Machine Learning

Current measurements using HF radar systems are widely used. We have also demonstrated wave and wind direction measurements with good accuracy.

Methods to obtain wind speed have been suggested by a few authors but so far not been sufficiently accurate.

We have been working on a new approach using machine learning and a first paper on this has just been published in Remote Sensing

New Publication

Lucy and colleagues at the University of Sheffield have published a paper on the inversion of bistatic radar data

Remote Sens. 2020, 12, 313 doi

Seaview Sensing software was modified to carry out the inversions but the modification is not yet part of our operational software package. Until this has been implemented we can only process small amounts of bistatic data in house.

If you would like us to process your bistatic data do get in touch.

New Publications

Rachael Hardman recently completed a PhD at the University of Sheffield supervised by Lucy. A paper on this work has just been published.

Inversion of HF radar doppler spectra using a neural network. Hardman, R., & Wyatt, L. 2019. Journal of Marine Science and Engineering, 7(8). doi

The paper uses data from the University of Plymouth WERA HF radar. A validation of Seaview Sensing wave measurements from this system is published in the same issue.

Presentation

Lucy and Andrew recently attended the Radiowave Oceanography Workshop (ROW) 2019 in Victoria, Canada, where Lucy presented 'New Approaches to wave measurement' which included results from the InnovateUK dual frequency tests and new bistatic results linked to Rachael Hardman's PhD thesis.

Lucy also gave a lecture on 'Wave measurement using HF radar' at International Summer School On Radio Oceanography 2019 which preceded ROW.

Lucy presented a paper "Developments in metocean HF radar technology, application and accuracy" at the recent OMAE2019 conference in Glasgow.

This reported on the work we did with Neptune Radar and Swansea University partially funded by InnovateUK showing that simultaneous dual frequency operation has a positive impact on wave measurement accuracy.

Lucy presented ‘HF radars for offshore wind farm operations and maintenance support’ at Global Offshore Wind 2018, Manchester, UK.

We completed the installation of Seaview Realtime with Data Viewer for the HYD2M project at University of Caen, France. WERA radars have been located on the coast of Normandy to measure wave and current varaibility in the channel between Normandy and Aldernay.

Lucy presented ‘Developments in HF radar technology, applications and accuracy’ at the NPOP Ocean Prediction workshop in Liverpool, UK.

We completed the processing of 1 year of data from the Korean Advanced Institute of Science and Technology (KAIST) WERA radar on our server. Data delivered via our new Data Viewer and as ascii files via ftp.

Lucy presented ‘Measuring the ‘First Five’ with HF radar’ at the 1st International Workshop on Waves, Storm Surges and Coastal Hazards, Liverpool, UK and ‘Some reflections on HF radar wave measurement’ at ROW, Lüneburg, Germany.

Lucy presented ‘Wave power measurements in the Celtic Sea using HF radar’ at Oceans 2017, Aberdeen, UK

Lucy presented ‘Wave power measurements in the Celtic Sea using HF radar’ at Oceans 2017, Aberdeen, UK

InnovateUK have funded a one year project between Seaview and Neptune Radar Ltd. This project is part of our plan to develop the next generation of these radars that will be both cheaper and will provide more reliable wave measurements. This project focuses mainly on the reliability of the wave measurements with research on a new idea to exploit the fact that different radar operating frequencies have different responses to wave conditions.

Lucy presented ‘Using HF radar for storm surge monitoring’ at the Challenger Society Special Interest Group meeting on Ocean Wind Waves, HR Wallingford, UK.

Lucy presented ‘Wave and related measurements: Algorithms, QA/QC procedures, Limits and opportunities’ at the INCREASE HF Radar Experts Workshop, Lerici, Italy.

Lucy presented ‘Wave power measurements in the Celtic Sea using HF radar’ at the PRIMaRE conference, Bath, UK.

Lucy presented ‘HF radar wave measurement’ at the Advances in Ocean Wave Measurement Conference, The Royal Institution, London, UK and ‘Measuring waves with HF radar’ at the 3rd Norway-Scotland Waves Symposium, The Royal Society of Edinburgh, Edinburgh UK.

Lucy presented ‘Improving quality control and accuracy of HF radar currents’ at Oceans 2015, Genoa, Italy.

Lucy presented ‘Quality assurance and control issues for HF radar wave and current measurements’ at EGU, Vienna, Austria.

Lucy has returned to the UK.

Andrew has joined ACORN.

The new WERA-Wavebuoy product has been delivered to Helzel. This provides inversion data at one selected location in the field of view of the radar. It is available exclusively through Helzel GmbH.

A fourth ACORN WERA station with Seaview software is installed at Coffs Harbour in northern New South Wales, Australia.

Lucy has gone to Australia to take up a 3 year position of Director of ACORN at James Cook University, Townsville, Queensland. She will continue to work for Seaview during this period.

Seaview are working with the Australian Coastal Ocean Radar Network (ACORN) which forms part of the Integrated Marine Observing System (IMOS). The ACORN network currently consists of three WERA radar deployments in the Great Barrier Reef, Perth Canyon and South Australia Gulfs.

A further system is scheduled to be installed at Coffs Harbour in 2010.

Seaview Realtime software is being used to measure current, wind and wave parameters for each deployment and the data are processed at James Cook University in Townsville, Queensland.

The ACORN system provides a basis for applied research into wave modelling and offers test sites for hydrodynamic modelling. The radar data will be made freely available from IMOS via a national archive.

Seaview are to supply their metocean data software to the University of Plymouth and the Peninsula Research Institute for Marine Renewable Energy (PRIMaRE) for use in the new Wave Hub project in the South West of England. Data from a WERA radar system, processed using Seaview software, will be used to provide waves, in particular full directional spectra data and surface currents, across a field in real-time.

Wave Hub will create the world's largest test site for wave energy technology by building a grid-connected socket on the seabed, 10 miles off the coast, to which wave power devices can be connected and their performance evaluated. Wave Hub leases space to developers and exists to support the development of marine renewable energy around the world.

Seaview's Technical Director, Professor Lucy Wyatt, says "We are pleased to be providing our software to the Wave Hub project, it will provide everyone involved with valuable met-ocean data. We are seeing increasing interest in our data from the marine renewables sector. We expect that device developers will find the data particularly interesting and the potential to access the data online exists".

In response to client feedback the Seaview software now has the capability to provide met-ocean data in Grib format. Grib is a mathematically concise data format used in meteorology to store and manipulate weather data. This development will be particularly useful for Met Offices around the world and means that clients can integrate the data into their existing programs.

Technical Director and Company Founder, Professor Lucy Wyatt, says "We are continuing to work on new developments to improve our software and ensure it is of value to the end user. Being able to offer data in Grib format makes the data more practical for clients used to working with this format".

A survey conducted by Seaview Sensing in association with Wave Energy Today has revealed some interesting insights into the wave energy market. Insufficient knowledge, funding issues, political will and general uncertainty trouble the wave energy market.
