German U-boat Surveyed a Century after Wartime Sinking

A First World War German submarine has been surveyed for the first time since its loss in 1917. Sophisticated scanning techniques and deep-sea video footage have revealed a large hole in the boat’s hull – caused by an attacking British naval vessel. During the summer of 2020, scientists led by deep sea archaeological expert Dr Rodrigo Pacheco-Ruiz of the University of Southampton, in collaboration with offshore survey companies MMT and Reach Subsea, investigated the wreck of UC-47 on behalf of Tolmount Development during offshore operations to prepare for the laying of a new pipeline in the North Sea, some 20...

Fugro Begins Extensive Site Characterization for ScottishPower Renewables’ East Anglia Hub

Fugro has begun the geophysical survey phase of a large multidisciplinary site investigation contract worth around GBP55 million for ScottishPower Renewables’ (SPR’s) East Anglia Hub project. The phased site investigations are scheduled to finish at the end of 2021 and support the development of wind farms in the UK southern North Sea over an area of more than 800 square kilometres. The results from Fugro’s site characterization will feed into SPR’s ground models for the East Anglia Hub and support seabed mobility assessment, foundation design and cable-route engineering. Operating from dedicated geophysical survey vessels, the Fugro team began the UXO... (read more)

Beagle Gulf Hydrographic Survey in Full Swing

Precision Hydrographic Services (PHS) has recently been contracted by the Australian Hydrographic Office (AHO) to undertake a hydrographic survey in Beagle Gulf, located in the Northern Territory of Australia, to determine the local bathymetry for navigational purposes. The hydrographic survey is taking place between the beginning of July 2020 and the end of August 2020, with two survey vessels, the Limitless and PHS Zephyr, both displaying flags (India over Romeo – conducting survey operations) while undertaking survey. The survey will be measuring oceanographic parameters including currents, tides and wave height in the immediate area, with oceanographic measurements recorded by utilizing... (read more)

Using New Acoustic Technology to Help Conserve the Southern Ocean Ecosystem

As fisheries are starting to harvest krill resources to feed the world’s population, this must be done in a sustainable manner, based on accurate, scientific observations. Scientists at NOAA in the USA are now using sophisticated new acoustic technology to truly “see” krill in the Southern Ocean. How will this scientific research help conserve the Southern Ocean ecosystem? Today, one-third of commercially important marine fish stocks in the ocean are suffering from the effects of overfishing. As krill is becoming an important supplement for fisheries looking to harvest new resources, sustainable management of krill fisheries has come to the fore.... (read more)

Sea-level Charting Satellite Passes with Flying Colours

The Copernicus Sentinel-6 Michael Freilich satellite has been put through a series of strenuous tests leaving the eyes of the teams involved in this international mission set firmly on its final results. Happily, Sentinel-6 has passed with flying colours and engineers can now prepare it for shipment to the US for liftoff on a SpaceX Falcon-9, which is scheduled for 10 November. Renamed in honour of Michael H. Freilich, who led NASA’s work in Earth science, Copernicus Sentinel-6 Michael Freilich will take over the critical role of monitoring sea-level change by extending the long-term measurement record of global sea level...

Submerged Munitions, No Hazard Left Undetected

Minimum Requirements for Munitions Detection at Sea
Munitions in the sea pose a risk to the sustainable development of the ocean economy. In particular, they remain a global challenge during the construction of wind parks, pipelines and other infrastructure. To ensure high-quality performance during the execution of the necessary maritime munitions detection and clearance operations, industry experts and scientists from Germany have defined a set of requirements. These are particularly important in the detection phase which requires the attention of hydrographical surveyors. Safe access to large areas of the seafloor is a prerequisite for offshore economic development. However, this ability has been compromised by the presence of... (read more)

Mapping Submarine Groundwater Discharge with Thermal Infrared Imaging

Using Cutting-edge Technology and High-resolution UAS
Submarine groundwater discharge (SGD) is a significant part of the water cycle that delivers anthropogenically derived and naturally occurring nutrients to coastal waters. As part of the drive to develop methods to prevent the degradation of coastal water quality, research conducted at the University of North Carolina Wilmington attempts to address the ambiguity associated with SGD point source locations. This case study outlines how cutting-edge high-resolution unmanned aerial system (UAS) thermal infrared (TIR) imaging methods have been coupled with the newest technology for continuous and autonomous SGD monitoring. Submarine groundwater discharge – the process in which groundwater flows down-gradient through... (read more)

Mariscope Unveils Rescue and Support ROV with Full Integration

Mariscope Meerestechnik has added another new model to its fleet. The Commander MK III Rescue is an ROV with features that stand out in a vehicle of this class. This ROV serves as an example of how Mariscope customizes a model and executes system integration, according to the specific needs of its clients. The first Commander MK III Rescue vehicle has been installed on board the shadow boat HODOR as the rescue unit for the SEAmagine Aurora 3 manned submarine, which this vessel carries and operates. Like the Aurora, this ROV has a working depth of 1,000 metres, thus guaranteeing support... (read more)

Subsea Autonomy is Moving Beyond Waypoints

Underwater an AUV Must Rely Upon its Own Sensor Network
The AUV has been the tool of choice for shallow-water MCM and EOD operations for a number of years. The coverage by popular news channels of unfortunate events, such as the MH370 tragedy, has also shown that the AUV has undisputedly become the tool of choice to carry out salvage operations at extreme depths. The AUV has no physical link to the surface and the majority of missions are still pre-programmed by a human, which can be time consuming and error prone. Missions are normally a sequence of defined waypoints where the AUV may be required to carry out certain... (read more)
