- Der Taku-Gletscher ist ein 58 km langer Gletscher in den Boundary Ranges östlich von Juneau in Alaska. Er ist der größte Auslassgletscher des Juneau Icefield. (de)
- Le glacier Taku est un glacier côtier de l'Alaska du Sud-Est, juste au sud-est de la ville de Juneau. Le glacier fut d'abord nommé glacier Schultze en 1883 puis glacier Foster en 1890, mais Taku, le nom que les amérindiens Tlingit locaux avaient pour le glacier, s'imposa. Il se trouve dans la chaîne Côtière (Coast Mountains) et prend naissance dans le champ de glace Juneau dont il est le plus grand glacier et l'un glaciers côtiers les plus méridionaux de l'hémisphère nord. Le glacier, qui converge vers la Taku River dans la baie Taku (Taku Inlet), a plusieurs fois progressé, dans son histoire, jusqu'à ce qu'il bloque la rivière, créant un lac, suivi par une dramatique rupture du barrage de glace. La plus récente de ces avancées du glacier date de 1750. Le glacier a avancé de 7,5 kilomètres depuis 1890. C'est le seul glacier qui avance des 20 plus importants glaciers provenant du Juneau Icefield. Si cette avance continue, il bloquera de nouveau la rivière. Depuis 1946, le glacier est observé annuellement par le Juneau Icefield Research Program, qui a noté une avance du glacier depuis 1988 de 17 mètres par an. Cette avance est provoquée par un équilibre positif de la masse du glacier (plus de glace qui se forme que de glace qui fond). Jusqu'à présent, le glacier, du fait de cet équilibre de masse positif, semblait insensible au réchauffement climatique qui touche tous les autres glaciers environnants. La récente inversion de cet équilibre entre 1989 et 2005 n'est pas encore suffisante pour arrêter cette avance mais est sans doute le premier signe que le glacier ne progressera plus dans l'avenir.

- Taku Glacier (Lingít: T'aaḵú Ḵwáan Sít'i) is a tidewater glacier located in Taku Inlet in the U.S. state of Alaska, just southeast of the city of Juneau. Recognized as the deepest and thickest alpine temperate glacier known in the world, the Taku Glacier is measured at 4,845 feet (1,477 m) thick. It is about 58 kilometres (36 mi) long, and is largely within the Tongass National Forest. The glacier was originally named Schultze Glacier in 1883 and the Foster Glacier in 1890, but Taku, the name the local Tlingit natives had for the glacier, eventually stuck. It is nestled in the Coast Mountains and originates in the Juneau Icefield. It is the largest glacier in the icefield and one of the southernmost tidewater glaciers of the northern hemisphere. The glacier, which converges with the Taku River at Taku Inlet, has a history of advancing until it blocks the river, creating a lake, followed by a dramatic break of the ice dam. The most recent of these advances occurred in 1750. The glacier has advanced 7.75 kilometres (4.82 mi) since 1890, and as of June 29, 2012 is 1.26 kilometres (0.78 mi) from Taku Point. It is the only advancing glacier of the 20 major glaciers of the Juneau Icefield. If the advance continues it will again block the river, but this appears unlikely at present. Since 1946, the glacier has been monitored by the Juneau Icefield Research Program, which has documented its rate of advance since 1988 at 17 metres (56 ft) a year. The advance is due to a positive mass balance; that is, more snow accumulates than snow and ice melt. Until 1948 the glacier had a calving front; since then the terminus has been grounded. Due to the positive mass balance and the fact that it was no longer losing mass to icebergs, Taku Glacier has become insensitive to the warming that has impacted all other glaciers of the icefield. This has driven its advance. The recent negative mass balance 1989-2005 is not large enough yet to stop the advance, but it is the first sign that the glacier's advance may not take it to Taku Point. Taku Glacier is the namesake of the Alaska Marine Highway System ferry M/V Taku. Taku Glacier was reported to be in retreat as of 2019. (en)
- Il ghiacciaio Taku si trova nello Stato dell'Alaska, poco a sud-est della città di Juneau.È un ghiacciaio artico in avanzamento, ampio 428 km² con una lunghezza di 92 km, che termina nel fiume omonimo. In origine si chiamava Schultze (nel 1883) e Foster (nel 1890), poi però ha prevalso il nome Taku, datogli dai nativi Tlingit. (it)
- O glaciar Taku é um glaciar de maré situado a sudeste da cidade de Juneau, no Alasca. O glaciar foi inicialmente (1883) baptizado glaciar Schultze e em 1890 glaciar Foster, mas seria a designação dada ao glaciar pelos nativos tlingit, Taku, que acabaria tornando-se a designação mais comum. Flui desde o campo de gelo Juneau, sendo o maior dos glaciares de descarga deste campo de gelo e um dos glaciares de maré mais meridionais do hemisfério norte. O glaciar Taku, que converge com o , apresenta um comportamento que se repete ao longo do tempo: avança até bloquear o rio, criando assim um lago, ao que se segue a rotura dramática da parede de gelo. O mais recente destes avanços ocorreu em 1750. Desde 1890 o glaciar Taku avançou 7,5 km. É o único glaciar em avanço, entre os vinte maiores glaciares com origem no campo de gelo Juneau. A continuação do avanço provocará mais uma vez o bloqueio do rio Taku, mas actualmente é improvável que tal aconteça. Este glaciar tem sido monitorizado anualmente desde 1946, estando documentado um avanço médio de 17 metros por ano desde 1988. O avanço é devido a um balanço de massa positivo, isto é, a acumulação de neve é maior que a ablação por fusão de gelo e neve. Até 1948 o glaciar Taku apresentava uma zona terminal da qual se desprendiam icebergues. Entre 1989 e 2005 o balanço de massa foi negativo, mas insuficiente para parar o seu avanço, pelo menos para já. (pt)
