Aplicação de métodos isotópicos e numéricos em paleoceanografia com base em foraminíferos planctônicos

Abstract

APPLICATION OF ISOTOPIC AND NUMERICAL METHODS IN PALEOCEANOGRAPHY BASED ON PLANKTONIC FORAMINIFERA. Paleoceanography represents a multidisciplinary approach that combines efforts to reconstruct the history of oceans and the effects of interactions between changes in the composition, circulation and productivity in large water masses and climate changes. Paleoceanography is a discipline that tries to learn from the past in order to predict future climate changes. In this context, planktonic foraminifera, which are abundant and widely distributed in the oceans, store in their shells past water mass conditions. Age, temperature and productivity are among the parameters that can be inferred by studying the association and the composition of the shells of these organisms. This work is aimed to present the application of isotopic methods and numerical paleoceanography using planktonic foraminifera as a tool. Citation: Zerfass G. de S. dos A., Sánchez F. J.
