Prokaryotic variables from a indoor-mesocosm experiment measured during the winter in the Northern Bothnian Sea

The primary data was collected during the indoor-mesocosm experiment conducted in March 2020 at Umea Marine Science Centre, Umea University, Sweden situated in the Northern Bothnian Sea (63° 34ˈN, 19° 50ˈE). A full factorial experiment was set with temperature and the addition of nutrients as treatment factors with a natural pelagic food web containing all trophic levels except fish. A total of four experimental treatments were set up with three replicates each: C, control (1°C, no additions); N (1°C,+ nutrients); T (10°C, no additions) and TN (10°C, + nutrients). For each treatment, eight different samplings were done in triplicates. The variables in the data include the prokaryotic abundance (PA), growth (PG), respiration (PR), specific prokaryotic respiration (ρ), specific growth rates (µ), growth efficiency (PGE), dissolved organic carbon (DOC), total dissolved phosphorus (TDP) and total dissolved nitrogen (TDN).

主要数据采集于2020年3月在瑞典于默奥大学于默奥海洋科学中心开展的室内围隔实验（indoor-mesocosm experiment），该中心位于北博滕海（63°34′N，19°50′E）。本研究设置了以温度和营养盐添加为处理因素的完全析因实验（full factorial experiment），实验系统为包含除鱼类外所有营养级（trophic levels）的自然中上层食物网（pelagic food web）。共设置4个实验处理组，每组3个重复：C对照组（1℃，无添加）、N组（1℃，添加营养盐）、T组（10℃，无添加）及TN组（10℃，添加营养盐）。数据中的变量包括原核生物丰度（prokaryotic abundance，PA）、生长量（PG）、呼吸作用（PR）、比原核呼吸速率（specific prokaryotic respiration，ρ）、比生长速率（specific growth rates，µ）、生长效率（PGE）、溶解有机碳（DOC）、总溶解磷（TDP）和总溶解氮（TDN）。
