Water quality, nutrient, and phytoplankton data from Franks Tract, Mildred Island, and neighboring channels in the California Sacramento-San Joaquin Delta: 2022 and 2023 High-resolution mapping surveys

Surface water quality, water isotope, and phytoplankton enumeration data were collected to evaluate the impact of an Emergency Drought Barrier (EDB) in False River in the Sacramento-San Joaquin Delta. Data were collected on six days during 2022 and 2023 (June 7, June 21, July 27, August 9, October 12, November 30, 2022, and February 21, 2023). Sampling occurred in Franks Tract, Mildred Island, the San Joaquin River, and various sloughs and cuts connecting these water bodies. High-resolution boat-based mapping data and discrete water samples were collected and analyzed for: nitrate, nitrite, ammonium, soluble reactive phosphorus (orthophosphate), total dissolved nitrogen, total dissolved phosphorus, total phosphorus,...

Above-water hyperspectral field spectroscopy measurements at Franks Tract in the Sacramento-San Joaquin Delta, California

Hand-held hyperspectral spectroscopy data were collected in 2022 in Franks Tract, a flooded area located in the central Sacramento-San Joaquin Delta of California. The data were collected from a boat and co-located within pixels from the Ocean Land Color Imaging (OLCI) sensor on the Sentinel-3A and 3-B satellites. Data from 16 sites within 7 OLCI pixels were collected on three days: July 14, August 3, and November 3, 2022. Radiance measurements from the water, sky, and a reflectance plaque were collected to enable calculation of water-leaving radiance (Mobley 1999, Ruddick et al. 2019). At the location of each spectroscopy site, discrete water samples were also collected and analyzed for chlorophyll a, dissolved...
