During a 2023 expedition, Dr. John Jamieson & an international team tested this sonar system. This tech transforms the ability to map, explore, classify, & monitor the seafloor in detail, & dramatically reduces the time needed to locate seafloor features. #seafloormapping

Interferometric synthetic aperture sonar images of the seafloor. (a) Wreck of a barge on a sediment substrate with boulders. (b) Offshore energy production infrastructure. (c) Fresh lava flows (pillow basalts, sheet flow with ropy lava texture) from a mid-ocean ridge. (d) Discarded rope next to bedrock outcrop and sand and gravel sediments. Both bedding planes and glacial striations are visible in the outcrop. Image resolution is 3 cm for all images. Data for images a, b, and d were collected using a Kraken Robotics MINSAS 180 system mounted on Kraken’s Katfish towed vehicle. Data for image c was collected using a Kraken Robotics MINSAS 120 mounted on the Schmidt Ocean Institute remotely operated vehicle SuBastian.
