PalEON has a video

In keeping with the theme of coring pictures I wanted to share PalEON’s new video, produced by the Environmental Change Initiative at the University of Notre Dame.  It does a good job of explaining what PalEON does and what we’re all about.  There’s also a nice sequence, starting at about 2:40s in where you get to see a “frozen finger” corer in action.  We break up dry ice, create a slurry with alcohol and then drop it into the lake into the lake sediment.

Once the sediment has frozen to the sides of the corer (about 10 – 15 minutes) we bring the corer up and remove the slabs of ice from the sides, keeping track of position, dimensions and orientation so that we can piece it back together.  I’m on the platform with Jason McLachlan and Steve Jackson.

There’s a great section in there about the sociology of the PalEON project as well, although it’s brief.  So take a second and watch the video, it’s great!
