I am now a “famous palaeontologist” … thanks to my antlers

Just over a year ago, in his write-up of the Edinburgh SVPCA, Matt included a photo of me standing in front of a Giant Irish Elk (Megaloceros), positioned so that the antlers seem to be growing out of my head. Matt finished his post with a background-free version of that photo, and commented:

Geophysical Surveys on Glaciers

To The Poles | 1 October, 2014
Yesterday, I took a group of enthusiastic third year geologists and environmental scientists to the British Geological Survey in Keyworth for a tour of the facilities and discussion/demonstration of their geophysical equipment. The BGS staff did a fantastic job of entertaining and educating us all - thanks BGS! - and this post primarily provides back-up notes and further information about the geophysical surveying techniques we saw - with a cryosphere twist!

Environmental Management Centre Research Group

G-Soil | 1 October, 2014
The Environmental Management Centre (EMC) was founded in 2013 at Mykolas Romeris University, Vilnius, Lithuania. The group is composed by young and proactive researchers from the entire world. The centre has an interdisplinary vision of science and aims to connect environmental, sociological and economical questions, in order to understand environmental questions from a wide perspective. The areas of research of the centre are, land use management and territorial planning, environmental economics, sustainable development, climate change and urban environment. The EMC members have experienced in the organization of international events as the 4th International Meeting of Fire Effects on Soil Properties (FESP4) and in European Geoscience Union Assembly and work with other scientific groups.

"I knew it all along..." - avoiding hindsight bias after eruptions

NonSolidGround | 1 October, 2014
"I knew it all along..." - as volcanologists, we need to be careful not to fall into the many traps that come from retrospectively looking at and indeed commenting on crises or catastrophes such as the recent eruption of Ontake.

Whitney Glacier Retreat and Thinning, Mount Shasta, California

From a Glaciers Perspective | 30 September, 2014
A UCSC study looking at the change in the glaciers from 1944 to 2003 noted an expansion of the Mount Shasta glaciers that when published in 2008 was in contrast to most alpine glaciers globally or in the Pacific Northwest. Tulaczyk and Howat (2008) noted that Whitney Glacier had advanced 850 m since 1951 to 2003, but when did retreat begin? There was a period of advance for many Cascade volcanoes glaciers between 1950 and 1980, but retreat after. For example on Mount Baker all of the glaciers advanced during the 1944-1979 period by an average of 480 m (Pelto and Hedulund, 2001). By 2010 Pelto and Brown (2012) observed all were retreating with an average retreat of 370 m. In 2003 all of them all had retreated , but many were in advance of their 1944 position. By 2014 the retreat has exceeded the advance from 1944 on most Mount Baker glaciers, more on this in the next post. This is an important point for Mount Shasta too, Whitney Glacier was advancing in 2003 but had been retreating in the late 1980's and 1990's. Whitney Glacier was further advanced than in 1944, but how short lived was the advance? Here we examine satellite images from 1987 to 2014 to identify recent trends, along with Google Earth imagery of termini of several glaciers and the 1981 USGS observations.

Geo 730: September 30, Day 638: Cobble Beach

Outside the Interzone | 30 September, 2014
I've already covered Yaquina Head to an extent in this series (See The Index, and scroll down to Yaquina Head, at the bottom), so for this segment of this particular trip back in July, I had intended to focus pretty much exclusively on observations and features I haven't discussed and shown earlier. However, in yesterday's post, I mentioned the cobble beach here, so I decided I should show a companion photo to illustrate my point.

Making Sense of Climate Science Denial MOOC

Dr. Keah Schuenemann's Blog | 30 September, 2014
I'm a big fan of signing up for MOOCs (Massively Open Online Courses)!  These days you can learn so many things online, for free!  This isn't meant so much as a substitute for college, but a supplement for people of any age who are just looking to learn more about a topic.  For example, I took differential equations 12 years ago, but I could brush up on my skills using a MOOC.  I could also learn how to program, how to be a better teacher, how to solve the climate crisis using engineering, etc.

Bandits and Henchmen

Stories in Stone | 30 September, 2014
A group of bandits and henchmen invaded our yard today. Their appearance is an annual event, at least for the bandits, who tend to arrive in early autumn, hang out for 10-20 minutes and then leave. In contrast, I can see the henchmen year round. Of course, I am not writing about people, but about birds. The bandits are cedar waxwings, a gray brown bird with a sporty, almost mohawk crest. A black mask covers their eyes giving them their nefarious appearance. The henchmen are dark-eyed juncos, in particular the Oregon form with their conspicuous black hoods and handsome little pink bills.

Urban Tumbleweeds -- free & hardly lonely

Tumbleweeds are integral to our beloved American West -- a land of wide open spaces where tumbleweeds, cowboys and other free spirits can go wherever the wind takes them.  They symbolize the revered rugged individualist -- loyal only to his own personal code.

Not picking parameters

Agile Geoscience | 30 September, 2014
I like socks. Bright ones. I've liked bright socks since Grade 6. They were the only visible garment not governed by school uniform, or at least not enforced, and I think that was probably the start of it. The tough boys wore white socks, and I wore odd red and green socks. These days, my favourites are Cole & Parker, and the only problem is: how to choose?
