Juliana A. Ivar do Sul has a PhD degree in Oceanography from the Federal University of Pernambuco, Brazil, and studies marine microplastics for 15 years. She has been involved in international research collaborations and has taken part in a number of interdisciplinary research projects in Europe, on oceanic islands in the South Atlantic, and Antarctica. As recognition of her research, she was invited in 2015 to contribute as the Plastic expert member within the Anthropocene Working Group. Her recent studies have focused particularly on the longevity of microplastics, and their potential as markers of the Anthropocene epoch. Ivar do Sul currently works at the Leibniz Institute for Baltic Sea Research in Rostock, Germany, which is leading the GSSP candidature of the Baltic Sea to indicate the onset of the Anthropocene.
