Scientists across Europe will revolutionise how we measure and monitor our changing oceans in a new 8.9 million research programme.
The TechOceanS project, coordinated by the National Oceanography Centre, will deliver a new generation of low-cost and easily deployable sensors capable of wide-scale monitoring of ocean bio-geochemistry.
The international programme will pioneer five new sensors, two imaging systems, a novel sampler and an Artificial Intelligence-driven image processing methodology, all capable of operating at depths beyond 2,000 metres.
Southampton experts in Electronics and Computer Science, including Professor Hywel Morgan and Dr Daniel Spencer, will use their skills in microfluidics and sensor design to develop miniature, autonomous biological analysers capable of continuous monitoring and characterisation of marine organisms (such as harmful alga) and micro-plastics in the oceans for many months at a time.
The interdisciplinary research will include Southampton's Dr Peter Glynne Jones and his expertise in the manipulation of microscopic particles using the forces generated by ultrasonic waves.
Professor Morgan, Head of the Biomedical Electronics Research Group, says: "The oceans are essential in regulating climate and produce most of the planets oxygen, yet are ruthlessly exploited. To better understand the health of the oceans we urgently require significantly improved ways of measuring key chemical, biological and ecosystem variables.
"This ambitious and exciting project led by the world-class National Oceanography Centre brings together internationally leading partners from all over Europe. It will revolutionise ocean measurements and will have long-term impact on our understanding of life in the oceans and the way we exploit these resources."
TechOceanS will actively engage with scientists, manufacturers, marine stakeholders and resource managers to target Essential Ocean Variables that currently can only be measured by observations from a ship.
Engineers at Southampton will develop automated methods to turn vast numbers of images taken in the ocean into numerical information about the distribution of species, habitats and plastic pollution, and transmit this in near real-time over the low communication bandwidths available in the open ocean.
This will allow researchers to be instantly aware of discoveries made by autonomous systems, regardless of where they are in the world, and allow people to adapt data acquisition strategies based on up-to-date information.
Professor Blair Thornton, Director of the Centre of Excellence for In Situ and Remote Intelligent Sensing (IRIS), says: "TechOceanS will be revolutionary for how imagery is used in ocean science. Most ocean sensors make continuous measurements of scalar values like temperature, salinity or pH, where the size of data is small enough to transmit over the acoustic or global satellite bandwidths available in the open ocean. Images on the other hand, are far too large to transmit directly, and the require non-trivial analysis to extract useful information from the scenes they capture.
"This means that people normally need to go out to sea and physically recover imaging systems to make the data accessible. For remote sites that are rarely visited, this can introduce delays of months or even years from when the original events took place.
"The edge computing methods we are developing in this project will make the cameras smart enough to reliably extract and summarise important information by themselves, and through intelligent interaction with remote hosts, transmit these finding efficiently and in near real-time. Researchers won't necessarily have to go out to sea in order to make discoveries."
TechOceanS - Technologies for Ocean Sensing - is funded by the European Union's Horizon 2020 programme.
University of Southampton student Richard Carter has drawn praise in a national electronics competition for a spinning on-bike light display.
Richard and his Persistence of Vision (PoV) display have been named the runner-up in the UK Electronic Skills Foundation (UKESF) Embedded Systems Competition sponsored by UltraSoC.
The achievement immediately follows the Universitys strong performance in the 2019 contest, where Southamptons Yanislav Donchev and Torran Green claimed the top two prizes.
A PoV display renders an image to the human eye by spinning and switching on and off a series of radial strips of LEDs fast enough that the brain considers the full circle to be a solid image.
Richard designed, created and trialled the light display as part of his MEng Electronic Engineering degree to exhibit a choice of images from the spokes of a bicycle wheel.
"My goal was to design a product that improves the safety of cyclists in the dark, providing a lightweight active light source that shines left and right relative to the cyclist," he explains. "In addition, the ability to display custom images uploaded from an app introduces some entertainment value to using the light.
"I thoroughly enjoyed designing and working on my project so the opportunity to be recognised for the success I achieved is especially rewarding. As with many embedded systems, there are many things from my project that I would like to improve on, and I have already started working on the next iteration of my PoV Bike Wheel Display. My thanks go to UltraSoC and UKESF for sponsoring, organising, and judging the competition."
Richard has boosted his career prospects as a UKESF Scholar. The scheme, which supported a record-breaking number of Southampton students in 2020, offers a £1,000 annual bursary and paid work placements with mentoring from a leading employer in the electronics sector.
Richard completed his sponsored internship as a System Validation Engineer with Qualcomm remotely over the summer.
A prominent member of the ECS Society (ECSS), he has shared his passion during his degree as one of the organisers of the Microhack hackathon, which gave students hands-on experience with microcontroller boards and sample hardware.
Professor Geoff Merrett, Director of Outreach and Recruitment at Electronics and Computer Science (ECS), says: "Many congratulations to Richard, it's great to see Southampton students being successful in the UKESF Competitions yet again. This is a testament to the excellent quality of our students, and particularly in the domain of embedded systems."
A protective respirator created by researchers at the University of Southampton is now being used by healthcare staff in over 20 NHS trusts around the country.
Over 10,000 respirators have been provided to trusts from the south of England to Scotland after it received approval from the Health and Safety Executive for use during the COVID-19 pandemic.
Experts in Electronics and Computer Science (ECS) worked with engineers, medical staff and industry partners to rapidly develop the Personal Respirator Southampton, known as PeRSo, which consists of a fabric hood for the wearer's head and a plastic visor to protect their face.
The small portable unit delivers clean air through a High Efficiency Particulate Air (HEPA) filter with belt-mounted fan pack and can be worn throughout a long shift and reused after appropriate cleaning.
The multidisciplinary team was co-led by ECSs Professor Hywel Morgan and respiratory medicine expert Professor Paul Elkington, who both were awarded MBEs for their work in the 2020 Queens Birthday Honours.
The respirator has also been honoured by the Royal Academy of Engineering with a Presidents Special Award for Pandemic Service.
Dr Ric Gillams, a Research Fellow in ECSs Biomedical Electronics Research Group, says: I felt very helpless in the early days of the pandemic and so I was delighted to be part of the PeRSo team. We had a lot of support from across the University, from Southampton General Hospital and from a large number of companies around the UK.
The pressure on healthcare workers is now even greater than it was in the first wave of the pandemic and the feedback from PeRSo users has been very positive. It is very rewarding to see the respirators in action and to have made a contribution to the safety of those working on the frontline treating patients with COVID-19.
As the country went into the first lockdown in March 2020, a collaboration of University engineers, clinicians at University Hospital Southampton and industry partners including McLaren, Kemp Sails and INDO Lighting came together to develop PeRSo. In just one week, this partnership turned an idea into a prototype which was then tested on wards and manufactured at scale by INDO Lighting in less than a month.
Dr Becky Eggleston, a doctor on the general intensive care unit at University Hospital Southampton, says: We are extremely grateful for all the work that the team has put into producing the PeRSo hoods. They are much more comfortable than alternative PPE, which makes a huge difference to us during our long shifts.
Being able to see each other's faces makes it easier for our team to communicate, and knowing that patients take comfort from being able to see the faces of the people looking after them is a boost to morale.
