The MetOcean Solutions wave buoy moored in the Southern Ocean recorded a massive 23.8 m wave.
The significant wave height is the WMO standard value to characterise a sea state – approximately the average of the highest third of the measured waves. During this storm, the significant wave height reached 14.9 m. This is also a record for the Southern Ocean but falls short of the 19 m world record buoy measurement that was recorded in the North Atlantic during 2013.
The Campbell Island Wave Rider Buoy was moored on 2 March 2018 at Campbell Island, New Zealand’s southernmost estate and an ideal spot to sample the complex directional wave spectra from the Southern Ocean.
The Southern Ocean wave studies are a collaborative project with New Zealand Defence Force, Defence Technology Agency and Spoondrift. As part of that program, MetOcean Solutions has deployed seven instruments to collect wave data, using one moored and six drifting buoys. All data are freely available to the scientific community and can be viewed in real time. For further information and data access see www.metocean.co.nz/southern-ocean/ or contact [email protected].
A global leader in the provision of low logistic Autonomous Underwater Vehicles (AUVs), Teledyne Gavia announces that it has recently delivered Teledyne Blueview MB2250 modules and associated Teledyne PDS software for all Gavia AUVs operated by the Turkish Navy Mine Countermeasures Command in Erdek, Turkey. The Blueview MB2250 will be used in conjunction with the existing Edgetch 2205 Side Scan Sonars that are currently installed on the Turkish Navy Gavia vehicles and will provide capabilities for side scan sonar nadir gapfill as well as providing high frequency multibeam data that can aid in detection and classification of mine like objects.
During recent Mine Countermeasures (MCM) trials, use of the Teledyne BlueView MB2250 allowed the Gavia AUV to cover roughly forty percent more area in a given time than the vehicle would have been able to cover without the use of gap fill. This greatly increased coverage area is a significant development for small AUVs. The Turkish Navy MCM command will utilize their Blueview equipped Gavia AUVs either from vessels of opportunity or from their AYDIN or ENGIN Class minehunters to augment existing MCM capabilities.
The Gavia AUV is an autonomous sensor platform that is user configurable by the addition of one or more sensor, navigation or battery modules by means of a unique twist lock system. The Gavia AUV is a fully low logistics modular system designed for operation from vessels of opportunity and has the greatest depth rating of any vehicle in its class. The modular design of the Gavia ensures maximum mission flexibility and system upgradability. Module options include acoustic payloads for ASW training, various side scan sonars, multibeams, camera, and an array of environmental sensors.

A unique new probe that combines the power of the SWiFT SVP and a turbidity sensor has been launched by leading British oceanographic and hydrographic instrument specialist, Valeport. The new SWiFTplus uses Valeport’s world leading high accuracy sensor technology which incorporates turbidity observations with sound speed, temperature and pressure sensor technology to also provide computed conductivity, salinity and density. This is coupled with the convenience of Bluetooth connectivity and a rechargeable battery.
The handheld profiler, constructed from Titanium for unrivalled durability, has been designed from the outset with the intention of a seamless workflow and has an integral GPS to geo-locate every profile. SWiFTplus is intended for coastal, harbour and inland environmental and hydrographic survey use and offers high quality profiles in a compact, robust and portable package.
Valeport’s new turbidity sensor addition is effectively two sensors in one. The first is a “classic” turbidity sensor (nephelometry using a 90˚ beam angle) for low turbidity levels (0–2000 NTU) and the second uses an OBS optical backscatter arrangement (~120˚ beam angle for optical backscatter) at high turbidity levels (>20,000 NTU). Intelligent sampling eliminates the need to gain switch at higher turbidity levels.
Using a simple ‘twist and go’ switch on the unit, data can be easily and quickly downloaded, reviewed wirelessly via Bluetooth, using the new Valeport Connect app, allowing data to be instantly shared in industry standard formats through email and cloud services. Valeport’s new Connect software is also available on PC and can be used with a USB cable for instrument setup, data extraction, display and translation to common-format data strings and additional tools. Designed specifically for the operation of SWiFTplus and new to market Bluetooth enabled products, the new software simplifies and streamlines operation and data download tasks.
The SWiFTplus is now available to order. For more information contact: [email protected]
Fugro reports successful licensing of seep and geochemical data before Canada’s 2018 east coast bid round
Fugro and partner, Amplified Geochemical Imaging (AGI), have reported recent success selling licences for data from a frontier region offshore Canada. The data were acquired during a hydrocarbon seep survey, heat flow and geochemical coring campaign in the large Orphan Basin, situated on the continental margin of Newfoundland.
The comprehensive data package is being licensed from both Fugro and AGI and includes multibeam echo sounder data (bathymetry, backscatter intensity and water column), sub-bottom profiler data, heat flow measurements and shipboard geochemical screening analyses; shore-based screening and advanced geochemical analyses, including biomarkers on select samples, are also included.
Covering an area of 11,070 square kilometres, Fugro’s sea-based workscope in this frontier region included the acquisition of 99 cores for geochemical sampling and investigation, and shipboard analysis of approximately 550 samples for hydrocarbon geochemistry. Heat flow measurements were acquired at 11 distributed locations with two measurements taken per location; these data are a significant improvement on the three pre-existing heat flow measurements along the periphery of the Orphan Basin and will vastly improve the robustness of basin models. AGI performed the shore-based geochemical work using their patented ultrasensitive analytical method to determine difficult-to-measure hydrocarbon concentrations to test for thermogenic signatures. The different geochemical datasets (shipboard, conventional shore-based and AGI adsorbent-based analyses) all suggest the presence of thermogenic hydrocarbons.

In 2017, Atlantic Sapphire lost 250 tonnes of salmon in a mass die-off due to hydrogen sulphide poisoning from accumulated organic matter, an all-too-common problem in aquaculture with significant economic losses.
Growing salmon in land-based tanks in which water is continuously circulated (Recirculating Aquaculture Systems, RAS) means low waste discharge and high-levels of water re-use, but also sporadic toxic microorganism outbreaks that cause costly mass fish stock die-offs.
FluoRAS, Horizon 2020 COLUMBUS and EMFF ECO-AQUA are putting in place aquaculture trials of a fluorometer sensor system that can monitor organic matter online, and potentially reduce the risk of these die-offs. The FluoRAS system can potentially categorise and quantify different types of organic matter which accumulate in closed systems. The initial trials, using Chelsea Technologies Group BACTI-Wader Pro, will aim towards a real-time alert system, that gives enough warning time for operators to respond and avoid a potential toxic bacteria outbreak.
To learn more about the core technological solution see FluoRAS Sensor – Online organic matter for optimising recirculating aquaculture systems
The narrative is based on COLUMBUS Knowledge Transfer Case Study FluoRAS by Ivo Grigorov & Adam Hambly. For the full compilation of COLUMBUS Case Studies and their Impact, visit http://www.columbusproject.eu/project-results

PUPILS from Royal Grammar School in Newcastle have triumphed in the first ever national subsea STEM Challenge final, which saw 30 youngsters from across the UK compete in a dynamic competition to build a floating wind turbine.
The STEM Challenge, led and organised by Subsea UK and supported by The Smallpeice Trust, saw teams of second year students take part in regional heats across the country to earn their place in the final.
The finalists – Helston Community College (Cornwall), St. Andrew’s RC Secondary (Glasgow), The Portsmouth Grammar School, Royal Grammar School (Newcastle) and Sutton Grammar School, travelled to Aberdeen on Monday 14 May to go head-to-head in a bid to claim the top prize.
Prior to the final event, each team was given a Think Kit from The Smallpeice Trust, with all the tools needed to build a floating offshore wind turbine. The pupils installed their models in a test tank at Aberdeen Science Centre before presentations were delivered later at BP by students about their project plan, design and execution, to a judging panel of industry experts from Oceaneering, SMD and Saab.
The teams were then graded on the amount of electricity produced by their turbine, how well it kept afloat and their engineering knowledge of the subsea sector. They also got the opportunity to visit BP’s facility in Dyce where Paul Benstead, pipeline technical authority at BP provided a detailed insight into his role and what it’s like working at sea.
The new initiative, which launched earlier this year aims to encourage school pupils in STEM subjects to consider a career in the subsea sector.
EVENTS, TRAINING & DEMONSTRATIONS
Marine-i will be hosting a special free conference on Wednesday 23 May entitled: Technology in Surveying and Improving Marine Data.

The first international conference on Satellite-Derived Bathymetry (SDB Day 2018) is now open for registration to discuss key issues on capabilities, data integration and quality standards. The Satellite-Derived Bathymetry Technology and User Forum will be held on June 6 and 7, 2018 in the Bavarian Lake District near Munich, Germany.
According to the statistics maintained by the International Hydrographic Organization, over 50 percent of the world’s coastal waters have never been surveyed. However, there are many users who require current high-quality bathymetric information for this zone, highlighting the need to fill this data gap.
The Satellite-Derived Bathymetry (SDB) technology helps to address this challenge. Initially established as a reconnaissance tool for shallow water bathymetry only, cutting-edge SDB techniques are increasingly used as a cost-efficient and rapid survey method for acquiring high-resolution bathymetric data down to water depths of 30 meters.
The use of this technology in applications such as safety of navigation, reconnaissance surveys, coastal zone management and hydrodynamic modeling is increasing significantly, and there is therefore a compelling need to discuss current technological capabilities, application requirements and suitable quality standards of SDB data.
The conference will host international speakers, panelists and participants from North America, Europe, Middle East and Asia. Topics will include quality assurance and uncertainties, integration and use concepts, standards and capacity building.
EOMAP, one of the sponsors, is organizing the conference. Media partners are Hydro International and Eco Magazine.

M. Timo C. Gaida from Delft University of Technology recognised as winner of the Multispectral Challenge at GeoHab 2018
- Timo C. Gaida from Delft University of Technology was recognised as the winner of the Multispectral Challenge at GeoHab 2018 for its research paper “A multispectral Bayesian method for improved discrimination performance of seabed sediment classification using multi-frequency multibeam backscatter data”. The three judges Lloyd Huff, Jonathan Beaudoin and Chris Tiemann selected Timo C. Gaida’s research paper among six submissions from Institutions from around the world.
R2Sonic launched the Multispectral Challenge at GeoHab 2017, following the introduction of the Multispectral Mode available with R2Sonic Multibeam Echosounder Sonic 2026. This new feature enables the collection of multi-frequency backscatter data, spatially and temporally coincident, using one system only. Surveying the seafloor with this new feature will result in different measured acoustic responses which was suggested that it could help improve bottom characterisation.
The goal of Multispectral Challenge was to develop an algorithm that robustly and repeatedly determines bottom type based on multispectral data.
All research papers took different mathematical approaches to attempt to segment the seafloor based on multispectral backscatter data. Learn more about all six papers here.
All papers concluded that access to synchronised (in time and space) multi-frequency backscatter data is a cornerstone in the development of solutions for bottom characterisation.
If you’re interested in conducting research on multispectral seafloor characterisation and want access to the data set or would like to collect multispectral backscatter data in a specific area, please contact R2Sonic: [email protected]
