The distribution of dissolved zinc in the Atlantic sector of the Southern Ocean

A seasonal study of dissolved cobalt in the Ross Sea, Antarctica: micronutrient behavior, absence of scavenging, and relationships with Zn, Cd, and P

“…Saito, personal communication, 2010). Lack of excess strong ligand has also been observed for Cd in Terra Nova Bay of the Ross Sea (Capodaglio et al, 1998) and Zn in the Atlantic sector of the Southern Ocean Croot et al, 2010). This results in higher concentrations of bioavailable Zn in shallow waters and with that a lessened contribution to Cd:PO 3− 4 kink formation by the Zn mechanism.…”

Bioactive Trace Metal Distributions and Biogeochemical Controls in the Southern Ocean

“…These results, however, were never unequivocally confirmed during bottle incubation experiments of ambient Southern Ocean water subjected to enrichments of Zn (Scharek et al, 1997;Coale et al, 2003;Ellwood, 2004) or Mn (Martin et al, 1990a, Buma et al, 1991Scharek et al, 1997;Sedwick et al, 2000). In retrospect, the lack of evidence (Martin et al, 1990b;Coale et al, 2005;Ellwood, 2008;Croot et al, 2011). Dissolved Zn and Si are generally strongly correlated in the Southern Ocean, even though a physiological mechanism connecting Si and Zn uptake in marine diatoms remains elusive (Ellwood, 2008;Croot et al, 2011).…”

Dissolved Zn and Si are generally strongly correlated in the Southern Ocean, even though a physiological mechanism connecting Si and Zn uptake in marine diatoms remains elusive (Ellwood, 2008;Croot et al, 2011). However, given that diatoms are a dominant taxonomic group in the Southern Ocean, they potentially dictate the cycling of Zn in these waters (Ellwood, 2008).…”

Diagnosing oceanic nutrient deficiency

“…Data on the distributions of the macronutrient elements N, P, Si [44,[62][63][64][65][66][67], the micronutrient elements Fe, Mn, Ni, Zn and Cd [64,[68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84] and the non-nutrient element Al [67,85,86] were downloaded from the IDP2014 collection [20] and imported into a Matlab™ environment for analysis. For each sampling location and/or seawater volume/water mass, a ranking of the relative deficiencies of multiple nutrient elements was calculated by dividing observed dissolved concentrations by an assumed 'typical' stoichiometric ratio within newly formed organic (biological) material (figure 1) [11,18].…”
