  abstract = {{B}acterioplankton biomass and production were determined over the whole water column of a eutrophic, a mesotrophic and an oligotrophic site (2300, 3200 and 4500 m deep) in the tropical {NE} {A}tlantic {O}cean during a {EUMELI} cruise in {M}ay-{J}une 1992. {T}his resulted in an exceptionally large amplitude of data, with abundance, biomass and production. {T}hese data were analyzed in order to determine whether bacterioplankton was controlled by bottom-up or top-down processes. {R}egressions of log-transformed bacterioplankton biomass versus log-transformed production were tested at the different sites and in different layers. {S}lopes of 0.40-0.55 suggest that bacterioplankton is moderately controlled by bottom-up processes increasing from the eutrophic coastal site to the open ocean oligotrophic site and from surface layers (< 250 m) to deep waters. {T}hese conclusions are in agreement with other indices of bottom-up control like cell size, doubling times of the biomass, per cent of active cells, and relationships of bacterial biomass versus phytoplanktonic biomass and production.
