Figure 2: Regeneration incubation data.
Data for dissolved Cr concentrations (panel A), stable isotope
composition (panel B) and redox speciation (panel D) are presented for
regeneration incubation 3, along with macronutrients
(PO4: panel E; Si(OH)4: panel F;
NH4: panel H; NO2: panel I) and pMn
(panel G). Incubation sample δ53Cr and [Cr] are
shown over the global array of oceanic data with a trendline fit to all
the data (Panel C), demonstrating the alignment of released Cr along the
global distribution. The ambient temperature (4° C) treatment is shown
as grey circles and the 1° C treatment as white circles, with the
initial dissolved water shown as a black circle.
