Cariaco Basin, core-top sediment PL07-22Bx
Caribbean Sea, Venezuelan shelf, Venezuela

- Type
- Sediment
Core top PL07-22Bx (site 1 in Fig. 2), below 656 m of water. Authigenic fractions of the six sites (mean -5.4 without site 2, 300 to 886 ng/g Tl) reproduce basin water above the chemocline (-5.9 to -5.2); silicate fractions about -2.8 (Owens et al., 2017). Coordinates from Table 1, western longitudes.
