Global Marine Barium Isotope Data from Barite Deposits

Barium isotope measurements from marine barite samples collected worldwide between 1970 and 2006. Analyses were conducted at the WHOI NIRVANA laboratory from 2016 to 2019. The dataset includes samples from cold seep, hydrothermal, and pelagic environments.

Use Cases

• Reconstructing past ocean productivity using barium isotope signatures in barite.
• Comparing barium cycling in different marine environments (cold seep vs. hydrothermal vs. pelagic).
• Calibrating barium as a paleo-proxy for ocean circulation and nutrient utilization.
• Investigating isotopic fractionation processes during barite formation and deposition.

Strengths

• Sample collection spans a 36-year period (1970-2006), providing temporal context.
• Analyses were performed in a dedicated laboratory (WHOI NIRVANA lab) over a 3-year period (2016-2019).
• Includes samples from three distinct marine depositional environments.

Limitations

• Exact row count, column names, and file size are unknown from all sources.
• Conflicting last updated dates exist between platforms (2006-01-01 and 2026-03-05).
• License and author information are not provided.
