Marine Plankton during the Polar Night: Environmental Predictors of Spatial Variability
We studied the spatial patterns of the planktonic ecosystems at two Arctic sites strongly affected by Atlantic Inflow (FS, the Fram Strait; and BS, the Barents Sea). A high degree of similarity in the bacterial abundance (mean: 3.1 × 10 5 cells mL −1 in FS vs. 3.5 × 10 5 cells mL −1 in BS) was found...
