Summary

This data release documents the spatial and temporal variability of nutrients and related water quality parameters at high spatial resolution in the North Delta in the Sacramento-San Joaquin River Delta of California, USA. The data set includes nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen, turbidity, and chlorophyll . Data-collection cruises were conducted under three different environmental/flow conditions in August, September, and October 2018 that coincided with conditions prior to, during, and following a directed flow action or pulse of agricultural return water organized by the California Department of Water Resources and California Natural Resources Agency .

Purpose

The objective of this project is to document the variability of nutrients and related water quality parameters at high spatial resolution in the North Delta (California, USA). This data release reports measurements that include nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen, turbidity, and chlorophyll.
