北方和南方巴塔哥尼亚冰原的体积正在迅速减少,目前的体积损失率超过20 km 3 a−1。然而,其体积损失的空间和时间分布的细节仍然不确定。我们使用四个冰川化的巴塔哥尼亚河流域的水文平衡来评估21世纪冰川体积损失的速率。我们隔离的流量贡献的冰量的变化,并评估体积损失率是否减少,增加,或保持不变。在11个冰川化子流域中,有7个表现出冰量损失率的显著增加,2006-2019年冰川体积损失率的时间综合异常为135 ± 50 km 3。这种冰川体积损失率的异常在空间上是不均匀的,从7.06 ± 1.69 m a−1的冰损失增加到3.18 ± 1.48 m a−1的冰损失减少。在早春和夏末发现冰损失率的最大增加,这表明融化季节的延长。我们的研究结果强调了巴塔哥尼亚湖泊终止冰川的体积损失率正在增加,在某些情况下正在加速,2006-2019年冰川体积损失率的异常导致全球平均海平面上升0.027 ± 0.01 mm a−1。
The Northern and Southern Patagonian Icefields are rapidly losing volume, with current volume loss rates greater than 20 km3 a−1. However, details of the spatial and temporal distribution of their volume loss remain uncertain. We evaluate the rate of 21st-century glacier volume loss using the hydrological balance of four glacierised Patagonian river basins. We isolate the streamflow contribution from changes in ice volume and evaluate whether the rate of volume loss has decreased, increased, or remained constant. Out of 11 glacierised sub-basins, seven exhibit significant increases in the rate of ice volume loss, with a 2006–2019 time integrated anomaly in the rate of glacier volume loss of 135 ± 50 km3. This anomaly in the rate of glacier-volume-loss is spatially heterogeneous, varying from a 7.06 ± 1.69 m a−1 increase in ice loss to a 3.18 ± 1.48 m a−1 decrease in ice loss. Greatest increases in the rate of ice loss are found in the early spring and late summer, suggesting a prolonging of the melt season. Our results highlight increasing, and in some cases accelerating, rates of volume loss of Patagonia's lake-terminating glaciers, with a 2006–2019 anomaly in the rate of glacier volume loss contributing an additional 0.027 ± 0.01 mm a−1 of global mean sea-level rise.
