A origem da salinidade no Continente Antártico

Abstract

A Antártica é o mais perfeito laboratório natural do planeta para estudos de mudanças ambientais. Partindo dessa premissa, este estudo teve como objetivo realizar uma revisão sobre a origem dos sais presentes no continente antártico, sendo pormenorizado as principais formas e fontes salinas que ocorrem. Na literatura, este tema é de grande discussão, sendo relatado que a origem dos sais pode ser devido à precipitação atmosférica, intemperismo de rochas, origem marinha (spray salino), sulfatos biologicamente produzidos ou atividade hidrotermal. De maneira geral, a presente revisão permitiu inferir diversas origens dos sais solúveis em água nos solos da Antártica. Perto da costa, influências marinhas são dominantes, encobrindo quaisquer contribuições do intemperismo das rochas. Mas para o interior, a influência do intemperismo é mais evidente, ao passo que a influência de circulação atmosférica superior torna-se importante também. Ressalta-se também, a importância da contribuição continental no aporte de sais nos períodos glaciais.
