Abstract European paleoenvironmental records through the Last Glacial-Interglacial Transition (LGIT; ca 16-8 cal ka BP) record a series of climatic events occurring over decadal to multi-centennial timescales. Changes in components of the climatic system other than temperature (e.g. hydrology) through the LGIT are relatively poorly understood however, and further records of hydroclimatic changes are required in order to develop a more complete understanding on the phasing of environmental and anthropogenic responses in Europe to abrupt climate change. Here, we present a multiproxy palaeoenvironmental record (macroscale and microscale sedimentology, macrofossils, and carbonate stable isotopes) from a palaeolake sequence in the Vale of Pickering (VoP), NE England, which enables the reconstruction of hydroclimatic changes constrained by a radiocarbon-based chronology. Relative lake-level changes in the VoP occurred in close association (although not necessarily in phase) to threshold shifts across abrupt climate change transitions, most notably lowering during cooling intervals of the LGIT (∼GI-1d, ∼GI-1b, and ∼GS-1). This reflects more arid hydroclimates associated with these cooling episodes in the British Isles. Comparisons to hydrological records elsewhere in Europe show a latitudinal bifurcation, with Northern Europe (50–60°N) becoming more arid (humid), and Southern Europe (40–50°N) becoming more humid (arid) in response to these cooling (warming) intervals. We attribute these bifurcating signals to the relative positions of the Atlantic storm tracks, sea-ice margin, and North Atlantic Polar Front (NAPF) during the climatic events of the LGIT.

不列颠群岛通过末次冰期-间冰期过渡的水文气候变化：来自英格兰东北部皮克林谷的多代理重建

摘要 通过末次冰期-间冰期过渡 (LGIT; ca 16-8 cal ka BP) 的欧洲古环境记录记录了一系列发生在十年到百年时间尺度上的气候事件。然而，通过 LGIT 对除温度以外的气候系统组成部分的变化（例如水文）的了解相对较少，需要进一步记录水文气候变化，以便更全面地了解欧洲环境和人为响应的分阶段气候突变。在这里，我们展示了来自英格兰东北部皮克林谷 (VoP) 的古湖序列的多代理古环境记录（宏观和微观沉积学、宏观化石和碳酸盐稳定同位素），这使得重建受基于放射性碳的年表限制的水文气候变化成为可能。VoP 中湖泊水位的相对变化与气候突变过渡期间的阈值变化密切相关（尽管不一定同相），最显着的是在 LGIT 的冷却间隔期间降低（~GI-1d、~GI-1b 和~ GS-1）。这反映了与不列颠群岛的这些降温事件相关的更干旱的水文气候。与欧洲其他地方的水文记录的比较显示了纬度分叉，北欧（50-60°N）变得更加干旱（潮湿），而南欧（40-50°N）变得更加潮湿（干旱）以应对这些冷却（升温）间隔。我们将这些分叉信号归因于大西洋风暴轨迹的相对位置、海冰边缘、
