QPS Client Spotlight: Ocean Exploration Trust
The Ocean Exploration Trust is a 501(c)(3) non-profit organization founded in 2008 by Dr. Robert Ballard with three overarching goals: (1) Exploration of the world’s oceans to better understand the geological, biological, chemical, physical, and historical aspects of our planet; (2) Innovation of new advanced technologies to make exploration more efficient and more effective than ever before; and, (3) Education of the next generation of leaders in science, technology, engineering, and math, by using the excitement of exploration to inspire and motivate learners of all ages. To address these goals, the Trust undertakes annual expeditions on board its Exploration Vessel Nautilus using advanced robotic and telepresence technologies, and streams the exploration live to the internet, schools, after-school programs, museums, aquariums, and science centers to complement a growing program in community-based STEM education.

How Ocean Exploration Trust uses QPS software
The Ocean Exploration Trust uses Fledermaus software to support its science, operations, education, and telepresence missions. Nautilus is equipped with an EM302 multibeam sonar and Knudsen sub-bottom profiler. Wherever the ship sails, we map the seafloor, both opportunistically as we transit from one site to the next, and to survey a particular area of interest to identify remotely operated vehicle (ROV) dive sites. The Fledermaus software package allows us to visualize the data and create products for many needs.
In our exploration, the rapid analysis of data is important to make informed decisions about dive sites. Digital elevations models, often draped with the backscatter data or with added water column features, are used by scientists to identify areas of interest. Scientists will choose areas with unusual geological features, hydrocarbon plumes and seeps, or other features of interest and use Fledermaus to pick out waypoints for ROV navigation. The FM Midwater detection tools were particularly helpful in identifying new seeps in several recent cruises, including off the coast of southern California in August 2015. Scientists were able to map an area and rapidly identify the source location of the seep for an ROV dive, and along with three other new seep discoveries on this cruise suggests that methane seepage is wider spread in the region than previously thought.
The navigation and data teams, often mostly undergraduate students learning Fledermaus for the first time, create base maps with contours for our navigation software and export KMLs of the bathymetry to share with scientists on shore. The science watchstanders will sometimes use the real-time feed of ship and ROV positions within a Fledermaus scene to track and direct the dive progress. This 3D feed is sent out over our Nautilus Live website providing the public and scientists on shore with a geographic and bathymetric context for the ROV location. Having the ability to fly around the dive site enhances our outreach efforts as the Watch Lead can use this feature to periodically provide a “tour” of the dive site for the Nautilus Live viewers, while explaining the geological history and dive objectives.
The video-making functionality is another effective outreach tool. After we map an area, we are able to create fly-throughs that synthesize all of our data products including sub-bottom and water column data to allow scientists to piece together an understanding of the geology of an area or to share with a public audience for learning purposes. For example, we had an Artist at Sea, whose work is inspired by multibeam bathymetric data, sail on board Nautilus in July. She projected the wire-mesh grid surface of the volcanoes and canyons we mapped onto a canvas to guide her painting. She also worked on creating a video fly-through from the areas we mapped to complement her future exhibit.
OET is looking at incorporating QPS’s latest software, Qimera, into its standard procedures to improve sonar data processing.
"We used Qimera on a mapping transit from the Galapagos Islands to San Diego and were excited about its seamless functionality. The intuitive user interface of Qimera will allow us to quickly train interns, who have a wide variety of educational backgrounds and abilities, to process sonar data and create mission-critical data products."

QINSy & Qimera Onboard "Investigator"
Parks Canada returned to the Arctic in the summer of 2015 to continue unraveling the mysteries surrounding the 1845 Franklin Expedition. With the support of many partners the Parks Canada Underwater Archaeology Team resumed its work.
One team continued the archaeological investigation of the wreck of HMS Erebus, and efforts were productive and successful.
A second team, including the Survey Vessel “Investigator” outfitted with QPS QINSy and Qimera and R2Sonic's Multibeam Echosounder Sonic 2024-UHR continued to search for HMS Terror and, after two weeks of intensive work, the location remains a mystery. However, thanks to this mission, improvements were made in the areas of marine security, navigation, and search and rescue in the Canadian North.
About Parks Canada
Parks Canada protects and manages nationally significant examples of this country's natural and cultural heritage, and fosters public understanding, appreciation and enjoyment in ways that ensure their ecological and commemorative integrity for present and future generations. As an international leader in underwater archaeology, Parks Canada is well positioned to showcase how new technologies can be used to locate and analyze shipwrecks to bring part of the story of the Franklin Expedition to life. In 1992, Canada designated the location of Franklin's ships, HMS Erebus and HMS Terror, as a national historic site.
