A modified method for measurement of dissolved gases and ions in pore waters extracted from sediment cores with no air contact has been developed. Sediment is transferred from sealed core liners to a filter press sediment squeezer through a CO 2 ‐ or He‐flushed interlock. Pore water intended for dissolved gas analysis is squeezed directly into a He‐flushed sampler‐stripper, which is then mounted directly on a gas chromatograph, stripped for gases by the helium carrier gas, and analyzed for Ar, N 2 , and CH 4 or other gases.
