Data sets

Recent changes in deep ventilation of the Mediterranean Sea; evidence from long-term transient tracer observations (https://www.nodc.noaa.gov/ocads/oceans/Coastal/Meteor_Med_Sea.html) P. Li and T. Tanhua https://doi.org/10.3389/fmars.2020.00594

Short summary

Observations of transient tracer distribution provide essential information on ocean ventilation. The use of several commonly used transient traces is limited as their atmospheric mole fractions do not monotonically change. Here we explore new potential oceanic transient tracers with an analytical system that simultaneously measures a large range of compounds. Combined with the known atmospheric history and seawater solubility, we discuss the utility of selected HCFCs, HFCs, and PFCs as tracers.
