ArticleHogue, Victoria E,We describe the results of a series of 96-h enclosure experiments conducted using water from stations in the northern San Francisco Estuary (SFE) along a gradient in ammonium (NH4) and nitrate (NO3) concentrations. Using dual-labeled 13C/15N tracers, . . .

ArticleWilkerson, Frances P.Increased discharge of ammonium (NH4) to the San Francisco Estuary (SFE), largely in treated domestic sewage effluent, has been linked to chronically food-limited conditions and to reduced fish abundance. Elevated chlorophyll concentrations at phytopl . . .

ArticleRossignol, Pascale E.Coccolithophores are unicellular phytoplankton that produce calcium carbonate coccoliths as an exoskeleton. Emiliania huxleyi, the most abundant coccolithophore in the world’s ocean, plays a major role in the global carbon cycle by regulating the exch . . .

ArticleKimmerer, Wim J.We measured primary production during spring and summer 2006–2007 to determine the carbon supply to the low-salinity pelagic food web of the San Francisco Estuary (SFE). Weekly or biweekly samples were taken at three stations of fixed salinity for siz . . .

ArticleParker, Alexander E.Depth-integrated primary production (ΣP, in grams of carbon per square meter per day) was measured using 14C in the northern San Francisco Estuary (SFE) fromMarch through August of 2006 and 2007. Determinations of ΣP were then used to calibrate a publ . . .

ArticleTaberski, KarenNutrient loadings to urbanized estuaries have increased over the past decades in response to population growth and upgrading to secondary sewage treatment. Evidence from the San Francisco Estuary (SFE) indicates that increased ammonium (NH4) loads hav . . .

ArticleParker, Alexander E.Primary production in the Northern San Francisco Estuary (SFE) has been declining despite heavy loading of anthropogenic nutrients. The inorganic nitrogen (N) loading comes primarily from municipal wastewater treatment plant (WTP) discharge as ammoniu . . .
