Figure 3. Distributions of nutrients (nitrate + nitrite) (A) and relative abundance of Thalassiosira (B) in near-bottom waters. The southernmost samples display high nutrient concentrations, similar to the concentrations found in the northern Bering-Chukchi Winter Water. Though these samples share similar nutrient concentrations, Thalassiosira appears to favor the Bering-Chukchi shelf waters seaward of the Alaska Coastal Current, while remaining rare in the older, colder Bering-Chukchi Winter Water.
