FL free-living, PA particle-associated. Bacterial sequences were normalized to gene length. Estimated percentages were calculated using recA abundance. Data shown are means ± SD.
^aMean of two replicates, which are from different cruises but the same station (September 2016 and March 2017).
^bMean of two replicates, which are from the same cruise (March 2017).
^cValues from one cruise when another value is zero.
