Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that oxygen isotope exchange occurs between dissolved carbon dioxide and water?

Yes. Multiple studies demonstrate that oxygen isotope exchange occurs between dissolved or gaseous carbon dioxide and water, a process that can occur both abiotically and via enzymatic catalysis in various environments.

The analysis

Papers [0] and [4] explicitly discuss and investigate oxygen isotope exchange between carbon dioxide and water (in flasks and soils respectively), fully supporting the claim. The remaining papers cover unrelated topics such as photocatalysis, ocean dissolved oxygen budgets, phosphorus isotope exchange, or carbon monoxide kinetics, and are therefore omitted as tangential.

Oxygen isotope exchange between water and carbon dioxide in soils is controlled by pH, nitrate and microbial biomass through links to carbonic anhydrase activity

2021

Investigates the rate of oxygen isotope exchange between soil water and carbon dioxide, noting it is catalyzed by carbonic anhydrase in soil pore spaces.
