Cruise Report: Mid-Atlantic Ridge 44N August-September 2017
MetadataVis full innførsel
This cruise is a result of successful collaboration between NTNU Ocean pilot project Deep Sea Mining and Ocean Infinity, ocean exploration company. It took place at the Northern part of Mid-Atlantic ridge in August - September 2017. From the board of Seabed Constructor, a multi-purpose offshore vessel, a total area of 20 km by 0.6 km was surveyed with the use of an autonomous underwater vehicle (AUV). Along with AUV data, we collected two rock samples and video footage from the axial volcanic ridge (AVR) using a remotely operated vehicle (ROV). Cruise objectives were: - Collect data and samples from the mid-ocean ridge rift valley; - Test new technology: multiple AUV survey; - Knowledge and experience exchange: learn more about technological advances in the industry and their approaches for future collaborations in similar kinds of operations. The data acquired during the cruise include high-resolution bathymetry; acoustic backscatter images; sub-bottom profiler cross-sections; magnetic field measurements (3 components); water column measurements (temperature, conductivity, sound velocity, and hydrostatic pressure). PhD and postdoc candidates of Deep Sea Mining pilot at NTNU will use these data for their research.
