| 1 | Difference of planktonic ciliate communities of the tropical West Pacific, the Bering Sea and the Arctic Ocean显示文摘Ciliates are important components in planktonic food webs,but our understanding of their community structures in different oceanic water masses is limited.We report pelagic ciliate community characteristics in three seas:the tropical West Pacific,the Bering Sea and the Arctic Ocean.Planktonic ciliate abundance had'bimodal-peak','surface-peak'and'DCM(deep chlorophyll a maximum layer)-peak'vertical distribution patterns in the tropical West Pacific,the Bering Sea and the Arctic Ocean,respectively.The abundance proportion of tintinnid to total ciliate in the Bering Sea(42.6%)was higher than both the tropical West Pacific(7.8%)and the Arctic Ocean(2.0%).The abundance proportion of small aloricate ciliates(10–20μm size-fraction)in the tropical West Pacific was highest in these three seas.The Arctic Ocean had higher abundance proportion of tintinnids in larger LOD(lorica oral diameter)size-class.Proportion of redundant species increased from the Arctic Ocean to the tropical West Pacific.Our result provided useful data to further understand ecology roles of planktonic ciliates in different marine habitats. | Chaofeng Wang Haibo Li Zhiqiang Xu Shan Zheng Qiang Hao Yi Dong Li Zhao Wuchang Zhang Yuan Zhao Gérald Grégori Tian Xiao | 2020 | Acta Oceanologica Sinica2020，39，4： | 2 |

| 6 | Pulsed export of carbon in the north-western Mediterranean Sea显示文摘The short term(hourly scale)variability of heterotrophic prokaryote(HP)vertical distribution and respiratory activity,was investigated in the north-western(NW)Mediterranean Sea.HP vertical distribution was determined on board by flow cytometry analysis of seawater samples collected by series of CTD casts.Cell counts and viability were determined for all samples.HP respiratory rates were determined later in the laboratory from filtered seawater samples(23 dm^(3))from 300-1150-m depth.The average cell viability was 94.8%±2.2%(n=240).There was no accumulation of dead cells,due to quick decay of damaged cells.In the epipelagic layer,three HP groups were distinguished,two(HNA1,HNA2)who se cells exhibited a high nucleic acid content and one(LNA)with low nucleic acid content cells.HNA2 was most populated at 50 m but not detected at 90 m and below,presumably aerobic anoxygenic photoheterotrophic bacteria(AAPs).The variability in HP abundance was mainly confined in the upper 80 m.A few secondary peaks of HP abundance were observed(80-150 m)in connection with abundance troughs in the surface layer.HP cells were continuously present in a wide layer around 500 m(mean 191×10^(3)cells/cm^(3)).Below this layer,HP abundance randomly exhibited peaks,coupled to respiratory rate peaks.The HP abundance and variability in the water column was suppressed during a strong wind event.The observed sporadic variability was tentatively interpreted through a pulsed carbon-export mechanism induced by the microorganism production of dissolved poly saccharide s,followed by flocculation and rapid sinking.This mechanism would thus contribute to(ⅰ)preventing organic matter accumulation in the epipelagic layer,(ⅱ)seeding the water column with live HP cells,and(ⅲ)supplying the aphotic water column with fre sh and labile organic matter.This important vertical flux mechanism needs further observations and modelling. | Michel DENIS Dominique LEFEVRE Melilotus THYSSEN Ian RJENKINSON Gérald GRÉGORI | 2023 | Journal of Oceanology and Limnology2023，41，1： | 0 |
