Specifically the line between the Holocene (the past 12,000 years since the last glacial epoch) and the Anthropocene Epochs (the most recent period in Earth's history when human activity started to have a significant impact on the planet's climate and ecosystems). The marker they are looking to make official is one that will survive for thousands of years and be independant of paper and electronic records, buildings, etc. The paper fleshes out the properties and expected long term behaviour of the approximately 3 tons of Pu-239 released to the environment from above ground tests, which commenced in 1945 CE, and peaked in the Northern Hemisphere between 1961 and 1962 CE prior to being banned in 1963.
