The 10 Worst River Basins Contributing to Ocean Plastics

The 10 Worst River Basins Contributing to Ocean Plastics | Geography Education | Scoop.it

"[A new paper], published in the journal Environmental Science and Technology, calculates that rivers contribute between 410,000 and 4 million tonnes a year to oceanic plastic debris, with 88 to 95% [of that total] coming from only 10. Those rivers are the Yangtze, Yellow, Hai He, Pearl, Amur and Mekong in east Asia, the Indus and Ganges Delta in south Asia, and the Niger and Nile in Africa."

Seth Dixon's insight:

Of river-based plastic pollution, these 10 rivers are responsible for 88%-95% of all the plastic gyrating in the world's oceans.  Improvement in these key places could make a world of difference in improving marine ecosystems (NOTE: the map came from this alternative article on the same subject).

Iceland's Glacial Melt and Geothermal Activity

Iceland's Glacial Melt and Geothermal Activity | Geography Education | Scoop.it

Glacial melting and flooding occurs every year by the Skafta River in Iceland. As the water travels down towards the North Atlantic Ocean, incredible patterns are created on the hillsides. Rising lava, steam vents, or newly opened hot springs can all cause this rapid ice melt, leading to a sizable release of water that picks up sediment as it flows down from the glaciers.

The Tidal Waves of the Qiantang River

The Tidal Waves of the Qiantang River | Geography Education | Scoop.it
For hundreds of years, on the eighth month of the lunar calendar, people have gathered along the shores of China’s Qiantang River at the head of Hangzhou Bay to witness the waves of its famous bore tide. Higher-than-normal high tides push into the harbor, funneling into the river, causing a broad wave that can reach up to 30 feet high. If the waves surge over the banks, spectators can be swept up, pushed along walkways or down embankments. Below, I’ve gathered images from the past few years of the Qiantang bore tides.
Seth Dixon's insight:

This is an amazing set of images, where a cultural phenomenon is wrapped up in observing the pulsating physical geography of the river.  Usually the tidal bore is impressive (but not dangerous--see video here), but occasionally it can be incredibly violent (see this 2015 video).

On occasion, we are reminded of how utterly captivating and gorgeous nature is, its visual poetry surrounds us. It just takes a step back, a shift in perspective, to realize how amazing the constructs of this planet are; it’s a beautiful constant balance between order and entropy.

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake | Geography Education | Scoop.it

"It's difficult to comprehend the ridiculous amounts of water that have fallen in such a short time in a state that, until recently, had been in the grip of a historic drought. But one place to start would be to look at reservoir levels in the state. In the past 30 days, Texas reservoirs have gone from being 73 percent full to 82 percent full, according to data maintained by the Texas Water Development board. All told, about 8 million acre-feet of water have flowed into the state's reservoirs."

Seth Dixon's insight:

Just how much of water is 8 million acre-feet?  It's almost impossible for most people to visualize that, but this series of graphics is designed to put the scale of the recent flooding in Texas into perspective (and yes, I love that Rhode Island is almost a unit of measurement).

Bang Kachao: Bangkok’s Green Lung

Bang Kachao: Bangkok’s Green Lung | Geography Education | Scoop.it

"In the heart of Thailand’s most populous city, an oasis stands out from the urban landscape like a great “green lung.” That’s the nickname given to Bang Kachao—a lush protected area that has escaped the dense development seen elsewhere in Bangkok.  The city is built on the alluvial plain of the Chao Phraya River. Toward the southern end, near the Gulf of Thailand, is an old meander that never quite formed an oxbow lake. That meander traces the boundary of Bang Kachao, which TIME magazine once called the 'best urban oasis' in Asia.  According to a travel story in The New York Times, Bang Kachao is gaining popularity among tourists lured by bike tours, a floating farmers’ market, and the relaxed atmosphere."

Danielle Lip's curator insight, April 14, 2015 12:32 PM

These pictures of the heart of Thailand is very interesting and intriguing because the viewer can get a view of what the city Bang Kachao really looks from a arial view. The researcher call Bang Kachao the green lung because the area looks like a lung as well as the meander that formed an oxbow lake. Every country. city has different landmarks that make the location their own such as Michigan whose borders look like a mitten. Bang Kachao is becoming larger and growing more and more in population such as tourists, farmers and bike tourers. This location has a relaxed atmosphere and the Landsat image gives it justice, showing its actual size as a city based on its location near the Chao Phraya River towards the Gulf of Thailand which allows for access to the gulf and other different trading advantages.

Savannah Rains's curator insight, May 27, 2015 1:51 AM

This scoop shows an example of built environmental space. The highly urban and crowded Thailand has little green space. So why is this massive green park looking landmass there? Its a strictly environmental section of land to help water flow into the ocean. The people call it the "green lung" because its plants give off oxygen and provide a contrast from its urban sprawl. This article shows the importance that should be placed on having more strictly environmental places in big cities. 

Chris Costa's curator insight, November 9, 2015 2:06 PM

It's interesting to see the mixture of natural and manmade landscapes in this image. Humans have an enormous influence on the world around us- we have moved entire rivers for our own purposes, reshaped entire regions. In China, we have literally made it rain. Therefore, it's nice to see remnants of the rich environments that used to cover the urban sprawls of many of the world's largest cities, like Central Park in New York. Bang Kachao in Bangkok is another example of this, a reminder of the richness of the region before it was overwhelmed by the urban development that has characterized Bangkok over the previous century. The oasis serves as a valuable tourist attraction, as Westerners come to enjoy the bike trails and small farming community within Thailand's green lung. Leave it to hipsters to travel halfway across the globe just to enjoy nature within the confines of one of the world's largest cities.

El Sire Reserve in Peru is a river that has been monitored over the last 28 years. Every time I watch this short 6 second clip, I learn something different about how this river has changed. On the bottom of the screen, just past half way, the river just takes a huge short cut and cuts over and connects to a different part of the same river. This happens on the whole river too. there are 8 or 9 huge bends and curves in the river but by the end in 2012 there are only about 3 to 4 bends and curves. For some reason the water is taking short cuts and just leaving the spaces where the water used to run through and leaving it dry.

All rivers move. Those that have a wide, flat basin meander most. Those meanders can be even more dramatic than in this image, snaking 10's of kilometres sideways over time. Combine this action with geological upheaval and it gets even more interesting. Check out images of the Murray River in Australia from space.
Matthew DiLuglio's curator insight, December 6, 2013 11:34 AM

Lol... the first words that went through my head were h--- (heck) yeah.  David Bowie... sung by an astronaut... okay, back to Geography. I thought that the rivers reminded me of something I thought of during the talk in class about lava rock being changed into other kinds of rocks over time, and cycling around.  I thought on a larger scale, about this universe, and I have read before that people are studying different areas of space-time fabrics, trying to find origins of the Universe, and answers to other existential questions.  I suppose that if one could trace patterns of rivers, and if one could trace patterns of rocks, to find where they came from, and why/how they came where they came, then by examining the (assumedly tattered and marked) fabrics of space and time, people would be able to determine origins of everything from the beginning of what existed before all universes, and also the origins of life forms.  I enjoyed the movie Prometheus, which was directed by Sir Ridley Scott, and I had to say that I thought that the messages found on rocks in caves, as a catalyst that lead the cast to go visit an alien world that had something to do with human origins, could be very literally taken.  If there are clues in rocks, why wouldn't there be other clues, possibly in celluar components of life forms, or space and time?  Applying the idea of studying rocks and rivers and other physical geographical pursuits to the idea of applying it on a gigantic scale greatly appeals to me.  I believe that humans will find some answers that way, but I hadn't directly realized just that until we mentioned some stuff about physical geography, and glacial forces carrying and spreading out rocks, and deposits and erosion.  After all, the Milky Way has origins, so why believe that we came from the Milky Way, rather than beyond?

Mekong Delta fights losing battle against salt water

Vietnam's rice region is facing the worst drought to date. Over half a million people have been affected, and the country could lose one million tons of its staple food.Leaders of six countries along the Mekong River met in China to discuss the relief measures.
Seth Dixon's insight:

Economic progress for some often entails job loss and environmental degradation for others.  As dams upstream are slowing the flow of the Mekong River, the low-lying delta that is a rich agricultural region is facing the ocean water that is moving further inland.  The once isolated and remote Mekong is experiencing some impacts of globalization.

The Geography of New Orleans

The Geography of New Orleans | Geography Education | Scoop.it
Geographers make a distinction between site and situation as they consider the underlying foundation of a place. Few cities represent such a wide chasm between these two aspects as does New Orleans. The situation, or the answer to why does a place exist, was imperative. The Mississippi River was a major artery for the North American continent. As first the Europeans and then the Americans assumed control of the area, a port was essential at the mouth of this river. But the site, the response to where a city is placed, continues to confound. Few environments were or are more inhospitable to human habitation. Poor soil, disease, floods, and hurricanes are constant threats that have plagued the city for over three centuries. But the why trumped the where and hence the paradox of New Orleans persists.
Seth Dixon's insight:

New Orleans is the classic example to use to explain the difference between site and situation...lousy site, incredible situation.  These maps are a nice introduction to the city.

Actually a very good video.  My one quibble is with the introduction, when the narrator talks about mountain streams "carving" their gorges.  The puzzle of how small streams could possibly carve out deep bedrock canyons is an ongoing research problem, and is difficult to resolve from a gradualistic perspective.

Jason Schneider's curator insight, January 27, 2015 12:15 AM

So pretty much, the water controls rivers rather than particles controlling the river. Also, it appears that the motion and strength of the water causes rivers to bend and form in different curves. I'd like to think of it as a ball bouncing from side to side and every time it touches the border land of a river, it expands to the opposite side. However, when the water flow is hitting the side of a river, the opposite side is not getting any force from the water flow. In that case, the side that is not getting hit by the water flow slowly moves to the side that is being by the water flow causing river curves.

Louisiana Loses Its Boot

Louisiana Loses Its Boot | Geography Education | Scoop.it
The boot-shaped state isn’t shaped like that anymore. So, we revised its iconic outline to reflect the truth about a sin…
Seth Dixon's insight:

Maps shape how we think about places.  In mapping, we can reveal or conceal important pieces of information but sometimes the phenomena don't fit the easy binaries.  In most places there is land, a coastline and then water (simple enough), but Louisiana's coastline is much more complicated with large regions being more of a coastal zone than a neat line.  That accounts for some of the inaccuracies mapping Louisiana, but some lies are so convenient, that many people want the fiction to continue.  It is comforting to think about places as permanent, and admitting that it isn't is acknowledging that there might be a problem.  As stated in this article, "the boot is at best an inaccurate approximation of Louisiana’s true shape and, at worst, an irresponsible lie."  To explore the issue yourself, this gorgeous interactive map pulls together some high quality source materials on a wide range of issues to look at this environmental issues of this region in a holistic manner.

(North America topic 7)
Just like geography and history textbooks become obsolete the day they're published (thanks to Professors Dixon and Bonin for the phrase!), the same can be said for maps and icons.

This article uses the example of Louisiana's state highway signs, which show the outline of the state... well, according to data from the 1930s. While an updated sign isn't as pretty, it does bring about the truth that the landscape is changing, and on a larger scale this is true for the entire world, especially with influence from development and climate change.
However, I can relate to the other side of the argument too. Tossing the old LA symbol would toss a historical reminder of what once was. The same can be said for New Hampshire's Old Man of the Mountain road signs and license plates. I'd hate to see the profile removed, especially since what is symbolizes still lives on in the hearts of many residents and visitors, including myself.
