Coupled response of the late glacial climatic shifts of northwest Europe reflected in Greenland ice cores: Evidence from the northern North Sea

The climatic regimes of the land areas adjacent to the North Sea are controlled by the influx of Atlantic water north of the British Isles and into the North Sea. A high-resolution record from the Norwegian Channel off western Norway covering the past 15 ka ( 14 C) shows that prior to the Younger Dryas, there were three periods of sea-surface conditions there similar to those of the present, interspersed with arctic conditions. These changes, corresponding to an increase of (Approx.)5 °C in summer sea-surface temperatures, took place on the scale of
