“…This corresponds to stage 3 in the conceptual model (figure 4.1). This event represents a second example of an increased biological response to the passage of an intensifying mode-water eddy and again highlights the potential importance of blooms of larger phytoplankton, stimulated by mesoscale eddies, to the C and N budgets (Goldman, 1988;. Oct 10.14 .…”

“…In the summer of 1986, Jenkins (1988) observed upwelled nutrients by comparing two hydrographic profiles sampled one month apart and documented an eddy-driven nutrient injection event that led to the conclusion that eddies could account for 20-30 % of the annual new production in the Sargasso Sea. Work by Goldman (1988; also suggests that eddies are capable of significantly impacting new production in the Sargasso Sea. His work shows that a very small initial population of diatoms can achieve growth rates in culture experiments that would contribute enough new production in a period of days to weeks to equal the annual new production estimates of Jenkins and Goldman (1985) for the Sargasso Sea.…”

“…His work shows that a very small initial population of diatoms can achieve growth rates in culture experiments that would contribute enough new production in a period of days to weeks to equal the annual new production estimates of Jenkins and Goldman (1985) for the Sargasso Sea. Blooms of this type could result from an eddy driven injection of nutrients and might be missed in the BATS monthly to semi-monthly fixed point sampling scheme due to their short duration but which would significantly alter estimates the C and N budgets (Goldman, 1988;.…”

“…Also, large phytoplankton cells contain many times the carbon content of small cells; for example, ~ 5 x 10 4 cyanobacteria equal the carbon content of one 100 ).lm round diatom (Goldman, 1988). (some up to 2 -4 mm) (some mesoplankton)…”

“…Finally, the July 234Th flux was among the highest measurements in the time series at over 1000 dpm/m2/d. This scenario corresponds to stage 4 of the conceptual model (figure 4.1) and represents an example of a significant diatom bloom resulting from an eddy that the work of Goldman (1988; indicates could represent significant new production.…”

Dissolved cobalt (DCo; <0.2 μm; 14 to 93 pM) and the apparent particulate cobalt (PCo; >0.2 μm; <1 to 15 pM) were determined in the upper water column (<1000 m) of the western Atlantic Ocean along the GEOTRACES-A02 section (64°N to 50°S). The lowest DCo concentrations, typical of a nutrient-type distribution were observed in surface waters of the subtropical domains. Strong linear relationships between DCo and phosphate (P) as well as meridional gradients of decreasing DCo from high latitudes were characterized and both linked to the Co biological requirement. External sources such as the Amazon and the atmospheric deposition were found to contribute significantly (>10%) to the DCo stock of the mixed layer in the equatorial and north subtropical domains. Biotic and abiotic processes as well as the physical terms involved in the biogeochemical cycle of Co were defined and estimated. This allowed establishing the first global budget of DCo for the upper 100 m in the western Atlantic. The biological DCo uptake flux was the dominant sink along the section, as reflected by the overall nutrient-type behavior of DCo. The regeneration varied widely within the different biogeochemical domains, accounting for 10% of the DCo-uptake rate in the subarctic gyre and for up to 85% in southern subtropical domain. These findings demonstrated that the regeneration is likely the prevailing source of DCo in the surface waters of the western Atlantic, except in the subpolar domains where physically driven sources can sustain the DCo biological requirement.
