Sulfur hexafluoride and helium data from a tracer release experiment conducted in July 2022 in the central Baltic Sea during research cruise EMB295 on the R/V Elisabeth Mann Borgese

This dataset contains measurements of helium-3 (3He) and sulfur hexafluoride (SF6) concentrations obtained from a tracer release experiment conducted in the central Baltic Sea aboard research cruise EMB295 on the R/V Elisabeth Mann Borgese from June 30th to July 19th, 2022. SF6 concentrations were measured onboard using a gas chromatograph equipped with an electron capture detector (GC-ECD), following gas separation via a purge-and-trap SF6 analysis system. 3He concentrations were determined at the laboratory at the Institute of Environmental Physics at the University of Bremen, using a helium isotope mass spectrometer (MAP 215-50).
