Sample-related information| Core name | NBP9902-PC04 |
| Top depth (m) | 0.08 |
| Bottom depth (m) | 0.1 |
| Lithology | Dark greenish gray (Gley 1, 4/1), stiff, silty mud with an increasing subangular to subrounded sand and abundant (> 50%), subangular to subrounded, very fine to rare very coarse pebble component down core. Several silty mud layers and lenses, with abrupt contacts, occur in the upper part of the core. Subangular to subrounded, very fine to rare very coarse pebbles occur singularly and within a layer in the core. |
