3He/4He and 4He/20Ne ratios in pore water and gas in Pacific deep-sea sediments, supplement to: Sano, Yuji; Wakita, Hiroshi (1987): Helium isotopes and heat flow on the ocean floor. Chemical Geology: Isotope Geoscience section, 66(3-4), 217-226

Yuji Sano & Hiroshi Wakita
We have measured the 3He/3He and 3He/20 Ne ratios of thirty-nine pore water and gas samples in deep-sea sediments collected at twelve sites on the Pacific Ocean bottom during the cruises of Deep Sea Drilling Project Legs 87, 89, 90 and 92. The 3He/4He and 4He/20Ne ratios vary from 0.000000215 to 0.00000165 and from 0.29 to 20, respectively. He in the sample is composed of four components: (1) atmospheric He dissolved in seawater; (2) atmospheric...
