©2020 Biological and Chemical Oceanography Data Management Office.This dataset includes new observations of heavy noble gas ratios (elemental and isotopic ratios) from the Bermuda Atlantic Time-series (BATS) on cruise 10391 on R/V Atlantic Explorer (AE2208) from 30 April 2022 - 05 May 2022. These data were used, along with measurements of Kr/Ar and N2/Ar ratios in stored dissolved gas samples from the Transient Tracers in the Ocean (TTO) program, to model simulations of these tracers using the Transport Matrix Method (TMM). Together these new measurements a...

Samples were collected in the field at the Bermuda Atlantic Time-series (BATS) on cruise 10391 on R/V Atlantic Explorer (AE2208) from 30 April 2022 - 05 May 2022. Samples were collected at the BATS site located at 31°50'N, 64°10'W. Samples were collected in evacuated 6-liter (L) stainless steel canisters by subsampling from 12-L Niskin bottles, filling each to ~3.5 L.
Noble gas isotopes and elemental ratios were measured in the Seltzer Lab at Woods Hole Oceanographic Institution following the methods described in Seltzer and Bekaert (2022). In the lab, samples were equilibrated on a shaking table at constant temperature before being drained, leaving a headspace that was chemically gettered to remove all reactive gases. The purified sample was analyzed on a dual-inlet mass spectrometer in the Seltzer Lab for stable Argon, Krypton, and Xenon (Ar, Kr, and Xe) isotope ratios as well as Kr/Ar and Xe/Ar ratios. All samples (n=27) were analyzed between 13 May and 10 June 2022 and air standards were analyzed weekly throughout this period.
