Henneguya sp. in yellowfin goby Acanthogobius flavimanus from the San Francisco Estuary. [PDF]

open access: yesSpringerplus, 2013
Myxozoan spores were observed in yellowfin goby Acanthogobius flavimanus collected from Suisun Marsh, San Francisco Estuary (SFE). Although histopathological changes associated with the parasite were not observed, the spores formed plasmodia that ...

Monitoring Turbidity in San Francisco Estuary and Sacramento-San Joaquin Delta Using Satellite Remote Sensing. [PDF]

open access: yesJ Am Water Resour Assoc, 2021
AbstractThis study utilizes satellite data to investigate water quality conditions in the San Francisco Estuary and its upstream delta, the Sacramento–San Joaquin River Delta. To do this, this study derives turbidity from the European Space Agency satellite Sentinel‐2 acquired from September 2015 to June 2019 and conducts a rigorous validation with in ...

Four decades of water quality change in the upper San Francisco Estuary. [PDF]

open access: yesEstuar Coast Shelf Sci, 2018
Quantitative descriptions of chemical, physical, and biological characteristics of estuaries are critical for developing an ecological understanding of drivers of change. Historical trends and relationships between key species of dissolved inorganic nitrogen (ammonium, nitrate/nitrite, total) from the Delta region of the San Francisco Estuary were ...

Living Fossils: Sturgeon of the San Francisco Estuary [PDF]

open access: yesFrontiers for Young Minds, 2021
Sturgeon are fish that are considered living fossils. Their ancestors date back over 200 million years, to the same time as dinosaurs. These fish can grow taller than humans (over 2 m), weigh over 160 kg, and live as long as humans. Sturgeon species have special adaptations, such as a vacuum-like mouth and body armor called scutes. There are 27 species
