“…The loss of these elements from particles in the upper oceans has been demonstrated for suspended material (Bishop et al, 1980) and settling material collected in sediment traps . Evidence from the rates of total primary production in the euphotic zone (Eppley and Peterson, 1979;King and Devol,1979) and from the relationship of the chemical composition of phytoplankton to their growth rates and nutritional states (Goldman et al, 1979) indicates that N and P are rapidly recycled within the euphotic zone.…”

“…Microalgal standing stocks in the central gyres are generally considered to be limited by nutrient supply. However, a precise solution to the question of whether phytoplankton growth rate is nutrient limited or not in the main subtropical gyres of the ocean remains elusive after several decades of debate (Eppley et al, 1973;Goldman et al, 1979;Platt and Harrison, 1985;Laws et al, 1987;Falkowski et al, 1992;Banse, 1995).…”

The latitudinal distributions of phytoplankton biomass, composition and production in the Atlantic Ocean were determined along a 10,000-km transect from 503N to 503S in October 1995, May 1996 and October 1996. Highest levels of euphotic layer-integrated chlorophyll a (Chl a) concentration (75}125 mg Chl m\ ) were found in North Atlantic temperate waters and in the upwelling region o! NW Africa, whereas typical Chl a concentrations in oligotrophic waters ranged from 20 to 40 mg Chl m\ . The estimated concentration of surface phytoplankton carbon (C) biomass was 5}15 mg C m\ in the oligotrophic regions and increased over 40 mg C m\ in richer areas. The deep chlorophyll maximum did not seem to constitute a biomass or productivity maximum, but resulted mainly from an increase in the Chl a to C ratio and represented a relatively small contribution to total integrated productivity. Primary production rates varied from 50 mg C m\ d\ at the central gyres to 500}1000 mg C m\ d\ in upwelling and higher latitude regions, where faster growth rates ( ) of phytoplankton ( '0.5 d\ ) were also measured. In oligotrophic waters, microalgal growth was consistently slow [surface averaged 0.21$0.02 d\ (mean$SE)], representing (20% of maximum expected growth. These results argue against the view that the subtropical gyres are characterized by high phytoplankton turnover rates. The latitudinal variations in were inversely correlated to the changes in the depth of the nitracline and positively correlated to those of the integrated nitrate concentration, supporting the case for the role of nutrients in controlling the large-scale distribution of phytoplankton growth rates.

The observed spatial and temporal variability in the biomass speci"c rate of photosynthesis is at least three times larger than currently assumed in most satellite-based models of global productivity.

“…Some investigators argue that nutrients determine standing algal biomass but growth rates are at or near maximum at all times (Goldman et al 1979;Harris 1986). Others suggest that nutrient limitation is frequently interrupted or has many shifts in the identity of the limiting element, as in the "contemporaneous disequilibrium" hypothesis (Richerson et al 1970).…”

Seasonal and spatial patterns in macro- and micronutrient limitation in Joe Pool Lake, Texas

The roles of nitrogen, phosphorus, silicon, and trace nutrients in limiting algal growth were studied over a I-yr period in three sites of a recently impounded, warm monomictic reservoir in north-central Texas using factorial dilution assay experiments. When lake temperature was > 15"C, nutrients limited realized growth rates to half or less of potential growth. Nutrient limitation was obliterated in the fall by floods. Density stratification was not a prerequisite to nutrient limitation in spring. Both macro-and micronutrients were important in terms of frequency of experiments showing limitation and in terms of quantitative degree of limitation. Horizontal variability in the degree of limitation was absent; however, shallower sites showed more incidence of multiple nutrient limitation compared to a deep, near-dam site.
