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

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

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]

When it snows, it pours (into aquifers)! Recharge seasonality around the world…

Written by Scott Jasechko University of Calgary isohydro.ca twitter.com/sjasechko Groundwater is renewed by rain and melted snow that moves under the ground, a process called groundwater recharge. The percentages of summer versus winter precipitation that make it under the ground are expected to be different for a number of reasons including larger plant water use during the summer, and larger are ...[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]

Is research on ‘regional groundwater flow’ stagnant or still flowing?

Is research on ‘regional groundwater flow’ stagnant or still flowing?

Written by Brian Smerdon IAH regional groundwater flow commission In the early 1960’s József Tóth published seminal work on the concept of regional scale flow and nested flow systems. His work built on the “theory of groundwater motion” by M.K. Hubbard, and seemed to come along just at the right moment in history of hydrogeology. Armed with József Tóth’s work, the hydrogeologic community (geologis ...[Read More]

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

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]
