CO2 in the wild

I recall reading in the planted tank column in an issue of TFH several years back that naturally occurring CO2 concentrations in certain natural aquatic environments, such as some European streams, are higher than those of non-CO2 tanks kept by hobbyists.

I'm wondering if anyone has particular data on CO2 concentrations in wild aquatic environments. In particular I'm curious about that of South East Asian peat swamps and black water environments.

Bump. That is a really cool question that I would like to know the answer to as well.

Spring water is often very high in dissolved CO2. If a stream is fed by springs this can be a source of carbon.

In a stable environment the CO₂ concentration in the water is directly related to the ruling partial CO₂ gas pressure in the surrounding atmosphere, which is why spring water can have a high CO₂ concentration.
This also means that - if you know the fluctuations of the CO₂-level in the local atmosphere - you can calculate the CO₂ variations in the water.
