如果河口盐度场特征的长期趋势导致路易斯安那州沿海的土地流失，那么这些趋势存在的证据可能存在于历史盐度记录中。对各种盐度统计数据的时间序列中存在的趋势进行了非参数检验。结果似乎强烈影响的气候变化的年代际尺度。在许多监测站发现了统计上显著的趋势。增加和减少的趋势都没有明显的基本空间模式。在现有记录所涵盖的时间内观察到的变化通常太小，不会对占主导地位的沼泽植物造成致命影响。
If long-term trends in the character of the estuarine salinity field are contributing to land-loss in coastal Louisiana, then evidence of the presence of these trends may exist in historical salinity records. Nonparametric tests for the presence of a trend in the time series of various salinity statistics were performed. The results appear to be strongly influenced by climatological variations of decadal scale. Statistically significant trends were found at many stations. Both increasing and decreasing trends occurred with no apparent underlying spatial pattern. The observed changes during the time covered by the available records were generally too small to be lethal to the dominant marsh plants.
