Geology Photo of the Week #44

Geology Photo of the Week #44

For a bit of a change of pace the photo of the week this week isn’t a photo at all. Rather it’s a fascinating model output showing ocean surface currents in the North Atlantic. The Gulf Stream is clearly visible as it flows past Atlantic Canada and out towards the middle of the north Atlantic. I am guessing that colour scheme has something to do with current velocity or mass flux or so ...[Read More]

Imaggeo on Mondays: Strombolian eruption

Imaggeo on Mondays: Strombolian eruption

Jonas Kuhn, a researcher at Heidelberg University , took the photograph during a field campaign at Stromboli volcano in Italy. The objective of this campaign was to gather data from different gaseous compounds of the volcanic plume. Via emission fluxes of volcanic gases (e.g. SO2, CO2, halogen compounds…) or the ratio of emitted gases, one can retrieve information about the interior of the v ...[Read More]

Booming Beijing: the impact of urban growth on local environment

Booming Beijing: the impact of urban growth on local environment

The global population is ever-growing. Cities are expanding at a rapid pace. A recent study by Mark Jacobsen of Stanford University and Son Nghiem of NASA’s Jet Propulsion Laboratory investigated the urban growth of Beijing, China (published on June 15th in the Journal of Geophysical Research – Atmospheres). Their results showed that the city had quadripled in size in the span of a dec ...[Read More]

Geosciences Column: When water is scarce, understanding how we can save it is important

Geosciences Column: When water is scarce, understanding how we can save it is important

Supplies of water on Earth are running dry. The rate at which an ever growing population consumes this precious resource is not matched by our Planet’s ability to replenish it. Water scarcity is proving a problem globally, with regions such as California and Brazil facing some of the most severe water shortages on record. Used for drinking, agriculture and industrial processes, water forms an fund ...[Read More]

Geology Photo of the Week #43

Geology Photo of the Week #43

This weeks photo can be described by one word: mesmerizing. Honestly, it’s hard to tell which part of this photo is better, the beautiful starry sky backdrop or the glow of Kilauea’s smoking crater. Combined, it’s just fantastic. Kilauea is part of the Hawaiian Island volcanic chain which has been formed as the Pacific plate has moved across at hotspot. The volcano is about 300,0 ...[Read More]

Imaggeo on Mondays: The place where water runs through rocks

Imaggeo on Mondays: The place where water runs through rocks

Antelope Canyon, located in Arizona, USA, was formed by erosion of the Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes (think of physical weathering processes such as freeze-thaw weathering exfoliation and salt crystallisation). Rainwater runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the ...[Read More]

Commentary: ‘Globalize Geoscience’ and International Capacity Strengthening

Commentary: ‘Globalize Geoscience’ and International Capacity Strengthening

The international community will soon agree on a set of sustainable development goals. This is a significant moment for the international community, and a great opportunity for geoscience. Over the coming months a broad discussion is needed as to how we can best support this global effort to eradicate extreme poverty. One important way this can be done is through ‘globalizing geoscience̵ ...[Read More]

Science and Shovels: Traversing across the Greenland Ice Sheet.

Science and Shovels: Traversing across the Greenland Ice Sheet.

Moving 150 tonnes of equipment more than 450km across the Greenland Ice Sheet sounds like a crazy idea. In that context, moving a 14-metre high, dome-shaped, wooden structure seems like a minor point, but it really is not. I do not think I realised what an awesome and awe-inspiring project I was part of, until I was out there, in the middle of the blindingly white ice sheet, and I saw the enormous ...[Read More]
