Across the Nootka continental slope, gas hydrate related bottom-simulating reflectors are widespread and occur at depths indicating heat-flow values of 80 90 mW/m2. The storyline of FX’s hit new Tom Hardy series Taboo centers around an area of land known as Nootka Sound but is it really as significant as the show portrays In Taboo, Hardy’s character James. We infer the reflective zones beneath the two mounds are basaltic intrusions that create hydrothermal circulation within the overlying sediments. Pore fluids from a core at this mound contain predominately microbial methane (C1) with a high proportion of ethane (C2) yielding C1/C2 ratios < 500 indicating a possible slight contribution from a deep source. Measurements in the water column above one mound revealed a plume of warm water, and bottom-video observations imaged hydrothermal vent system biota. The order for Delaney’s death is officially given. The Nootka Treaty, or more formally the Treaty of Nootka, is a document signed between Horace Delaney and the Nootka tribe attesting property passage of Nootka Sound from the indigenous tribe to the Delaney family. Two seafloor mounds ~15 km seaward of the Nootka slope are underlain by deep, non-conformable high amplitude reflective zones. As Coop tries to tell him that Delaney’s death will hand Nootka to the Americans, the king replies, F Nootka. The bright spots are conformable to sediment layering, show opposite-toseafloor reflection polarity, and are associated with frequency-reduction and velocity push-down indicating the presence of gas in the sediments. Along the two main fault traces, seismic reflection data imaged bright spots 100 300 m below seafloor that lie above changes inbasement topography. Seismicity reaching down to the upper mantle is linked to near-seafloor manifestation of fluid flow through a network of faults. ![]() Here we combine observations from > 20 years of investigations toĭemonstrate the nature of fluid-flow along the NFZ, which is the seismically most active region off Vancouver Island. Geophysical and geochemical data indicate there is abundant fluid expulsion in the Nootka fault zone (NFZ) between the Juan de Fuca and Explorer plates and the Nootka continental slope.
