人为盐源导致劳伦特五大湖的盐度上升。在密歇根湖，氯化物浓度从19世纪的约1-2 mg L−1上升到2020年的> 15 mg L−1。密歇根湖大约300条支流的流域大小不等，代表着从未开发的森林流域到城市化和农业地区的广泛土地利用。密歇根湖的支流之间的大小和土地覆盖的空间变异性，有助于氯化物浓度和负载的巨大变化。我们进行了密歇根湖支流的空间评估，以计算每年的总盐负荷，推断未来的条件下，根据目前的模式，评估天气采样的使用，并确定流域特征，驱动高氯化物浓度。我们发现，密歇根湖的支流负荷是1.08 Tg yr−1的氯化物，密歇根湖的氯化物浓度在未来几十年可能会继续缓慢上升。
Anthropogenic salt sources have contributed to rising salinities in the Laurentian Great Lakes. In Lake Michigan, chloride concentrations have risen from ~ 1–2 mg L−1 in the 1800s to > 15 mg L−1 in 2020. The watersheds of the approximately 300 tributaries of Lake Michigan vary in size and represent a wide range of land use, from undeveloped forested watersheds to urbanized and agricultural areas. The spatial variability in both size and land cover among Lake Michigan's tributaries contributes to enormous variation in chloride concentrations and loads. We performed a spatial assessment of Lake Michigan tributaries to calculate total annual salt loading, infer future conditions based on current patterns, evaluate the use of synoptic sampling, and identify watershed characteristics that drive high chloride concentrations. We found that the tributary load to Lake Michigan is 1.08 Tg yr−1 of chloride, and that chloride concentrations in Lake Michigan will likely continue to slowly rise in the coming decades.
