Method (primary source abstract:) "A suite of pneumatically operated sampling devices was employed to investigate distributional patterns of marine bacteria at the millimetre scale."
Comments "Likely as a consequence of...heterogeneity, bacteria are also heterogeneously distributed, with recorded variations in cell concentration of up to 20-fold over 10 to 30 mm (primary source). Thus, despite its superficial homogeneous appearance, the water column can have a rich physical, chemical, and biological microarchitecture, not unlike that of environments dominated by surfaces, such as sediments or animal hosts."
