How stable-isotope fingerprints trace kelp carbon from a particular forest into food webs, sediments and supply chains — provenance science explained.
Dr. Elias Brandt ·
Carbon and nitrogen isotope ratios let ecologists read what reef animals actually ate — and whether kelp carbon reached them. Here's how the method works.
