The data set is comprised of concentrations of dissolved iron (dFe), total-dissolvable iron (TDFe = dissolved iron + acid-labile particulate iron) and dissolved macronutrients (nitate+nitrite, phosphate, silicate) in surface-water and water-column samples collected in the southern Ross Sea during cruises NBP06-01 and NBP06-08 of the RVIB Nathaniel B. Palmer for the NSF-funded CORSACS (Controls on Ross Sea Algal Community Structure) program.
Method used to determine dissolved (<0.2 µm) iron achieved following results for SAFe reference material (filtered seawater): SAFe surface seawater S1: dFe = 0.11 ± 0.01 nM (n = 15) vs consensus value of 0.097 ± 0.043 nM SAFe deep seawater D2: dFe = 0.97 ± 0.06 nM (n = 14) vs consensus value of 0.91 ± 0.17 nM.
