GeoAI is revolutionizing GNSS-based heighting by enhancing geoid models, allowing for more precise transformations from ellipsoidal to orthometric heights. This optimization results in more accurate height measurements, crucial for a wide range of applications. By leveraging GNSS-based heighting, organizations can achieve unparalleled precision and efficiency in elevation measurement, surpassing traditional surveying methods with centimeter-level accuracy. This technology proves particularly valuable in areas lacking extensive height reference infrastructure, enabling accurate and efficient elevation measurements over large distances, especially when coupled with precise geoid information. The impact of GeoAI on traditional surveying methods is profound, enhancing both accuracy and efficiency by optimizing geoid models for precise height measurements. This advancement streamlines data analysis and accelerates surveying processes, ensuring reliability and avoiding data reduction discrepancies, especially in joint surveys involving nearshore and offshore geophysical surveying. #GeoAI #GNSS #GeoidModels #ElevationMeasurement #SurveyingTechnology

The Role of Inertial Navigation Systems (INS) in Offshore Surveys The vast expanse of our oceans remains largely uncharted, with only about 15% of the global ocean floor mapped by modern survey systems. For offshore industries, understanding the seabed topography is essential. Whether it’s locating oil and gas deposits, ensuring pipeline routes are obstacle-free, or maintaining stable positions near offshore platforms, precise positioning is paramount. Inertial Navigation Systems (INS) Explained An INS calculates an object’s position, orientation, and velocity without relying on GPS technology. It’s like having an internal compass and gyroscope for marine vessels. INS devices use accelerometers and gyroscopes to measure motion and rotation, providing critical data for navigation. Let’s dive into how INS works and its key components: Sensors in an INS: Accelerometers and Gyroscopes: INS devices use accelerometers and gyroscopes as motion and rotation sensors. These constitute the Inertial Measurement Unit (IMU) and may sometimes include magnetometers. These sensors communicate with a computer unit, which translates their data into actionable controls. Together, they offer accurate information for position changes. Accelerometers: these measure changes in linear velocity, while gyroscopes measure rotational velocity. Typically, three accelerometers and three gyroscopes are used, aligned orthogonally to cover all three dimensions of movement. Dead Reckoning System: INS operates on a dead reckoning system. Initially, an external source (such as a GPS receiver or operator) provides the object’s starting position, velocity, and orientation. As the object moves, the INS continuously calculates and updates its position, velocity, and other motion elements using data from motion sensors. The following INS equipment like iXblue Pty Ltd, Survey Specialists Octans Nano, Rovins, SPAN technology from Hexagon AB | NovAtel, Ellipse-D which is The Smallest RTK INS from WASSP are revolutionizing the detection and calculation of motion, position and rotation information in offshore surveys.

Join us on the 21st of August on an upcoming SUT - Society for Underwater Technology webinar where we discuss the #geohazards and #engineering #challenges associated with the complex infill of tunnel valleys. These valleys, formed by #subglacial processes, contain highly heterogeneous #sediments ranging from fine clay to #boulders, sometimes with shallow gas. The varying geotechnical properties of these sediments, identified through ultra-high-resolution #seismic #data and detailed analyses, present significant challenges for #marine engineering and development projects. #offshorewind #offshore #geoengineering #subseaengineering #underwatertechnology #subsea #marinetechnology #marineengineering #geotechnics #robotics #ai

The Indo-Pacific region is vast and geologically complex, so it is no surprise that in almost 30 years of seismic operations, PGS has set many industry ‘firsts’ along the way. Several world record streamer spreads, the most square kilometres of acquisition per day (2008), the most square kilometres of acquisition per month (2008), the first commercial deployment of our multisensor GeoStreamer (2008), the first commercial deployment of the multi-level source concept (2010), the first multi-azimuth (MAZ) GeoStreamer survey (2013), the only commercial compressive sensing imaging (CSI) in multiple countries (2015-2017), the first ‘negative offset’ towing of sources behind streamer fronts (2019), and many more. It takes courage and initiative from our customers to work with us on these pioneering efforts, and more often than not, they make the ‘light bulb moment’ to take our technology to their next frontier. It also requires significant investments and faith from our operators teams, our survey planning teams, and the people doing the physical work on the vessels. The Ramform Sovereign (pictured) was the first PGS vessel to receive our proprietary and industry-leading ‘GeoStreamer Inline Acoustics’ (GIA) modules for a full spread, our eBird depth and steering control devices, our source control and management platform able to independently communicate air, telemetry and data to each individual air gun (thereby making CSI and eSeismic acquisition possible), and throughout all these step changes, rarely skipped a beat.

Getting ready for another couple of weeks out in the field with Big Rock Exploration geologists mapping and sampling out in Wyoming for Relevant Gold Corp (TSXV:RGC) (OTCQB:RGCCF). Have printed out multiple copies of 40 field mapping sheets at 1:5,000 scale (as one can see in the photo below) that include a transparent 1-meter lidar hillshade image overlain by 5-meter spaced contour lines, previously collected and assayed rock samples, mapped shear zones, and mapped and compiled outcrops (1:10,000 to 1:24,000 scales). Detailed geologic mapping on such field maps are the foundation upon which discoveries are built. Cheers to all.....

Multibeam sonar is a type of active sonar system used to map the shape of the seafloor, coastline and other physical features. Multibeam sonar sends out multiple, simultaneous sound waves to cover the space directly underneath and out to each side of the ship towing the survey equipment. #OceanMonthNOAA #Hydrography #UnderwaterSurvey #OilandGas #Multibeam
