PAMBuoy in St Andrews Bay

Novel Scottish technology for renewable energy sector launched in St Andrews

A NEW instrument to detect whales, dolphins and other marine mammals, and provide immediate alerts during the development of offshore wind, wave and tidal installations, will be showcased tomorrow Thursday to  an international audience at the University of St Andrews .

PAMBuoy™ was originally developed by SMRU Ltd, a marine mammal consultancy which is a commercial spin-out from the world-renowned Sea Mammal Research Unit at the university.

Begins a spokesperson: “PAMBuoy™ is a cutting-edge autonomous passive acoustic monitoring system for marine mammals. It operates 24/7 to automatically detect and classify vocalising marine mammals – whales, dolphins and porpoises, providing high-resolution data that can be used to identify species present and determine temporal patterns in use.

“The units are being manufactured by Marine Instrumentation Ltd, and the team has just made its first commercial sale to an engineering consultancy in Australia.

“This breakthrough in new technology is a major step forward in the race to construct offshore wind farms and wave and tidal turbines, an industry with great potential for the economic future of Scotland.

“A recent government report claims that Scotland could produce 40 per cent of the UK’s energy from offshore installations making electricity from our greatest natural resource – the sea.

“And that we have the potential to produce 25 per cent of Europe’s energy requirements from wind. Thus helping us achieve our emissions reductions targets through greener sources of energy.”

Says Dr Gordon Hastie, a marine mammal scientist who assisted the development team: “PAMBuoy™ is a revolution in marine mammal monitoring. It is a cutting-edge, autonomous, passive acoustic monitoring device, which should help mitigate potential impacts on marine mammals from offshore activities.

“PAMBuoy™ ‘listens’ for marine life, then delivers information about what’s swimming beneath, in real time back to a customer’s desk top, mobile phone or other hand held device, and if mounted in a buoy, derives its power from the sun via solar panels.

“Data is checked automatically for quality, and made available to clients immediately through secured parts of the PAMBuoy™ website,”

Jim McFarlane, managing director of operations at Scottish Enterprise, who have provided £100,000 in innovation grant funding to the project, said: “Building on the wealth of research and academic knowledge from the University of St Andrews, SMRU Limited has produced an exciting product which has significant global economic and environmental potential.

“We have worked closely with the company in recent years to support the commercialisation of this new technology and will continue to work with the organisation to help take PAMBuoy™ to a global market place that is hungry for innovative, environmental technologies that support growing industries like the offshore renewable energy sector.”

The spokesperson continued: “Passive Acoustic Monitoring (PAM) is the term used to describe the process of passively listening for sounds emitted by animals.

“Small cetaceans such as harbour porpoises, and other dolphin species can be extremely difficult to observe in the wild as they spend the majority of their time underwater, generally occur in small groups, and often present a low profile at the surface.

“These species are much easier to detect acoustically, as they regularly produce sounds for orientation, navigation, foraging and communication.

“The blue whale makes a low frequency moan, dolphins whistle and harbour porpoises emit high frequency echo-location clicks!

“PAM can be used to collect data continuously whatever the weather, day or night, and is a research tool which is increasingly considered for monitoring and mitigation purposes during industrial and high-risk activity in the marine environment as well as for behavioural and population research.”

Dr Hastie continues: “This technology grew out of a scientific interest in the behaviour of marine mammals and was partly inspired by seal tagging technology which transmits information by satellite to shore when the seals surface. Technology like PAMBuoy™ is gold dust to offshore wind farm developers, who seek to minimise impacts on marine life during their developments of greener energy production.”

The spokesperson went on: “The new system will not only support the offshore marine renewable energy industry, oil and gas companies, but also the regulators and academic researchers and help reduce the effects of potential operations on marine mammals.

“It can be placed in a buoy offshore, or placed onshore for example in a harbour application, and is clever enough to automatically recognise the species detected.

“The PAMBuoy™ will be invaluable for environmental impact assessments which look at the activities of marine mammals around proposed developments for wind and wave farms”

Professor Ian Boyd, chief scientific advisor at DEFRA, and founding director of SMRU Ltd and former director for the Sea Mammal Research Unit, said: “we are delighted to see fundamental research from the University of St Andrews, producing this very practical instrument.

“Cracking the problem of how to detect these animals reliably has taken many years. Efforts continue to develop the statistical methods that will result in estimates of marine mammal population size from the emerging data.”

SMRU Ltd was founded in 2006 and today employs 12 scientists who apply their knowledge of marine mammals to the challenges faced by industry of developing in the marine environment. The company has opened offices in Canada, USA, Uruguay, and Hong Kong to meet growing interest and demand for its products and services.

Douglas Mundie, group commercial director, said: “PAMBuoy™ is designed to help companies to meet their obligations in monitoring the impact of their activities on marine mammals. We quickly realised there was a lack of reliable instruments available to us which could detect marine mammal presence in real time.

“We have invested three years of research into creating the world’s first truly autonomous, real-time marine mammal detection and classifier. Using various power options including solar power and onboard computer, monitored remotely from our offices means that the unit can be deployed year round with little maintenance.

“Because the detections the unit makes are sent wirelessly to the user, PAMBuoy™ minimises the risk of valuable data being lost in poor weather. We see a global market for this device which can operate remotely for months on end. Tests in Scottish waters and in theUSAhave been highly successful.”

The spokesperson explained: “Initial prototyping trials with PAMBuoy™ began in St Andrews Bay in May 2011 and most nights the system detected the movement of dolphins in the Bay.

“Night detection would have been impossible with conventional survey techniques for marine mammals which use human observation to search for animals at the water’s surface, i.e. an individual with binoculars, hampered by bad weather and limited to daylight hours.

“A second Proof of Concept PAMBuoy™ unit was installed onshore, at the Lime Kiln Point State Park lighthouse on San Juan Island at Seattle in the USA. Its role was to listen for Southern Resident Killer Whales (Orcas) in the area during the late summer months.

“Both locations are now testing Mark II prototype PAMBuoy™. You can see their data in real time on the PAMBuoy™ website,

“The team of scientists which is developing this new Scottish product is led by Richard Baggaley, operations manager of Marine Instrumentation Ltd, together with by bio-acoustician, Dr Doug Gillespie, and senior software developer, Andy Maginnis. They are supported by marine mammal biologists Dr Gordon Hastie and Dr Cormac Booth.

“Also on display for the first time in the UK at the Showcase day, will be an application of PAMBuoy™ on Wave Glider.

“This is an unmanned autonomous maritime vehicle which can be programmed to travel from off the back of a simple fishing vessel, on its own, to monitor sea life in more remote locations using only the power of the waves for propulsion.

“A versatile platform, the Wave Glider is equipped with GPS and sophisticated computers for navigation and payload control, with satellite communication systems and state of the art ocean sensors to monitor and measure the environment around it.

“Its on-board instruments are powered by solar panels making it an extremely versatile platform.

“Working in partnership with American firm Liquid Robotics, who developed Wave Glider, SMRU Limited with Marine Instrumentation Ltd have created a more versatile application for this ocean research.

“SMRU Ltd returns all its profits back to the University via Gift Aid, to fund further research in the academic departments whose expertise is used during project work.

“The company uses the wealth of scientific expertise available in the University through the Scottish Oceans Institute making this easy to access by the industrial world.”
