Patterns of Diel Variation in Nitrate Concentrations in the Potomac River

Metadata Updated: October 29, 2023

This data set includes nitrate concentration, water temperature, and discharge collected every 15 minutes during Dec. 2011 - Nov. 2013 from the USGS gage at the Potomac River near Wash, DC, Little Falls Pump Sta (01646500). Additional data includes day length from the US Naval Observatory, and photosynthetically active radiation from USDA research station in Beltsville, MD. Data on channel width and velocity based on manual discharge measurements made at the USGS gage at the Potomac River at Point of Rocks, MD (01638500) are included and were applied to calculate diel nitrate loss rates. Several calculations derived from these data are included in the data set. These data accompany a paper titled "Patterns of Diel Variation in Nitrate Concentrations in the Potomac River", and details about further calculations and summaries based on these data are described in the manuscript.
