Abstract:
Six peepers were deployed by the German submersible Jago in sediment of the methane seep area off northwestern Svalbard at the gas hydrate stability limit. Peeper 1 and 2 were deployed in a sulfur bacteria mat, Peeper 3 and 4 were in a siboglinid (pogonophoran) worm field, and Peeper 5 and 6 were at a gas vent. The distance between the three groups was about 1 meter. After 10 days incubation, peeper were retrieved and porewater solutes were measured in the peeper samples.
