Sedimentary record of radiolarian biogeography in the equatorial to antarctic western Pacific Ocean.
Analysis of 18 surface sediment samples from between 1o and 64oS, along approx. 180oE, yielded 195 Recent radiolarian taxa. Clustering of the species and the samples, and further examination of the distribution patterns of radiolarian abundances, allowed definition of five climatic zones (tropical t...
