R/V Professor Bogorov Cruise report: Cruise 37 POSETIV - Paramushir-Okhotsk Sea Expedition to Investigate Venting, Vladivostok - Vladivostok, September 23 - October 22, 1994
Since the discovery of fluid venting in the late seventies the processes involved in the marine geochemical cycle, especially those of fluid and gas flux through the sediment-water interface have become a new and exciting area of interest and research. Today numerous vent fields have been discovered...
