During the cruise of RV “Akademik Oparin” an assessment of radioecological state of the Pacific Ocean east of Japan and Kuril Islands as well as Okhotsk and Japan seas was conducted in connection with polluted water discharge from Fukushima-1 NPP. Results of the first samples of surface analysis showed tritium content as 0.36–0.78 tritium units (0.04–0.09 Bk/l). The highest concentrations were found in the Kuroshio Extension stream and in the area of Southern Kuril Islands. Meanwhile it is ten thousands time lower than radio security norm. In the cruise samples of water, bottom sediments and marine biota were prepared to analyze radioisotopes of cesium, strontium, led, radium and others. Large volume of hydrographic, chemical, biological, gas-geochemical, mercury measurements and samplings was implemented. Mooring systems were recovered and deployed again. New data on water state and dynamics of the study region, as well as biogeochemical parameters and their interannual variability in association with climate change and increasing anthropogenic load were received.

2. Fig. 1. Scheme of work of the expedition of the TOI Far Eastern Branch of the Russian Academy of Sciences on the NIS Akademik Oparin (flight No. 71) in June–July 2024. The figures indicate the content of tritium (in tritium units) according to the results of the analysis of the first samples of surface waters. The dotted line marks the boundaries of the Kuroshio current, cyclonic (C1–3) and anticyclonic (A1–5) vortices. Isobaths are indicated in meters. 1 – the ship's route; 2 – oceanographic stations; 3 – the position of the ABS; 4 – stations for sampling large volumes of water for radionuclides from subsurface horizons; 5 – stations for direct spectrometric measurements; 6 – ports of entry and approaches.
