Figure 1. The Ocean Barcode Atlas query schema.
Figure 2. Graphical results produced by the Ocean Barcode Atlas.
Figure 3. The Interactive world map of the barcodes abundance distribution using a range for an environmental variable.
Figure 4. Case study 1. Biogeography of the Symbiodiniaceae V9 rDNA metabarcodes (A) and scatter plot of their relative abundance (B) in the open ocean among the total reads of the eukaryotic community across different latitudes on surface samples and plankton size fractions (piconano: 0.8–5 µm; micro: 20–180 µm; meso: 180–2,000 µm).
Figure 5. Case study 2. Biogeography of prasinophytes Clade VII (A) and mamiellophyceae (B) V9 rDNA metabarcodes.Scatter plots show their relative abundance across different latitudes in surface samples for pico-nanoplankton size fraction (0.8–5 µm) corresponding to prasinophytes Clade VII (C) and mamiellophyceae (D).
Figure 6. Case study 3. Ecological analyses of Diplonemids V9 rDNA metabarcodes. Beta-diversity analysis (A) showing a non-metric multidimensional scaling analysis based on pairwise Bray-Curtis distances among samples (using depth as the environmental variable). Alpha-diversity analysis (B) showing boxplots of OTU number versus sampling depth and Shannon index versus sampling depth.
