Abstract: The ocean and atmospheric interaction within the Pacific Ocean is complex and compounded by various intricacies. To better comprehend its dynamic nature, the West Pacific Warm Pool was studied as it contains the warmest water in the Pacific Ocean and drives the continuous atmosphere convection and ocean circulation from the east to west Pacific that also inadvertently affects the climate worldwide. The paleoceanographic proxy used to reconstruct past oceanic, climate and environmental events was a microfossil plantonic protozoa known as Radiolarians. The microfossils of polycystine radiolarians comprises of an opaline silica skeleton that can withstand dissolution fairly well and remain adequately preserved within the marine debris. This research reviews the radiolarians taxa within samples taken along sections of the marine sediment core, MD97-2140, collected at 2°02’N 141°46’E, water depth of 2547 meters.
