Summary

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 [...]

Purpose

This effort was a pilot study for adapting current technologies and monitoring approaches to measure water quality and stratification across submerged aquatic vegetation beds in the Sacramento-San Joaquin Delta. The pilot study was part of a larger multi-year study to better understand the effects of invasive aquatic vegetation on Delta habitats conducted by the California Department of Water Resources (DWR), in collaboration with California State Parks Division of Boating and Waterways (DBW). The study was completed under the California Natural Resources Agency’s Delta Smelt Resiliency Strategy to study measured water quality constituents in two wetland habitats with similar hydrologic regimes.
