Based on a quantitative analysis of radiolarian in 80 surface-sediment samples from the northern area of Okinawa Trough, this paper reported the species composition and faunal assemblages characteristic of radiolarian, expounded the distribution pattern of radiolarian abundance and diversity in surface sediments from this area. In this paper, a preliminary study on the relation of the distribution and abundance of radiolarian to environmental factors, such as chemical and physical properties of the overlying masses (sea-surface temperature, salinity, nutrients and primary productivity) and the type and composition of sea-bed sediments was made. The radiolarian data was evaluated using a Q-mode factor analysis to identify different faunal assemblages and their geographic distributions, then the relationship between radiolarian assemblages and distribution of water masses, hydrographic boundaries such as frontal systems was analyzed. A new radiolarian-based transfer function to estimate mean-annual sea surface temperature and seasonal range were examined to test its success in the study area.
