Zombies: A Seismic Defense

A farewell note to a former coworker, inspired by John Rennie at PLOS: As trained geophysicists, we’ve kept the office mercifully zombie-free since the Apocalypse, even maintaining a rigorous field schedule. A global catastrophe of undead hordes roaming the streets … Continue reading

Detecting Physical Properties (Fieldwork)

Geophysical field surveys are used to investigate the subsurface. Geophysics may utilize passive techniques, measuring and mapping changes in the ambient field, or as active techniques that measures how the geological environment responds to an input signal. In either instance, … Continue reading

Physical Properties of Geologic Materials

As Sedimentation Saturday was a lovely way of teaching myself more sedimentation and stratigraphy than I had previously known, for 2014, I’m taking the same route to look at the most fundamental concept in geophysics: the physical properties of geological … Continue reading

Geo-Job: On how to be a Geophysicist

I’ve written before about how I love field geophysics, and find the job to be a mix of James Bond villain meets MacGyver. The post has spawned some questions, with emails to me from proto-geophysicists asking how to get from … Continue reading

Geo’s Sign

This gallery contains 1 photo.

Today, I offer a geosign for the July Accretionary Wedge created by geoscientists and geographers: Geophysical surveys involve a lot of trying to figure out where you took measurements in relation to where you want data. In mountainous, forested, cloudy … Continue reading

Tropical Geophysics: a post-trip report

I not-so-recently returned from not zapping zebras, my first experience with tropical fieldwork for geophysics. Packing List Aside from the usual collection of field gear and the semi-standard collection of tropical-medication, my retroactive absolute must-pack list includes: Acquiring jugs or … Continue reading

Geophysics in the Tropics

I’m packing up for a field stint in the tropics, trying not to zap zebras while imaging the subsurface. While chatting with colleagues over lunch, she advocated for packing evaporated milk to mix with boiling water when consuming antimalarial medication, … Continue reading

Recreational Geophysics (winter edition)

This gallery contains 1 photo.

When hunting for snowshoes in the equipment room, I discovered snowboards and skis. I am now utterly enchanted by the concept of a downhill geophysical survey. If we blend in some techniques from urban skiing in small town British Columbia, … Continue reading

“I have no good explanation for why a geophysical company has so many teddy bears.” Explanations proffered on social media include: Fashionable cushions for high amplitude seismic testing. “Padding”-ton bears to supplement shock-foam when packing shipments. Hug-providers for when data-processing … Continue reading

Geophysics Bunker

This gallery contains 1 photo.

In honour of Halloween, our every-day creepy storeroom decent: You thought I was kidding about geophysicists as supervillains, yet what better location for an urban lair (or final stronghold to defend against the zombie hordes) than a concrete bunker hidden … Continue reading
