Short summary

Hydrogen peroxide, H₂O₂, is formed naturally in sunlight-exposed water by photochemistry. At high concentrations it is undesirable to biological cells because it is a stressor. Here, across a range of incubation experiments in diverse marine environments (Gran Canaria, the Mediterranean, Patagonia and Svalbard), we determine that two factors consistently affect the H₂O₂ concentrations irrespective of geographical location: bacteria abundance and experiment design.
