GISP2 ice core with annual layers[edit]

This photograph shows a 1 meter section of the GISP2 ice core taken from a depth of 1837 meters in the Greenland Ice Sheet. Annual layers are clearly visible.
{{sofixit}}: Here's the crop we all wanted. It also reduces the file size somewhat.--HereToHelp 15:39, 6 April 2007 (UTC)[reply]
Reason
Ice cores are difficult things to photograph well and few people have access to them, which I think makes this photograph quite remarkable, even if it isn't going to win any awards for artistic quality. I acquired a copy of this image from NICL staff while recently doing work there. I can't imagine a more informative image for illustrating the concept of an ice core with annual layers, and have never seen an ice core image with anywhere near this resolution. For the record, the grainy texture in close up is a property of the ice, and not the image.

  • Support: Very nice picture.  ~Steptrip 02:12, 6 April 2007 (UTC)[reply]
  • Support if black border is cropped out. A down-sampling might also be helpful. Also, there is no sense of scale (a problem with our last ice nom, if I remember correctly)--HereToHelp 02:18, 6 April 2007 (UTC)[reply]
    I don't follow FPC. Out of curiousity, could you point me to the previous ice nom? Dragons flight 02:21, 6 April 2007 (UTC)[reply]
    Wikipedia:Featured picture candidates/Ice Block. It could be an ice cube or a small glacier.--HereToHelp 02:27, 6 April 2007 (UTC)[reply]
  • Supportifcropped per HTH, except of course it's a meter long, so we don't need a "sense of scale" here. It's a scientific specimen. And the caption rocks too. ~ trialsanderrors 03:12, 6 April 2007 (UTC)[reply]
    • That was a minor quibble that I'll overlook if cropped. One other thing, though: which side is older?--HereToHelp 13:57, 6 April 2007 (UTC)[reply]
      • I think you can just upload the cropped version over the original. There's no artistic content that got lost because of it. ~ trialsanderrors 18:39, 6 April 2007 (UTC)[reply]
      • Not that anyone could tell the difference from the photograph, but I believe the left is older/deeper. Dragons flight 22:19, 6 April 2007 (UTC)[reply]
    • I was going to, but I wanted to preserve the old version so the archives would make sense. Also, the new version allows it to be posted to the Commons.--HereToHelp 19:43, 6 April 2007 (UTC)[reply]
  • Support iff cropped, the black border adds nothing but a buffer. Agreed on sense of scale, we know exactly how long it is. --Golbez 06:37, 6 April 2007 (UTC)[reply]
  • Support the cropped version. Beautiful, encyclopedic, and the crop makes the slight background noise around the ice core almost impossible to see. Enuja 20:07, 6 April 2007 (UTC)[reply]
  • Comment. I sort of like the black framing myself, but I'd support either version. Dragons flight 21:47, 6 April 2007 (UTC)[reply]
  • Support (either version) but it could be made more obvious that it's 1 meter long and which side is "up" (in the description). —Pengo 23:18, 6 April 2007 (UTC)[reply]
  • Question - Can we be sure that there's no copyright issues? Mrug2 00:00, 7 April 2007 (UTC)[reply]
    • NICL staff are USGS employees and so their work is public domain by virtue of being part of the US government. Not to mention that they are happy to have it appear in Wikipedia. Dragons flight 00:50, 7 April 2007 (UTC)[reply]
  • Support cropped Very nice image. I love the detail, expecially how you can see the little specks of dirt scattered around the ice core. --BeefRendang
  • Support cropped Very nice detail, definitely makes one interested in reading the article. Does anybody know why the layers are tilted somewhat? Was the core drilled at an angle? Or can snow/ice be sloped and maintain its shape over 38 years? --Interiot 00:22, 8 April 2007 (UTC)[reply]
    • The core is vertical; it is the ice sheet that slopes and flows. Dragons flight 20:51, 8 April 2007 (UTC)[reply]
