Delaware River Basin Stream Salinity Machine Learning Model Simulations for Past and Future Drought This model archive contains the input data, model code, and model outputs for machine learning models that predict daily non-tidal stream salinity (specific conductance) for a network of 459 modeled stream segements across the Delaware River Basin (DRB). Results are provided for two time periods: the historical drought-of-record from 1965-10-02 to 1969-12-30, and that same drought evaluated in climatic conditions that are consistent with a LENS2 enseble climate projection from 2057-10-02 to 2061-12-30. Results are provided for a total of three Random Forest models, corresponding to three input attribute sets (dynamic attributes, dynamic and static attributes, and dynamic attributes and a minimum set of static attributes)....

The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in cooperation with the State Water Board, and in partnership with other State and local agencies. The USGS collected and analyzed groundwater, surface water, and associated quality control (QC) samples in the Elk Hills study area during June 2017–April 2018.

The site code (NWFN or North West Field North) reflects a location on Andersen Air Force Base, Northern Guam, which has been a study site for close to two decades. The experimental process followed an adaptive resource management process to develop an integrated pest management strategy for either eradication or validating whether extant species (rodents, lizards, and birds) would respond to population suppression over a 6 year removal effort.

This dataset includes the chemical concentrations of the sediment samples collected in sediment traps during storm events. These traps collected sediment during storm events that typically occur as monsoonal convective storms from June to September. Because of the rural nature of the watershed, sediment traps were collected every 3 weeks so the sediment collected is a composite of that time period. The date listed is the date the trap was collected. Major ions are reported in weight percentage, while all other elements are reported in parts per million.

The 44-foot-long core was collected on 05/16/2023 using the North Carolina Geological Survey Geoprobe. The core was collected from sands and gravels of the uppermost coastal plain that host the Old Hickory heavy mineral deposit. Because host sediments are non-fossiliferous, there is little consensus as to their age, stratigraphic position, or nomenclature. Current mapping assigns host sands and gravels to two units in the upper part of the Pliocene to Pleistocene Chesapeake Group. In the lab, the core was analyzed...
