The Impact of Climate Change on Coastal Communities | GEOTalks Ep. 7

• About this episode • Storm surges and sea level rise pose greater risks to coasts each year. Maine felt the effects of climate change this past winter when powerful storms and flooding berated its coast. The Camp Ellis Jetty was particularly vulnerable to these storm surges and sea level rise, and the Saco Bay community lost nearly 40 homes as a result. In this episode, we spoke with Dr. Will Kochtitzky who is leveraging GIS technology, lidar, and photogrammetry to study the effects of sea-level rise on the Camp Ellis Jetty in Maine. The concepts in this episode align with what Florida, North Carolina, and other southern states are experiencing in the wake of Hurricane Helene and Hurricane Milton. This episode was recorded before the storms, which devastated communities in September and October. We hope that these communities recover soon and heal from this disaster. • Listen on-the-go • Youtube: https://youtu.be/bzucCiygHIw Spotify: https://open.spotify.com/episode/3xYBbOLnCqut4WkwS67Gqz?si=6d18e76d53554a91 Apple Podcasts: https://podcasts.apple.com/us/podcast/the-impact-of-climate-change-on-coastal/id1734675688?i=1000673329108 • Read the Article • Article: https://www.bluemarblegeo.com/blog/impact-of-climate-change-on-coastal-communities/ • Timestamps • [00:00] – Intro [00:53] – Introducing Dr. Will Kochtitzky [01:10] – Glaciers & sea level rise [04:41] – About Dr. Kochtitzky [07:44] – Responding to the community’s needs [08:39] – Dr. Kochtitzky’s research (drones and more!)

Global Mapper’s Origin | GEOTalks Ep. 5

You may know the Global Mapper software suite, but do you know how it was created? Mike Childs created Global Mapper — known then as dlgv32 — as an intern at the USGS in 1997. This version had a fraction of the power of the Global Mapper we know today, however, it boasted great GIS mapping functionality for the time. Mike Childs joined the GEOTalks team to unpack Global Mapper’s origin story and discuss what’s made it such a fulfilling project to develop. Blue Marble Geographics CEO and President, Patrick Cunningham, joins us as a special co-host to share his perspective of Global Mapper’s origins and Mike’s impact on the company over the years.

Accessible Bathymetric Data & Its Impact on Marine Conservation in the Beqa Lagoon | GEOTalks Ep. 4

Bathymetric surveys provide vital information that informs decisions about marine environments and communities. Tomer Ketter of Map the Gaps and SubMerge, and Sefano M Katz of the Pacific Blue Foundation’s Beqa Lagoon Initiative, joined us on this episode of GEOTalks to share insights from a collaborative bathymetric survey they performed in the Beqa Lagoon in Fiji. The livelihood of Fiji’s people is tied to its land, waters, and the diverse ecosystem that thrives there. In the episode, they explored the impact of accessible bathymetric data on marine conservation, social equity, and cultural integrity in Fiji.

Tracking Forever Chemicals (PFAS) with GIS Technology featuring Katrina Schweikert | GEOTalks Ep. 2

About this Episode Per- and polyfluoroalkyl substances (PFAS) are a family of chemicals defined by carbon-fluorine bonds that make them resistant to fire, water, and oil. When PFAS were discovered in our farmlands and waterways, studies indicated that these chemicals have adverse, long-term effects on our environment and bioaccumulative effects in humans and other organisms. A team from the University of Maine at Orono, led by Dr. Torsten Hahmann, is developing a solution to track nationwide PFAS contamination. Katrina Schweikert joins us on this month’s episode to share her work on the Safe Agricultural Products and Water Graph (SAWGraph). This geospatial knowledge graph will be used in efforts to understand and mitigate the PFAS contamination in our agricultural products and waterways.
