Lågskär
Lågskär ( Swedish for "low skerry") is a small island within the Åland archipelago of Finland. It belongs to the municipality of Lemland. It is situated about south of Mariehamn in the Baltic's Sea of Åland. The main island of Lågskär measures in area. Rock stacks, sea cliffs and rocky shores are found along the coastline of the island. As a breeding ground for waterfowl, Lågskär has the status of an Important Bird Area (IBA) and is frequented by ornithologists who use the Lågskär Lighthouse buildings during their stay. In the past, several vessels have sunk off the coast. History The earliest habitation on the island was linked to a cairn and a wooden beacon that existed on the island during the 1600s and 1700s. In the 1840s, when the first lighthouse was constructed to replace the beacon, there were 20–30 inhabitants comprising the families of the lighthouse keepers. In addition to rearing livestock, fishing, and hunting wildlife, the families ran a school for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lågskär Lighthouse
Lågskär Lighthouse is an automated lighthouse located on the north side of Lågskär, one of Finland's Åland in the Sea of Åland of the Baltic Sea, Baltic. It is the only striking feature on Lågskär on the generally uninhabited island. The lighthouse is designed as a concrete tower, square in shape, with a lantern and gallery. The lens has a focal plane of with white light flashing every 12 seconds. The light has run on wind power since 1986. While the ground floor of the site is open, the tower itself is closed. It is maintained by the Finnish Maritime Administration, and the buildings are often let out to ornithologists studying on the island. History A wooden lighthouse was built in 1840 on northwestern tip of the island and was rebuilt in 1859 as a masonry structure. During World War I, it was destroyed by Russian Army, Russian bombardment. A temporary structure was erected thereafter. The present lighthouse was constructed in 1920.

Sea Of Ã…land
The Åland Sea (or the Sea of Åland; , ) is a waterway in the southern Gulf of Bothnia, between Åland and Sweden. It connects the Bothnian Sea with the Baltic Proper, Baltic Sea proper. The western part of the basin is in Swedish territorial waters while the eastern part is in Finnish territorial waters. The Åland Sea has two sub-basins. The main basin is the Åland Sea proper, also called the northern Åland Sea basin. In the south, there is the smaller Lågskär Deep, also called the Lågskär Basin or the southern Åland Sea basin. The narrowest part on the northern edge of the basin is named the Southern Quark or South Kvarken (, ). The trench running on the bottom of the Sea of Åland contains the second-deepest spot of the Baltic Sea, at a depth of 301 meters, which is second only to Landsort Deep. The mean depth of Åland Sea is 75 m, area 5,477 km2 and its volume is 411 km3. The Archipelago Sea and the Åland Sea regulate water exchange between Gulf of Bothni ...

Finnish Submarine Vesihiisi
''Vesihiisi'' was a Finnish 500-tonne that was constructed in the early 1930s. The vessel served in the Finnish Navy during the second World War. The name ''Vesihiisi'' refers to a mythological Finnish sea creature similar to a Siren. German design ''Iku-Turso'', ''Vesihiisi'', ''Vetehinen'' While preparing the design of the , the Germans also prepared a design for a seagoing submarine for the Finnish Navy. Three submarines were built to this design, and like ''Saukko'', they were fitted for mine-laying, the mines being supplied by the Germans. Being designed for use against Soviet bases (never very far from the Finnish bases), the radius of action was not of prime importance to this design, and only 20 tons of fuel oil were carried (as opposed to the 67 tons carried by the German Type VIIa based on this design. Combat operations Winter War ''Vesihiisi'' was alerted with ''Vesikko'' to the Hanko region on 30 November 1939 as several Soviet surface combatants were headed t ...

Söderarm
Söderarm is the name of a deactivated Swedish lighthouse station and its surrounding small archipelago in the west part of the Sea of Åland. The light station is located on the island of Thorskär. This area, together with the tiny island of Tjärven north of Söderarm, marks the entrance for the shipping route leading to the ports of Kapellskär, Norrtälje, and also the north entrance to Stockholm. The area has been heavily fortified by the Swedish military and coastal artillery, and many traces of military activity from the years during the second world war are still visible. On the island of Manskär, for example, a large military radar mast stood for many years. It was demolished in 2010. In 2002, the coastal artillery was formally liquidated at Söderarm, but still some islands are forbidden for the public to visit. The Swedish Maritime Administration has confirmed that many Russian mines dating from the First World War may still lie on the sea bottom east of the light sta ...

Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

Sill (geology)
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A sill is a ''concordant intrusive sheet'', meaning that it does not cut across preexisting rock beds. Stacking of sills builds a sill complex. and a large magma chamber at high magma flux. In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Formation Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nassau-class Battleship
The class was a group of four dreadnought battleships built for the German (Imperial Navy) in the early 1900s. The ship class, class comprised , the lead ship, , , and . All four ships were laid down in mid-1907, and completed by late 1910. They were Germany's first dreadnought class, and though commonly perceived as having been built in response to the British , their design traces its origin to 1903; they were in fact a response to ''Dreadnought''s predecessors of the . The s adopted a main battery of twelve guns in six twin-gun turrets in an unusual hexagonal arrangement. Unlike many other dreadnoughts, the -class ships retained triple-expansion steam engines instead of more powerful steam turbines. After entering service, the -class ships served as II Division, I Battle Squadron of the High Seas Fleet for the duration of their careers. From 1910 to 1914, the ships participated in the normal peacetime routine of the German fleet, including various squadron exercises, traini ...
