The Kiel Outdoor Benthocosm infrastructure (Kiel, Germany,N 54°19.8'; E 010°09.0') allows combining natural in-situ fluctuations on all environmental variables with the controlled manipulation of treatment factors. The environmental fluctuations are admitted by a continuous flow-through of fjord water. The treatment is applied by delta-treatments which shift the mean of target variables (temperature and pH in this case) while maintaining the frequency and amplitude of natural fluctuations. The data presented here show the treatment levels and the continuously logged temperature and pH conditions in the experimental tanks. The dynamics of temperature and pH are driven by (i) in situ variability, (ii) the treatments imposed and (iii) the biology of the biota in the tanks. These contained macroalgal communities with associated mesograzers, mussels, and sea stars. The data set comprised 5 experimental runs: spring experiment (4.4.-19.6.2013), summer experiment 1 (4.7.-17.9.2013), autumn experiment ... : Supplement to: Wahl, Martin; Buchholz, Björn; Winde, Vera; Golomb, Dar; Guy-Haim, Tamar; Müller, Jens Daniel; Rilev, Gil; Scotti, Marco; Böttcher, Michael Ernst (2015): A mesocosm concept for the simulation of shallow underwater climates: The Kiel Outdoor Benthocosms (KOB).
