Fjords are long, narrow sea inlets with steep sides that stretch along the coasts of western Norway and Chile.
Fjord derives its name from the Norse word fjordr, meaning to travel through or pass. Scoresby Sund in Greenland is considered to be the world’s longest fjord while Norway’s Sognefjord comes in second.
Definition
Fjords are long, narrow sea inlets formed by glacier activity with steep sides or cliffs and usually deep waters that create steep sides or cliffs, located all around the world but most prevalent in Scandinavia, southwestern United States, Canada, South America and Antarctica. Fjords may also serve as bays.
Fjords are formed by glaciers moving under their own weight and wearing away the landscape they travel through. Once they reach the sea, these glaciers deposit debris and sediments onto it and this creates U-shaped valleys which are both deep and narrow.
Fjords take multiple glacial cycles to fully form, growing or shrinking with each cycle. Fjords act as a natural trap that records environmental changes over time such as climate change; modern palaeoceanographic studies make use of them.
Fjord derives its name from a Norwegian phrase meaning “where one fares.” Initially used to refer to waterways, this term became part of Norwegian vernacular usage during early settlement by people hailing from Southern Europe where fjords are common.
Norway is home to some of the world’s most beloved fjords and considered among its most stunning travel destinations. National Geographic and Chicago Tribune both listed them among their top travel destinations worldwide while western Norway’s UNESCO World Heritage Site status recognizes their beauty. Attracting millions of tourists each year, these natural wonders attract millions more every year while contributing significantly to Norway’s economy through fertile lands for growing vegetables and fruit and providing fresh and delicious fish from its waters that is enjoyed worldwide.
Origin
Norway’s fjords boast an intriguing name. Their name derives from the Norwegian word fjordr, meaning “place where one passes.” It shares this origin with both fare and ferry.
In the last glacial period, glaciers created mountain valleys by carving through rivers or stream flows. When this ice melted away, its contents flowed back into the sea via streams, raising sea levels while filling valleys cut by glaciers – leaving behind long narrow sea inlets known as fjords that still exist today.
Because fjords are formed from mountains, their depth can often surpass that of surrounding seas. According to geoscience professor Jason Briner of the University of Buffalo, glacial erosion plays an integral part in this phenomenon – as when glaciers cut through bedrock they wear away at it until valleys can fill with water and become deeper than surrounding seas.
Geologists tend to think fjords originated as glaciers receded from coastlines, leaving behind long valleys in the rock. Although some researchers subscribe to this theory, others suggest they were caused by continental drift and uplift, with mountains around fjords rising with rising sea levels.
Fjords are breathtaking natural features. Not only are they visually captivating, but their presence also serves a significant purpose for shipping and tourism; Skagway wouldn’t be such an active cruise ship port if not for them!
Characteristics
Fjords are long, narrow bodies of water formed when glaciers eroded deep canyons into mountain beds that were then filled with sea water when melting glaciers reached them. Surrounded by steep cliffs that often continue below the water surface and far inland from their coasts. Fjords are most prevalent in the Northern Hemisphere – an area most heavily covered with glaciers during Ice Ages – including Norway, North America from Puget Sound to Alaska, and New Zealand’s west and southwest coastlines.
Fjords, being situated in regions once glaciated, display breathtaking examples of both marine and terrestrial natural beauty. Their stunning steep cliffs create a spectacular setting against which the tranquil waters below can rest; their rugged shorelines often serve as home for diverse ecosystems that support both plants and animals alike.
Fjord is not simply the name for any body of water; rather it refers to any valleys and canyons formed by glaciers as well as mountain ranges, lakes, rivers or other landforms carved by them.
Geologist Eric Briner describes fjords as “geologic sculptures.” Their formation depends on factors like rock type, currents and wind conditions.
Fjord environments often foster unique phytoplankton communities due to nutrient-rich meltwater from glaciers or ice sheets; diatom concentrations play an essential role in food chains; this has led to research being done on fjords within ecology and biology fields.
Environment
Fjords are distinguished by their distinct environment. Surrounded by mountains that rise several thousand meters from water level, fjords feature rich ecosystems including mountains extending several kilometers inland; during the Ice Ages glaciers eroded valleys along their coastal edges into canyons filled with seawater; their interior waters tend to be cooler than surrounding ocean waters due to increased nutrients making fjords ideal environments for phytoplankton growth.
However, these coastal geomorphological marine features are under serious threat. Fjords face pressure from various sources such as mining, shipping and oil and gas exploration as well as climate change induced intrusion of warm waters incursions, glacier retreat, sea-ice loss and rising sea levels – which all compromise their ecosystems and threaten their integrity.
Long-term riverine nutrients may also be disrupted by reduced meltwater output due to global warming and changing hydrological conditions (Bianchi et al., 2020). River-fjord dynamics could have significant ramifications on organic matter accumulation, mineralization and uptake by microbes in fjord environments.
Most fjords can be found in the northern hemisphere, which was covered with glaciers during past Ice Ages. Fjords can be found along the coasts of Europe and Greenland in Norway as well as along North America’s west coast from Puget Sound to Alaska as well as on South America’s west and south-western coastlines such as Chile; they may even exist south of the equator where there were once glaciated mountain ranges such as New Zealand or Chile.
Tourism
Geirangerfjord, a UNESCO World Heritage site and Norway’s most well-known fjord, draws thousands of cruise passengers annually. Due to this increased visitation, overtourism is an increasing concern among local residents; various strategies have been put in place in order to limit visitor numbers and avoid having any negative effects on its fragile fjord ecosystems.
Tourists are becoming more mindful of their impactful travel on the environment, with many seeking eco-label certification to minimize any negative repercussions of their trips. Furthermore, more tourists are willing to pay more for sustainable tourism products.
As such, tourism businesses have more and more opportunities to market fjords as eco-friendly destinations in countries where climate change is an ongoing problem.
Norway is home to numerous bodies of water known as “fjords,” including Oslofjord (which is actually a rift valley) and Lake Mjosa near Lillehammer. However, fjord is most often associated with glaciated landscapes in Western Norway.
Recent research of tourists visiting Norwegian fjord areas revealed that tourists from the Netherlands had more positive price perceptions, net incomes and activity intentions compared to visitors from any other nationality. Furthermore, their overall satisfaction levels were highest and activities that contributed to environmental sustainability were of particular interest; suggesting that developing these markets would benefit Norwegian tourism significantly.
As part of an effort to survey visitors to fjord regions, questionnaires were distributed at six locations – Bergen airport and ferry terminals in Hella and Lavik were among them – between 25 May and 15 September 2016 across 153 survey days; surveys were administered both in English and German using nonprobability sampling designs to reduce sampling bias.
