Short summary
Life on Earth is directly or indirectly linked to primary production (PP), the quantification of which poses a challenge. In our study we use the oxygen isotopes and oxygen–argon ratios technique to estimate PP in situ. To date this method has been used to assess PP in the ocean and we expand on its application to freshwater systems. Providing that the physical structure of the water column is constrained, this method presents a powerful tracer for atmospheric vs. photosynthetic oxygen input.
