Research
Fernández was considered "one of Europe's leading experts" on the relationship between carbon dioxide emissions and ocean acidity;[7] she also investigated the ocean depth at which such changes in pH occur.[8] Through her work, Ríos argued that observations of increased acidity in the Atlantic Ocean is best explained by changes in the accumulation of carbon dioxide produced by human activity rather than from natural sources.[9][8]
