However, except for a few sites, DURA were generally depleted in the SML of our study (Fig. 3c, Table S1). Bacterial abundance in the SML of freshwater and open melt ponds was low compared to open sea samples (Fig. 2d). In general, bacteria were not enriched in the SML (Fig....
Genetic data is increasing in two dimensions. On one hand, moonshot initiatives with a “sequence everything” philosophy such as the Earth BioGenome Project [4] and the Tara Oceans Project [5] are sequencing a diverse range of species and microbial communities in a variety of environments [6...
