Element variability in lacustrine systems of Terra Nova Bay (Antarctica) and concentration evolution in surface waters
Major, minor and trace elements were determined in freshwater of lacustrine systems in Terra Nova Bay, along Victoria Land coast, Antarctica, as well as in algae and mosses. The samples were collected during some of the sampling campaigns between 2007 and 2011 (and the one of 2002) within the framew...
