Ground & Satellite Based Remote Sensing of the Sea Surface

Design of novel analysis techniques for the high resolution (10s – 100s of metres) mapping of waves, currents and bathymetry and other oceanographic effects using data from coastal X-Band Radar systems. Also the use of such data in long term monitoring of such sites.

Use of satellite data for intertidal mapping.

Application of low cost GNSS systems for remote sensing of the sea surface.

News:

• November 2024: New Paper Published in Geomorphology: "Seasonal mobility of transverse finger bars within a mixed sand-gravel bay measured using X-band Radar". This builds on some earlier work published as a EWTEC'15 conference paper teasing out subtle sea surface roughness signatures of subsurface features at the EMEC tidal energy site - but we have seen these at a number of sites now - expect to see more publications on this in the coming years as it is a brilliant way of observing how migrating sea bed features act as a sediment transport pathway. Dominique Townsend's new paper, resulting from her PhD, tracks some transverse bar features migrating at a site on the south coast of the UK

• May 2024: I contributed to a BBC World Service "Crowd Science" episode about measuring sea level - available on the BBC Sounds Portal: www.bbc.co.uk/sounds/play/w3ct5rh2 

• February 2024: The CoastSense (Marlan Maritime Ltd) mobile radar system, or 'Rapidar', (which has NOC knowhow at it's heart) gets a mention on the BBC website! https://www.bbc.com/news/articles/c72gr5qk64po

• January 2024: Short article on SWOT published in IMarEST’s Marine Professional Magazine in January edition: Article

• January 2024: We have won a UK Space Agency SBRI grant to work with Peel Ports and the Channel Coastal Observatory on applications of our Satellite Temporal Waterline Intertidal Mapping – and will also be using SWOT data to investigate the validity of tidal data in the case study estuaries. (PI: Christine Sams)

• December 2023: We have won one of the UKRI Digital Twin Grants: SPLASH, led by Dr Nieves Valiente at the University of Plymouth: https://www.plymouth.ac.uk/news/scientists-combine-ai-and-climate-data-to-create-a-warning-tool-for-coastal-flooding

• June 2023: We were delighted to host the 6th Sensing the Ocean with Marine Radar Workshop (SOMaR-6) here in Liverpool with approx 30 in-person participants!

• 2023: Check out our EO4SD web page at ESA – we have a super-cool animation of the evolving intertidal areas of Morecambe Bay using Sentinel 1 SAR imagery with a version of the Temporal Waterline Method modified for satellite data - https://eo4society.esa.int/projects/sar-twl/

• December 2022 The SWOT Satellite has been successfully launched! See : https://www.youtube.com/watch?v=1Rr2L2rVvdc

• February 2022: Presented some of the results from our HMS Magpie radar trials at the Hydrographic Society's Remote Hydrography Conference in Dublin. 

• February 2022: We have successfully completed a 2-week deployment of a low-cost, battery powered GNSS unit (a progression of the Loctips project) overlooking Crosby sea front during the sequence of three named storms during February 2022. A similar system was simultaneously deployed on the Seaforth Radar Tower overlooking the Queen's Channel. Many thanks to Peel Ports and the Maritime and Coastguard Agency for their support of this project! https://twitter.com/NOCmarinePhys/status/1500802515746664449

• November 2021: I have been awarded one of four 'Embedded Digital Researchers Applying Transformative Technologies' fellowships working with mmSensors (Marlan Maritime Ltd) to help transition our wave inversion algorithms to operational use on their radar network. This will allow bathymetry and current vector maps to be calculated at each radar site when and where there is sufficient sea clutter present on the raw radar data. This should keep me busy until May 2022 to say the least! NE/W007347/1 

• May 2021: Our work with the radar at Thorpeness has been published! Well done to all my co-authors for getting this out! "Nearshore Monitoring With X‐Band Radar: Maximizing Utility in Dynamic and Complex Environments" https://doi.org/10.1029/2020JC016841 https://twitter.com/NOCmarinePhys/status/1392052116068392962

• March 2021: We conducted a series of radar based mapping trials during February with the Royal Navy - we collected some fantastic data and are busy looking at the results now. See the RN's article on the trials: HMS Magpie tests groundbreaking software to rapidly map the seabed.
