Figure 2. Distributions of temperature (A) and relative abundances of Nitrosopumilus (B), Lentimonas (C), and Nitzschia (D) in near-bottom waters. The presence of the cold and deep Bering-Chukchi Winter Water at the northeasternmost stations is apparent. Relative abundances of Nitrosopumilus, Lentimonas, and Nitzschia are highest in this water mass.
