Envenio’s Exn/Aero Set to ‘Turn The Tide’

Envenio’s CEO Ian McLeod will present to delegates at the Teledyne CARIS Conference 2017 in Ottowa, Canada, that takes place 17-22 June 2017. His paper, entitled 'High Resolution 3D Mapping For Current, Turbulence and Sediment Transport' highlights a notable, revolutionary ability to being able to study a subsurface environment at a high resolution, making use of computational fluid dynamics (CFD) techniques.  CFD solves the Navier Stokes equations in three dimensions and produces contiguous data fields that extend horizontally over large areas and vertically throughout the water column. Data fields include mean current and heading, hydrodynamic turbulence, and a variety of transported... (read more)

Were Tide Prediction Machines the First Analogue Computers?

In a research paper recently published in History of Geo- and Space Sciences, National Oceanography Centre (NOC) scientist Professor Philip Woodworth describes the history and basic principles of tidal prediction machines. Invented in around 1873, tidal prediction machines were analogue computers that provided an accurate and efficient means of predicting the ocean tide. Professor Woodworth: "Although only around 10% of the tidal prediction machines ever created were in operation at the Liverpool Tidal Institute, this paper demonstrates the central role of this institution, Arthur Doodson, and the UK more generally in this area of tidal science." Captain Scott's Discovery The present-day NOC... (read more)

Planet Ocean Distributes Radac Radar Wave & Tide Sensor

Planet Ocean (UK) has signed an exclusive representation agreement with Radac (The Netherlands). The agreement covers the UK and Republic of Ireland. Radac has been developing the WaveGuide system since 1996. This high-quality radar-based system monitors waves, tides and water levels. The WaveGuide is compact, reliable and robust. Where a fixed structure such as a platform, turbine or jetty already exists, it offers a simpler-to-install, largely maintenance-free alternative to buoy-based systems. The WaveGuide is a standalone system, which requires no calibration. It incorporates a web interface which allows direct access to the wave data. Unique to Radac is the WaveGuide... (read more)

Six Type-approved ADVETO ECDIS-4000 for Tide Sjø

Through its distributor Westronic in Bergen, Norway, Swedish ADVETO has secured an order for three newbuild High Speed Craft (HSC) passenger catamarans. Each newbuild HSC will be equipped with paperless Dual-ECDIS from ADVETO. The new order represents the ongoing upgrading programme to make all Tide Sjø´s HSCs compliant with the IMO resolution stating that "all HSCs should be fitted with an ECDIS".     Tide Admiral (image) is similar to the newbuilds and has already dual ADVETO ECDIS-4000 onboard.   "Westronic started to work with ADVETO´s ECDIS four years ago. I must conclude that according to my opinion ADVETO has... (read more)

Integrating Offshore Tide Model Output with Onshore Observations

Improving Correctors to Hydrographic Survey Soundings
The National Oceanic and Atmospheric Administration (NOAA) develops tide correctors for reducing hydrographic survey soundings to Chart Datum by using the Tidal Constituent and Residual Interpolation (TCARI) software to interpolate harmonic constituents (HCs), tidal datum elevation relationships and water level residuals from observations. Due to the complex tidal regime and limited coastal observations in the Bering Sea, the error associated with tide correctors generated from the TCARI interpolation exceed the 45cm National Ocean Service standard in some offshore areas. In an effort to develop a higher quality tide corrector, a method of blending offshore HCs from high-resolution tide models and... (read more)

Tide Gauge and Water Temperature Monitoring Network for the UAE

OceanWise is working with Seatronics to complete a three-year project to design, install and deliver a fully operational network of 34 water level and temperature monitoring stations for Bayanat LLC in the United Arab Emirates (UAE). The stations are positioned at strategic locations within UAE from the Western Region to the border with Oman, covering a distance of over 400km. Water level is being measured using Valeport VRS-20 Radars with water temperature being measured using PT100 sensors from General Acoustics. All equipment is solar powered and housed in Valeport's TideStation enclosures. Communication with the stations is being handled using the... (read more)

NOAA Tide Stations Upgraded to Better Detect Tsunamis

NOAA has upgraded 33 tide stations in an effort to detect tsunamis quicker as part of the National Water Level Observation Network. Network tide stations normally equipped to record tidal data once every hour can now collect tidal data every six minutes, and can transmit that date through NOAA's Geostationary Operational Environmental satellites (GOES). The upgraded tide gauges also collect one minute averaged tide data that are available to the Pacific Tsunami Warning Center and the West Coast/Alaska Tsunami Warning Center. This enhances the tsunami detection and confirmation capability of the centers, allowing forecasters to view real-time data of any... (read more)

Scotia Tide Deployment Barge Launched and Cable Installed

Cape Sharp Tidal, a joint venture between Emera and OpenHydro, has completed two significant milestone operations in preparation for the next phase of the tidal energy demonstration project: the installation of its subsea power cable and the launch of its deployment barge. The operation to lay the Cape Sharp Tidal interconnection cable is the first project component to be deployed and the only system of its kind in the world. The operation was completed during a single tidal cycle, while holding position over Cape Sharp Tidal’s berth site at the Fundy Ocean Research Centre for Energy (FORCE) near Parrsboro, Nova...

NLWKN Research Centre Tide and Wave Station Order

The research centre coast of the NLWKN–Norderney was delivered with 5 autonomous and maintenance-free working Wave and Tide stations LOG_aLevel from General Acoustics. The systems, all based on ultrasound technology, will be deployed around the Island of Norderney in the German North Sea and replace the existing pressure sensors. The pilot station, which was delivered in the previous year, delivered data even during strongest storm seasons. Due to the absolute accuracies of far below a centimetre, all wave troughs and crests, as well as all flanks were measured. LOG_aLevel contributes an important part to improve the level accuracy and the... (read more)

New Tide and Weather Systems for all ABP South Wales Ports

Associated British Ports (ABP) South Wales has chosen OceanWise to supply, install and maintain new tide and weather systems across its five South Wales ports: Cardiff, Port Talbot, Newport, Barry and Swansea.  ABP is a leading UK port operator that owns and operates a network of 21 ports across England, Scotland and Wales. As a leading operator, they are “backed by investment in modern facilities and equipment” that is “designed to respond to the needs of the customers whose businesses rely on our ports for access to international and, in some cases, domestic markets.” After conducting site surveys at each...
