This season, 40 gray whale deaths have been recorded, primarily among young and adult specimens. Jorge Urbán, head of the Marine Mammal Research Program at UABCS, noted that while this number is within the expected range, it is unusual that the deceased whales are not calves.
A total of 44 fish with cesium levels above 100 becquerels per kg have been found in the Fukushima plant port between May 2022 and May 2023, Tepco confirmed, with 90% of those caught in or near the inner breakwater. Other specimens identified as having particularly high radioactivity were an eel with 1,700 becquerels per kg, caught in June 2022, and rock trout, with 1,200 becquerels in April 2023.
Due to a suitable residence time in the ocean, Fukushima-derived radionuclides will provide useful tracers for isotope oceanography studies on the transport of water masses during the next decades in the NW Pacific Ocean.
