Hear the Otherworldly Sounds of Skating on Thin Ice | National Geographic

  • Published on Feb 9, 2018
  • This small lake outside Stockholm, Sweden, emits otherworldly sounds as Mårten Ajne skates over its precariously thin, black ice. “Wild ice skating,” or “Nordic skating,” is both an art and a science. A skater seeks out the thinnest, most pristine black ice possible-both for its smoothness, and for its high-pitched, laser-like sounds.

    Black ice is recently frozen, and can be as thin as 2 inches and still support the weight of a skater. Like a dome or arch, the support comes from the sides rather than the top, and the water underneath prevents the ice from breaking. But, experience and careful advance planning are key. Factors including temperature, atmospheric conditions, and even satellite images of the Earth’s surface are considered. It’s complicated, but appealing to mathematicians like Ajne. Even with preparation, there’s a risk of falling in… So it’s best done in groups, for safety.

      Puhleez, I hear this very sound (sonar beep) any time I toss a rock straight up into the air and have it land on ice that's more than 6 inches thick when ice forms on waterways here in NJ.
      I once hit a golf ball with a baseball bat across a frozen lake down beyond Chatsworth NJ and kept hearing the "sonar beep" even when the golf ball was more than 300 yards away.
      This is nothing.

    If you should go skating
    On the thin ice of modern life
    Dragging behind you the silent reproach
    Of a million tear-stained eyes
    Don't be surprised when a crack in the ice
    Appears under your feet
    You slip out of your depth and out of your mind
    With your fear flowing out behind you
    As you claw the thin ice

    Very familiar sound to any Nordic person who likes to spend time outdoors. This is just small compared to the almost explosive fracture sounds during springtime when the ice is super thick but the sun is starting to warm it up. I've actually felt the ice tremble due to those while ice fishing.
