Figure Lengend Snippet: The present list of instruments connected to the AquaBox. An example of the data can be found in Fig. 4 and the data from optical measurements (photosynthetic pigments, colored dissolved organic matter, and photochemical efficiency) and temperature and salinity in: https://data.mendeley.com/datasets/8ssgdbc7jt/4 .

Article Snippet: How the data were acquired , A mesocosm experiment at the SW coast of Finland set up in 2.2 m 3 plastic bags treated with addition of HuminFeed (Humintech GmbH, Grevenbroich, Germany) and inorganic nutrients. Dissolved inorganic nutrients were determined by colorimetric methods using a photometric analyzer (Thermo Scientific Aquacem 250) and a spectrophotometer (Hitachi U-1100). Particulate nutrients and chlorophyll a by filtration and subsequent analysis of the filters either colorimetrically, by an element analyser (Shimadzu TOC-VCPH) or mass spectrometer (Europa Scientific ANCA-MS 20-20 15N/13C). Dissolved inorganic carbon (DIC) measurements were done using a DIC Analyzer (Model AS-C3; Apollo SciTech, USA), with a LICOR LI-7000 CO 2 analyzer (LI-COR, USA). Colored dissolved organic matter absorption aCDOM(λ) were determined over the range of 200 to 800 nm using a spectrophotometer (Shimadzu UV-2450). Different groups of phytoplankton were determined by flowcytometry (Sysmex- Partec Cube 8), and the primary and bacterial production by incubation with radiolabeled isotopes and the uptake determined with a scintillation counter (Wallac Win Spectral 1414)..
