Selected lake depths (surface and bottom water) and streams were analyzed for boron geochemistry. Boron stable isotope values in these waters span the range of +&amp;nbsp;12.3&amp;permil; to +&amp;nbsp;51.4&amp;permil;, which corresponds to the variations from glacier meltwater streams to the hypolimnion of a highly evaporated hypersaline lake. The data demonstrate that the major sources of B to the aquatic system are via terrestrial chemical weathering of aluminosilicates within the stream channels, and a marine source, either currently being introduced by marine-derived aerosols or in the form of ancient seawater. Lakes Fryxell, Hoare, and upper waters of Lake Joyce, which experience more terrestrial influence of aluminosilicate chemical weathering via glacial meltwater streams, display a mixture of these two major sources, while the source of B in the bottom waters of Lake Joyce appears to be primarily of marine origin. Lakes Bonney and Vanda and the Blood Falls brine have a marine-like source whose δ&lt;sup style=&quot;font-size: 0.75em; line-height: 0;&quot;&gt;11&lt;/sup&gt;B values have become more positive by mineral precipitation and/or adsorption. Don Juan Pond displays a terrestrial aluminosilicate influence of a marine-like source. These hypersaline lake waters from Antarctica are similar in δ&lt;sup style=&quot;font-size: 0.75em; line-height: 0;&quot;&gt;11&lt;/sup&gt;B to other hypersaline lake waters globally, suggesting that similar processes control their B geochemistry.&lt;/p&gt;&lt;div&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;</style></abstract><section><style face="normal" font="default" size="100%">152</style></section></record></records></xml>
