Dual-head Mapping
A dual-mount multibeam sonar installation is used to conduct extreme shallow-water surveys of intertidal seafloor to track morphologic change. This article contributed to by Heather Weiner, Brent von Twistern, Mike Brissette, Jonathan Beaudoin, and Amanda Hacking. The intertidal and nearshore zone is among the most ecologically productive and important zones to coastal resource management agencies. However,...
UAS: It’s Unstoppable and Headed Your Way
From time to time I like to stop and think about the mission of Pangaea and explain that mission to you. My task is exposing you to new, emerging geospatial technologies. But why bother? Here’s a little analogy I thought of to help explain why keeping abreast of new geospatial tech is critical. Imagine emerging...
The Future of Treasure Hunting: Part One
We continue this series on treasure hunting with geospatial tools by taking a peek at what the future may hold for seekers of undersea hidden treasure. The tale of Mel Fisher and his hunt for the “Nuestra Senora de Atocha” illustrates the difficulties of undersea treasure hunting. The Atocha was the most famous ship of...
Underwater Drones Search for Czar’s Lost Treasure
Continuing with our series (part one and part two) on the role that geospatial technology plays in treasure hunting, we come to the mysterious tale of the RMS Republic. Launched in 1903, the Republic was a part of the White Star Line, and, foreshadowing its sister-ship the Titanic, it sank six years later, 50 miles...
Outlook 2016: 40 Under 40

It is our wish that these profiles will honor those who work tirelessly to promote geospatial fields and to provide inspiration for young people considering...
Aqua Bots
Above: The Z-Boat 1800 on a riverine hydrographic survey using sidescan sonar. Unmanned & Unlimited Unmanned aerial systems (UAS) get the lion’s share of media coverage, which is just not fair. Hardworking unmanned marine platforms, both surface and subsurface, have a lot to offer in the hydrographic surveying and inspection space. As a big bonus...
