Direct evidence of ocean hydrates has been obtained using in situ Raman measurements in Barkley Canyon, off Vancouver Island (Hester, 2007). The occurrence of sH in natural hydrate deposits has been inferred from gas analyses of recovered core samples from the Gulf of Mexico (Sassen and Macdonald, 1994 Yousuf et al., 2004) and confirmed by diffraction and NMR for samples from Barkley Canyon (Pohlman et al., 2005 Lu et al., 2007). 

Table 7.7 contrasts FHF and DLF hydrates. It should be emphasized that both hydrates are end-member types with the frequent occurrence of mixed types. For example, while Table 7.7 typifies Blake Ridge as DLF hydrates and Barkley Canyon as FHF hydrates, there is often a mixture of both types as shown in the Leg 204 study in the Cascadia Margin. As a second example, while the Gulf of Mexico is normally known for FHF hydrate deposits, Hutchinson et al. (2004) provide evidence for some elements that have DLF characteristics. 

Found by seafloor imaging and protrusions Can be structure I, II, or H hydrates Can have complex fauna with them Represented by Barkley Canyon hydrates... 

The technology developed in the Mallik production test should be transferred to recover hydrates from the sweet spots of high concentrations in the ocean, such as at Barkley Canyon or the Gulf of Mexico.
