Oxygen-18 analyses of pelagic and benthic foraminifera from core K 11 indicate that during the last glaciation Norwegian Sea bottom waters were warmer than in modern times and had the same physical parameters (temperature, oxygen isotope ratio, and salinity) as the North Atlantic deep water. This result indicates that the glacial Norwegian Sea was not a sink for dense surface water, as it is now, and that during glacial times North Atlantic deep water invaded the deep Norwegian basin.
来自 K11 岩芯的浮游有孔虫和底栖有孔虫的氧-18 分析表明，在上一个冰期，挪威海底层水比现代时期温暖，并且具有与北大西洋深水相同的物理参数（温度、氧同位素比值和盐度）。这一结果表明，与现在不同，冰期的挪威海不是高密度表层水的汇，而且北大西洋深水在冰期侵入了挪威海深盆地。
