  • No change in amount or sources of PAHs

    More than two years after Austin, TX, USA, banned refined tar sealants, there has been no discernable change in either the amount or sources of polycyclic aromatic hydrocarbons (PAHs) in sediment in Austin's waterways. Austin\'s ban went into effect on 1st January 2006. Results of a study of the ban's impact were just published in a paper titled Polycyclic Aromatic Hydrocarbons (PAHs) in ...

  • Oil spills raise ocean arsenic levels

    Oil spills can increase levels of toxic arsenic in the ocean, creating an additional long-term threat to the marine ecosystem. Research published in the journal Water Research describes how oil spills and leakages clog up seabed sediments, preventing them from bonding with arsenic and burying it safely underground. Arsenic is a poisonous chemical element found in minerals and is present ...

  • Discovery of an active methane gas system beneath Arctic seabed

    Researchers have discovered a methane gas system beneath the seabed off the west coast of Svalbard in the Arctic that has probably been active since the end of the last ice age, about 15,000 years ago. The methane, much of which is stored in the sediment beneath the seabed as methane hydrate, flows upwards to the seabed surface where it enters the water as plumes of bubbles. Led by Professor ...

  • Typhoons bury tons of carbon in the oceans

    A single typhoon in Taiwan buries as much carbon in the ocean - in the form of sediment - as all the other rains in that country all year long combined. That's the finding of an Ohio State University study published in a recent issue of the journal Geology. The study - the first ever to examine the chemistry of stream water and sediments that were being washed out to sea while a typhoon was ...
