Vienna Standard Mean Ocean Water 2
  • etalonvesi, mis on kasutusel vesiniku ja hapniku stabiilsete isotoopide suhte mõõtmiseks
  • international reference sample of pure, distilled water used by scientists to measure the exact ratios of hydrogen and oxygen isotopes
rahvusvaheline etalonvesi
Usage examples
  • Rahvusvaheline etalonvesi (VSMOW2) on puhtaim destilleeritud vesi, mille isotoopne koostis on viidud võimalikult lähedale Maa ookeanivee keskmisele tasemele. Kuna esialgsed puhta VSMOW2 varud lõppesid, lõi Rahvusvaheline Aatomienergia Agentuur (IAEA) selle otsese järeltulija, mis on eelkäijaga isotoopselt identne.

Vienna Standard Mean Ocean Water 2
Usage examples
  • The Vienna Standard Mean Ocean Water 2 (VSMOW2) is the purest distilled water, with an isotopic composition adjusted to be as close as possible to the average level of Earth's ocean water. As the original stocks of pure VSMOW2 were depleted, the International Atomic Energy Agency (IAEA) created a direct successor that is isotopically identical to its predecessor.
