The higher phosphate concentration in the deep North Pacific compared to the deep South Pacific is primarily due to differences in ocean circulation and biological processes. The North Pacific has more extensive upwelling and nutrient recycling, which brings phosphate-rich waters to the surface, while the South Pacific experiences less upwelling and lower biological productivity. Additionally, the North Pacific's oceanic currents facilitate the transport of nutrients from continental margins into the deep ocean, further increasing phosphate levels. In contrast, the South Pacific's more isolated waters lead to lower nutrient concentrations overall.
