摘      要：Information on tintinnid horizontal distribution in the Antarctic Continental Zone is *** the summer of 2019/2020,tintinnid diversity and horizontal distribution in surface waters were investigated in the Ross Sea and Amundsen Sea *** tintinnid species were found and the dominant species showed obvious horizontal distribution *** the Ross Sea,three tintinnid community groups were *** cristallina and Laackmanniella prolongata(group I)were dominant species and were mainly distributed in stations closer to the coast than were species in the other two *** gaussi(group II)and ***(group III)were mainly distributed in nearshore and offshore stations,*** the Amundsen Sea polynya,the dominant species ***,*** and Salpingella faurei(group I)were mainly distributed in stations closer to the coast than were species in the other two ***(group III)was mainly distributed in offshore *** distribution area where *** and *** were found in high abundance and abundance proportion of loricae with protoplasts was divided by the approximate boundary of the Antarctic Slope Front Current and Coastal Current in the Ross *** highest abundance proportion in the Ross Sea was the 32-36μm lorica oral diameter(LOD)size class(75.7%),and the 36-40μm LOD size class(56.0%)was found in the Amundsen Sea ***-salinity-plankton diagrams of the two seas revealed that temperature may be the main reason for species *** results contribute to a better understanding of horizontal distribution of the microbial food web,and serve as a baseline for future studies of pelagic community change in the Antarctic Continental Zone.
