  • The Chelsea Mariner Shuttle for Large Marine Ecosystem Monitoring

    The new Chelsea Mariner Nu-Shuttle is based on the successful Nu-Shuttle towed oceanographic vehicle. It is a generic, robust monitoring system designed for regular monitoring of large marine ecosystems. Undulating behind a research vessel or ship of opportunity it enables a wide range of oceanographic measurements to be made underway from the surface to depths in excess of 150 metres. ...

  • Finding the ASX200 for marine ecosystems

    The state of an ecosystem can be understood by measuring the right ecological characteristics, just as the ASX200 index shows the state of the Australian stock market by following 200 selected stocks. CSIRO Wealth from Oceans Flagship scientist Dr Keith Hayes, one of the leaders of the project, says the difficult part is selecting which characteristics to track. “Ecosystems respond to multiple ...

  • Coastal structures change marine ecosystems

    The urbanisation of coastal areas and introduction of man-made structures, such as jetties and seawalls, are changing marine environments. A new analysis highlights the impacts of these changes on marine plants and animals and suggests options to manage the detrimental effects. Many of the world's largest cities are in coastal zones and more than 75 per cent of people are expected to live within ...

  • Lugworms harmed by marine microplastic pollution

    Microplastic pollution impairs the heath of the marine worms that help maintain sediments for other creatures, new research suggests. This study shows that the energy reserves of lugworms living in sediment contaminated with microplastic particles were reduced by up to 50%. Microplastic pollution, fragments of less than 5 mm, is of increasing concern. Although the pieces are typically formed as ...

  • The environmentally effective remediation of marine sediment

    31st July 2006: Following a series of successful trials around the world, Virotec’s patented technologies are set to penetrate the UK market to great environmental effect. Their innovative ViroSoil™ Technology has been shown to offer a viable and economic total treatment solution for contaminated marine sediment through the neutralisation of the acid generating capacity of the dredged ...

  • Impact of climate change on marine algae

    With climate change looming large, countries around the world are mobilising their top scientists in an effort to measure its impact on the environment and society. One such scientist is the young Dr Björn Rost, who was recently awarded a EUR 1.4 million Independent Researcher Grant by the European Research Council (ERC). His research will focus on the impact of climate change on micro algae in ...

  • Pollutants released by seafloor trawling affect marine life

    Commercial bottom trawling, the technique of pulling fishing gear across the seabed to catch fish and other seafood, releases pollutants trapped in the seabed, which can negatively affect local marine life and ecosystems. Recent findings from a Norwegian fjord show how mussels can take up high levels of contaminants released by trawling, with important health implications for consumers. ...

  • Mussels: Biomonitoring tools for pharmaceutical pollution in the marine environment?

    Pharmaceutical pollution of marine environments has important biological consequences for aquatic organisms. This study investigated the effects on mussels of treatment with environmentally relevant levels of an antidepressant, fluoxetine, and a beta-blocker, propranolol, using biomarkers including DNA damage. The results showed that mussels are most vulnerable to these drugs in combination. Many ...

  • Marine life in reefs and coastal waters critically endangered

    Many marine ecosystems are facing mass extinction as a result of human activity, such as habitat destruction, acidification of sea-water and overfishing. New research into the regions and species most at risk suggests that up to 90 per cent of large predatory fish stocks have disappeared, transforming complex food webs into simplified ecosystems dominated by microbes and algae. The research ...

  • ET MARINE’S SEANOX ANALYSER GETS DNV ENDORSEMENT

  • Hazardous substances in Europe’s fresh and marine waters – an overview

    Hazardous substances in fresh and marine water can harm aquatic life and pose a risk to human health, according to a new report published today by the European Environment Agency (EEA). The report notes that while European legislation to address the issue is relatively strong, new challenges exist including ‘emerging pollutants’ where potential effects are not yet fully understood. ...

  • No plain sailing for marine life as climate warms

    Direct effects of climate warming on biodiversity pose a serious conservation challenge for marine life, according to new research published today in Science. Marine life may need to relocate faster than land species as well as speed up alterations in the timing of major life cycle events. This challenges previous thinking that marine life in the ocean would respond more gradually than ...

  • Better protected seas promised in UK Marine Bill

    New marine nature reserves around Britain’s coast are among radical plans published by Environment Secretary Hilary Benn. A new network of marine conservation zones, for species and habitats of national importance, will be put in place by 2012 under new powers contained in the government’s draft Marine Bill.  The new marine conservation zones will have clear conservation objectives, to ...

  • Barr builds largest marine tank in 15 years

    The custom fabrication department at BARR Plastics Inc. has completed a notable project to manufacture the largest plastic marine wastewater holding tank in the company’s manufacturing history. Measuring 20 feet long, six feet wide and four feet deep with a capacity of 3,500 gallons, the tank was built to be installed into a barge for the marine construction and repair company, Latitude ...

  • Mariners should use caution near buoy site

    The U.S. Army Corps of Engineers and other agencies deployed a data buoy off the coast of Block Island, Rhode Island, three years ago to gather information on wave action for a Corps study and the scientific instrument has been providing useful information to scientists, mariners and the general public since that time. One of the main purposes of deploying the data buoy was to acquire wave ...

  • Canada gets failing grade on marine protected areas

    Canada hasn’t made a lot progress on its commitment to establish a system of marine protected areas in our oceans concludes a new report by the David Suzuki Foundation, the Living Oceans Society, and the Sierra Club of B.C. The report card compares the performance of Canada, the United States, and Australia in designating marine protected areas. Canada gets a failing grade despite the fact ...

  • Water at Marine base linked to birth defects

    A long-awaited study by the U.S. Centers for Disease Control and Prevention shows a link between tainted tap water at a U.S. Marine Corps base in North Carolina and increased risk of serious birth defects and childhood cancers. The authors of the study on Camp Lejeune released late Thursday by the CDC's Agency for Toxic Substances ...

  • Plastic pollution measured in Mediterranean seabirds

    Endangered Mediterranean seabirds are suffering from ingestion of plastic litter, a recent study has shown. Overall, 66% of 171 seabirds studied were found to have plastic fragments in their stomachs and the critically endangered Balearic shearwater was among the worst affected. Plastic pollution in marine ecosystems is recognised as a key problem in the Marine Strategy Framework Directive1 and ...
