Data to Prior exposure to stress allows the maintenance of an ecosystem cycle following severe acidification

This freshwater mesocosm study was conducted in 19 out of 110 mesocosms at the Large Experimental Array of Ponds (LEAP) at the Gault Nature Reserve in Mont-St-Hilaire, QC, Canada (45°32' N, 73°08' W, 122 m a.s.l.) between May and October 2018 for a total of 147 days. On 24 May 2018, the mesocosms (1100L stock tanks, Rubbermaid, Huntersville, NC, USA) were filled with approximately 1000 liters of unfiltered lake water via a pipeline from oligotrophic Lac Hertel, located 1 km upstream of the experimental facility. 

These data consist of two datasets that were used for our paper. 

Dissolved oxygen as measured with data loggers (MiniDOTs, PME, Vista, California, USA) in 12 mesocosms
Phytoplankton biomass as measured with a FluoroProbe (bbe Moldaenke, Schwentinental, Germany) in 19 mesocosms
