Planktonic Tintinnid Community Structure Variations in Different Water Masses of the Arctic Basin
Information on tintinnid community structure variations in different water masses in the Arctic Basin is scarce. During the summer of 2020, tintinnid diversity and vertical distribution were investigated in the Arctic Ocean. A total of 21 tintinnid species were found in five water masses and each wa...
