One of the goals of our 40 under 40 initiative is to profile stories that could inspire young folks considering entering our fields, and what we heard from hydrographic surveyors is that many of the...
Hydro Insights, Part 2
Reviving Interest in the Seas Pictured: The adventures of Jacques Cousteau, his research vessel the Calypso, and his soucoupe plongeante (diving saucer, aka “Denise”) that he co-designed in 1959 captured the imaginations of generations. Editor’s Note: xyHt is honored to feature insights from these two distinguished scientists in the fields of hydrography, marine surveying, and...
A Shore Thing
Integrity monitoring the islands of the Hampton Roads Bridge Tunnel involves combining hydrographic survey, lidar, shoreline survey, and terrestrial lidar survey. Rigorous structural integrity monitoring to extend the lifespan of critical infrastructure is an economic necessity. Remote sensing and integrated remote sensing provide new ways to monitor all elements of a structure in fine detail....
