Mathematical formulation of the relationship between photosynthesis and light for phytoplankton
Eight different mathematical formulations of the photosynthesis—light curve for phytoplankton were recast in terms of the same two parameters: the initial slope α, and the assimilation number PmB.
Isohaline Position as a Habitat Indicator for Estuarine Populations
Populations of native and introduced aquatic organisms in the San Francisco Bay/Sacramento- San Joaquin Delta Estuary have undergone significant declines over the past two decades, and uncertainty analysis can identify the most practical direction for future data acquisition.
Annual primary production: Patterns and mechanisms of change in a nutrient‐rich tidal ecosystem
Although nutrient supply often underlies long‐term changes in aquatic primary production, other regulatory processes can be important. The Sacramento‐San Joaquin River Delta, a complex of tidal…
THE RELATIONSHIP BETWEEN PHOTOSYNTHESIS AND LIGHT FOR NATURAL ASSEMBLAGES OF COASTAL MARINE PHYTOPLANKTON 1
It is deduced that on the average the phytoplankton were photosynthesizing at only 44% maximum capacity, and the results show that PmB could be estimated from α and temperature using an empirical multiple regression equation, independent of depth.
Phytoplankton in the Upper San Francisco Estuary: Recent Biomass Trends, Their Causes, and Their Trophic Significance
- A. Jassby

Several pelagic fish populations in the upper San Francisco Estuary have recently declined to historically low abundances, prompting an interest in the status of their food supply. Previous studies…
Projected Evolution of California's San Francisco Bay-Delta-River System in a Century of Climate Change
A series of models are linked to investigate responses of California's San Francisco Estuary-Watershed system to two contrasting scenarios of climate change, and nine indicators of changing climate, hydrology and habitat quality are presented.
Drivers of change in estuarine‐coastal ecosystems: Discoveries from four decades of study in San Francisco Bay
Poised at the interface of rivers, ocean, atmosphere and dense human settlement, estuaries are driven by a large array of natural and anthropogenic forces. San Francisco Bay exemplifies the…
Atmospheric deposition of nitrogen and phosphorus in the annual nutrient load of Lake Tahoe (California‐Nevada)
Atmospheric deposition provides most of the dissolved inorganic nitrogen (DIN) and total nitrogen in the annual nutrient load of Lake Tahoe. Deposition also contributes significant amounts of soluble…
Patterns and Scales of Phytoplankton Variability in Estuarine–Coastal Ecosystems
Phytoplankton variability is a primary driver of chemical and biological dynamics in the coastal zone because it directly affects water quality, biogeochemical cycling of reactive elements, and food…
Organic carbon sources and sinks in San Francisco Bay: variability induced by river flow
Interannual variability of the total organic carbon supply could not be assessed for the southern reach, and year-to-year changes in phytoplankton production were much smaller than in Suisun Bay, reflecting a relative lack of river influence.
