氚和氦同位素数据提供了海洋环流、通风和混合以及生物地球化学过程和深海热液过程速率的关键信息。我们在此介绍由许多研究人员和实验室在超过60年的时间里测量的全球海洋氚和氦同位素数据集。数据集的DOI是https://doi.org/10.25921/clsn - 9631,和数据可在https://www.nodc.noaa.gov/ocads/data/0176626.xml上交替(最后访问:2019年3月15日)或http://odv.awi.de/data/ocean/jenkins-tritium-helium-data-compilation/(最后访问:2019年3月13日),包括约60 000个有效氚测量,63年000个有效氦同位素决定,57 000溶解氦浓度,34 000氖溶解浓度。采用了一些质量控制，标记了有问题的数据，并完全排除了明显受损的数据。包含了适当的元数据，包括地理位置、日期和样本深度。如果可以，我们会包括水温、盐度和溶解氧。还包括数据质量标志和数据发起者信息（包括方法）。本文介绍了该数据集，并对其更广泛的质量和图形进行了一些讨论。
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/clsn-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.
