3D Printed Products Made in the Adirondacks! All European coastal states are to some extent affected by coastal erosion. This results from the fractal-like properties of coastlines. Basically the problem is defining what is meant by a coastline, which must, inherently, be arbitrary, and could produce a wildly different result depending on what standard you pick. About twenty thousand kilometres of coasts, corresponding to 20% face serious impacts in 2004. The key here is the scale! 0 items. }, Approximately 20% of the deltas show accelerated subsidence, while only 12% show eustatic sea-level rise as the predominant effect. Decreased accretion of fluvial sediment resulting from upstream siltation of artificial impoundments and consumptive losses of runoff from irrigation are the primary determinants of ESLR in nearly 70% of the deltas. The CIA World FactBook indicates 25 148 km. The more I zoom in, the more precise I can be. 418 Views. What is known is that the CIA World FactBook numbers and scales used vary for all countries, thus making comparing the numbers worthless. setTimeout( That's absurd--Canada is 3.9 million square miles, while Norway is only 148,728 square miles. Let’s make the exercise again but draw the line more precisely: Now we get 4 167.6 km … still far way from the 25 148 km. Norway is located in northern Europe on the Scandinavian peninsular. The methodology we use is visibly not the best one. ... See Whales, the Northern Lights, and Norway’s Pristine Beauty | Short Film Showcase. Featured. Like Norway (and perhaps maybe even more so), much of Chiles coast is made of up highly glaciated land (fiords, islands, etc). At my first try of digitizing the coastline, I used straight lines which were about ~100km long. June 2020 | By Timo Aho, Pekka Niittyvirta, in collaboration with Google Arts and Culture . Time limit is exhausted. Coastline Paradox: The coastline paradox says that the coastline of a piece of land does not have a finite length. This is one difference. The landscape of the Fjord Coast has been shaped through thousands of years. Most of the impact zones (15,100 km) are actively retreating, some of them in spite of coastal protection works (2,900 km). De tekst is beschikbaar onder de licentie Creative Commons Naamsvermelding/Gelijk delen, er kunnen aanvullende voorwaarden van toepassing zijn.Zie de gebruiksvoorwaarden voor meer informatie. Proove you're not a robot * ... Also, keep the main naval assets outside the Norwegian coast on convoy-strikes to do as much damage as possible to any reinforcements. [1] [2] It was first observed by Lewis Fry Richardson.More concretely, the length of the coastline depends on the method used to measure it. Norway's coastline is one of the longest in the world, with the length recalculated in 2011 to account for complicated features like islets and fjords. Over the past 50 years, the population living in European coastal municipalities has more than doubled to reach 70 millions inhabitants in 2001 and the total value of economic assets located within 500 meters from the coastline has multiplied to an estimated 500-1000 billion Euros in 2000 (1).  =  The World Resources Institute measures the coastlines of the countries INCLUDING overseas islands. According to the CIA World FactBook, the ten countries with the longest coastline are the following (when we take into account Greenland and Antarctica of course): But, if we base our analysis on the data coming from the World Resources Institute, we get the following list: This list IS VERY different from the other list. Four key recommendations have been proposed to make coastal erosion problems and risks in Europe manageable (1): The references below are cited in full in a separate map 'References'. timeout In addition, another 4,700 km have become artificially stabilised (1). The Coastline Paradox Explained. Coastal erosion results in three different types of impacts (or risks): Coastal erosion is influenced by several human factors, including (1): From an assessment of contemporary effective sea-level rise (ESLR) for a sample of 40 deltas distributed worldwide it was concluded that direct anthropogenic effects determine ESLR in the majority of deltas studied, with a relatively less important role for eustatic sea-level rise. That’s correct! Just a little precision: The “B” in the name “Benoit B. Mandelbrot”, stands for “Benoit B. Mandelbrot”, which “B” stands for “Benoit B. Mandelbrot”, which “B” stands for “Benoit B. Mandelbrot”, … funny isn’t it . No-one knows how long Norway's coastline is! The length of any coastline or irregular shape depends on the unit of measurement used to measure it. The country shares its coastline with the Atlantic Ocean on the east, the Pacific Ocean on the west, the Arctic Ocean to the north of Alaska, and the Gulf of Mexico towards the southwest. The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. Travel off the beaten track to the Fjord Coast and get a taste of authentic coastal life. What if I had measured the coastline by zooming even more in until I come to the level of atoms ? In addition, another 4,700 km have become artificially stabilised (1). Use the relative roughness of each coastline to identify the country, and enter its name in the box below the image: [ ] [ ] [ ] [ ] The coastline of Norway would then be infinite! It is dominated by the Scandinavian mountains, which separates Norway from its neighboring country Sweden. Undermining of artificial sea defences as a result of chronic sediment shortage, Salman et al. The Coastline Paradox Explained - Duration: ... Fjord Norway Recommended for you. Unlike the Hanseatic traders who have dominated our economy for centuries the Dutch are content to trade without meddling in local businesses or breaking the laws of the land. If I had taken a third source, I would have gotten a third different result…, The two lists are different because the CIA World Factbook takes the countries in their different subparts: Greenland is detached from Denmark, all the overseas territories of France are measured apart from the mainland, etc. Statistical Self-Similarity and Fractional Dimension, Tracking Sydney Ferries in real time with OpenSource GIS tools. For the contemporary baseline, ESLR estimates range from 0.5 to 12.5 mm per year (4). So what would be determined as the base line for legal bounderies mesurment? It begins with an explanation of the coastline paradox and other, similar … You cannot go further west in Norway. The answer to the question “How long are coastlines?”  is: undefined! The coastline paradox, the idea that the perimeter of a land mass is infinite, appears to arise from certain assumptions in the article and incomplete data. Along the coast there are many fjords, islands, and bays, resulting in a low-resolution coastline of over 25,000 kilometers (16,000 mi). Coastline Lengths - world statistics and charts as map, diagram and table. 418 Views. The deltas in this study represent all major climate zones, levels of population density, and degrees of economic development. These production levels are driven by a strong and growing demand for farmed fish, and has a stated political goal of increased growth by a factor of 5 by 2050 in Norway alone. Interesting subject for a thesis . The United States of America is one of the largest countries of the world, and is composed of 50 states, fiver major territories, and several minor territories. (2004). })(120000); The length of the coast for the countries of the world Coastline Market is an online platform connecting harvesters with retailers. Time limit is exhausted. According to this study, serious challenges to human occupancy of deltaic regions worldwide are conveyed by other factors than the climate change–sea-level rise (4). The risk of coastal flooding due to the undermining of coastal dunes and sea defences potentially affects several thousands of square kilometres and millions of people. Overview. Coastline Paradox . I would say it basically depends on the level of “straightness” of your coastline often represented by the Sinuosity Index in the case of a river (http://en.wikipedia.org/wiki/Sinuosity). This results from the fractal curve-like properties of coastlines, i.e., the fact that a coastline typically has a fractal dimension (which in fact makes the notion of length inapplicable). 04:56 The first external link on the page seems to be the source of the article's problems. Save my name, email, and website in this browser for the next time I comment. The cost of coastal erosion (coastline protection against the risk of erosion and flooding) has been estimated to average 5,400 million euro per year between 1990 and 2020 (2). The country has a total coastline of around 19,924 km, and 23 states of the country have a coastline to call their own. 04:56 Lewis Fry Richardson was the first recorded observer of this paradox. That’s one points. Timber has always been a major export of the Norwegian economy and trade ships from the Low Countries have become an increasingly common sight along the Norwegian coastline. Your email address will not be published. If we examine the "official" numbers listed here, Norway has 20X more coastline than land boundaries, while Chile has approximately the same coastline as land boundaries -- … Norway: D = 1.52 Questions: The four countries listed above are shown below, rotated to make them less easy to recognize. For any delta, ESLR is a net rate, defined by the combination of eustatic sea-level rise, the natural gross rate of fluvial sediment deposition and subsidence, and accelerated subsidence due to groundwater and hydrocarbon extraction. Coastline paradox The coastline paradox5 is the counterintuitive observation that the coastline of a landmass does not have a well-de ned length. If the coastline of Britain is measured using units 100 km long, the total length of the coastline is approximately 2,800 km long whereas if … Australia's coastline is very straight and direct. Featured product Lake George Refrigerator Magnet Regular price $12.00 Sale price $12.00 Regular price. The World Resources Institute uses the SAME scale and methodology for measuring all countries coastlines, making for a MUCH more accurate comparison. World Resources Institute measures the coastlines of the countries INCLUDING overseas islands Featured. As you can see on the picture, if the unit of measure becomes smaller, so larger become the total coastline! However if you sort the list by "World Resources Institute" instead you'll see very different numbers, with Norway dropping to 7. Ok, I was not so precise as I draw the line. The Coastline Paradox Explained. Sale Sold out. The Coastline Paradox observes that the measure of the coastline of a landmass keeps getting bigger the smaller the unit used to measure it is, as seen here.. What I don’t understand is, why doesn’t the measurement approaches a number as the unit approaches zero? Norway: D = 1.52 Questions: The four countries listed above are shown below, rotated to make them less easy to recognize. Severe coastal erosion will be a growing problem as rising sea levels and a reduction in sea ice allow higher waves and storm surges to reach the shore. The other part is the methodology used to measure coastlines. Result? Extrapolating contemporary rates of ESLR through 2050 reveals that 8.7 million people and 28,000 km2 of deltaic area in the sample set of deltas could suffer from enhanced inundation and increased coastal erosion (4). 03:14 Greenpeace holds a historic performance with pianist Ludovico Einaudi on the Arctic Ocean (English) 571 Views. But this is only a part of the story …. At 30-meter (98 ft) linear intercepts, this length increases to 83,281 kilometers (51,748 mi) (see the coastline paradox).
