200-m contours are shown in thin black, 100-m contours are shown in bold black, to highlight the pools, and 20-m contours are shown in bold red. Here, a regional bathymetry map shows the three major depressions within Challenger Deep – the Eastern, Central, and Western Pools. She put in 17 to 18 hours most days and kept Globie at the helm of the sonar system monitor. Dawn gave Globie to Rochelle to show appreciation for her work during the expedition. This image shows Globie, the Esri mascot, in front of the sonar monitor. Onboard the ship, mapping is done with the Kongsberg EM-124 sonar system. Onboard! Let the Mapping Begin: Photo courtesy of Dawn Wright. New data from this expedition is being submitted to Seabed 2030 and ArcGIS Living Atlas of the World, the foremost collection of geographic information from around the globe. She also prepared planning maps for the submersible dives and instrument deployments. Rochelle was responsible for processing and mapping the bathymetric data collected by the ship’s sonar. They proudly hold the Seabed 2030 (a UN program dedicated to mapping the global seafloor in detail by 2030) flag before the expedition. Here, Dawn, on left, is standing at the port in Guam with Rochelle Wigley of Map the Gaps and the University of New Hampshire. The expedition began in Guam, where Dawn boarded the DSSV Pressure Drop, a vessel owned by ocean research and exploration company Caladan Oceanic, to journey to Challenger Deep. Here are 30 photos from her expedition, including images from Challenger Deep, 10,919 meters below the surface, maps from the expedition, and scenes taken within the sub. Her mission? To use high-resolution sonar to map a part of our planet in never-before-seen detail. On JEsri Chief Scientist, Dawn Wright, made history as she dove in a submersible to the deepest place on Earth, Challenger Deep. Written by Victoria Phillips and Dawn Wright.
