地延续到约7,000年前。世界大多数大陆架的年代和这条曲线相一致,说明这条曲线大致是这个时期海平面升降的曲线。
The 35,000-year sea-level curve on the continental shelf of the United States is based on more than 80 radiocarbon dating ages, 15 of which are older than the 15,000s. The dating materials include shallow-water molluscs, oolitic rocks, coral algae, beach rocks and salina peat. The sea level 30,000-35,000 years ago was once close to current sea level. Glaciers then developed and the sea level dropped to minus 130 meters 16,000 years ago. Holocene transgressions can begin about 14,000 years ago and quickly reach about 7,000 years ago. The age of most continental shelves in the world is consistent with this curve, indicating that this curve is roughly the sea level rise and fall curve for this period.
