Abstract:
Abstract. Tritium and helium isotope data provide key information on ocean
circulation, ventilation, and mixing, as well as the rates of biogeochemical
processes and deep-ocean hydrothermal processes. We present here global
oceanic datasets of tritium and helium isotope measurements made by numerous
researchers and laboratories over a period exceeding 60 years. The dataset's
DOI is https://doi.org/10.25921/c1sn-9631, and the data are available at
https://www.nodc.noaa.gov/ocads/data/0176626.xml (last access: 15 March
2019) or alternately
http://odv.awi.de/data/ocean/jenkins-tritium-helium-data-compilation/
(last access: 13 March 2019) and includes approximately 60 000 valid tritium
measurements, 63 000 valid helium isotope determinations, 57 000 dissolved
helium concentrations, and 34 000 dissolved neon concentrations. Some
quality control has been applied in that questionable data have been flagged
and clearly compromised data excluded entirely. Appropriate metadata have
been included, including geographic location, date, and sample depth. When
available, we include water temperature, salinity, and dissolved oxygen. Data
quality flags and data originator information (including methodology) are
also included. This paper provides an introduction to the dataset along with
some discussion of its broader qualities and graphics.
