Figure F30. Volume-pressure-time plots for PCS deployed at Site 1247. A. Note that Core 204-1247B-4P was not placed on an ice bath since no gas hydrate was expected. B. Note that no evidence of gas hydrate decomposition is observed in Core 204-1247B-16P, although methane concentration exceeding solubility in situ was measured.
