Abstract

This dataset includes model simulations of the following tracers using the Transport Matrix Method (TMM): (i) 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), and (ii) 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. Together these measurements and model simulations provide insight i...

Note: all methods are described in detail in the accompanying publication currently in final review at Proceedings of the National Academy of Sciences.

All model simulations were carried out using the University of Victoria Earth System Climate Model (UVic ESCM) via the Transport Matrix Method (TMM), using an updated version of the gas exchange model of Nicholson et al. (2016) to include noble gas isotopes, N2, and different gas exchange parameterizations. A full description is included in the accompanying paper (Seltzer et al., 2023).

The BATS data and TTO data are available as related datasets at BCO-DMO. See the following:
