nitrate concentration gradients
Detailed Description
Map of study area showing example spatially explicit nitrate data from a ~5-hour mapping campaign from Sac River at Rio Vista, CA, through the study area, returning to Rio Vista Aug, 2015. Variation in nitrate concentration gradients are seen throughout the transect. Lower nitrate concentrations are seen (dark green) in Franks Tract.
