Chamcook Lake
Chamcook Lake is a lake of Saint Andrews Parish, New Brunswick, Canada. It is located just north of the Passamaquoddy Bay which is part of the Bay of Fundy, near the border with Maine, United States. The town of Chamcook, New Brunswick lies on the eastern bank of the lake and Chamcook Mountain is nearby. The lake has been notable within New England and Canada for its fishing. Etymology Chamcook comes from the Passamaquoddy word ''K'tchumcook'' which, according to William Francis Ganong, has many meanings but none are certain. Geography Chamcook Lake is approximately from Passamaquoddy Bay. The lake is connected by road to St. Stephen, New Brunswick. A Canadian Pacific Railway freight service station has been located at Chamcook Lake. The lake is situated at above sea level, and has a maximum depth of . The Chamcook River which feeds the Chamcook Lake rises from the cone shaped hill range of Mt. Chamcook. The Chamkcook harbour, a wet dock, lies is to the eastern side of the p ...

Saint Andrews Parish, New Brunswick
Saint Andrews Parish is a civil parish in Charlotte County, New Brunswick, Canada, located east of St. Stephen. The parish lost political significance after county municipalities were abolished in 1966. Local governance in the area is now provided by two entities: the town of Saint Andrews, which includes Navy Island and the Chamcook Local Service District, which includes Ministers Island. The LSD assesses for fire, police, zoning, emergency measures and animal control services. The taxing authority is 513.00 Chamcook. Both the town and the LSD are members of the Southwest New Brunswick Service Commission (SNBSC). Statistics Canada divides the area into Saint Andrews, Parish, and Saint Andrews, Town. Origin of name Historian William F. Ganong notes the use of ''St. Andrews Point'' in the Owen Journal of 1770 but considered the name to date back to French times. Five of the original six mainland parishes of Charlotte County used names of major saints recognised by the Church ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feldspar
Feldspars are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight. Feldspars crystalize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Compositions The feldspar group of minerals consists of tectosilicates, silicate minerals in which silicon ions are linked by shared oxygen ions to form a three-dimensional network. Compositions of major elements in common feldspars can be expressed in terms of three endmembers: * potassium feldspar (K-spar) ...

Potamogeton Gramineus
''Potamogeton gramineus'' is a species of aquatic plant known by the common name various-leaved pondweed, variableleaf pondweed, grass-leaved pondweed or grassy pondweed, native to the northern hemisphere where it grows in shallow, clean water. Description This is an aquatic perennial growing from a creeping rhizome that anchors in wet substrate. It produces thin, cylindrical, heavily branching stems usually less than a metre in length. The submerged leaves are sessile, relatively narrow, typically 40–90 mm long and 5–12 mm wide along the main stem but smaller on the side branches. They are translucent and pale green with a white midrib, and finely toothed. Floating leaves are more oval in shape, 20–70 mm long by 7–34 mm wide, and borne on long petioles. The inflorescence is a short spike of many flowers arising from the water on a stout peduncle. This species readily hybridizes with many other species of ''Potamogeton''. Hybrids have been recorded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagittaria Montevidensis
''Sagittaria montevidensis'' is a species of flowering plant in the water-plantain family Alismataceae. Common names include giant arrowhead and California arrowhead. Description ''Sagittaria montevidensis'' is a robust, stemless, rhizomatous, aquatic plant.

Isoetes Echinospora
''Isoetes echinospora'', also known as spiny quillwort, spiny-spored quillwort or spring quillwort is a species of quillwort in the Isoetaceae family, and is the most abundant species in Canada. It can be found in shallow aquatic environments from Labrador and Newfoundland to Alaska, and south to Pennsylvania, Wisconsin, Colorado, and California. In Germany it is found in only two locations: the Feldsee and Lake Titisee, both in the High Black Forest.Information Board at the Feldsee. Recorded on 26 Aug 2015. It bears 10–30 green to yellow leaves and a two-lobed corm. The velum covers one to three quarters of the sporangium A sporangium (; from Late Latin, ) is an enclosure in which spores are formed.

Lymnaea Stagnalis
''Lymnaea stagnalis'', better known as the great pond snail, is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. The great pond snail is a model organism to study parasitology, neurology, embryonal development and genetic regulation. ''Limnaea stagnalis'' var. ''baltica'' Lindström, 1868: synonym of ''Lymnaea stagnalis'' (Linnaeus, 1758) Distribution The distribution of this species is holarctic, mainly the temperate zones of Northern America, Europe and Asia. The snail can be found in many ponds, lakes and very slow-moving rivers with a rich underwater vegetation. The northernmost populations exist in northern Norway, and in Central Europe, it inhabits even montane ecosystems at 1700 meters above sea level. In the ''Saprobiensystem'' used in Germany to judge the quality of freshwater biotopes, the species has a value of 1.9 and indicates a biotope with a water quality class II, the second-highest.

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plate ...
