    Animal manure has long been recognised as a valuable fertiliser and a source of renewable energy. It is also a major source of pollution, with emissions from stored manure accounting for approximately 15% of all agricultural greenhouse gas (GHG) emissions and more than 70% of all ammonia emissions in Europe.

    Ion Science - new protection against VOCs

    Offering a new level of enhanced, reliable protection against VOCs with the first 11.7 Cub personal solution from ION Science.

    In a 2018 report from the UN, it was revealed that a worker dies every 30 seconds due to exposure to toxic gases in the workplace. That such statistics still exist today is one of the reasons ION Science is working hard to create protective technologies for workers against VOC exposure. The new 11.7 eV Cub personal solution is the first of its kind and promises to be a game-changer for protection against exposure.

    ion science VOC sensorThe Cub 11.7 eV personal device is the latest addition to ION Science's world-leadingrange of gas and leak detection products. Using their 30 years of industry experienceand their extensive knowledge of both volatile organic compounds (VOCs) andphotoionisation detection (PID), ION Science continue to deliver excellence in protection for workers.

    The 11.7 eV sensor lamp is a notoriously difficult lamp to manufacture. Due to its highly sensitive nature, 11.7 eV devices in the past have been temperamental, require frequent lamp changes and ultimately end up with increased environmental exposure, affecting performance of the device.

    ION Science has tackled this issue and developed a refined manufacturing method that eliminates some of the sensitivities and issues previously associated with 11.7 eV detection.

    As the first 11.7 personal detection solution from ION Science, the Cub 11.7 offers all the features a customer would expect from the market leader.

    This includes resistance to humidity and moisture, operational in temperatures from 0-55 degrees, and intrinsically safe even in explosive environments. Its lightweight design at only 111g makes it comfortable for wearers and the small size doesn't impede movement or work.

Whales avoid wind farm's harmful foundation piling thanks to acoustic device

Research in Icelandic waters into protecting whales during the world-wide construction of offshore wind farms has discovered an acoustic device that keeps them out of harms way.

The Carbon Trust managed the new research to build confidence in the use of Acoustic Deterrent Devices Devices (ADDs) - a series of amplified electronic pulses projected into the water - to safeguard marine mammals during deep water offshore wind construction. It was as an Offshore Renewables Joint industry Programme (ORJIP), with funding from innogy, Ørsted, and Statoil.

Previous studies have demonstrated that ADDs effectively deter seals and harbour porpoise, however, until now there has been little research into the use of ADDs as a deterrent for minke whales. As minke whales are an important species in UK waters, the ORJIP study was set up to address this knowledge gap. The objective was to increase confidence in ADDs and specifically improve the techniques for safely deterring marine mammals during offshore wind construction. During the field research whales were observed to display a clear and sustained movement away from the ADD deployment site, adopting faster swim speeds with more directed movement.

During the construction of wind farms, where percussive pile driving is required for foundation installation, increased underwater noise levels are generated. The detection of marine mammals is currently carried out by marine mammal observers posted offshore, or passive acoustic monitoring (PAM). If a marine mammal is detected close to an offshore wind construction site, piling activity will not commence until it is deemed that there are no longer marine mammals within the predefined zone.

In particular, it increases confidence that marine mammals are adequately protected when operating in harsh conditions or poor visibility, and also avoids the need to unnecessarily delay construction operations.

Olivia Burke, manager of the ORJIP ADD project at the Carbon Trust said: "The findings will help increase industry and regulator confidence in the use of ADDs to actively manage the protection of marine mammals during the piling phase of construction."

Tracking results demonstrated that focal minke whales responded to ADDs at distances which could prevent injurious effects of subsea noise. The study revealed that the selection of appropriate ADDs for mammals with different hearing frequencies and appropriate deployment periods for the underwater environment were important considerations to ensure successful ADD deployment.

During the research a total of 246 minke whales were sighted, of which 46 focal whales were tracked. Focal follows including successful ADD deployment were carried out on 15 occasions. In all 15 deployments, the focal animal moved away from the ADD deployment site following activation of the unit.

The study site was located in Faxaflói Bay, southwest Iceland, selected as it is a summer feeding ground for minke whales therefore ensuring a high whale population density. Researchers worked from the specialist cetacean research vessel Song of the Whale and a secondary smaller vessel to ensure minimal disturbance. The Lofitech ADD device was chosen for the research as it had the greatest body of scientific evidence demonstrating efficacy at deterring other marine mammals. Video range tracking (VRT) was employed to measure minke whale response to ADDs during the Control Exposure Experiments.
