Elections may be a catalyst for deforestation, new research suggests

Democratic elections may be a catalyst for deforestation, according to new research. A study that examined deforestation rates during election years found that competitive elections are associated with higher rates of deforestation. The reason? Politicians are trading trees for votes, according to the researchers.

Study suggests heavy rains from tropical cyclones distort the ground below

Earth’s surface is constantly shifting, expanding and compressing in response to atmospheric and hydrologic forces from aboveground. A new study finds that compression of Earth’s crust is correlated with heavy rainfall from hurricanes and typhoons, known collectively as tropical cyclones. The added weight of all that water likely causes the ground underneath the storm to deform, according to the study’s authors.

Monday Geology Picture: Vintage Field Vehicle

I really enjoy looking at old geology textbooks, which often have incredible photos and drawings in them. For example, check out the above photo from an old geology textbook that I picked up at a secondhand bookshop. Look at that vintage field vehicle! Does anyone know what kind of car that is? The information in old geology textbooks (especially ones published before plate tectonics was understood) is often incorrect, but …

Safuna & Arhuey Glacier, Peru Retreat from Lakes

Safuna Glacier (S) and Arhuey Glacier (A) in 1992 and 2017 Landsat images indicating glacier retreat from the 1992 terminus red arrow to the 2017 terminus position yellow arrow.  Snowline indicated by purple dots. Safuna Glacier (S) is at the northern end of the Cordillera Blanca Range, Peru flowing north from Nevados Pucajirca.  Arhuey Glacier (A) is adjacent to Safuna and flows west formerly terminating in Arhuey Lagunacocha impounded by …

Sols 1927-1928: Layers of fun!

Today’s image is a color version of part of the workspace image from the Sol 1925-1926 blog, which shows in greater detail the numerous layers and color variations that kept us at this spot for another round of science observations.

A Tanzanian groundwater safari through the last 2 million years

Watching our backs in case of predators, we ventured out of the safety of our Land Rover for Gail to sample the lake water, as salt blew in drifts around us off the desiccated edges of the lake bed…

Scientists sift through lunar dirt for record of early Earth’s rocks

A team of scientists are examining crushed rocks brought back from the moon by Apollo astronauts for evidence of minerals that might have been formed in the presence of water to better understand the early formation of Earth. They presented the preliminary results of their work last month at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Thoughts and Images of The Great Blizzard of 2018

Working on the Eastern Shore of Maryland, you might imagine I have been rather busy over the last few days and that is beyond an understatement. I was brought to work today in a four-wheel drive jeep and I have 11″ of snow on my sidewalk! This was a memorable storm and perhaps what makes it more so is how fast the pressure in the storm dropped. The pressure in the …

Scientists help Costa Rican community manage dwindling water supply

As part of an interdisciplinary, international research team called FurturAgua, researchers from the University of British Columbia and Simon Fraser University have developed a tool they call the Groundwater Recharge Indicator for two watersheds in the Guanacaste Province of Costa Rica. The Groundwater Recharge Indicator can help community leaders prepare for the dry season by providing an estimate of water availability based on rainfall during the wet season. With this new tool, authorities can implement water conservation efforts such as collecting rainwater or using surface water instead of groundwater before the dry season begins and potential droughts occur, according to the researchers.

Researchers develop model that could reduce wave-induced injuries to Delaware beachgoers

Being pummeled by a large wave can quickly ruin a perfect beach day, as it may require a trip to the hospital or even worse. But researchers in Delaware have developed a new method that could predict when wave-induced injuries are most likely to occur, potentially reducing incidences of these injuries to unsuspecting beachgoers along the state’s coast, according to scientists who presented the research last month at the 2017 American Geophysical Union Fall Meeting in New Orleans.
