She has conducted survey work for marine spatial planning projects in the Caribbean and provided research support as a graduate fellow for the Sustainable Fisheries Group. "Most meteorites contain at least some metallic iron-nickel and so will be at least somewhat magnetic and set off metal detectors," Rubin wrote in an email. Mineral magnets are not attracted by all meteorites; only meteorites that contain a high concentration of iron (such as iron-rich meteorites) will attract them. Material that didnt fit through either sieve is wider than 1.5 mm, and probably doesnt contain micrometeorites.
