From: Bacterioplankton reveal years-long retention of Atlantic deep-ocean water by the Tropic Seamount
Bacterioplankton distributions in the water column at Tropic Seamount. (a) Comparison of bacterioplankton concentrations between the water column in Tropic Seamount periphery (St. 1 and 13) and the North and South Atlantic gyres (NAG and SAG, respectively). (b) Comparison of bacterioplankton concentrations between samples collected within 1 m of the seamount surface by a remote operated vehicle (ROV), at Tropic Seamount (St. 2–12) and in its periphery (St. 1). Dotted horizontal lines (a,b) indicate the five water layers defined. (c) Comparison of mean bacterioplankton concentrations in the five water layers between Tropic Seamount and its periphery. Error bars indicate single standard deviations of mean values. The results of the corresponding statistical analyses are presented in Supplementary Table S4. The corresponding sampling locations are shown in Fig. 1.
