Ocean acidification and warming effects on the macroalgal species Fucus vesiculosus forma mytili were simulated in the tidal benthic mesocosm facility at the AWI Wadden Sea Station on the island of Sylt, Germany (55°01'19.2''N, 8°26'17.7''E). The SY1 experiment in spring 2014 (11 weeks from early April to late June) was based on a "Temp X pCO2" full-factorial setup (ambient or delta 5°C temperature X ambient or 1000 ppm pCO2) resulting in 4 treatment levels à 3 replicates. The seawater parameters (temperature, pH, salinity, total alkalinity, pCO2) and seawater inorganic nutrient concentrations (silicate, nitrite, phosphate, ammonium, total nitrogen oxide, nitrate) were measured on a weekly basis. The biomass growth rates (RGR) of Fucus vesiculosus forma mytili were calculated over time, and its physiological parameters (carbon, nitrogen, CN ratio, mannitol) were measured at the beginning and end of the experiment.
