海冰表面被认为是海盐气溶胶的主要来源,这表明极地冰芯的钠记录可以追溯过去的海冰范围。在这里,我们测试这种可能性的北极,使用化学传输模型来模拟气溶胶的排放,运输和沉积在卫星时代。我们的模拟表明,钠记录从内陆格陵兰冰芯的气溶胶输送和沉积的气象影响的强烈影响。相比之下,在沿海北极核心钠主要来自海冰表面和这些气溶胶排放的强度控制冰芯钠的变化。因此,这些冰芯可能记录了十年至百年尺度的全新世海冰变化。然而,冰芯钠和海冰变化之间的任何关系可能取决于海冰季节性如何影响海盐排放。迫切需要实地观察来限制这一点。
The sea ice surface is thought to be a major source of sea salt aerosol, suggesting that sodium records of polar ice cores may trace past sea ice extent. Here we test this possibility for the Arctic, using a chemical transport model to simulate aerosol emission, transport, and deposition in the satellite era. Our simulations suggest that sodium records from inland Greenland ice cores are strongly influenced by the impact of meteorology on aerosol transport and deposition. In contrast, sodium in coastal Arctic cores is predominantly sourced from the sea ice surface and the strength of these aerosol emissions controls the ice core sodium variability. Such ice cores may therefore record decadal to centennial scale Holocene sea ice changes. However, any relationship between ice core sodium and sea ice change may depend on how sea ice seasonality impacts sea salt emissions. Field‐based observations are urgently required to constrain this.
