Episode 13 with John Norman 900 450 Nowhere Podcast

Our guest in this episode is John Norman, Director of Strategic Research and Development at Teren, in Lakewood, Colorado. Today, we’ll be talking about wildfire reclamation and the role of geospatial technology in this work.

The 2022 Hermits Peak fire in New Mexico was the biggest in the state’s history, and 60% of its coverage was on private land. Private land owners in this area vary greatly, from those who live off the land by cutting firewood, to those who have a secondary home there. These socioeconomic conditions make this fire one of the most unusual that John has worked on.

Because of the history and private ownership of the affected areas in Hermits Peak, there were thousands of individuals that needed to be contacted so the federal government could start the reclamation process. This was especially difficult because many people in the area do not use technology or are very skeptical of the government.

While also using publicly available terrain and satellite imagery, John and his team were rapidly flying LiDAR and 4-band imagery over the burned area. This process impressively only took about a week, despite covering around 600,000 acres. They were even able to analyze individual trees with the data they acquired.

These fires are occurring more often, so John believes that task forces will be established to immediately come in with technology to quantify exactly what areas are the most at risk. He also hopes to see geospatial technology used to mitigate risks in areas that are prone to fires before they even happen.

Episode 11 – Fossil Hunting

Episode 11 – Fossil Hunting 900 450 Nowhere Podcast

We’ve got three guests in today’s episode: Dr. Caleb Brown, Curator of Dinosaur Systematics & Evolution at the Royal Tyrrell Museum; Dr. Derek Peddle, Professor of Geography at The University of Lethbridge; and Sean Herridge-Berry, a master’s student at the University of Lethbridge, join us to discuss how modern technology is being used to explore ancient fossil beds.

Alberta is known for being a hotbed for fossils, but why? Alberta’s rocks are the right age to preserve fossils, but these rocks have eroded at a quick rate in the badlands of Alberta. These abundant fossils are being uncovered at a high rate, which means this landscape provides a lot of information about fossils.

The standard method of prospecting to find new fossils is pretty low tech: put your boots on, get outside, and keep your eyes on the ground. Generally, fossils look like any other bone. The hardest part is figuring out which fossils are most important.

An interesting fact about fossils is that they are a breeding ground for lichen, a composite organism. There is a bright orange lichen which grows on the fossils, and this orange glow can be used to identify fossils. Furthermore, fossilized material and lichen reflect the sunlight in a certain way, and Sean is currently studying how to use that to identify them in a remotely sensed image.

This technology opens the door to discovering new, yet to be discovered bone beds (layers of rock with concentrated fossils). Watching million-year-old fossils collide with new technology is really interesting and will lead to even more exciting dinosaur bone finds down the road.
