RC4USCoast: A river chemistry dataset for regional ocean model application in the U.S. East, Gulf of Mexico, and West Coasts from 1950-01-01 to 2022-12-31 (NCEI Accession 0260455)

This dataset, River Chemistry for the U.S. Coast (RC4USCoast), consists of historical records of river chemistry and discharge for 140 monitoring sites along the United States East Coast, the Gulf of Mexico, and the West Coast from 1950 to 2022. RC4USCoast is mostly derived from the Water Quality Database of the U.S. Geological Survey (USGS), but also includes river discharge from the USGS’s Surface-Water Monthly Statistics for the Nation and the U.S. Army Corps of Engineers. RC4USCoast provides monthly time series as well as long-term averaged monthly climatological patterns for twenty-one variables including alkalinity and dissolved inorganic carbon concentration. It is mainly intended as a data product for regional ocean biogeochemical models and carbon chemistry studies in the U.S. coastal regions.
