a Stations visited in the Atlantic between 62°S and 47°N and in the Pacific Ocean between 52°S and 59°N. The color code of the stations refers to their affiliation to biogeographic provinces according to Longurst81 in the Atlantic (North Atlantic drift (NADR), North Atlantic subtropical gyre (NAST), North Atlantic tropical gyre (NATR), Western tropical Atlantic (WTRA), South Atlantic gyre (SATL), Southwest Atlantic Shelves (FKLD), Subantarctic water ring (SANT), Antarctic (ANTA), Antarctic polar (APLR)) and the Pacific Ocean (BERS: Bering Sea; PSAG: Pacific subarctic gyre; NPPF: north Pacific polar frontal region; NPST: north Pacific subtropical gyre; NPTG: north Pacific tropical gyre; PNEQ: Pacific north equatorial counter current; PEQD: Pacific equatorial divergence; SPSG: south Pacific subtropical gyre; SSTC: south subtropical convergence; NEWZ: New Zealand coastal province; SANT: subantarctic province). Stations are overlaid on maps of both oceans with annual mean sea surface temperatures (SST) (https://oceandata.sci.gsfc.nasa.gov). Maps are modifications of versions published previously according to CC BY8,9. b Relative proportions of homogeneous and heterogeneous selection, homogenizing dispersal and dispersal limitation and drift on assembly of the 0.2–3 µm, 3–8 µm and >8 µm prokaryotic communities in the epipelagic (20 m to DCM depth) of the Atlantic and Pacific Ocean. c Richness of the ASVs of the V4-V5 region of the 16 S rRNA gene of the three size fractions of the prokaryotic communities in the epipelagic Atlantic and Pacific Ocean. Points indicate single samples and the line the smoothed mean value. Source data are provided as a Source Data file.
