2000年至2020年的水质参数,以确定空间和时间的硫酸盐变化在墨西哥湾西北部的河口。硫酸盐富集相对于保守的混合被认为是与一个低的河流排放期,从2012年至2014年在所有河口。基于化学计量学,沉积硫化物氧化具有显著的降低河口沃茨碱度的潜力。然而,在这种极端干旱,碱度富集也偶尔观察到在一些南部河口沿着硫酸盐富集,当碱度耗尽发生时,耗尽的幅度通常远小于预期的硫化物氧化。这种差异可以通过碳酸盐溶解和其他质子去除途径(例如,铁氧化物溶解),以及用于估计碱度富集/贫化的模型中的不确定性。在气候变化条件下,河流流量变化与河口硫酸盐动力学之间的密切耦合将对河口碳酸盐化学产生重要影响。
Water quality parameters from 2000 to 2020 were used to identify the spatial and temporal sulfate variations in estuaries of the northwestern Gulf of Mexico. Sulfate enrichment relative to conservative mixing was found to be associated with a low river discharge period from 2012 to 2014 in all estuaries. Based on reaction stoichiometry, sedimentary sulfide oxidation holds significant potential for reducing the alkalinity in estuarine waters. However, during this extreme drought, alkalinity enrichment was also occasionally observed in some of the southern estuaries along with sulfate enrichment, and when alkalinity depletion occurred, the magnitude of depletion was usually much less than what would be expected based on sulfide oxidation alone. This discrepancy can be partially explained by carbonate dissolution and other proton removal pathways (e.g., Fe‐oxide dissolution), and by the uncertainties in the model used to estimate alkalinity enrichment/depletion. Under a changing climate, the close coupling between river discharge variation and estuarine sulfate dynamics will significantly impact estuarine carbonate chemistry.
