Without nuclei, we simply would not exist, and it is important to understand why!NUPEX provides a free database of knowledge, created and maintained by expert nuclear physicists from all over Europe.In February 2014, the researchers visited massive coral colonies at Heron Reef in the southern Great Barrier Reef, located off the northeastern coast of Australia.The authors used scuba and pneumatic drills to penetrate the growing coral colonies and retrieve core samples.Nuclear Physics is the study of the properties and behaviour of nuclei and particles, ranging from tiny quarks to giant explosions deep in space.Nuclear physics is important in a vast variety of situations, from understanding how the Sun provides the energy for life on this planet, to nuclear power plants and radiation therapy.Strontium (Sr) atoms are sized similarly to calcium and have the same ionic charge, so they also get incorporated into coral skeletons.The abundance of strontium in newly forming coral depends on the temperature of the seawater that bathes it—the colder the temperatures are, the more strontium infiltrates coral skeletons as they form.

For example if you have a fossil trilobite and it was found in the Wheeler Formation.To collect new data that could improve these models, turned to records captured in ancient coral beds.As stony corals grow, they build their skeletons from calcium (Ca) in the surrounding seawater.I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.
