In my previous post I presented a blink comparison of image R04C04 from the MODIS Arctic Mosaic, link. Hovering the mouse brings up the image ID, which is right of centre, and clicking on the image gives a larger image. Image R04C04 is in the region of low concentration shown in the US Navy's HYCOM model as a result of the recent May storm.
I've used the highest resolution, 250m per pixcel, and stacked a series of images in an image editor, then used crop to select a single region to show ice conditions since 2009 over the exact same region of the pack for the same day of the year (with dither to avoid cloud white-outs), and the 2013 state before the May Storm. I have then turned each image into a negative in order to bring out the water between ice floes, even under cloud. No other manipulation has been done, all images are in original resolution. The ice shows up dark, water between floes as white striations.
The animated gif is available in my Google Docs account, this link should bring up the viewer, which is excellent for large images. The image is too large to post on the blog itself. LINK.
