Meagan Harpin's insight:

This amazing pink lake is located on Middle Island in Western Australia. It is rimmed with white salt and surrounded by a forest of dark green. The reason for the coloring of the lake are still a mystery. I would love to travel to see this amazing lake this is absolutley incredible!

The pink lake, Lake Hillier,  located in Western Australia is stunning. The aerial view of the lake makes the lake seem unreal that is was is fascinating. What gives the lake its pink color is a mystery, but it may be from bacteria, but it shows how some places in the world are affected differently than others and it produces remarkable results.

Nicole Kearsch's curator insight, December 17, 2014 1:48 AM

Now this is bizarre.  A pink lake and no one is really sure as to why it is pink.  It is not on the top of my list of places to go swimming, that is for sure.  Although scientists don't seem too concerned about the safety of the lake for people but are curious as to what is causing the lake to be pink.  Thoughts on algea and bacteria levels or the amount of salt are included in the potential reasoning for the pink color.  Even on google earth you can see that the lake is in fact pink.  Even when scientists come to a conclusion as to what is causing the pink colored lake, as far as it isn't causing any environmental issues, I think that the lake should be left pink as a type of wonder of the world attraction for people to see.

Lena Minassian's curator insight, May 7, 2015 11:54 AM

This article caught my eye because I have never seen a pink lake before. This lake is on Middle Island in Western Australia. The lake is 600 meters wide but the reasoning behind the color of it is still yet to be determined. White salt rims the lake and the color may be caused from a low nutrient concentration and even just bacteria. The pictures of this lake are beautiful and there is not anything like it.

Penguins from Space: A New Satellite Census Doubles the Known Population of Emperors

Penguins from Space: A New Satellite Census Doubles the Known Population of Emperors | Meagan's Geoography 400 | Scoop.it
High-resolution imaging has allowed scientists to produce the first full count of Antarctica's emperor penguins...

 

Before this, there was no way to to gather reliable penguin statistics.  Geospatial technologies are now providing us the tools to teach us more about the biogeography of penguins.  The applications of geospatial technologies are endless.

Meagan Harpin's insight:

Using high resolution images from satilites geographers and ecologists are looking at emperor penguins. They have come up with the first ever population total of 595,000 penguins which is nearly twice as many emperor penguins as previous studies. They also counted 46 colonies. This is so cool, Penguins are one of my favorite animals and are so fasinating to me.

In the beginning of the semester we talked about how geography is always changing. Our understanding of geography does as well. This new technology helps people have a clearer picture of the wildlife that exists on Antarctica. Because of its harsh environment the amount we know about this barren continent has been limited. As technology improves we will be able to gain more accurate information about Antarctica.

Hector Alonzo's curator insight, December 16, 2014 12:58 PM

Using this new technology, animal can be monitored and helped by the satellites. Having a way to accurately know the population of a species is incredible,  because now we can know which species are in danger of extinction and we can take steps to help them. Before the use of the satellite,  the population of Emperor penguins was found to be 595, 000 and the colonies of penguins was found to be 46 instead of the previous 38, so without this technology there have been penguins that may have needed help, but now they will get proper attention.

Kendra King's curator insight, April 13, 2015 9:27 PM

Technology never ceases to amaze me. As the article described, the use of satellite imagining recently showed that the “population count” of the emperor penguin is “found nearly twice as many...as did previous studies.” Prior to the use of satellite imaging, the method to obtain this type of data was done by people actually being around the area. As the new numbers showed this was inaccurate because so much of the artic can’t be reached by the human population. I think this brings up an interesting notion. We define our landscape based on what we see. Yet, what we see doesn’t always capture what is actually on earth. As such, I wonder if more penguin colonies have disappeared then the one the British intuition noticed. We won’t know, but at least now thanks to technology a better grasp of the situation can happen. Maybe with more concrete data about the effects of global warming on Antarctic more non-believers could be swayed. All in all, I think the technology is beneficial. The only down side about this technology is the possibility for misuse. If we can now figure out the penguin population down to which ones are adults, imagine just what else this technology can due in the name of “geographic research.”

Aborigines threaten to shut Uluru

Aborigines threaten to shut Uluru | Meagan's Geoography 400 | Scoop.it
Aboriginal leaders threaten to ban tourists from a top Australian landmark in protest at "racist" government policies.

Via Seth Dixon
Meagan Harpin's insight:

This is a very strange article. After police and troops were sent into more than 70 indigenous communities after a report of wide spread child abuse tribal leaders threatened to ban tourists from being allowed to climb Uluru. TO me this sounds like they are trying to hid what is really going on in their communities.

Matthew Richmond's curator insight, December 2, 2015 3:38 PM

Re-scooped from Professor Dixon, this article is about Aborigines in Australia protesting "racist" government policies. It sounds like the Australian version of what would happen if America's Native Americans teamed up with a racial oppression organization. They are apparently threatening to shut down the most famous landmark in Australia to visitors if the government doesn't change it's position. I don't blame them, fight the power!!

Gene Gagne's curator insight, December 10, 2015 7:08 PM

the government punishing a whole culture for crimes is outrageous. Not all are guilty but all are punished. it is proven fact that more minorities in this country are incarcerated for drug usage than whites but that doesn't mean you jail all black people. The government is being racist because the aboriginal are poverty stricken group who do not contribute to society, they only have a population of 300,000 people. In the governments eyes they just exist on the land and do nothing for the economy. Well it must have some influence because they are protesting by not allowing tourists climb Uluru or Ayers rock. I guess the government will not be collecting permit fees or other fees associated with the climbing of the rock. Tourism should take a hit from hotel accomendations  to hiking tour guides to purchasing gear etc...

Benjamin Jackson's curator insight, December 14, 2015 12:22 PM

Australia has always had troubles dealing with their past actions against the native population of their island, and this will hopefully be a wake up call on the policies they have taken.

Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years

Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years | Meagan's Geoography 400 | Scoop.it
The insect is so large — as big as a human hand — it's been dubbed a "tree lobster." It was thought to be extinct, but some enterprising entomologists scoured a barren hunk of rock in the middle of the ocean and found surviving Lord Howe Island...

 

Island Biogeography is endlessly fascinating and provides some of the most striking species we have on Earth.  The physical habitat is fragmented and the genetic diversity is limited.  Within this context, species evolve to fill ecological niches within their particular locale.  This NPR article demonstrates the story of but one of these incredible species that never could have evolved on the continents.  In modern society, more extinctions are happening on islands than anywhere else as 'specialist' species are in greater competition with 'generalists.'

Meagan Harpin's insight:

Pictured above is what is left of a volcano called Ball's pyramid. It emerged from the ocean 7 million years ago and sits just off of Australia in the South Pacific. This rock also hides a secret, it is home to a six legged stick insect 12 centimeters long and the heaviest flightless stick insect in the world. If I had found those bugs I would not have been a happy camper!

Joseph Thacker 's curator insight, April 25, 2014 10:35 AM

On Ball's Pyramid the stick insect is different than any other insect I have seen. The size of it is terrifying, as it as big as a human hand. There are many different kinds of animals or insects someone can find on remote islands, islands such as Madagascar, Australia and even on this small island, which is located off of Australia's coast in the Pacific.    

Jacob Crowell's curator insight, December 15, 2014 4:40 PM

Isolation can lead to some remarkable examples of evolution. This "tree lobster" is an example of that. On an island cut off from many predators and hold little resources, the tree lobster has found a way to survive.

Felix Ramos Jr.'s curator insight, May 7, 2015 9:52 PM

A truly remarkable story.  A prehistoric 'stick' insect that lived on an island off the coast of Australia was obliterated by rats that came to the island on English ships.  Everyone thought they were extinct until one day some researchers found 24 of them living on a remote piece of land not too far from the insect's homeland.  This was an uninhabited piece of rock, essentially, with very little to offer any life form but the stick insects found just enough to survive.  How they got here is unknown but after the find and a sleepless zoo worker, this insect is flourishing in captivity.  The move to release them back into the wild is ongoing.
