High-Resolution Measurements to Identify Effects of Aquatic Vegetation on Water Quality and Stratification

The dataset documents the spatial and temporal variability of nutrients and related water quality parameters at high spatial resolution in the North Delta of the Sacramento-San Joaquin River Delta of California, USA. The dataset includes surface mapping, depth profile, and discrete data for nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen, and chlorophyll as well as information about phytoplankton community composition. Data-collection cruises were conducted over two time periods in July and October 2018 across two flooded islands with dense submerged aquatic vegetation beds. Little Hastings Tract received an herbicide treatment by the California Department of Boating and Waterways and French Island was the untreated control site.
