Trace element and boron isotopic composition of Drake Passage deep-sea corals
Changes of circulation pattern in the Southern Ocean have been invoked to explain a significant portion of the increase in the atmospheric carbon dioxide during the last deglaciation. However, the accurate timing and thus underlying mechanisms of these changes are still controversial, requiring knowledge of different water masses movements with absolute age constraints. Aragonitic scleractinian deep-sea corals, recovered from a broad range of depths in the Drake Passage, provide a unique opportunity to investigate Southern Ocean ventilation with precise U-Th age control. This data submission includes trace element and delta11B for Drake Passage corals.
Funding was provided by the NERC standard grant NE/N003861/1.

- Statement
- Limits of detection for trace metal analyses by ICP-MS were calculated for each analytical batch using the average blank (in counts per second) plus 5 standard deviation of the blank. Sample results that returned below this threshold within each run are quoted as ''<LOD''.
