Centennial E10 – Volcano Disaster Prepping

Mon, 09/23/2019 - 9:16am

Many people have emergency kits packed to flee or survive forces of nature like floods, hurricanes, or wildfire. But what do you throw in your bag when you expect to rush toward a natural hazard? Geologist John Ewert has his go-kit packed with portable seismometers and gas-monitoring equipment, ready to mobilize when a volcano starts to rumble.

New study complicates theory that ancient impact pierced Moon’s crust

Mon, 09/23/2019 - 9:00am

A new study finds the crater’s crust mainly consists of a common lunar crustal mineral not detected in earlier analyses. The new results suggest the basin floor may not have exposed lunar mantle material as previously reported. “We are not seeing the mantle materials at the (Chang’E 4) landing site as expected,” said Hao Zhang, a planetary scientist at the China University of Geosciences, Wuhan, China, and a co-author of the new study.

Straight Talk From an Expert on Climate Change

Fri, 09/20/2019 - 11:29pm

This is why Katherine Hayhoe got the UN Champion of the Earth Award this month. She deserved it. This is how you communicate science. From her Twitter feed on August 23rd:   And the response when Dr. Hayhoe posts things like this: …and the truth of the matter is that those who claim it is not real are not basing their opinion on fact or evidence. It’s based on FEAR: …

This is an ex-eruption!

Fri, 09/20/2019 - 12:30pm

Recently, as chronicled in Scientific American, I was involved with amending the eruptive record at California’s Mount Shasta to remove an eruption that was supposedly seen by a French mapping expedition in 1786. USGS researchers had already been puzzling over it for years – evidence was slim, since the area was already prone to forest fires and there was nothing in the geologic record to suggest that it happened. William …

How to Take Advantage of Networking and Software Training

Thu, 09/19/2019 - 10:31am

“We’ve had an overwhelming response and fortunately, your application has been successful.” This is the type of favourable reaction everyone wants to achieve. I was fortunate enough to be accepted into a three-day long software training program at Datamine, in order to learn about their new software called Map Info. The knowledge provided throughout the course was exceptional, but the networking expertise gained from this experience was undeniably the most invaluable …

Storytelling basics: The story arc

Thu, 09/19/2019 - 9:58am

By Shane M Hanlon  All good stories have an arc.* A beginning, middle, end. The action goes up and down. The tension leads to twists and turns. So, what does the basic story arc look like? Well:   This is an arc. Or, at this point, it’s a line. The beginning of the arc is the beginning of the story. Set the scene: where are we? Who are the characters? …

Arctic Sea Ice Melt May be 2nd Lowest On Record

Wed, 09/18/2019 - 5:14pm

The summer melt of the Arctic sea ice is nearly done and the numbers are flirting with being the 2nd lowest on record. 2012  is the lowest and this year will not be as low but still at alarming levels. The real change is the loss of the multi ice that lasts from year to year. This “old” ice is nearly gone and you can see it disappear in this …

Federal agency moves, vacant science positions create concerns about “brain drain” in the U.S. scientific enterprise

Wed, 09/18/2019 - 2:16pm

Recently, there have been media reports that some federal agencies—namely, the U.S. Geological Survey (USGS), the Bureau of Land Management (BLM), and parts of the U.S. Department of Agriculture (USDA)—are planning to move headquarters science staff far outside the Washington, D.C. area, causing many scientists to choose to leave these agencies rather than relocate. Meanwhile, the National Weather Service (NWS) has left hundreds of scientific positions vacant, putting stress on …

New study suggests gigantic masses in Earth’s mantle untouched for more than 4 billion years

Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth’s crust, offering a window into the building blocks of our planet, according to new research.
