Correction to “Coupled nitrogen and oxygen isotope measurements of nitrate along the eastern North Pacific margin”

[1] In the paper ‘‘Coupled nitrogen and oxygen isotope measurements of nitrate along the eastern North Pacific margin’’ (Global Biogeochemical Cycles, 19, GB4022, doi:10.1029/2005GB002458, 2005), the fourth author name was erroneously listed as Moritz M. Lehmann rather than the correct Moritz F. Lehmann. [2] In paragraph [6], in the third sentence the values k/k should be reversed, so that the parenthetical phrase reads as follows: ‘‘(the N isotope effect, e, is defined here as (k/k 1) 1000%, where k and k are the rate coefficients of the reactions for the Nand N-bearing forms of NO3 , respectively).’’ [3] In paragraph [11], in the first sentence the redundant phrase ‘‘the ambient water’’ should be removed so that the sentence reads as follows: ‘‘Measurements to date from the ocean indicate that away from regions of known denitrification, subsurface NO3 dO varies relatively little and is close to the ambient water (0 ± 1% or 3 ± 1% different from it; see auxiliary material, endnote i in Auxmat1.txt) (dOsample = ((O/O)sample/( O/O)reference 1) 1000%, where the reference is Vienna Standard Mean Ocean Water (VSMOW); see section 2).’’ [4] In paragraph [18], in the fourth sentence the value 5% should be changed to 3% so that the sentence reads as follows: ‘‘The O isotope data are corrected for exchange with oxygen atoms from water during reduction of NO3 to N2O [Casciotti et al., 2002], which is quantified by analysis of IAEA-N3 in O-enriched water and was 3% or less for the analyses reported here.’’ [5] The above errors and additional ones were left uncorrected owing to editorial oversight. The authors have decided to allow several additional typographical errors to stand, to shorten the published correction. GLOBAL BIOGEOCHEMICAL CYCLES, VOL. 20, GB1005, doi:10.1029/2005GB002682, 2006
