Phys.org  June 25, 2024 One way to track ocean currents is by tracing, or tracking, radioactive isotopes that humans began generating in the 1950s during nuclear testing. An international team of researchers (Switzerland, Canada) used the transit time of radionuclides to learn about the decades-long path that water from the Atlantic Ocean takes into the Arctic Ocean’s Canada Basin. Transit Time Distribution (TTD) model mean ages indicated water takes 25–35 years to reach the Canada Basin from the entrance of the Arctic. Mode ages obtained from the model yielded shorter transport times of 20–32 years. These age estimates agree with […]
