This is a 5 frames per second timelapse taken from the webcam at 30 second intervals of the Nenana Ice Classic on May 20th, 2013 from 4PM to 5PM PDT (15:00-16:00 AKDT). Breakup started about 15:43 AKDT (about 16 seconds in this video) in and went very quickly. Notice the ice stopped flowing in the river at the end, suggesting an ice jam formed downstream.
Watch the video:
Cool…
When it goes, it goes.
In the end, it did go quite quickly…
Just one thing – it went 16 seconds into the 23 seconds total.

——————–
Way too “cool”. Is this the “anthropogenic carbon dioxide to cause next ice age” tipping point ??
So this is a new record? The previous record was at 11:41 on May 20th…
Nice.
Cool video…
and how apt that the break up prize was won by Warren and Yvonne Snow.
The previous record was in a leap year, so this one shouldn’t count as a record.
Log jams?
Log jams could appear at various times and various places downstream, leading me to wonder how much the timing of the “melt” is a proxy for temperature, and how much the timing relates to chaotic ice/water flows downstream.
“ice jams”, not log jams.
Neither Strick nor remmer01 can read, nor comprehend.
This is a new record. Maybe things are different on their mother ship.
As Merrick points out in a related thread:
Ain’t modern tech wonderful?
I could almost feel the chill in the air !
Thanks for sharing effort Anthony

This is an example of why it pays us to keep our words sweet.
Your point about the distance of the break-up (“Proxy”) from the Vernal Equinox is interesting, substantive, and novel to me. But of course we are talking about May, not March.
Nice ! Very nice ! To the responders above, 1964 was a leap year (julian day 141) whereas this year is not (julian day 140) !

Need to factor in 0.25 from 1964 to 2013, then re-calculate, with adjusting for the lunar position and taking into account the solar cycle 10.2 cm and sun spot counts and then checking the jack-rabit population of Australia and the mass of elephants in South Africa … .
Ha ha.
Yes, indeed, it is a new record!! For all time! Unprecedented! A very ominous warning for global cooling. We must warn the world!!

(Apparently, our warmist visitors can’t seem to enjoy nature without ascribing some CAGW B.S. nonsense reason for it…sheesh!).
Anthony,
Thanks for capturing the frames and sewing them together for our amusement and education (on top of everything else you do).
I watched a few real time videos of previous breakups—I think 1973, 2009 & 2011—and I was quite curious how this one would go down.
It will be interesting to see if anyone present on the river bank will post a real time video of this one.
“leading me to wonder how much the timing of the “melt” is a proxy for temperature, and how much the timing relates to chaotic ice/water flows downstream”
So the real world is complicated and proxies are just that, proxies? Not gauges accurate to 1/100 of 1%? Next you’re going to try to tell me that tree ring widths might vary from a cause other than temperature. Noooooo….!!!
It was just slightly before that, I refreshed the image at 15:43:06 and the tripod was out of frame, I must have missed catching it in motion by just 30 seconds.
Hi-resolution video here:

The wooden tripod was sitting on an ice sheet at the edge of an open channel when the ice broke off and floated down the river, triggering a siren in town to notify residents the tripod was moving.
“A big (ice) jam broke loose upriver by the railroad bridge and started moving down,” Ice Classic manager Cherrie Forness said, referring to the Alaska Railroad bridge about one-half mile upstream of where the tripod sat on the ice. “It just kind of took the whole sheet of ice the tripod was on with it.”
The tripod was still upright as it floated down the river on the ice but it eventually tipped over and the ice jammed up, she said.
Bystanders on shore could be seen on a webcam taking pictures of the tripod as it floated down the river. A crowd of about 25 people were on hand to witness the historic event, Forness said.

Trolls are such funny creatures. If the iceout didn’t happen until next month they would blame anything instead of their stupid warmist religion.
Get over it trolls – it is a record
Please everyone, this is just an example of extreme weather which proves climate change. Just ask John Cook, he took a survey in which a consensus of 97% of those surveyed agreed.

I must disagree, kcom. You got your science all wrong.
The Nenana Ice Classic data is clearly more than just a proxy. According to Dr. R. Sagarin and Dr. F. Micheli it is a “remarkably accurate record of global climate change”. I know it because they wrote a paper about Nenana in 2001 and got it published in the Science magazine. They used math in their paper.

A true hockey stick, it is.
How appropriate that the winners in guessing the time of the ice breakup are named Snow.
Beautiful vid; thanks.
