norway coastline paradox

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. That's absurd--Canada is 3.9 million square miles, while Norway is only 148,728 square miles. It's not exactly a paradox- it's sometimes called the coastline problem, which is a better name, I think. 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'. 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. Norway attempted to stay neutral in World War II (like all other Nordic Countries) and remained so until the 9th of April 1940, when Germany invaded both Denmark and Norway as part of Operation Weserübung. About twenty thousand kilometres of coasts, corresponding to 20% face serious impacts in 2004. Nearly 300 million people inhabit these deltas. That's because it's impossible to accurately measure coastline. .hide-if-no-js { This results from the fractal-like properties of coastlines. 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). Norway: D = 1.52 Questions: The four countries listed above are shown below, rotated to make them less easy to recognize. 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 -- … The CIA World FactBook indicates 25 148 km. What if I had measured the coastline by zooming even more in until I come to the level of atoms ? 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). So what would be determined as the base line for legal bounderies mesurment? Time limit is exhausted. There are a lot more details as you see! 04:56 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. A straight line along Norway's sea borders (the coastal perimeter) is 2,650 kilometers (1,650 mi) long. So my coastline should be drawn again by taking into account the new details that come up. Coastline Market is an online platform connecting harvesters with retailers. 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.  ×  Spend a week exploring beautiful Norway on this Fjord and Coastline tour. five Result? 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.

The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. The coastline of Norway is formed along the Skagerrak, North Sea, Norwegian Sea, and Barents Sea. At my first try of digitizing the coastline, I used straight lines which were about ~100km long. 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. Undermining of artificial sea defences as a result of chronic sediment shortage, Salman et al. How long is the coastline of Australia?

A Map and Street View experiment visualising the actual and predicted global sea level rise caused by the climate crisis. The other part is the methodology used to measure coastlines. Most of the impact zones (15,100 km) are actively retreating, some of them in spite of coastal protection works (2,900 km). One estimate is that it's about 12,500 km long. 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). Travel off the beaten track to the Fjord Coast and get a taste of authentic coastal life. The Coastline Paradox Explained - Duration: ... Fjord Norway Recommended for you. 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? The first external link on the page seems to be the source of the article's problems. The study includes the European deltas of Danube, Ebro, Po, Rhine, and Rhone. 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 … [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. timeout The coastline paradox states that a coastline does not have a well-defined … That’s one points.  =  The Coastline Paradox Explained ...

That's not (really) how the coastline paradox works. Much more details and an enormous more work for us if we want to measure the coastline! Destruction of natural sea defences (usually a dune system) as a result of storm events, which may result in flooding of the hinterland. For instance, whatever the zoom level you’re using, you should see little to no difference with the Belgian coast (almost a straight line – SI close to 1). Norway does have plains and forested areas, mostly to the southeast and the northernmost part. By changing the zoom level, I … You cannot go further west in Norway.
