STRANGE BUBBLES IN A BEAUTIFUL AND PEACEFUL CANADIAN LAKE - They erupt in fire if lit with a match - They are methane gas formed when microbes consume organic matter at the bottom of the lake

  • A photographer has captured amazing images of methane bubbles in Banff National Park in Alberta, Canada
  • The pictures show a frozen lake with the icy 'circles' trapped underneath in fascinating formations
  • In the summer the bubbles simply rise to the surface and pop, but in the winter they are frozen within the ice
  • Methane is 25 times more potent as a heat-trapping gas than carbon dioxide, and ignites easily when lit

    • A photographer has captured amazing images of methane bubbles in Banff National Park in Alberta, Canada. Pictured are some methane gas bubbles underneath Vermillion Lake
    These lakes may look like they are full of bizarre floating sea creatures, but they are actually filled with thousands of frozen bubbles.
     
    Paul Zizka, 35, tracked down the natural phenomenon, which he photographed at Lake Minnewanka, the Vermillion Lake and Abraham Lake
    Snapped across Banff National Park in Alberta, Canada, the natural wonders are made of highly flammable gas methane.

    Abraham Lake is the most commonly-photographed spot for this occurrence. But adventure-loving Mr Zizka, who loves to explore, revealed Lake Minnewanka, pictured, offers rival views - yet is just a little trickier to get to
    The gas - emitted by bacteria after they consume dead organic matter - is fairly harmless, but these bubbles can cause an explosion if lit.
    The strange phenomena is caused when permafrost in the area begins to thaw out. Organic matter stored in the bottom of the lake begins to thaw out, and microbes decompose it, releasing methane
     The frozen bubbles form when microbes
    consume dead organic matter on the bottom of the lake
     
    The bubbles get trapped on their way to the surface and the ice thickens and freezes around them, which can create the ‘layered’ bubble effect seen in these images
     
    He said: 'All three lakes are ever-changing, cover wide areas and provide endless possibilities for the keen landscape photographer'
