Long-term Trends in Phosphorus Loads at USGS RIM Stations

Open the Data Resource: https://gis.chesapeakebay.net/server/rest/services/ChesapeakeProgress/cpUSGS_RIM_Long_Term_Trends_2023/MapServer/2 This Chesapeake Bay Program indicator of progress toward the Water Quality Standards Attainment and Monitoring Outcome shows long-term trends (i.e., since 1985) in phosphorus loads at nine RIM stations across the Chesapeake Bay watershed. This data resource is separate from Long-term Trends in Nitrogen Loads and Long-term Trends in Sediment Loads.请访问以下数据源：https://gis.chesapeakebay.net/server/rest/services/ChesapeakeProgress/cpUSGS_RIM_Long_Term_Trends_2023/MapServer/2。该数据集为切萨皮克湾项目（Chesapeake Bay Program）中用于表征水质标准达标与监测成果进展的指标，展示了切萨皮克湾流域（Chesapeake Bay watershed）内9个RIM站点（RIM stations）自1985年起的磷负荷长期变化趋势。本数据集与氮负荷长期趋势数据集、沉积物负荷长期趋势数据集相互独立。
