©2020 Biological and Chemical Oceanography Data Management Office.This dataset includes measurements of Kr/Ar and N2/Ar ratios in stored dissolved gas samples collected in 1981 through the Transient Tracers in the Ocean (TTO) program. These data were used, along with new observations of heavy noble gas ratios (elemental and isotopic ratios) from the Bermuda Atlantic Time-series (BATS) on cruise 10391 (30 April 2022 - 05 May 2022), to model simulations of these tracers using the Transport Matrix Method (TMM). Together these new measurements and model simulat...

Samples were collected via the Transient Tracers in the Ocean (TTO) North Atlantic Survey (NAS) in 1981 via shipboard degassing of ~285-liter Gerard Barrel samples. The extraction technique is described in detail in Smethie and Mathiue (1986). Aliquots of archived gas from these samples were analyzed in the Seltzer and Jenkins Labs at Woods Hole Oceanographic Institution for noble gas elemental ratios and O2/Ar and N2/Ar ratios following techniques described in Seltzer et al. (2023).
The model simulations are available as a related dataset at BCO-DMO. See: https://www.bco-dmo.org/dataset/890293
