Abstract
A survey of heterotrophic bacterioplankton biolnass (BB; 4 to 64 mg C m-3), production (BP; 0.3 to 14.7 mg C m-3 d-l) and specific growth rates (p; 0.07 to 0 38 d.') as well as concentrations of nitrate (NO3-, 2O0C) waters distributed Inside and outside the shelf edge, respectively Inside the shelf edge, bacterial rate parameters (BP and p) were positively correlated with temperature but showed no correlation with POC, values of Q,, for BP and p were 2.7 and 3 3 respectively. From the shelf edge to the adjacent open ocean, bacterial rate parameters were positively correlated with POC only These results lmply that during the spring season, nlechanisms controlling the spatial patterns of bacterial rate parameters over the shelf area are system-dependent. It is concluded here that temperature plays a more dominant role than substrate supply inside the shelf edge; however, from the shelf edge to the open ocean, the situation is reversed
