Fig. 2: Basin-scale biogeography shows variable environmental patterns but stable ecotype frequencies.

From: Basin-scale biogeography of Prochlorococcus and SAR11 ecotype replication

Fig. 2

Measured environmental variables include temperature (blue) and interpolated nutricline depth (green) as well as N- (yellow), P- (purple), and Fe-stress (red) indices (Ω). Note that nutricline depth was measured via CTD cast aboard I07N and I09N but had to be estimated via World Ocean Atlas seasonal averages along the C13.5 transect due to COVID-19-driven cancellations. Frequency of Prochlorococcus and SAR11 ecotypes was measured by relative single-copy core gene (SCCG) coverage.
