LeConte Glacier
LeConte Glacier is a and glacier in the U.S. state of Alaska. It flows southwest to the head of LeConte Bay. It was named in 1887 by U.S. Navy Lieutenant-Commander Charles M. Thomas in honor of a California geologist Joseph LeConte. According to John Muir's book about indigenous peoples of the area, the Tlingits called it “Huti ic which he claimed derived from a mythical bird that produced sounds of thunder when it flapped its wings. Since its discovery, the glacier has retreated nearly , although it is considered to be in a stable position toda The glacier is known for its "shooter" icebergs which calve off underneath the water (LeConte Bay is deep) and shoot out of the water due to their buoyancy. In 2019 acoustic observations found that the submarine part of LeConte Glacier melts significantly faster than previously predicted by scientific theory. Being south of the 57th parallel north, LeConte Glacier is the southernmost tidewater glacier of the Northern Hemisphere. T ...

LeConte Bay
LeConte Bay is an 810-foot-deep (247 m), six-mile-long (10 km) bay in the southeastern region of the U.S. state of Alaska, located east of Frederick Sound. The bay was named in 1887 for Joseph LeConte, then professor of geology at the University of California. According to John Muir, the local Tlingit name for the bay is Hutli, the mythical thunderbird. LeConte Bay is a very steep-sided fjord that is home to a seal rookery and the terminus of LeConte Glacier LeConte Glacier is a and glacier in the U.S. state of Alaska.

57th Parallel North
The 57th parallel north is a circle of latitude that is 57 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. At this latitude the sun is visible for 17 hours, 53 minutes during the summer solstice and 6 hours, 43 minutes during the winter solstice. During the summer solstice, nighttime does not get beyond nautical twilight, a condition which lasts throughout the month of June. Everyday of the month of April can view both astronomical dawn and dusk. The maximum altitude of the Sun is > 18.00º in October and > 11.00º in November. The only capital city on the 57th parallel north is Riga.

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Currently, ...

M/V LeConte
MV ''LeConte'' ( ) is a feeder vessel for the Alaska Marine Highway System, built in Sturgeon Bay, Wisconsin in 1973 and commissioned in 1974 by Alaska's ferry system. ''LeConte'' is the older sister ship to M/V ''Aurora'', and both serve as feeder vessels that pick up passengers in small communities such as Hoonah and take them to larger regional communities (this process is colloquially known as the "milk run"). The ''LeConte'' primarily serves the northern portion of the Alaskan Panhandle in between Sitka and Juneau, but also occasionally ventures into Southeast Alaska as well. In a highly controversial and political change, however, the ''LeConte'' was turned into a day boat operated exclusively out of Juneau. This change cut service to the community of Pelican and to the hub of Sitka — home of the Southeast Alaska Regional Health Center, a hospital that solely serves the Native Alaskan community, the primary demographic of the ''Lecontes ports of call. In the summer o ...

Alaska Marine Highway System
The Alaska Marine Highway (AMH) or the Alaska Marine Highway System (AMHS) is a ferry service operated by the U.S. state of Alaska. It has its headquarters in Ketchikan, Alaska. The Alaska Marine Highway System operates along the south-central coast of the state, the eastern Aleutian Islands and the Inside Passage of Alaska and British Columbia, Canada. Ferries serve communities in Southeast Alaska that have no road access, and the vessels can transport people, freight, and vehicles. AMHS's of routes go as far south as Bellingham, Washington, in the contiguous United States and as far west as Unalaska/Dutch Harbor, with a total of 32 terminals throughout Alaska, British Columbia, and Washington. It is part of the National Highway System and receives federal highway funding. It is also the only method of transportation of vehicles between the state and the contiguous United States, not requiring international customs and immigration. The Alaska Marine Highway System is a rare ...

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

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...

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 ...
