在南加州地区(北纬33.4度，西经118.6度)的三个站点上，估计了有毒表层沉积物中的病毒产量和浮游病毒对悬浮颗粒的吸附。Viriobenthos的产量是使用无菌沉淀物和过滤后的孔隙水稀释技术估计的，该技术针对附着细菌和在孔隙水中自由生活的细菌的产量，以及仅针对附着细菌的产量。无细菌的潜在产毒率在1.7~4.6×10(8)VLP cm~(-3)h~(-1)之间，而附着细菌的潜在产毒率在0.4~1.1×10~(8)VLP cm~(-3)h~(-1)之间，表明沉积物中病毒的周转速率(1~5h)显著高于浮游病毒的周转速率(与24~48h相似)。浮游病毒被吸附到小(
Virus production in oxic surface sediments and virioplankton sorption to suspended particles was estimated across three stations in the Southern California region (33.4degreesN, 118.6degreesW). Viriobenthos production was estimated using a sterile sediment and filtered porewater dilution technique that targeted production from both attached bacteria and bacteria living free in the porewater, and attached bacteria alone. Potential virus production rates by bacteria free in the porewater ranged from 1.7 to 4.6 x 10(8) VLP cm(-3) h(-1), while attached bacteria had slower potential production rates of between 0.4 and 1.1 x 10(8) VLP cm(-3) h(-1), suggesting turnover rates of viruses in sediments (1-5 h) which are significantly higher than those of virioplankton (similar to24-48 h). Virioplankton adsorbed to small (
