Table S1. Sampling data, environmental factors measured in the field, biomass data and pigment composition. Microbial biomass was collected on precombusted Whatman® GF/F glass fibre filters (pore size ~ 0.7 μm) using a peristaltic pump with a filtration rate of 50–100 ml · min−1. The filters were immediately frozen in liquid nitrogen and stored at −80°C. Concentrations of chlorophyll a (Chla) and the carotenoids echinenone (Echi) and zeaxanthin (Zea) were measured by high-performance liquid chromatography according to Andersson and colleagues (2003). Measurements of particulate organic carbon (POC) and particulate nitrogen (PN) from the filters were carried out with a CHN-900 analyser (Leco, USA).
