a
For details on water masses at indicated viable cell (VC) levels in picoplankton abundance (PA), see text.
b
VA, viral abundance.
c
VP, viral production; VLP, virus-like particles. VP was calculated by dividing VA by VTT.
d
VTT, viral turnover time. VTT was calculated as the reciprocal of the viral decay constant according to the method of Suttle and Chen (44).
e
CR, contact rate.
f
BS, burst size. BS was calculated by dividing VP by CR (43).
