Lake Untersee
Lake Untersee (german: Untersee, "Lower Lake") is the largest surface freshwater lake in the interior of the Gruber Mountains of central Queen Maud Land in East Antarctica. It is situated to the southwest of the Schirmacher Oasis. The lake is approximately long and wide, with a surface area of , and a maximum depth of . The lake is permanently covered with ice and is partly bounded by glacier ice. Lake Untersee is an unusual lake, with pH between 9.8 and 12.1, dissolved oxygen at 150 percent supersaturation, and very low primary production in the water column. Despite the high oxygen supersaturation in most of the lake, there is a small sub-basin at the southern end that is anoxic and its sediments may have a higher methane concentration than those of any other known lake on Earth. Much of the primary production is in microbial communities that grow on the floor of the lake as stromatolites. The water temperature varies between and and the ice cover on the lake is ...

Untersee (Lake Constance)
The Untersee (German for ''Lower Lake''), also known as Lower Lake Constance, is the smaller of the two lakes that together form Lake Constance and forms part of the boundary between Switzerland and Germany. Geography The Lower Lake Constance measures and is situated about lower than the Obersee. The Romans called it ''Lacus Acronius''. In the Middle Ages, the Upper Lake was called ''Bodamicus Lacus'', or ''Bodensee'' in German. At some point in time, this term began to include the Lower Lake, and a new term "Upper Lake" (in German: '' Obersee''), was introduced for the larger lake. The main tributaries are the Seerhein and Radolfzeller Aach. The landscape surrounding the Untersee is very diverse. The Untersee contains two islands: Reichenau and Werd (near the transition to the High Rhine). In the northeast is found the peninsula Bodanrück; in the northwest, the Hegau lowlands with the peninsula Mettnau; in the west, the peninsula Höri, with a mountain called S ...

Lake Constance
Lake Constance (german: Bodensee, ) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Lake Rhine (''Seerhein''). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria, the Swiss cantons of St. Gallen, Thurgau, and Schaffhausen, and the Austrian state of Vorarlberg. The actual location of the border is disputed. The Alpine Rhine forms in its original course the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton of Schaffhausen) the German-Swiss border as far as to the city of Basel. The most populous towns on the Upper Lake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
