@JayTCullen I'll include the not-so-good photo of the spider itself to help with the identification.

It was a pleasure to work with the incredible Jalal Norooz Oliaee & Chase Sun from the Metrology Research Centre @NRC_CNRC. We used their in-house developed sensors to measure & map natural sources of #methane. Jalal makes final preparations before a day of surveying. @GSC_CGC.

Just wrapped up fieldwork investigating CH4 release in the western Arctic with colleagues: @PeterfrostMorse, @leximollica, @claudiawood130, @JackieGoordial & Jalal & Chase from @NRC_CNRC. It was so nice to finally work with everyone in person. Here Peter takes notes at a #pingo.

The Victoria #orienteering club will be promoting map and physical literacy through a series of mini electronically timed races at the @PISEworld Festival. Come on out today btwn 11-3. How fast can your kids get through this course? More info: https://t.co/sYbGtR6WS3

@earthquakeguy @ForgeRat @knittingknots @schaefferaj @SediAlex Just over 100 km away there is evidence of past landslides along the edge of the Beaufort shelf. Although these slopes are identified as stable, an earthquake would potentially be a mechanism for failure given the presence of the shallow gas. https://t.co/kjVmvLBIyK

@JayTCullen @instructables @mcindoe @_david_ho_ With a few mods you could also make it your Halloween decoration: https://t.co/48VxnWrnE5

@schaefferaj Ugh. We're all stuck at our home offices and you're out there. So jealous. Looks awesome. Nice videos.

Thought it would be interesting to see what the #wildfire smoke from the US west coast looks like from space using #MODIS imagery. #VancouverIsland begins to get shrouded in smoke on September 12th.

@slimschadey161 Water bombers are working tirelessly to halt the growing fire.

[Roger MacLeod @Roger_MacLeod]

@schaefferaj Yes, it's just a matter of making the switch. The more I use QGIS the more I like it. 🤓

[Roger MacLeod @Roger_MacLeod]

@JayTCullen From the same location...an equally spectacular view of a #flower . Not sure but it might be a red columbine.

[Roger MacLeod @Roger_MacLeod]

@schaefferaj Captured it with my #raspishakeq using the new #ShakeNet app.

[Roger MacLeod @Roger_MacLeod]

@schaefferaj @earthquakeguy @raspishake @LisaNykolaishen @alisonlbird @faulty_data Good for you. Disappointingly not so successful on mine. Far too much noise.

[Roger MacLeod @Roger_MacLeod]

@alisonlbird Same issue for us. Try adding two kids and a College student all on Skype or Zoom at once. I had to order an upgrade to our plan yesterday.

[Roger MacLeod @Roger_MacLeod]

We just had our #ShakeOutBC drill and had 95% participation. How did your office do? Did you Drop, Cover, and Hold On? Be prepared for the real thing with these online resources: https://t.co/r0t92Pr7Hq

Happy #InternationalDogDay
Also a great day to update the pet supplies in your emergency kit - food, water, treats, bowl, can-opener, and anything else that your pet might need.

Earthquake research (including studies of past and present earthquakes) provides the key input for earthquake hazard models. In #Canada, earthquake hazard has been used in national building codes since 1953 (updated in 1970, 1985, 2005 and 2015).

Take a look at #thenarwhal article on the threat of thawing #permafrost on #Tuktoyaktuk. https://t.co/qWiUZRMxTK. The article mentions the work of fellow #GSC colleague @DustinWhalen. Includes some of my #UAV photos.
