During its advance, the RIS was grounded along the southern Victoria Land coast, completely blocking the mouths of several of the McMurdo Dry Valleys (MDVs). Several authors have proposed that very large paleolakes, proglacial to the RIS, existed in many of the MDVs. Studies of these large paleolakes have been key in the interpretation of the regional landscape, climate, hydrology, and glacier and ice sheet movements. By far the most studied of these large paleolakes is Glacial Lake Washburn (GLW) in Taylor Valley. Here, we present a comprehensive review of literature related to GLW, focusing on the waters supplying the paleolake, signatures of the paleolake itself, and signatures of past glacial movements that controlled the spatial extent of GLW. We find that while a valley-wide proglacial lake likely did exist in Taylor Valley during the early stages of the Ross Sea I glaciation, during later stages two isolated lakes occupied the eastern and western sections of the valley, confined by an expansion of local alpine glaciers. Lake levels above ~140 m asl were confined to western Taylor Valley, and major lake level changes were likely driven by RIS movements, with climate variables playing a more minor role. These results may have major implications for our understanding of the MDVs and the RIS during the Ross Sea I glaciation.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Maciek K.

Numerous studies have attempted to reconstruct the evolution of LB because of its sensitivity to climatic variations and the lack of reliable millennial-scale continental records of climate in this region of Antarctica. However, these studies are limited by the availability of accurate lacustrine chronologies. Here, we attempt to better constrain the chronology of LB and thus, the evolution of past regional climate by estimating water residence times based on He, Ne and Ar concentrations and isotopic ratios in both WLB and ELB.&lt;/p&gt;&lt;p id=&quot;sp0015&quot; style=&quot;font-size: 16px; margin-top: 0px; margin-bottom: 9px; font-family: Arial, Helvetica, 'Lucida Sans Unicode', 'Microsoft Sans Serif', 'Segoe UI Symbol', STIXGeneral, 'Cambria Math', 'Arial Unicode MS', sans-serif; word-spacing: -0.15ex; color: rgb(46, 46, 46); line-height: 23.6800003051758px;&quot;&gt;&lt;sup style=&quot;font-size: 0.75em; line-height: 0;&quot;&gt;3&lt;/sup&gt;He and&amp;nbsp;&lt;sup style=&quot;font-size: 0.75em; line-height: 0;&quot;&gt;4&lt;/sup&gt;He excesses up to two and three orders of magnitude and 35&amp;ndash;150 times the atmospheric values are observed for WLB and ELB samples, respectively.

He isotopic ratios suggest that He excesses are predominantly crustal (&amp;gt;93%) in origin with small mantle contributions (&amp;lt;7%).

These results support the presence of remnant water from proglacial lakes that existed during Marine Isotope Stage 7 (160&amp;ndash;240&amp;nbsp;kyrs) in WLB, in agreement with previous studies. In comparison,&amp;nbsp;&lt;sup style=&quot;font-size: 0.75em; line-height: 0;&quot;&gt;4&lt;/sup&gt;He ages in ELB are much younger (&amp;lt;27&amp;nbsp;kyrs BP) and display a complex evolutionary history that is very different from WLB.&amp;nbsp;&lt;sup style=&quot;font-size: 0.75em; line-height: 0;&quot;&gt;4&lt;/sup&gt;He ages also suggest that the ELB ice cover formed significantly earlier (&amp;sim;1.5&amp;nbsp;kyrs BP) than previously reported. The timing of these hydrologic changes in ELB appears to correspond to regional and global climatic events that are recorded in both the Taylor Dome ice-core record as well as in other Dry Valley Lakes.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Peter T.
