Hydrographic variables were monitored in northwestern Arabian Gulf over the past three decades and the time-series data were statistically analyzed. The results show that while salinity has undergone several shifts, seawater temperature exhibited a steady increasing trend since the 1980s. The observed salinity shows strong correlation with Shatt Al-Arab River discharge indicating primary contribution of freshwater to salinity among other factors (evaporation and desalination effluent). Recent data show that salinity is at its highest level in the last 30years with less pronounced seasonal variability in response to severe decline in the freshwater runoff into the northwestern Arabian Gulf. The changes in hydrographic conditions may have significant implications on hydrodynamics, water quality, and ecosystems in the Gulf. Thus, cooperation among the concerned countries - both coastal and riparian nations - would be essential for prevention of further major changes in the Gulf.
在过去三十年里，对阿拉伯湾西北部的水文变量进行了监测，并对时间序列数据进行了统计分析。结果表明，虽然盐度发生了几次变化，但自20世纪80年代以来，海水温度呈现出稳定上升的趋势。观测到的盐度与阿拉伯河流量密切相关，这表明淡水是影响盐度的主要因素，其他因素（蒸发和海水淡化废水）也有一定作用。最新数据显示，盐度处于过去30年的最高水平，由于流入阿拉伯湾西北部的淡水径流量严重下降，季节性变化不太明显。水文条件的变化可能对海湾的水动力、水质和生态系统产生重大影响。因此，相关国家——包括沿海国家和沿岸国家——之间的合作对于防止海湾发生进一步的重大变化至关重要。
