Bacterioplankton taxa compete for iron along the early spring–summer transition in the Arctic Ocean
Abstract Microbial assemblages under the sea ice of the Dease Strait, Canadian Arctic, were sequenced for metagenomes of a small size fraction (0.2–3 μm). The community from early March was typical for this season, with Alpha ‐ and Gammaproteobacteria as the dominant taxa, followed by Thaumarchaeota...
