Helium isotopes and neon 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). Helium and neon samples were collected from Niskin bottles in copper tubes (40 ml) sealed by stainless steel pinch-off clamps. Shipboard sampling, gas extraction, and isotopic analysis were done by Tobias (Toby) Koffman with data processing by Peter Schlosser.\n\ncdm_data_type = Other\nVARIABLES:\nSt_ID (unitless)\nSa_ID_LDEO (unitless)\nSample_label (unitless)\nSa_ID (unitless)\ntime (Sample_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nLat (degrees_north)\nlongitude (degrees_east)\nBottom_depth (meters (m))\nNiskin (unitless)\nDepth_uncorr (m)\ndepth (m)\nTemp (degrees Celsius (°C))\nSal (PSU)\nDens_pot (kilogram per cubic meter (kg/m3))\nd3He (percent (%))\nd3HeEr (percent (%))\nd3HeFlag (unitless)\nHe4Conc (cubic centimeters at standard temperature and pressure per gram (ccSTP/g))\nHe4ConcEr (cubic centimeters at standard temperature and pressure per gram (ccSTP/g))\nHe4Flag (unitless)\n...
