Fugro resumes acquisition of data for Norway’s MAREANO seabed mapping programme

Fugro has been awarded a hydrographic survey contract, valued at NOK 44.7 million (approximately €4.7 million), by the Norwegian Hydrographic Service. The survey is part of the MAREANO seabed mapping programme, which is financed by Norway’s Ministry of Trade, Industry and Fisheries, and the Ministry of Climate and Environment. Fugro has successfully completed numerous surveys for the programme since 2006, collecting more than 100,000 square kilometres of data.

In water depths that typically range from 80 metres to 1,700 metres, the survey area of approximately 14,500 square kilometres is located between the Norwegian Sea, the Barents Sea and the Arctic Ocean. Fugro’s equipment on the survey vessels, including MV Victor Hensen and MV Fugro Gauss, will collect high resolution, high density multibeam echo sounder data, together with sub-bottom and gravity meter data, to gather marine knowledge for the Norwegian mapping programme. The fieldwork is scheduled from June to November this year.

The main objective of the survey is to collect seamless, high quality datasets between bathymetry and acoustic backscatter. To achieve this, Fugro is deploying state-of-the-art-sensors and adopting advanced calibration techniques and oceanographic measurement workflows designed for this challenging environment. It is also utilising online monitoring QC and post-processing workflows.

With part of the survey area located above 80 degrees latitude, there is an opportunity for Fugro to test the “Ice Pad” solution from MARSAT, the consortium developing services for the maritime and coastal industry. Collecting the most recent information on ice coverage will assist the MARSAT project to support voyage planning and tactical navigation in limited bandwidth conditions, typically at higher latitudes.

This year Fugro is introducing another additional element which will bolster its ongoing contributions to crowdsourcing initiatives such as the Nippon Foundation – GEBCO Seabed 2030 project, the global initiative to produce a high-resolution map of the world’s ocean floor by the year 2030. To date Fugro has donated almost 100,000 square kilometres of bathymetric data, collected during transits to and from global survey areas, to Seabed 2030, and aims to boost this contribution with transit data from the MAREANO programme.

New Mediterranean observatory relies on Soundnine’s inductive telemetry and temperature/pressure recorders

The observatory is called THEMO (Texas A&M – University of Haifa Eastern Mediterranean Observatory) and comprises a shallow mooring (125 m) on the continental shelf near the edge of the Levant Basin, 25 km from Haifa, and a deep mooring (1500 m) located 50 km from Haifa.  Soundnine’s Enduro APT recorders (Acceleration, Pressure, Temperature) with built-in inductive telemetry are clamped to the jacketed wire rope mooring line at 11 depths between 5 and 85 meters.

They communicate through the wire rope with a Soundnine Ulti-modem connected to the buoy controller. The two moorings have real-time RF communication with a shore station linked to the University of Haifa where the data are displayed.

The EOStore Bathymetry expands the comfort zone of coastal engineers and surveyors

EOMAP has launched the world’s first commercial online store for global shallow-water bathymetry derived from satellite data. The EOStore Bathymetry provides rapid access to search for and request high quality data.

Satellite Derived Bathymetry (SDB) is now established as a valuable tool for the surveying, planning and management of coastal and offshore sites. Unlike other survey methods, SDB can provide shallow-water bathymetric data worldwide without the need for a physical presence in the area of interest. Thus, SDB offers a rapid and cost-attractive solution for the coastal, offshore and survey industries.

EOStore Bathymetry offers different horizontal spatial resolutions of the bathymetric grid of 2m to 15m. This makes it flexible and fit for purpose for surveying, as well as for but also for planning and modelling purposes.

Environmental consultants Plancton Andino (Chile) using CTG FastAct FRRf to monitor red tides as part of the Bivalve Molluscs Health Program

Chile is the fourth largest producer of mussels in the world and the health of the mussels is of paramount importance to the economy and human health. Environmental consultants Plancton Andino (Chile) are using a CTG FastAct Laboratory FRRf System to monitor red tides as part of the Bivalve Molluscs Health Program.

These “red tides” or Harmful Algal Blooms (HABs) are natural events occurring around the world. Since first being reported in Chile in 1972, in the Strait of Magellan these HAB have increased in both frequency and geographic coverage.

HABs are highly toxic and can create a serious problem for human health and the local economy. HABs are caused by the cell division of certain toxic microalgae, which are regular constituents of the planktonic microflora found in aquatic ecosystems. Their harmful effects can be caused by the presence of toxins, as occurs with the dinoflagellates responsible for Paralytic Shellfish Poison and lipophilic toxins and the diatoms responsible for Amnesic Shellfish Poison. Some of the marine organisms that filter microalgae, such as bivalve shellfish, concentrate these toxins. Consumption of these organisms may seriously harm human health and may even be lethal.

The CTG FastAct and the new Act2 FRRf systems consist of a multi-wavelength fluorometer that excites a sample with blue, green and orange light. This makes it well suited for the application of monitoring HABs, as many of these organisms will absorb light more strongly at green/orange wavelengths. This coupled with fluorometer’s broad detection range and the ability to monitor at high spatial and temporal resolutions, makes it the product of choice for tracking the onset-, peak- and post-bloom events of red algal tides.

CTG ALGAE-Wader Pro systems for Flanders

The Flanders Environment Agency (VMM) has taken delivery of a number of CTG ALGAE-Wader Pro systems to assist in their work in assessing Algae levels within the water environments within Belgium.  CTG’s representatives within the Benelux countries, Notra BV, assisted in arranging the demonstrations and the subsequent supply.

The CTG Algae-Wader Pro system was chosen after successful demonstrations within the swimming lake at Blaarmeersen Sports and Recreation Park. This is a typical example of the sites that will be monitored for algae concentrations.

The systems supplied to VMM are configured for measurements of Chl-a, Phycocyanin and Phycoerythrin and come with a handheld unit which provides both graphical and digital real-time data to the operator, with Red, Amber, Green thresholding, and logs the data for post mission extraction.  All data is both time and position stamped.  The three channels provided by the CTG TriLux fluorometer within the system will allow the VMM to not only measure concentrations of Chl-a but also help inform on the group type of the algae present.

Fugro’s new RAMMS technology advances bathymetric lidar mapping capabilities

Fugro is introducing a new bathymetric lidar system that delivers industry-leading depth penetration and point densities for nearshore and coastal mapping. Known as RAMMS (Rapid Airborne Multibeam Mapping System), the field-proven technology promises to deliver an efficient and cost-effective solution, dramatically improving upon other bathymetric lidar mapping capabilities.

Described as a first-of-its-kind multibeam lidar system, RAMMS was developed in partnership with Areté Associates. The system utilises push-broom laser technology and is based on 20 years of cutting-edge military technology for mine detection, developed via the U.S. Navy Small Business Innovated Research (SBIR) programme. It is also underpinned by over 25 years of bathymetric lidar experience for nautical charting.

The sensor’s compact design allows for rapid deployment on small aircraft of opportunity, including unmanned, fixed-wing aircraft. The resulting operational efficiencies are enhanced through rapid processing and data transfer capabilities.

Fugro is currently using RAMMS to complete several large-scale surveys in the Americas with projects in other regions expected to follow.

RAMMS is the second major technology innovation offered by Fugro in partnership with Areté Associates. In 2015 the companies launched the pioneering aerial survey platform known as ROCIS (Rapid Ocean Current Imaging System) to measure surface ocean currents. In high demand since then, Fugro has collected more than 168,000 nautical miles of ROCIS data in the US Gulf of Mexico to support offshore oil and gas operations.

Tcarta wins national science foundation grant to enhance satellite-derived bathymetry technology

TCarta Marine, a global provider of marine geospatial products, has been awarded a research and development grant by the National Science Foundation (NSF) to enhance and automate multiple techniques for deriving seafloor depth measurements from optical satellite imagery. The ‘Project Trident’ research seeks to transform existing satellite derived bathymetry (SDB) techniques by leveraging machine learning and computer vision technology to enable accurate depth retrieval in variable water conditions.

If successful, these enhanced bathymetric techniques will have positive impacts on operations related to oil & gas exploration and production, coastal infrastructure engineering, environmental monitoring, and geointelligence (GEOINT) activities.

In 2014, TCarta successfully commercialised a proprietary technique for digitally extracting water depth measurements down to 20 meters from high-resolution DigitalGlobe WorldView satellite imagery. The SDB products became popular with organisations operating in shallow coastal waters because the technology is more cost-effective and timely than traditional airborne and ship-borne bathymetric methods – with no adverse effects on the environment.

Project Trident aims to integrate wave kinematics, a technique patented by jOmegak to calculate water depths in shallow waters by analysing the patterns and speed of waves detected in satellite imagery. Wave kinematics has been applied successfully using Sentinel-2 and WorldView satellite imagery.

TCarta is soliciting beta testers for participation in Project Trident research. If you are interested,  contact Project Trident Principal Investigator, Kyle Goodrich, at [email protected] or please complete the online Project Trident survey (www.tcarta.com/blog/survey).

Thordon Bearings and heddle marine team up to convert ships to pollution free propeller shaft lines

Thordon Bearings Inc. and Heddle Marine Service Inc. have today signed a cooperative agreement under which the Canada-based ship repair company will work together with Thordon Bearings Inc. to promote the conversion of ships’ oil lubricated propeller shafts to Thordon’s COMPAC open seawater lubricated bearing system.

The agreement will create an action plan in which a specialist team, comprised of Heddle Marine and Thordon Bearings’ personnel, to offer support to ship managers and owners looking to ensure their vessels are fully compliant with environmental legislation prohibiting the discharge of oil from the oil-to-sea interface of ships’ propeller shafts. Shipowners could face substantial financial penalties if their vessels are found to be incompliant.

Leaking shaft seals are known to be a significant contributor to on-going pollution at sea. The use of biodegradable lubricants, which are an improvement over mineral oils, are still an extremely expensive option for shipowners and some are having seal compatibility issues. Even biodegradable lubricants still need to be reported to authorities when discharges occur.  Thordon provides a solution that uses seawater as the lubricant that meets all regulations, eliminating any risk of oil pollution.
