Abstract. A historical dataset of river chemistry and discharge is presented for 140 monitoring sites along the United States East Coast, the Gulf of Mexico, and the West Coast from 1950 to 2020. The dataset, referred to here as River Chemistry for the U.S. Coast (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 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. Here we present the method to derive RC4USCoast and briefly describe the river's carbonate chemistry patterns.

RC4USCoast：美国东部、墨西哥湾和西海岸区域海洋模型应用的河流化学数据集

摘要。提供了 1950 年至 2020 年美国东海岸、墨西哥湾和西海岸沿线 140 个监测点的河流化学和流量的历史数据集。该数据集在此称为美国海岸的河流化学 (RC4USCoast )，主要来自美国地质调查局 (USGS) 的水质数据库，但也包括来自 USGS 的全国和美国陆军工程兵团地表水月度统计数据的河流排放量。RC4USCoast 为包括碱度和溶解无机碳浓度在内的 20 个变量提供每月时间序列以及长期平均每月气候模式。它主要用作美国沿海地区的区域海洋生物地球化学模型和碳化学研究的数据产品。
