... neon gas will be injected in one filter, and its diffusion will be monitored by three other filters. By re-using existing boreholes dating from the 1990s, the NEMESIS experiment will continue to provide new diffusion data for the next five years. The most widely accepted solution for the long...

... at room temperature. Argon was trapped for 20 minutes on an activated charcoal-filled stainless-steel finger cooled to −196°C using liquid nitrogen. Neon was then trapped on activated charcoal in a cryostatic cold head at 30 K for 10 minutes; the unabsorbed He was pumped out then the Ne was released...

... contact of a gas phase (e.g. Ballentine et al. 1991 ; Ballentine and Sherwood Lollar 2002 ; Barry et al. 2016 ). Neon concentrations similarly show two distinct patterns. Within all the helium-rich NTDZ samples, neon shows a small range of concentrations from 1.1 × 10 −5 to 1.88 × 10 −5  cm 3...

... water (~5 × 10 –8 ). This observation further confirms helium is nonatmospheric in origin. Neon and argon isotopes of the samples have much narrower ranges that are mostly similar to modern air. In summary, the results show that neon and argon are dominantly atmospheric and likely transported by air...

... and nitrogen concentrations result from interaction of a hydrocarbon-rich gas with at least two pore-water masses containing dissolved helium and nitrogen. Neon isotopic ratios demonstrate that helium concentration in pore water was sufficiently low for porous sediment to generate the helium over several...
