7:36 PM | Beating hearts in Denali
“It never ceases to amaze me. No matter what the conditions are, what time of year it is, the place still awes me.” ~ Patricia Owen, wildlife biologist, Denali National Park & Preserve Cold nights have prompted the Denali landscape to turn colors; reds and purples are spectacular tundra accents spread across the wild vista. We’re at Denali National Park & Preserve meeting park rangers and scientists; searching for bears. While park visitor numbers are usually […]

5:19 PM | Mars Exploration Rovers Update: Opportunity Suffers Unwanted Computer Reboots, Hunkers Down for Reformat
After setting the new off-Earth rover distance record in July, Opportunity roved on in August, driving south along the eastern edge of Endeavour Crater's western rim to Wdowiak Ridge on its journey to the next big destination, Marathon Valley.

4:34 PM | Research Shows Dog’s Are Natural Magnet Sensors!
As if dogs aren’t interesting enough, it has now been discovered that dogs have an ability to “read” magnetic fields.  This magnetic field ability produces some interesting repetitive nature, particularly in the area of relieving themselves.  The research found that when the magnetic field was stable, dogs consistently relieved themselves in a North or South […]

4:26 PM | Is My Pet Healthy? Use These Tips!
Most households have either a cat or dog if not both.  They are by far the most favoured household pets to own and for the most part, people don’t just have one.  They become integral parts of the family that are treated to things such as birthday parties, Christmas presents and other luxuries.  It’s no wonder that […]

4:17 PM | Rift valley has formed south of the eruption in Holuhraun lava field
This information is going to get outdated quickly. This is current events in Báðarbunga volcano. Rift valley has formed south of the eruption. Part of this rift valley is not under the glacier. Most of this rift valley … Continue reading →

3:01 PM | Silts and Slope Failures at Discovery Bay
Subtle variation in the geologic units on a bluff can make a big difference in how slopes fail. At this bluff in Discovery Bay, west of Port Townsend, the main driver is erosion at the base of the bluff by wave action. But how the bluff fails is important in terms assessing risk to sites above the slope. A few notes on this view of the bluff. The trees on the slopes above the bare bluff are generally mature Douglas fir. Its a harsh growing environment so most of these trees are […]

11:20 AM | Rugose corals in the Clearville member of the Mahantango Formation
Here are some rugose coral fossils (along with some cross-sectioned articulate brachiopod shells) to be seen in the Clearville member (~80 feet thick) of the Mahantango Formation, exposed on the north side of route 55, just west of the West Virginia / Virginia border. These fossils are cool in their own right (what fossils aren’t?) but here they’re serving another purpose – they’re letting us know where we are in …

11:00 AM | GeoCinema Online: Our changing Climate
Welcome to the third instalment of Geocinema! The focus this week is on climate change and how it impacts on local communities. Sit back, relax and make sure you’ve got a big bucket of popcorn on the go, as this post features a selection of short documentaries as well as trailers of feature length films. […]

An important part of our annual conference is giving students and recent graduates the opportunity to present their work – through a poster and drinks reception at the end of the day. Last year we had some fantastic posters – from both undergraduate and postgraduate students, and recent graduates. This week and next we’ll be […]

5:55 AM | Climate sceptics see a conspiracy in Australia's record breaking heat
You could cut the triumphalism on the climate science denialist blogs right now with a hardback copy of George Orwell’s Nineteen Eighty-Four. Their unbridled joy comes not in the wake of some key research published in the scientific literature but in the fact that a climate sceptic has got a mainstream newspaper to give their conspiracy theory another airing. The sceptic in question is Dr Jennifer Marohasy, a long-time doubter of human-caused climate change whose research at Central […]

4:08 AM | A Perspective on The Accuracy of Meteorologists
This is a guest post by Brad Panovich the Chief Meteorologist at WCNC-TV in Charlotte, NC I know what you are thinking. “Here we go another Meteorologist telling me how great they are”. That is not the purpose of this blog post. I am simply attempting to put what we do in perspective. Plus I’m fascinated by how we perceive certain things about weather forecasting versus other professions we are …

1:30 AM | Leperditia Giant Ostracod Fossil
Here is a picture of a Leperditia ostracod fossil at the Museo di Paleontologia at Sapienza University of Rome Italy. Creatures like this existed in the Silurian Period (about 430 million years ago). Fossil was found in Aminne, Sweden. Image taken in June 2014.

12:50 AM | Submit Predictions to Fly in an Asteroid Time Capsule
You have four weeks left (until September 30, 2014) to submit names to send to an asteroid, and now you can also separately submit space exploration predictions or images to send in a time capsule to and from that same asteroid. Both sets of information will fly etched on microchips on board the NASA OSIRIS-REx spacecraft.

11:19 PM | Here We Go Again: Yellowstone is Going to KILL US ALL! Wait a minute...
I'm going to start with the conclusion (I've highlighted some parts using the bold font):Geological activity at Yellowstone provides no signs that a supereruption will occur in the near future. Indeed, current seismicity, crustal deformation and thermal activity are consistent with the range and magnitude of signals observed historically over the past century [Lowenstern et al., 2006]. Over the past two million years, trends in the volume of eruptions and the magnitude of crustal melting […]

10:53 PM | Reason in a Dark Time
Dale Jamieson is a philosopher long acquainted with the work of climate scientists. His recently published book was begun 25 years ago, “an avocation that became an obsession”. He used to joke when asked why the book wasn’t appearing that he was waiting to see how the story ended. Then it dawned on him after […]

10:05 PM | breakfast junk
One of the signs I'm getting older is that I need to keep a better eye on my diet. Fast food does unpleasant things to my digestion. And I really can't deal with sugary breakfasts anymore. If I have a doughnut or one of those individually-wrapped convenience store pastries, I'll be ok for an hour or so, and then I'll crash and be out of it for the rest of the day.My ideal breakfast for fieldwork has complex carbs and some sort of protein to keep me going through unpleasant weather and long […]

10:01 PM | Small aftershock in Duncan area
A M2.6 earthquake on the Arizona-New Mexico border is likely an aftershock from the June 28, M5.3 Duncan earthquake.  Because of it's small size and the limited seismic station coverage in the area, we suspect the location is not well constrained.     The quake hit at 9:21 a.m. this morning.  We expect aftershocks will continue for weeks to months.  [Right, orange star marks epicenter.

9:49 PM | The Chemistry of Cores
Petrologists identify minerals using tiny slices of the rock called thin sections; geochemists identify the chemical characteristics of these rocks.  Together this information can build a more complete picture of the core.   read more

9:47 PM | Geo 730: September 2, Day 610: Fractured Ceiling
It's not terribly apparent in this photo, but there's a fracture zone/fault running along the ceiling, roughly in the middle of the shot. It's clear that this structure was the one the miners were following initially. The target, I was told by another visitor to this area many years ago, was deposits of "blue-white" clay, which could be rinsed to give tiny amounts of gold dust and wire. The clay deposits were (and in small amounts, still can) found in open spaces within the fractured areas. It […]
