Relative composition (mol%) of dissolved combined carbohydrates (dCCHO) to determine a change in quality within the upper 100 m of the Fram Strait between summer and autumn. The summer samples were collected from July 16th to July 23rd, 2018 and autumn samples from September 16th to October 4th, 2018. The colour shows the two seasons: summer in blue and autumn in black. The shapes show the five depths: Surface (circle), above DCM (square), DCM (rhombus), below DCM (triangle faced up) and 100m (triangle faced down).;Relative composition (mol%) of dissolved hydrolysable amino acids (dHAA) to determine a change in quality within the upper 100 m of the Fram Strait between summer and autumn. The summer samples were collected from July 16th to July 23rd, 2018 and autumn samples from September 16th to October 4th, 2018. The colour shows the two seasons: summer in blue and autumn in black. The shapes show the five depths: Surface (circle), above DCM (square), DCM (rhombus), below DCM (triangle faced up) and 100m (triangle faced down).;Stations within LTER HAUSGARTEN observatory and the associated CTD cast sampled in the upper 100m of the Fram Strait in the summer and autumn. The summer samples were collected with the RV Polarstern (PS114) from July 16th to July 23rd, 2018 and autumn samples with the RV Maria S. Merian (MSM77) from September 16th to October 4th, 2018. CTD dataset is available doi.pangaea.de/10.1594/PANGAEA.907467 and discrete samples are available: doi.org/10.1594/PANGAEA.915751.;Statistical analysis run for the study on all discrete parameters for the Fram Strait between summer and autumn. The summer samples were collected from July 16th to July 23rd, 2018 and autumn samples from September 16th to October 4th, 2018. The tests include: t-test, a statistical mixed model, an analysis of variances (ANOVA) and multiple contrast tests (MCT). MCT we only conducted if the ANOVA was significant. For details please refer to Methods section. Abbreviations for the parameters are: dissolved organic carbon (DOC), dissolved combined carbohydrates (dCCHO), dissolved hydrolysable amino acid (dHAA), particle area of transparent exopolymer particle (TEP Area), particle area of Coomassie Blue stainable particles (CSP Area), bacterial abundance (BA), low nucleic acid bacteria (LNA), high nucleic acid bacteria (HNA) and bacterial production (BP). "AT" refers to Atlantic water and "IW" to intermediate water based on temperature-salinity characteristics.
