Sturgeon Bay (Ontario)
Sturgeon Bay is an arm of Green Bay extending southeastward approximately 10 miles into the Door Peninsula at the city of Sturgeon Bay, located approximately halfway up the Door Peninsula. The bay is connected to Lake Michigan by the Sturgeon Bay Ship Canal. The Potawatomi name for Sturgeon Bay is "Na-ma-we-qui-tong". Origin The bay seems to represent the pre-glacial path of the Menominee River, with the valley deepened by glacial carving and then submerged into rising lakewaters. Bridges Three bridges cross the bay, including the historic Sturgeon Bay Bridge, and the recently finished Oregon Street Bridge. Fish Sturgeon Bay and Little Sturgeon (just to the south of Sturgeon Bay) are considered biodiversity hotspots because they support a large number of different fish species. Researchers collected viral hemorrhagic septicemia viruses from 184 different fish from 2003 to 2017. Two were found from 2007–2010 infecting smallmouth bass within Sturgeon Bay. Each of t ...

Door County, Wisconsin
Door County is the easternmost county in the U.S. state of Wisconsin. As of the 2020 census, the population was 30,066. Its county seat is Sturgeon Bay. It is named after the strait between the Door Peninsula and Washington Island. The dangerous passage, known as Death's Door, contains shipwrecks and was known to Native Americans and early French explorers. The county was created in 1851 and organized in 1861. Nicknamed the “Cape Cod of the Midwest,” Door County is a popular Upper Midwest vacation destination. It is also home to a small Walloon population. History Native Americans and French Porte des Morts legend Door County's name came from Porte des Morts ("Death's Door"), the passage between the tip of Door Peninsula and Washington Island. The name "Death's Door" came from Native American tales, heard by early French explorers and published in greatly embellished form by Hjalmar Holand, which described a failed raid by the Ho-Chunk (Winnebago) tribe to capture ...

Viral Hemorrhagic Septicemia
Viral hemorrhagic septicemia (VHS) is a deadly infectious fish disease caused by Viral hemorrhagic septicemia virus. It afflicts over 50 species of freshwater and marine fish in several parts of the Northern Hemisphere. Different strains of the virus occur in different regions, and affect different species. There are no signs that the disease affects human health. VHS is also known as Egtved disease, and the virus as Egtved virus. Historically, VHS was associated mostly with freshwater salmonids in western Europe, documented as a pathogenic disease among cultured salmonids since the 1950s. Today it is still a major concern for many fish farms in Europe and is therefore being watched closely by the European Community Reference Laboratory for Fish Diseases. It was first discovered in the US in 1988 among salmon returning from the Pacific in Washington state. This North American genotype was identified as a distinct, more marine-stable strain than the European genotype. VHS has sinc ...

Bays Of Wisconsin
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129. Bays were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potawatomi State Park
Potawatomi State Park is a Wisconsin state park northwest of the city of Sturgeon Bay, Wisconsin in the Town of Nasewaupee. It is located in Door County along Sturgeon Bay, a bay within the bay of Green Bay. Potawatomi State Park was established in 1928. History The federal government began a quarry operation at what is now Potawatomi State Park in 1834. Two years later, the Menominee ceded their claim to the Door Peninsula, including the area which became Potawatomi State Park, to the United States in the 1831 Treaty of Washington. Following the treaty the lands surrounding what is now the park were opened to settlement, which meant that the more decentralized Potawatomi in the area were divested of their land without compensation.Chapter oThe Migrations: 1835–1845in ''Place of refuge for all time'' by James A. Clifton, University of Ottawa Press, 1975, pages 65, 73, and 86–87 (pages 2, 10, and 23–24 of the pdf) In 1837 the federal government enacted a 1,000 acre fe ...

Resourcesat-2
Resourcesat-2 is a follow on mission to Resourcesat-1 and the eighteenth Indian remote sensing satellite built by Indian Space Research Organisation (ISRO). The new satellite provides the same services as the original Resourcesat-1, but was also designed to "provide data with enhanced multispectral and spatial coverage". Compared to Resourcesat-1, LISS-4 multispectral swath has been enhanced from 23 km to 70 km based on user needs. Suitable changes including miniaturization in payload electronics have been incorporated in Resourcesat-2. Launch Resourcesat-2 along with YouthSat and X-Sat (Singapore) was launched by the Polar Satellite Launch Vehicle PSLV-C16 on 20 April 2011, at 04:42 UTC.

Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull to ...

Hexagenia
''Hexagenia'' is a genus of mayfly in the family Ephemeridae, the common burrower mayflies. Species These eight species belong to the genus ''Hexagenia'': * '' Hexagenia albivitta'' (Walker, 1853) * '' Hexagenia atrocaudata'' McDunnough, 1924 * '' Hexagenia bilineata'' (Say, 1824) * '' Hexagenia callineura'' Banks, 1914 * '' Hexagenia limbata'' (Serville, 1829) * '' Hexagenia mexicana'' Eaton, 1885 * '' Hexagenia orlando'' Traver, 1931 * ''Hexagenia rigida'' McDunnough, 1924 Data sources: i = ITIS, c = Catalogue of Life, g = GBIF, b = Bugguide.net General information ''Hexagenia'' are commonly referred to as burrower mayflies as they create u-shaped tunnels in the aquatic substrate where they reside. This shape allows them to draw in water from the surrounding areas by undulating their body near the mouth of the tunnel. ''Hexagenia'' feed upon microscopic organisms suspended in the water column and thus draw in all the food and oxygen they require. Therefore, these burrowing may ...

Hexagenia Bilineata
''Hexagenia bilineata'' is a species of mayfly in the family Ephemeridae. It is native to North America where it is found in the Upper Mississippi Valley. Sometimes adults of this mayfly are so abundant as to cause a nuisance because of their enormous numbers. The larvae are aquatic and burrow in mud and the adult insects have brief lives. Description When the adults are ready to emerge, the mayfly nymphs (larvae) swim to the surface of the water during the night. Their skin splits and winged subimagos struggle free, usually in less than a minute, and fly to nearby trees to rest. They are a dull gray color and have short, coarse legs, bristly cerci and cloudy, grayish wings. Some eight to eighteen hours later, these subimagos moult into mature adults (imagos). These are altogether more delicate in appearance than the subimagos; the wings are transparent, the legs are longer and more slender, the cerci lack bristles, the eyes are larger and the body is patterned in brown and cre ...

Hexagenia Limbata
''Hexagenia limbata'', the giant mayfly, is a species of mayfly in the family Ephemeridae. It is native to North America where it is distributed widely near lakes and slow-moving rivers. The larvae, known as nymphs, are aquatic and burrow in mud and the adult insects have brief lives. They are often referred to as fish flies around the Great Lakes as they tend to cause the areas around water to smell like rotten fish. Description The mature adult stage of ''Hexagenia limbata'' can be as much as long. The females tend to be slightly larger than the males but have smaller eyes. The forewings are long and membranous while the hind wings are much smaller and have dark margins. The tip of the abdomen bears two long cerci or tails. When the insect is at rest, the wings are folded vertically above the back. The color and body markings are somewhat variable but this insect is usually some shade of yellow, pale brown or white. Distribution and habitat ''Hexagenia limbata'' is the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Hotspot
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hotspots support up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sturgeon Bay, Wisconsin
Sturgeon Bay is a city in and the county seat of Door County, Wisconsin, United States. The population was 9,646 at the 2020 Census. The city is well-known regionally for being the largest city of the Door Peninsula, after which the county is named. History The area was originally inhabited by the Ho-Chunk and Menominee. The town is known in the Menominee language as ''Namāēw-Wīhkit'', or "bay of the sturgeon". The Menominee ceded this territory to the United States in the 1831 Treaty of Washington. After that, the area was available for white settlement. The community was first recorded as Graham in 1855 but, in 1857, the state legislature organized it as the town of Ottumba. Subsequently, the name was reverted to Graham and, in 1860, a petition was submitted to the county board to change the community's name to that of the adjacent bay. A company of volunteer firefighters was established in 1869. In 1874, Sturgeon Bay was incorporated as a village. It became a city in 1883 ...
