3He/SF6 dual‐gas tracer injections were conducted in the southern Baltic Sea between June 06, 2018, and June 11, 2015 aboard the research vessel Alkor (AL510). SF6 was surveyed using a new, fully automated, high-resolution SF6 underway sampling and analysis system described in detail by Ho et al. (2002). For helium isotopes analysis, a total of 145 seawater samples were collected from 23 hydrographic stations aboard the Alkor (AL510), with each sample being secured in 40 ml copper tubes sealed by stainless steel pinch-off clamps. He isotope measurements were conducted in the Noble Gas Laboratory of the Lamont-Doherty Earth Observatory on a dedicated, fully automated VG5400 mass spectrometer following the procedures described by Ludin et al. (1998). Shipboard sampling was done by Tobias (Toby) Koffman. Helium extraction work and isotopic analysis by T. Koffman; data processing by P. Schlosser.
