Use case development for earth monitoring, analysis, and prediction (EarthMAP)—A road map for future integrated predictive science at the U.S. Geological Survey

Executive SummaryThe U.S. Geological Survey (USGS) 21st-century science strategy 2020–30 promotes a bureau-wide strategy to develop and deliver an integrated, predictive science capability that works at the scales and timelines needed to inform societally relevant resource management and protection and public safety and environmental health decisions (U.S. Geological Survey, 2021). This is the ove

Climate and land change impacts on future managed wetland habitat: A case study from California’s Central Valley

ConceptCalifornia’s Central Valley provides critical habitat for migratory waterbirds, yet only 10% of naturally occurring wetlands remain. Competition for limited water supplies and climate change will impact the long-term viability of these intensively managed habitats.ObjectivesForecast the distribution, abundance, and connectivity of surface water and managed wetland habitats, using 5 spatiall

Concentrations, loads, and associated trends of nutrients entering the Sacramento-San Joaquin Delta, California

Statistical modeling of water-quality data collected at the Sacramento River at Freeport and San Joaquin River near Vernalis, California, USA, was used to examine trends in concentrations and loads of various forms of dissolved and particulate nitrogen and phosphorus that entered the Sacramento–San Joaquin River Delta (Delta) from upstream sources between 1970 and 2019. Ammonium concentrations and

The USGS Monitoring Network and the Continuous Collection of Water Quality Data in the Sacramento-San Joaquin Delta

Water quality in Northern California’s Sacramento-San Joaquin Delta (Delta) is essential to clean drinking water, agricultural activities, and the health of the aquatic food web. Management of this important water resource requires the strategic collection of relevant and timely data. A primary component of this data collection is measuring and monitoring water quality.
