Sediment Samples
![3 separate images of sediment samples](https://d9-wret.s3.us-west-2.amazonaws.com/assets/palladium/production/s3fs-public/styles/full_width/public/media/images/05_Jang_2019_Fig8a_Sample.jpg?itok=ZE1ibvZn)
Detailed Description
Once removed from the pressure core testing tool, this specimen shows that it is not a homogeneous sediment. The mostly fine-grained sample (dark sediment in all three images) easily breaks apart at a thin layer of coarse-grained sediment (light sediment on the inner core surfaces of images (i) and (ii). The light-colored coarse-grained layer can be seen running through the dark, fine-grained, clay-rich specimen in image (iii). Images like this assist interpretations of the measured data because gas hydrates in specimens like this are generally localized in the coarse-grained sediment, not evenly distributed through all sediment types.
