Lake Superior Ice Cover

The Lake Superior Ice Cover is nearing 100% - perhaps by the end of the week we will see it completely covered. Very "Cool" to say the least.

  2. Yup, deceiving.
    Once the winds shift from the Northwest, it will close up quick.

  3. Dennis, can you explain why the wind direction affects the ice on the lake visible in these cameras? I'm always surprised when the channel under the bridge is free of ice. I would have guessed that this would be the first to freeze.

  4. Hi,
    With the strong winds out of the Northwest, the ice get blown to the South and leaves the open water along the North Shore.
    The water current in the the canal is fairly strong, much like a small river, thus keeping the water open. It will freeze up, or get plugged up with ice, but usually doesn't last long.
    In the Springtime, you will be able to see chunks of ice drifting back and forth through the canal as the current reverse several times a day due to a phenomenon called a "seiche" (SAYSH, a French word that means "to sway back and forth"). This happens when water piles up on one side of the lake because of wind or high barometric pressure and then shifts back to the other side. Small seiches occur all the time.

  6. Can anyone enlighten a dumb Iowan as to what kind of bird/duck those very hardy little critters are that still swim in the ice cold water of the canal?? We don't have any water birds around here that I know of that would stay so late into the winter.They are smart and head south like I wish I could! :)

  7. The ducks are Buffalo Heads, Golden-eyes and Mallards. Tough little critters.

  13. It is very interesting to see the various ships that come and go. Together with maritme maps which show position , name and size as well as flag, I often tune into the cam here in Duluth. I live in Israel but lived in MN for 10 years.

  14. I tune in to the cams here every day. But for the past two weeks or so I have been getting a message " a long running script is preventing the page from loading" Clicking the 'stop script' button does not work to fully get onto your site. I suggest you remove whatever "script" this is or you will lose your users. Obviously it doesn't improve your site. I love tuning in frequently. Please correct this problem. If I have it, others might, too. Thanks and hope to "see" you soon.

  16. I have the same issue on two different computers both using Internet Explorer. I have to view the cameras using Google Chrome now. Chrome is not my browser of choice. This just started a few weeks back. Love the cameras though.

  17. March 30th 2015 : Why are so many of the cameras not loading right now? I really miss checking out the many views.
