Photosynthesis, respiration and reaeration in a stream with complex dissolved oxygen pattern and temperature dependence.

Highlights: [•] Complex DO diel curve was found by high frequency data records. [•] Night profile comprises sag and quasi stable sections previously undescribed. [•] P av , R and k a were estimated and DO modeled in a robust basis. [•] Temperature and particular stream characteristics influenced DO dynamics. [•] Useful insights for dissolved oxygen dynamics in shallow streams are provided. [Copyright &y& Elsevier]
