(a) Annual mean sea ice concentration and sea ice thickness at the end of the simulations. Red lines in TSI100 indicate the presentday winter sea ice edge (Hirahara et al., 2014), and the contour in TSI094 indicates the simulated annual mean sea ice thickness (unit: m). The red shades on the land grid indicate that the monthly minimum snow depth exceeds 1 cm. (b) Annual mean surface shortwave albedo. -- physics.geo-ph

Metabolic reconstruction of major pathways in Synechococcus MAGs. The draft genomes for free-living and sponge-associated Synechococcus from NCBI were compared with the two MAGs from the anoxic YBH layer. The number or percentage of KEGG genes in these genomes was illustrated to mediate the metabolic network. α-Glucose-1P: α-Glucose-1-phosphate; G6P: α-D-Glucose 6-phosphate; F6P: D-Fructose 6-phosphate; FBP: D-Fructose 1,6-bisphosphate; 3-PG: 3-Phospho-D-glycerate; 1,3-BPG: 1,3-Bisphospho-D-glycerate; GAP: Glyceraldehyde 3-phosphate; Ribose-5P: Ribose 5-phosphate; Ribulose-5P: D-Ribulose 5-phosphate; Ribulose 1,5P2: D-Ribulose 1,5-bisphosphate; Fructose 1,6P2: D-Fructose 1,6-bisphosphate; Xylulose-5P: D-Xylulose 5-phosphate; PEP: Phosphoenolpyruvate; 2-PG: 2-Phospho-D-glycerate; DHAP: dihydroxyacetone phosphate. GY3P: glycerol-3-phosphate; GlcNAc-1-P: N-Acetyl-alpha-D-glucosamine 1-phosphate; GlcNAc-6-P: N-Acetyl-D-glucosamine 6-phosphate; GlcN-6-P: D-Glucosamine 6-phosphate. -- Applied and Environmental Microbiology
