Until now, there has been a lack of solid, comprehensive spatial data about African groundwater resources. Researchers have now done so. For a more academic article on the subject, here are their findings in Environmental Research Letters.

the undersea work & world of Michael Lombardi...
Michael Lombardi is a both a scientific and commercial diver; as an author and environmentalist and an Explorer in Residence with the National Geographic Society. This Saturday he will be the guest speaker for the Rhode Island Geography Education Alliance meeting and I am incredibly excited to hear from him.

The natural landscapes shown as captured by satellite imagery is as beautiful as anything artists have ever created. Some of the colors shown in the video may seem otherworldy. Most of those color anomalies are due to the fact that remotely sensed images have more information in them than just what we see in the visible portion of the electromagnetic spectrum. Some of these images are processed to show different bands so we can visually interpret data such as what is in the near infra-red band, skewing the color palette.

This map represents the 1079 earthquakes with magnitudes higher than 2.5 that have occured in the last 30 days. You can customize the map to display different data at any scale. There is detailed information about each earthquake in this great dataset.
The 1980 Mount St. Helens eruption was one of the most significant natural disasters in the U.S. in the past half-century. Landsat captured the extent of, and recovery from, the destruction.
The accompanying satellite images (also compiled in a video to show the temporal changes) demonstrate one way that remote sensing images can help us better understand the spatial patterns in the biosphere.

Sometimes whe teach human geography as though it is not connected to physical geography. The geographical distribution patterns of agriculture are some of the most highly correlated human activities to the physical environment. This one, dairy productivity, changes greatly based on temperatures, humidity and latitude.
This strangely beautiful map shows every tornado to hit the U.S. between 1950 and 2011. What physical geographic factors lead to this distribution? What are the impacts of this data on human geography?

The physical environment will be altered as the World Cup comes to Qatar in an attempt to raise their global economic profile and to present themselves as more culturally comsopolitan. Except there is that desert conundrum of having soccer matches in the middle of the desert in the dead of summer. This shows the technological efforts to redefine confortable weather conditions. This is a good Ted talk that combines cultural, economic and physical geographic factors in the Middle East.

This is a gorgeous set of 39 images that are all view the Earth and captures images for above. These aerial photography and remote sensing images focus of a wide range of topics such as the cultural landscape, the environment, earth science, cultural ecology and urban systems. The photo above is of Mont-Saint-Michel, a tourist attraction and UNESCO world heritage site in northwestern France that is the world's premier example of the tombolo landform.

Here is a link to some data that backs up what most Americans already knew: the month of March was much warmer that just "unseasonably warm." IN the Northeast, it was 9.8 degrees (F) above the average, and the warmest March in 118 years.

3D NASA images show the magnitude of last week's storm in Texas was immense, vertically towering 8 miles above the Texas landscape. The storm "spawning 14 tornadoes and golf ball sized hail was immense...[NASA's] Tropical Rainfall Measuring Mission (TRMM) satellite watched the storm develop and measured its cloud height at above eight miles high."
This interactive map is a 'nearly live' dynamic display of United States winds patterns (speed, direction and broad spatial context). Click on the image to see the animated, large version. Super cool!!
Who says you can't integrate geography and real world applications into the math curriculum? Paul Bouke has scoured the Earth searching for fractals in the natural environment and created this amazingly artistic remote sensing gallery (with KMZ files for viewing in Google Earth as well).

This blogpost answers the (often unasked) question: What would the world be like if the land masses were spread out the same way as now - only rotated by an angle of 90 degrees? While purely hypothetical, this is an exercise in applying real geographic thinking to different situations. Anything that you would correct?

This a visually stunning video montage with clips compiled from the Discovery Channel's series "Planet Earth."
While I do enjoy this video, it is especially interesting in in how it conceptualizes the world in the two frames. Urban, human, civilized society on one side, with natural, unsettled wilderness on the other. The video attempts to bridge the divide, hoping that more people will see more interconnections between the human/urban world and the natural/wildlife world. While geographers recognize that all elements of the planet are interconnected, most people still think of the world through dichotomies such as these: civilization vs. wilderness, cultural vs. natural and human vs. animal. How do these terms shape our thinking about the world?
The lithosphere (Earth's crust) is a hard, rigid plate on top of a softer molten layer known as the asthenosphere. Sounds like an Oreo to me! As a crude analogy that lets you bring food into the classroom, this lesson on plate boundaries sound like a winner. Read this for an academic article on how to use Oreo's to teach about Earth's crust.
NASA researchers are expressing concern about something they've never seen before: the melting of ice across nearly the entire surface of Greenland earlier this month.
Climate changes are afoot in the Arctic and the Greenland ice sheet. For more on the Arctic. In related news, Texas and Louisiana have introduced education standards that require educators to teach climate change denial as a valid scientific position. South Dakota and Utah passed resolutions denying climate change. Tennessee and Oklahoma also have introduced legislation to give climate change skeptics a place in the classroom.
This map of all the world's recorded earthquakes between 1898 and 2003 is stunning. As you might expect, it also creates a brilliant outline of the plates of the Earth's crust—especially the infamous "Ring of Fire" around the Pacific Plate.
The plate boundaries are amazingly vivid in this geovisualization of the all the earthquakes over a 105 year span. How did scientist orginally come up with the theory of plate tectonics? How did spatial thinking and mapping play a role in that scientific endeavor?
If we accept that controversial dams will continue to be built for economic benefit, how can we limit their damage on the environment?
"Of all the ways we have engineered Earth in the Anthropocene, the Age of Man, surely nothing rivals our audacious planetary-wide re-plumbing of the world's waterways. But is our control of Earth's arteries causing dangerous clots?" The human-environmental interaction theme of geography is as readily apparent in this issue as any.
This is a great set of images that show coastal processes for a geomorphology or physical geography class. Pictured above is Palm Bay, Australia, which also happens to show fluvial processes as well.
After just two years in orbit, ESA's GOCE satellite has gathered enough data to map Earth's gravity with unrivalled precision.
Gravity isn't the same everywhere. "ESA's GOCE mission has delivered the most accurate model of the 'geoid' ever produced, which will be used to further our understanding of how Earth works. The colours in the image represent deviations in height (–100 m to +100 m) from an ideal geoid. The blue colours represent low values and the reds/yellows represent high values. The geoid is the surface of an ideal global ocean in the absence of tides and currents, shaped only by gravity. It is a crucial reference for measuring ocean circulation, sea-level change and ice dynamics – all affected by climate change." Follow the link to see an animated version.
More than half of the UK population cannot see the stars clearly because of light pollution, campaigners say.
Another impact of modern technology, urbanization and living in affluent consumer-driven societies.
Pumice-like cratery indents formed by ancient raindrop splats are adding to the mystery of why the adolescent Earth was warm enough to host rivers and oceans, despite the dim sun of the day. Thanks to fossilized impressions from rains that fell down on Africa 2.7 billion years ago, the "Faint Young Sun" paradox is getting curiouser and curiouser.
