  • Plastics in the Marine Environment

    An ongoing study of biodegradation rates of polymers has led to the development of a new ASTM International standard, D7473, Test Method for Weight Attrition of Plastic Materials in the Marine Environment by Open System Aquarium Incubations. The new standard is under the jurisdiction of Subcommittee D20.96 on Environmentally Degradable ...

  • Assessing the effectiveness of marine reserves

    Marine Protected Areas (MPAs) are intended to conserve marine habitats and fish populations and many prohibit fishing inside their borders. However, according to a recent study, local fishing activity can become concentrated around the edges of MPAs, which can have a significant impact on their effectiveness as fishery management tools. MPAs are designed to protect population and breeding centres ...

  • Panama Canal Marine Resistivity Survey with SuperStingR8

    The AGI SuperStingR8 with marine streamer and graphite electrodes(US Patent 6,674,286) were deployed along the entire 77-km long Panama Canal at 25m transect spacing to total 773 line-km of data.  This is the largest towed marine resistivity survey of this type to date.  AGI SuperStingR8 Marine resistivity data were successfully used to estimate geotechnical properties of the canal ...

  • 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 ...

  • 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. ...

  • Marine litter in deep sea ecosystems of the Mediterranean

    Marine litter is a major issue in deep sea ecosystems in the Mediterranean Sea, new research confirms. A recent study shows that the total weight of litter found in these sensitive areas often equals, and even exceeds, that of the animals that live there. This work can provide a baseline for assessments of the impact of deep sea marine litter and to inform future policy reforms, the researchers ...

  • Strong connections found between marine protected areas

    Marine Protected Areas should be managed as integrated networks rather than isolated units because of the high degree of exchange between them, a new study suggests. The researchers found that the large majority of sea bream (Sparidae) and wrasse (Labridae) fish spawned in MPA study sites in the Mediterranean Sea were transported via currents to other MPAs and unprotected areas, highlighting ...

  • 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 ...

  • Dangerously high levels of endocrine disrupting chemicals found in marine sediments

    Endocrine disrupting chemicals (EDCs) can interfere with the hormonal systems of both humans and wildlife. New research quantifying EDCs in marine environments in Greece found concentrations which present significant risks to sediment-dwelling organisms. Reduction and prevention of chemical pollution and subsequent harm to marine ecosystems is a key aim of the EU Marine Strategy Framework ...

  • Sewage Contamination Causes Concerns for the Oakland Athletics and Seattle Mariners

    Last month, it was reported that the Oakland Athletics and Seattle Mariners were forced to use the same locker room at the Coliseum. This resulted after a sewage backup flooded both team’s locker rooms, forcing them to share the Oakland Raiders’ facilities.  This is not the first time that backed up plumbing has caused issues at the 47 year old stadium. Although ...

  • Link discovered between extreme weather event and marine ecological change

    Plymouth scientists have discovered evidence of a direct link between extreme weather events associated with climate change and episodic changes to the ecological conditions and processes of the marine environment of the Western English Channel. These modifications could have significant implications on how our coastal seas function in the future and ultimately, on the goods and services provided ...

  • Plastics can concentrate toxic pollutants, endangering marine ecosystems

    Plastic debris is a serious environmental concern, as a physical pollutant as well as a chemical pollutant when it breaks down in the marine environment. A new study has now shown that plastics can also concentrate other pollutants, with significantly higher concentrations of toxic pollutants adhering to soft, rubbery plastics, rather than hard, glassy plastics. Marine species, including fish ...

  • Plastic litter can pass on pollutants and chemical additives to marine wildlife

    New research has provided the first conclusive evidence that microplastics ingested by marine wildlife can transfer toxic pollutants to their tissues. The researchers studied lugworms fed on PVC particles contaminated with either widespread marine pollutants or plastic additives and found that these ‘earthworms of the sea’ absorbed the chemicals into their gut tissue, which reduced ...

  • SMHI and SYKE in Finland enter a unique collaboration on marine environmental monitoring

    SMHI and SYKE, the Finnish Environment Institute, have begun a close collaboration to monitor the marine environment of the Baltic and the North Sea. “It is unique for two countries to sign an agreement in this way, but we are leading a trend that the EU and the global organization ICES would like to see going forward. As a combined force we can improve the monitoring of the acute problems ...
