论文摘要
1）南部高纬度地区大气甲烷的年周期与南极海冰范围非常高度相关。 2）北极中大气甲烷的年周期与南极或北极加南极海冰范围高度相关。 3）我们提出的是大气甲烷的全球年度周期主要是由南极海冰动力学驱动的，其影响相对较大，其影响相对较大，而北半球的其他通量（可能是Biota）的影响相对较大。 4）我们在海冰冷冻期间提出脱气，并且海洋中的温度依赖性溶解度主导了一年一度的甲烷周期。 5）结果提供了证据表明碳循环途径，参数和预测必须重新评估。
1) The annual cycle of atmospheric methane in southern high latitudes is extremely highly correlated with Antarctic sea ice extent. 2) The annual cycle of atmospheric methane in the Arctic is highly correlated with Antarctic or Arctic plus Antarctic sea ice extent. 3) We propose the global annual cycle of atmospheric methane is largely driven by Antarctic sea ice dynamics, with relatively stronger influence from other fluxes (probably the biota) in the Northern Hemisphere. 4) We propose degassing during sea ice freeze and temperature dependent solubility in the ocean dominate the annual methane cycle. 5) Results provide evidence that carbon cycle pathways, parameters and predictions must be reassessed.
