Analysis of the 155 radiolarian taxa recorded in 48 plankton samples collected by means of 0–100 m tows between January and November 1972 in the California Current region revealed three faunal zones. The northernmost of these was dominated by Subarctic-transitional

Simple Summary Phylum Retaria and Phylum Cercozoa consists of the siliceous planktonic organisms, commonly referred to as Radiolarians, were investigated from 200 m depth to the surface in the eastern Indian Ocean (80.00°–96.10° E, 10.08° N–6.00° S) during

The plankton radiolarian community was investigated in the spring season during the two-month cruise ‘Shiyan1‘ (10 April–13 May 2014) in the Eastern Indian Ocean. This is the first comprehensive plankton tow study to be carried out from 44 sampling stations
