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).

The Depths of the Unseen Ocean

The Depths of the Unseen Ocean | Geography Education | Scoop.it

"The depths below the ocean’s surface comprise a staggering 95 percent of the Earth’s living space, and much of it is unexplored by humans. To put into perspective just how deep the oceans go, this XKCD comic, (hi-res image).  Most of the ocean doesn’t even see sunlight. Even scientists aren’t familiar with everything that’s down there."

Seth Dixon's insight:

XKCD is a comic strip that deals with many intellectual issues, but it can also be a wealth of quality scientific information.  This infographic on the oceans is staggering.

How over 2 feet of rain caused historic flooding in Louisiana in less than 72 hours

How over 2 feet of rain caused historic flooding in Louisiana in less than 72 hours | Geography Education | Scoop.it
All-told, over 20 inches of rain fell in less than 72 hours around Baton Rouge.
Seth Dixon's insight:

Last month I was in New Orleans, and it rained for about 2 hours…it was staggering to see how many issues stemmed from that drainage in such a flat floodplain.  This is so much worse.  This article focuses on the weather/environmental situation, and this one on the political/human impact.

Live chart: Fish stocks

"The world's fish are in danger—as is everyone who depends on them."

Seth Dixon's insight:

Every semester I share with my students this New York Times video about the rapid rise in industrial fishing and the production of Talapia.  Even with the rise of aquaculture as a major source of seafood, the world's oceans are still depleted.  As the world's population rises, many folk cultures with their roots in small fishing villages have transformed into primarily urban societies, but these urban societies still have a strong cultural preference for seafood and consume at levels that are not sustainable.

Thanks to Humans, the Great Salt Lake Is Drying Up

Thanks to Humans, the Great Salt Lake Is Drying Up | Geography Education | Scoop.it
Diverting more water could pose serious health and economic threats to Utah.
Seth Dixon's insight:

Follow-up: The drying up of the lake can't be blamed on the current drought, this is a human-induced modification of the environment.  This lake is not exceptional, even if the imagery is startling.  Like many lakes in dry climates with growing populations, the people are using the freshwater flow into the lakes more extensively than they have in the past.  The Great Salt Lake, the Aral Sea, Lake Chad, Lake Urmia, and the Dead Sea are all drying up.

Mary Grace Bunch's comment, April 21, 10:21 PM
The Great Salt Lake in Utah is drying up which will lead to an unpromising future for the environmental health of the area. This is occurring due to the consistent reductions from rivers feeding into the lake that have been taking plays for 150 years. This past year the Great Salt Lake reached record low levels, dropping 11 feet. As a result of this increase in salinity and loss in half the volume of the lake, there is going to be trouble involving the economy and ecology of the state of Utah. This can be seen by dust storms or pollution.

The agglomeration of these rivers and gateways into the lake for human use are leading to the backwash effect. The backwash effect can be seen as the drained/dried out of water, an important resource to Salt Lake City, being drained in its regions. The impacts of the rivers outside of the lake are affecting the resources of the lake, even though it may not seem direct. Primary Economic Activities such as fishing will be impacted by the drying up of the Great Salt Lake. As a result of this, the development of Utah will be threatened. Utah is very reliant on the lake for it’s valuable resources that help them develop. A solution may be found through ecotourism. If the city is motivated in solving this problem, they could very well promote ecotourism in order to preserve the lake since Salt Lake City is very popular and many people travel there.

This article was relative to the Development Unit we are in now. It made me aware of what is going on in Utah. I never would have known this issue was occurring until I took the time to read it. I look forward to following along with this issue in the future and to see how the state of Utah will deal with it.
Kayla McIntosh's comment, June 1, 11:14 PM
I agree with Mary Grace that they should use ecotourism to conserve the Great Salt Lake. Since the Great Salt lake is so economically important to Utah, ecotourism would help bring money into the state and make people more aware on what human use of rivers can to do the environment, which will eventually dry up the river that can cause dust storms, creating more air pollution.

Utah's Great Salt Lake is shrinking

Utah's Great Salt Lake is shrinking | Geography Education | Scoop.it
Human activity is playing a role in the dwindling size of Utah's Great Salt Lake, according to new research.While the research group acknowledged the role that climate fluctuations, such as droughts and floods, have played in the shift of the lake's water levels over time, the decrease in the lake's size is predominantly due to human causes. According to the report, the heavy reliance on consumptive water uses has reduced the lake level by 11 feet and its volume by 48 percent.

 

Tags: physical, Utah, environment modifyenvironment, water.

Seth Dixon's insight:

The railroad causeway that creates the color difference between the northern and sotuhern portions of the Great Lake is as the Union Pacific plans to change the causeway; the proposed bridge would allow for the two distinct salinities to intermingle more.  Environmentally, this lake is not exceptional.  Like many lakes in dry climates with growing populations, the people are using the freshwater flow into the lakes more extensively than they have in the past.  The Great Salt Lake, the Aral Sea, Lake Chad, Lake Urmia, and the Dead Sea are all drying up.

Living Bridges

"In Northeast India just north of Bangladesh is the province of Meghalaya."

Seth Dixon's insight:

The living bridges of Meghalaya are truly sights to behold; these astonishing bridges are a natural way that local people have adapted to an incredibly flood-prone environment.  The organic building materials prevent erosion and keep people in contact during times of flood.  Here is another video and articles (BBC, Atlas Obscura, Inhabitat, and MNN) with more ecological and cultural context on these living bridges.

Climate Change Is Here

Climate Change Is Here | Geography Education | Scoop.it
Record heat, fading ice, and rising seas show how climate change is affecting us. But there’s new hope we can cool the planet. Here’s how.
Seth Dixon's insight:

The National Geographic Magazine has recently created this interactive to accompany the magazine article on climate change (for those worried that the editorial direction would not be as environmentally focused because of the recent changes for the National Geographic Society, I think this is a resounding way for them to emphatically declare that they are committed as ever to their core values and mission).  This interactive is richly-laden with videos, images and case-studies, showing the tangible impacts of climate change and lays out what the future implications of these changes.  The interactive is organized to answer these main questions:

  • How do we know it’s happening?
  • How do we fix it?
  • How do we live with it

Sarah Cannon's curator insight, November 25, 2015 10:15 AM

There is too much talk about helping the climate and environment. All politicians do is talk about cleaning the environment and having less pollution. Even Al Gore is big talk. I've only heard of little change. I want to see a difference. I want to see people actually doing things to help the environment. Enough talk. What should happen is a world wide clean up. Jobs should be created where people should clean in their own community. Its a simple job. Get a trash bag, get off your lazy butts, get out of the house, get a group together (who would be paid by the state) to pick trash up off the streets, beaches, trails in the woods, baseball fields, parks. This isn't hard to do. Not just one person, but if a group of people can come together and be employed by their state to clean their community, at least four days a week. There should also be a group of people, even fisherman to clean the ocean, go out and get what ever trash you can find. Using nets, and if fish are caught, throw them back in the ocean. Also, Trash Island has to be eliminated. It boggles my mind that who ever passed the law on trash being dumped into the ocean an Okay to do. Are you kidding me?? What is wrong with you? Our Earth is dying because of humanity. Also the oil spill that happened in 2012, I believe, I saw a man on the news that created a way to capture the oil floating on the surface of the ocean with a blanket like material, sure it would take a lot of those "blankets" but at least it would be helping to rid the ocean from oil. What are people thinking?? that the oil will just disappear?? Are you serious? So many people really have to open their minds. Look at what's happening you ignorant selfish fools. I will finish my rant right here.

When China Rules the Sea

When China Rules the Sea | Geography Education | Scoop.it
The United States is no longer the world’s only global naval power.


Why would China go to the trouble and expense of mounting an expedition to the northern climes in the Western Hemisphere? Because it sees value in staging a presence in distant waters. And because it can: Beijing no longer depends completely on its oceangoing battle fleet to ward off threats in China’s seas. It can now rain long-range precision firepower on enemy fleets from land. Ergo, the People’s Liberation Army Navy (PLAN) fleet can cruise the far reaches of the Pacific and Indian oceans or even beyond, without forfeiting China’s interests in waters close to home.  For China, the upsides of far-ranging maritime strategy are many and compelling, the downsides fewer and fewer.

Mark Hathaway's curator insight, November 24, 2015 7:07 AM

The nation that controls the seas, controls the world. Throughout history the leading Naval powers have always been the worlds most dominate nations. The greatest land forces, are no match for the supremacy of the seas. Not even Napoleon could beet back the power of a supreme navy( The British Royal Navy). Since the end of the Second World War, The United States navy has dominated the seas. That domination has made the U.S the worlds greatest nation over the course of the past 75 years. For China to displace the U.S atop the nations hierarchy, they most out due us on the seas. China is ware of this history, and that is why they are heavily investing in their naval technology. The key to the future, as it has been in the past, will be what nation can dominate the worlds seas.

Benjamin Jackson's curator insight, December 13, 2015 8:23 AM

the growing strength of the Chinese navy is worrying from a military perspective, as during the cold war one of the main reasons they were not considered as big a threat as the Russians was because of their inability to project force beyond mainland china. with their navel improvements this is no longer the case. what this will hold for the future, we can only wait and see.

The Ogallala Aquifer

The Ogallala Aquifer | Geography Education | Scoop.it
Hidden beneath the 245,000 square miles that make up the Great Plains, resides a lake that’s one of our greatest water assets: The Ogallala Aquifer. Haven’t heard of it? Farming the plains would be unprofitable at best without it, as shown by the Dust Bowl of the 1930s. At the time, the aquifer’s existence was known, but the technology to tap into it wasn’t.
Seth Dixon's insight:

Portions of the High Plains Aquifer are rapidly being depleted by farmers who are pumping too much water to irrigate their crops, particularly in the southern half in Kansas, Oklahoma and Texas.  This podcast explores the environmental and economic impacts of this unsustainable situation.

Sinkhole looks like an abyss, recharges aquifer

Sinkhole looks like an abyss, recharges aquifer | Geography Education | Scoop.it
At this sinkhole, about 500 cubic feet of water per second is disappearing into the earth, the equivalent of an Olympic-sized swimming pool every three minutes, according to an engineer with the Edwards Aquifer Authority. For as much water reaches the aquifer at this spot, far more infiltrates through porous rock across South-central Texas.
Seth Dixon's insight:

Not all water runoff goes to rivers, lakes, and oceans.  Some water percolates into soils that can absorb water (aquifers) but there are some soils such as clay that can't absorb water (aquicludes or aquitards).  In this dramatic example (see video), the water is not absorbed by the resistant rock, flows through a sinkhole to recharge the aquifer below.

Louisiana in Tough Shape

Louisiana in Tough Shape | Geography Education | Scoop.it
Unlike the many maps we have seen that show what Florida, Boston, or some other coastal location would look like with higher sea levels, the figure above compares the iconic outline of Louisiana with the present-day outline of its dry land. An important caveat is that some of the removed areas are wetlands, meaning they are not under water all the time, but those lands are not available for most human uses (aside from fishing), so this outline warrants attention.
Seth Dixon's insight:

Last month I was in New Orleans, Louisiana and I'm so disheartened to know that thousands have their homes under water.  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.

How Geospatial Analytics Are Changing Habitat Conservation

"The BirdReturns program is an effort to provide 'pop-up habitats' for some of the millions of shorebirds, such as sandpipers and plovers that migrate along the Pacific Flyway, a route that spans from Alaska to South America. Birds flying on this journey seek out the increasingly rare wetlands teeming with tasty insects to fuel their long-distance flights.  Over the last century, California's Central Valley has lost 95% of the wetlands habitat to development, agriculture, and other land use changes. As a solution, scientists use big data, binoculars, and rice paddies."

Seth Dixon's insight:

This project combines data from satellite imagery to map surface water in California's Central Valley, and individual bird observations to select locations that can be temporarily converted into wetlands to aid the migratory birds (for more information than the video provides about this project, read this article). 

 

This is a great example of using both 'big' geospatial data as represented by the satellite imagery and combining it with field data and actual observations to make the world a better place.  We need more decision makers that can think spatially and use geographic skills.

Your Backyard is Bigger Than What You Can See | Geography Education | Scoop.it

“Geography is linked to the environment,” says Connie Wyatt Anderson, of Canadian Geographic Education. “In the Lake Winnipeg watershed, what you throw into the Bow River in Calgary eventually ends up in Hudson Bay.”

Seth Dixon's insight:

More than anything I love the idea of using watersheds to connect students to their location environment and to think about places that are beyond the backyard, but are connected to them.  If they see themselves as more intimately connected to these places, it can only increase their spatial awareness, geo-literacy and hopefully their commitment to protect their expanded backyard.   This is an effective way to help students 'jump scale' in a way that will still keep things relevant to their lives.

The Marshall Islands Are Disappearing

The Marshall Islands Are Disappearing | Geography Education | Scoop.it
Most of the 1,000 or so Marshall Islands, spread out over 29 narrow coral atolls in the South Pacific, are less than six feet above sea level — and few are more than a mile wide. For the Marshallese, the destructive power of the rising seas is already an inescapable part of daily life. Changing global trade winds have raised sea levels in the South Pacific about a foot over the past 30 years, faster than elsewhere. Scientists are studying whether those changing trade winds have anything to do with climate change.

Mark Hathaway's curator insight, December 12, 2015 6:21 AM

Climate change is a controversial issue in the United States. The debate over climate change in our current political environment is stuck in a denial or belief stage.  It is foolish to deny that our climate is changing. The overwhelming majority of scientists have provided the world with data, that proves that man is altering the climate. Those who deny climate change, probably do not really believe that it is not occurring.  They are denying climate change, because they do not favor altering our economic system in an attempt to stop the phenomenon. To really effect climate change, major changes are going to have to be made in the way we consume our energy. Our current political environment cannot and will not implement these changes. As with most problems, nothing will be accomplished until a large swath of Florida is underwater.

China's Maritime Claims

ONE reason China’s spectacular rise sometimes alarms its neighbours is that it is not a status quo power. From its inland, western borders to its eastern and southern seaboard, it claims territory it does not control.
Seth Dixon's insight:

Many of the geopolitical conflicts in the East Pacific have their roots in the territorial disputes over islands that at first glance seem as if they wouldn't be worth the trouble; how did this become a tense situation?  Since the UNCLOS agreement gives countries 200 nautical miles off their coasts to be an Exclusive Economic Zone, that greatly enhanced the strategic value of controlling these islands and the shipping lanes.  The United States, to counter Chinese claims, has used the Navy to go near some of the claimed (and reclaimed) islands recently.  This interactive map briefly highlights some of the details behind the conflicts with links for further readings. 


Questions to Ponder: Why do countries care so much about some minor islands?  Why would other countries not want to accept China's territorial assertions?

Chinese expansion into the South Sea has been a longtime coming, and China's actions in the region are both a reflection of its growing strength and a huge diplomatic headache for the US and every other nation in the region. China's construction of artificial islands allows it to claim autonomy over a larger body of water, challenging the maritime power of every other nation in South East Asia, many of whom have economies reliant on the waters China now claims as its own, some 500 miles away from the Chinese mainland. With the emergence of the Chinese economy as a global power, its ambitious leaders have made plans to transform China from a regional military force to a new superpower- one that the established order, the US included, is entirely unsure of. Which of these nations can truly challenge China's decision to make these waters it's personal pond? It would be economic and political suicide, as China is an enormous global trading power, and has the potential to crush any of these nations in a military engagement. Could Japan? Perhaps, but the Chinese have already pressed ahead with their plans, regardless of Japanese political pressure. Involvement of the US is perhaps the last thing anyone wants- particularly both the US and China- but it is perhaps the only way China will heed pressure from abroad and cease  Chinese expansion in the region. The US and China must be allies, for the sake of global prosperity, but actions like these cannot be tolerated, by either party.

One reason to care about minor islands is the 200 nautical miles off the coast for the EEZ. This would give china more water territory for drilling of oil which I believe is there in those waters. Flexing more muscle for their navy to grow. Strategically the Chinese could take over these small islands and build air strips for future which would give them a chance to reach places they wouldn't be able to before and this would be good supply transactions during war, fueling, maneuver of man power. The other small countries also would lose their independence and would have to fall under china's rule. With the building of the man made islands and the Chinese navy protecting their people while they continue to build these islands and daring anyone to try and stop them is a sign that china is trying to dominate and expand with muscle. It is their time they have the economic, and military power to do so. Of course they don't want to deal with the u.s. and their allies militarily but it doesn't benefit the u.s. either. I don't believe u.s. wants to get involved in a battle with china and their allies.

Claiming territory it does not control, causes a lot of controversy with other country. The main problem here now is China is having a dispute with Japan about some islands. There could possibly be oil or natural resources.Japan says that the land was always theirs. China clearly likes to just put itself out there and make claims or place oil rigs wherever. This could be a big problem for them because if someone gets too offended by their actions there could end up being a war or some sort of conflict. Especially since they like to use military forces such as navy and air guarding "territory."

Changes in Three Gorges Dam

NASA's animation of China's Three Gorges Dam construction over the years.
Seth Dixon's insight:

The world’s largest dam was created to generate more energy for China’s ever-expanding economy and to increase the interior economic development by increasing the navigability of the river.  The dam also can control downstream flooding and protect important industrial centers such as Shanghai.  This ambitious hydroelectric dam produces the same amount of energy as 18 nuclear power plants.  This dam also displaced over 1 million people as the reservoir flooded properties upstream.  The Three Gorges Dam prevents the nutrient-rich sediments from being deposited downstream; this heightens Chinese farmers’ need for fertilizers, this has led to drought downstream and limits residents’ water access. The dam also disrupted the local ecology (part of the reason the Yangtze River Dolphin went extinct), preventing fish to migrate to upstream breeding grounds. 

For good and ill, the dam has profoundly modified the environment and this video animation from NASA is a powerful demonstration of the changes.

Inland water - environmental change 

Benjamin Jackson's curator insight, November 9, 2015 5:40 PM

The impact of the Three Gorges Dam on the residents upstream is amazing. I cannot imagine anything like this happening in the US, mostly because of the impact on the people both upstream and downstream. Ecological damage from this dam may not phase the Chinese government, but I think any North American or European government would shudder at the thought of the backlash among their citizens this would create.

Matt Ramsdell's curator insight, December 14, 2015 9:27 PM

Three Gorges damn in China is the largest dam ever constructed. This was created to save on power by creating hydroelectric power for the people of the land. One of the issues with this was the the flooding of the land up streams displacing millions of people. It created a larger up stream area and very small down stream. A lot of the people that lived up stream had to be relocated further inland and faced changing climatif weather. The banks of the river are carved out between what seems like mountainous regions so as you move more uphill the weather and temperature will be a whole new category of life (Depending on how far you relocated).

How being surrounded by water made the Dutch different

How being surrounded by water made the Dutch different | Geography Education | Scoop.it
While researching a book on ‘Why the Dutch are Different’, Ben Coates realised that an amazingly large number of the things which an outsider might think of as ‘typically Dutch’ could be explained at least in part by a single factor: water.
Seth Dixon's insight:

Cultural, political and economic patterns of a region are heavily influenced by the environmental settings.  Occasionally though, geographers can get overly-cautious when discussing how the environment can shape culture, worried about straying into realm of environmental determinism.  However, environmental factors can profoundly influence cultural attributes.  This article shows how Dutch cultural attributes such as diet, history, politics and landscape are influenced by their maritime physical setting.

Tsunami Animation

"The largest earthquake ever recorded by instruments struck southern Chile on May 22, 1960. This 9.5 magnitude earthquake generated a tsunami that crossed the Pacific Ocean, killing as many as 2000 people in Chile and Peru, 61 people in Hilo, Hawaii, and 142 people in Japan as well as causing damage in the Marquesas Islands (Fr. Polynesia), Samoa, New Zealand, Australia, the Philippines, and in Alaska's Aleutian Islands.  To see how this tsunami compares with two recent tsunamis from Chile, please watch http://youtu.be/qoxTC3vIF1U "

Seth Dixon's insight:

In 1700, Japan was hit by a tsunami; they knew that tsunamis were caused by earthquakes, but there was no earthquake of that magnitude in Japan that could have caused it.  They called it the Orphan Tsunami, and it puzzled everyone.  Centuries later, data confirmed that a massive earthquake in the Pacific Northwest occurred in 1700 and it's tsunami traveled across the ocean much like the this computer simulation of the 1960 Chile earthquake.
