Stranded trawlers of the Aral Sea


Aral Sea which lies between Kazakhstan and Uzbekistan, was once amongst the 4 largest lakes in the world. It has now shrunk to 10% of its original size. Global Warming has nothing to do with this disaster. The Aral Sea has been steadily shrinking since 1960's when the Soviets started diverting the rivers which fed into the lake, for irrigation purposes.

Two weeks ago, the U.N. Secretary-General Ban Ki-moon said that the drying of the Aral Sea was
one of the world's most shocking disasters.

One of the consequences of the lake's dwindling size has been the death of the fishing industry on the lake and fishing trawlers have been left stranded in what are now sandy wastelands.

Mibazaar has put together this Google Maps mashup to take you on a tour of some of the stranded trawlers that once fished these waters.
So as the Aral Sea was shrinking it left behind trawlers which had no where to go and were stranded. Some of these stranded trawlers can be clearly seen in Google Maps. Virender Ajmani, the author of the mashp has counted 10 but it's obvious there are many many more. If you find more, please do let him know and he will add it to this map.

Explore the ocean with interactive tours in Google Earth

At the beginning of April, Google announced a new default layer for oceans in Google Earth.
The new oceans layer includes hundreds of sites generated from data, images, and videos from organizations like National Geographic, NOAA, and dozens of others.

National Geographic ocean explorer,
Sylvia Earle, narrates a highlight tour through some of the best photos and videos in the 'Explore the Ocean' layer in Google Earth :

In the same
announcement, Google featured a new narrated tour called Hope Spots in the Ocean Showcase which displays eight places around the world considered to be indicative of the health of the world's oceans and marine life.

Quiet moods meditative moments




As hundreds of thousands of air passengers disrupted by the consequences of the Icelandic volcano ashes, two of the three creators of the Marine GeoGarage are stranded abroad : Loïc in Barcelona (Spain) and I in Dakar (Senegal) travelling for business.

So waiting the resuming of the passengers flights, we have to be patient, reading, watching movies or listening music, tracks such as "The Young Daughter of the Sea" from the 1973 album "L'Apocalypse Des Animaux" composed, arranged, produced and performed by Vangelis...

This is a new example showing we need to take into account how fragile the human race really is to vagaries of nature.

Image of the week : Easter Island, the most isolated island in the world

Seen from space, Easter Island (Rapa Nui) looks anything but egg-shaped (GeoGarage location)
The German Earth observation satellite TerraSAR-X flew over this small and remote volcanic island, acquiring snapshots that show that man-made structures can be seen easily even from space. This image shows the principle town of Hanga Roa, on the northwestern coast (in yellow), and the airport, in the western part of the island (black line).

The island is has an area of just 160 square kilometres and owes its name to the Christian festival of Easter. The Dutchman Jakob Roggeveen landed on its shore on Easter Sunday, 5 April 1722, and chose the rather unimaginative name.
Located about 3600 kilometres from the mainland of Chile and more then 4000 kilometres from Tahiti, Easter Island can justifiably be described as the most isolated island in the world. The nearest neighbours – about 50 descendants of the mutineers on the British naval vessel HMS Bounty – live 2000 kilometres away on the small island of Pitcairn.

James Cook, who stopped at Easter Island in 1774 during his second expedition to the South Seas, was less than delighted with the island.
He wrote in his journal: "No Nation will ever contend for the honour of the discovery of Easter Island as there is hardly an island in this sea offering less refreshments, and conveniences for Shipping than it does."
This is no surprise: the island was formed when lava flows from three volcanoes joined to form a landmass between them.
