Cape Kolka
Cape Kolka (, ) is a cape on the Baltic Sea, near the entry to Gulf of Riga, on the Livonian coast, in the Courland Peninsula of Latvia. The cape is surrounded by the Irbe Strait (Irbes šaurums) which serves as the natural border with Estonia. Cape Kolka represents the north-western limit of the Gulf of Riga. East of the cape is the island of Ruhnu (Estonia) that lies in the middle of the Gulf. Near the cape is Kolka Lighthouse and the village of Kolka. There is a line of picturesque old Livonian settlements along the Baltic Sea shore, including Vaide, Saunags, Pitrags, Košrags and Sīkrags, all included into the culturally protected territory "Livonian Coast". Coastal dune ecology Situated on the north-western tip of the Courland Peninsula, Cape Kolka lies within Slītere National Park on the Baltic Sea coast of Latvia. The cape is fringed by a belt of seacoast wooded dunes, where boreal dry Scots pine (''Pinus sylvestris'') forms the dominant tree cover on nutrient ...

Cape (geography)
In geography, a cape is a headland, peninsula or promontory extending into a body of water, usually a sea. A cape usually represents a marked change in trend of the Coast, coastline, often making them important landmarks in sea navigation. This also makes them prone to natural forms of erosion, mainly tidal actions, resulting in a relatively short geological lifespan. Formation Capes can be formed by Glacier, glaciers, Volcano, volcanoes, and changes in sea level. Erosion plays a large role in each of these methods of formation. Coastal erosion by waves and currents can create capes by wearing away softer rock and leaving behind harder rock formations. Movements of the Earth's crust can uplift land, forming capes. For example, the Cape of Good Hope was formed by tectonic forces. Volcanic eruptions can create capes by depositing lava that solidifies into new landforms. Cape Verde, (also known as Cabo Verde) is an example of a volcanic cape. Glaciers can carve out capes by erod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Košrags
Košrags ( Livonian: ''Kuoštrõg'') is a small village in Kolka Parish, Talsi Municipality, Latvia. It sits on the shore of the Irbe Strait of the Baltic Sea The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by the countries of Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden, and the North European Plain, North and Central European Plain regions. It is the .... It is one of twelve Livonian villages on ' ( Livonian Coast). The "Kukiņi" homestead located in Košrags was first mentioned in 1680 chronicles. Košrags is one of the newest of Liv villages, formed in the 17th century. By 1770 four old farms operated in Košrags (Kine-Dīķi, Kūkiņi, Tilmači and Žoki). Two tenant-farmer habitations existed in 1896, and another seven habitations after 1905. The houses were built densely along two roads: * an old littoral road connecting all 16 Livonian fishermen villages at that time; * the fishermen's road leading from the littora ...

Landforms Of Latvia
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Livonian People
The Livonians, or Livs, are a Balto-Finnic people indigenous to the Livonian Coast, in northwestern Latvia. Livonians historically spoke Livonian, a Uralic language closely related to Estonian and Finnish. It was believed that the last person to have learned and spoken Livonian as a mother tongue, Grizelda Kristiņa, died in 2013. In 2020, however, it was reported that newborn Kuldi Medne had become the only living person who speaks Livonian as their first language. As of 2010, there were approximately 30 people who had learned it as a second language. Historical, social and economic factors, together with an ethnically dispersed population, have resulted in the decline of Livonian identity, with only a small group surviving in the 21st century. In 2011, there were 250 people who claimed Livonian ethnicity in Latvia. History Prehistory The exact date of migration of Livonians to the region has been disputed. "The Livonians claim to have inhabited their present homeland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground-penetrating Radar
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. This nondestructive method uses electromagnetic radiation in the microwave band ( UHF/ VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks. GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter and antenna emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strandplain
A strand plain or strandplain is a broad belt of sand along a shoreline with a surface exhibiting well-defined parallel or semi-parallel sand ridges separated by shallow swales. A strand plain differs from a barrier island in that it lacks either the lagoons or tidal marshes that separate a barrier island from the shoreline to which the strand plain is directly attached. Also, the tidal channels and inlets which cut through barrier islands are absent. Strand plains typically are created by the redistribution by waves and longshore currents of coarse sediment on either side of a river mouth. Thus, they are part of one type of wave-dominated delta.McCubbin, D.G., 1982, ''Barrier-island and strand-plain facies.'' in P.A. Scholle, and D. Spearing, eds., pp. 247–279., Sandstone Depositional Environments: Memoir no. 31, Tulsa, Oklahoma, American Association of Petroleum Geologists, Tulsa, Oklahoma.Fitzgerald, D.M., W.J. Cleary, I.V.

Progradation
In sedimentary geology and geomorphology, the term progradation refers to the growth of a river delta farther out into the sea over time. This occurs when the volume of incoming sediment is greater than the volume of the delta that is lost through subsidence, sea-level rise, or erosion. Progradation can be caused by: * Periods of sea-level fall which result in marine regression. This can occur during major continental glaciations within ice ages, be caused by changes in the rates of seafloor spreading that affects the volume of the ocean basins, or tectonic effects on the regional mantle density structure that can change the geoid elevation. * Extremely high sediment input, such as by the Huang He (Yellow River) in China China, officially the People's Republic of China (PRC), is a country in East Asia. With population of China, a population exceeding 1.4 billion, it is the list of countries by population (United Nations), second-most populous country after ..., whi ...

Sediment Transport
Sediment transport is the movement of solid particles (sediment), typically due to a combination of gravity acting on the sediment, and the movement of the fluid in which the sediment is entrained. Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay; the fluid is air, water, or ice; and the force of gravity acts to move the particles along the sloping surface on which they are resting. Sediment transport due to fluid motion occurs in rivers, oceans, lakes, seas, and other bodies of water due to current (fluid), currents and tides. Transport is also caused by glaciers as they flow, and on terrestrial surfaces under the influence of wind. Sediment transport due only to gravity can occur on sloping surfaces in general, including hillslopes, escarpment, scarps, cliffs, and the continental shelf—continental slope boundary. Sediment transport is important in the fields of sedimentary geology, geomorphology, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scots Pine
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US), Baltic pine, or European red pine is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old growing in Estonia which stands at . The lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. The bark is thick, flaky and orange-red when young to scaly and gray-brown in maturity, sometimes retaining the former on the upper portion. The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of foliage. The shoots are light ...

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called ''Erg (landform), ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the wiktionary:stoss, stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of Outwash plain, glacial outwash ...
