Distributions of 32P and 33P in the western North Pacific with multiple-unit in situ large-volume filtration systems

Geographical distributions of cosmogenic natural radionuclides 32P and 33P in surface seawater were investigated in the western North Pacific (0 to 48.3 N). An in situ large-volume filtration system equipped with adsorbents for dissolved P was used to collect the nuclides in the water column. Radioa...
