At shallow depths, the dissolved Cl- concentrations and dD and d18O values of the interstitial water reflect changes in the salinity and the isotopic compositions of seawater from the Last Glacial Maximum to the present. The presence of disseminated gas hydrates, which is well identified by discrete low Cl- anomalies within the gas hydrate stability zone, is accompanied by high dD and d18O values of the freshened fluids. This is consistent with incorporation of heavy isotopes into the gas hydrate lattice, which is also apparent in the signals observed at the ridge summit. Here, massive gas hydrate formation in the upper 20 meters below seafloor leads the formation of brines with dissolved Cl- concentrations as high as 1400 mM. The interstitial waters sampled near massive gas hydrates at the ridge summit are extremely depleted in D and 18O. Clay mineral dehydration within the deep prism results in a progressive decrease in Cl- and dD with depth. Dehydration temperature estimates based on those data likely suggest a progressive increase in the temperature of isotopic fractionation between clay and water with distance from the prism toe. The oxygen isotope data probably reflect the combined effects of clay dehydration, carbonate precipitation, and alteration of oceanic basement; however, there are not enough data to constrain the relative contribution of these processes to the observed signals. -125.1525 -125.07393000000002 44.56843 44.5863 -125.13024083333335 44.57659041666667 2002-07-13T01:00:00 2002-09-01T00:00:00 0.0 531.12 ODP Ocean Drilling Program https://www-odp.tamu.edu:443/ Ocean Drilling Program, Texas A&M University ODP http://www-odp.tamu.edu/ https://ror.org/01f5ytq51 204-1244B 44.58616 -125.11986 North Pacific Ocean -896.0 2002-07-13T01:00:00 2002-07-13T12:45:00 Leg204 Leg204 2002-08-06T00:00:00 2002-08-06 2002-10-04T00:00:00 2002-10-04 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Tréhu, Anne M Tréhu, Anne M doi:10.2973/odp.proc.ir.204.2003 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Drilling/drill rig DRILL 54.1 m 56.85 m 6 cores;
