Fish in the ocean dating questions for dating my son

We have a long history of using radiochemical dating of calcified structures like corals and molluscs.The same underlying concepts apply to fish otoliths, and are based on well-established physical principles governing radioactive decay. 🐟 One of the most famous categories of puns on the internet, and that’s what this Punpedia entry is all about.Fish puns overlap a little with the entries on shark puns, beach puns, boat puns and water puns, so feel free to check out those articles for some related wordplay.This was very difficult and near the limits of both 1) what I can extract with the micromill (with confidence) and 2) what NOSAMS can measure for radiocarbon with a reasonable level of precision.

Virtually all have been used to validate more traditional, less expensive methods of age determination.Age has been estimated from growth zone counting in otoliths and I have extracted a series of otolith cores from fish of differing estimated age that have been tested with bomb radiocarbon dating.These samples were measured for radiocarbon at Woods Hole Oceanographic Institution at the National Ocean Sciences Accelerator Mass Spectrometry Facility (NOSAMS) and the final paper is in press.We know the fixed half-lives of the parent and daughter isotopes.We can use the ratio between them as an index of elapsed time since incorporation of the parent isotope into the otolith.
