Constant-pressure difference and constant-flow permeability tests were conducted on core samples from Ocean Drilling Program Legs 170 and 205 from the Costa Rica subduction zone representing pelagic carbonate and hemipelagic mud lithologies. Seven whole-round core samples from Sites 1040, 1253, and 1255 were tested for vertical permeabilities. The permeabilities of the pelagic carbonate sediments range from approximately 4 X 10 (super -16) to approximately 1 X 10 (super -15) m (super 2) . The permeabilities of the hemipelagic mud sediments vary from approximately 2 X 10 (super -18) to approximately 4 X 10 (super -18) m (super 2) . To further characterize the sediments, grain size, total carbon, and total inorganic carbon analyses were conducted.
