Abstract Excerpt:
Estuaries are unique water systems that are under the influence of various natural and anthropogenic factors. They are of significant interest to specialists of various disciplines of Earth sciences, and in the last half century many countries have conducted detailed studies of them, including basic aspects of estuarine ecosystem ecology (Elliott and Hemingway 2002; McLusky and Elliott 2004; McLusky and Wolanski 2011; Day et al. 2012; Wolanski and Elliott 2015).
