Chesapeake Bay Nontidal Network 1985-2016: WRTDS output data

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2016. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on Time, Discharge, and Season). The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the NTN watersheds.切萨皮克湾流域内各河流的氮、磷与悬浮泥沙负荷及其变化量，已基于切萨皮克湾非潮汐网络（Chesapeake Bay Nontidal Network，NTN）站点1985至2016年的监测数据完成计算。其中，营养盐与悬浮泥沙负荷及其变化量，通过采用名为WRTDS（Weighted Regression on Time, Discharge, and Season，时间-流量-季节加权回归）的加权回归方法确定。该负荷计算结果代表各NTN流域输出的氮、磷及悬浮泥沙总质量。
