Hubbard Glacier
__NOTOC__ Hubbard Glacier (Lingít: ''Sít' Tlein'') is a glacier located in Wrangell–St. Elias National Park and Preserve in eastern Alaska and Kluane National Park and Reserve in Yukon, Canada, and named after Gardiner Hubbard. Geography The longest source for Hubbard Glacier originates from its snout and is located at about , approximately west of Mount Walsh with an elevation around . A shorter tributary glacier begins at the easternmost summit on the Mount Logan ridge at about at about . Before it reaches the sea, Hubbard is joined by the Valerie Glacier to the west, which, through forward surges of its own ice, has contributed to the advance of the ice flow that experts believe will eventually dam the Russell Fjord from Disenchantment Bay waters. The Hubbard Glacier ice margin has continued to advance for about a century. In May 1986, the Hubbard Glacier surged forward, blocking the outlet of Russell Fjord and creating Russell Lake. All that summer, the new lake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakutat City And Borough, Alaska
The City and Borough of Yakutat (, ; Tlingit: ''Yaakwdáat''; russian: Якутат) is a borough in the U.S. state of Alaska and the name of a former city within it. The name in Tlingit is ''Yaakwdáat'' (meaning "the place where canoes rest"). It derives from an Eyak name, ''diyaʼqudaʼt'', and was influenced by the Tlingit word ''yaakw'' ("canoe, boat"). The borough covers an area about six times the size of the U.S. state of Rhode Island, making it one of the largest counties (or county equivalents) in the United States. As of the 2020 census, the population was 662, same number as previous census. As of 2010, it was Alaska's least populous borough or census area, and the ninth-least populous county nationwide. The population had declined from 680 in 2000. The Borough of Yakutat was incorporated as a non-unified Home Rule Borough on September 22, 1992. Yakutat was previously a city in the Skagway–Yakutat–Angoon Census Area (afterwards renamed as the Skagw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lake Outburst Flood
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. Definition A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glac ...

Glaciers Of Alaska
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ice Calving
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier.Essentials of Geology, 3rd edition, Stephen Marshak It is a form of ice ablation or ice disruption. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an iceberg, but may also be a growler, bergy bit, or a crevasse wall breakaway.Glossary of Glacier Terms Ellin Beltz, 2006. Retrieved July 2009. Calving of glaciers is often accompanied by a loud cracking or booming sound before blocks of ice up to high break loose and crash into the water. The entry of the ice into the water causes large, and often hazardous waves. The waves formed in locations like |

Norwegian Sun
''Norwegian Sun'' is a ''Sun'' class cruise ship operated by Norwegian Cruise Line. She entered service in 2001 in a dual christening ceremony at the Port of Miami with '' Norwegian Star''. She was constructed at the Lloyd Werft shipyard in Bremerhaven, Germany. Vessel class ''Norwegian Sun'' is the third and final ship of this design. She was preceded by '' Norwegian Sky'' (entered service in 1999, relaunched as ''Pride of Aloha'' in 2004); and ''Costa Victoria'' of Costa Cruises (entered service in 1996).

The Hubbard Glacier In Disenchantment Bay, Alaska In June Of 2022
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Iceberg
An iceberg is a piece of freshwater ice more than 15 m long that has broken off a glacier or an ice shelf and is floating freely in open (salt) water. Smaller chunks of floating glacially-derived ice are called "growlers" or "bergy bits". The sinking of the ''Titanic'' in 1912 led to the formation of the International Ice Patrol in 1914. Much of an iceberg is below the surface, which led to the expression "tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard. Icebergs vary considerably in size and shape. Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs. The largest iceberg in recent history (2000), named B-15, measured nearly 300 km × 40 km. The largest iceberg on record was an Antarctic tabular iceberg of over [] sighted west of Scott Island, in the South Pacific Ocean, by the USS Glacier ...
