Shark lasers could help save vulnerable species
Researchers at the University of Melbourne used laser technology and geochemistry to accurately determine the age of speartooth sharks and assess their environment's health. The method involves analyzing shark vertebrae using laser ablation inductively coupled plasma mass spectrometry.
A team of researchers in Australia has developed a new method to determine the age of speartooth sharks and assess their environment's health. The method combines laser technology and geochemistry to analyze shark vertebrae. By using X-ray scanning and laser ablation inductively coupled plasma mass spectrometry, the team linked geochemical information to the shark's environment. The researchers found that the previous method of vertebrae band counting is less accurate for age estimation. The new approach provides a more accurate way to estimate shark age and monitor population health. This can lead to more effective conservation strategies for vulnerable shark species.
