Emperor Penguins Counted From Space

HairyNevus writes "An international team of scientists used satellite technology to conduct a census of emperor penguin populations from outer space. Honing in on their colonies by looking for the brown patches of penguin guano that stand out in the snowy antarctic, high resolution images were taken and used to count the total number of emperor penguin species on the continent. The result was a census of 595,000 penguins, almost double the previous estimates of 270,000-350,000 emperors. This includes seven new colonies which had not been previously identified. Although this is uplifting data, computer modeling still shows that loss of ice flows in the northern reaches could result in problems for the penguins."

      Now you've got me wondering what the maximum resolution of a shoggoth's eye complex is, if it puts every bit of pseudo-protoplasm it can into forming eyes. What's the maximum light gathering area for a 40 cubic meter volume typical shoggoth, and does it compare favorably with the Hubble, the Keck telescopes or the very long baseline array? Can a shoggoth count the satellites in orbit? And does it want to eat them? Can a satellite fail a 1D20 sanity roll? And how could we tell?

  4. Counting seems like an "easy" problem by ninjackn · · Score: 2

    The video in the article mentions that the computer does most of the counting and I get the feeling that surveying animal count from aerial photographs might only work with penguins in Antarctica. It's relatively easy to distinguish between snow, poop and penguin from a computer vision algorithm stand point seeing how it boils down to distinguishing between black or brownish spots with little noise from other unwanted objects. Not that I'm trying to say it's trivial to program it but it it's a lot simpler problem than say counting people in a city from space or cars.

      From the paper:

      Emperor penguins show
      as single or multiple pixels in the panchromatic band. Where
      penguins are dispersed, individuals can be identified and counted.
      However, in the majority of cases penguins group into close
      clusters and their shadows overlap, meaning that individuals
      cannot be differentiated and a different approach is needed.

      So it's not really as easy as it may first appear.

    Guano is generally construed as being the excrement of seabirds (under which penguins are classified), bats, and seals. So, no, "penguin guano" is not redundant, as it distinguishes it from the guano of non-penguin seabirds, bats or seals.

  12. Obligatory Grammar Nazi by Cimexus · · Score: 4, Informative

    There's no such phrase as "honing in" on something.

    That phrase is similar to "intensive purposes", in that it results from a perpetuated mishearing of another phrase. You can "home in" on something - the phrase is "homing in". But to 'hone' means to sharpen (one's blade, one's skills, one's wit etc.)

    I am sure some will find some links that suggest that it's such a common mishearing that it has now become acceptable, but I don't agree. Both the Merriam-Webster (for US English) and the OED (for UK/Commonwealth English) state that "hone in" is an error.

  13. I'll go into bat for this one by dbIII · · Score: 4, Informative

    Bats, equitorial seabirds, arctic seabirds and many things that crap in one place in large volumes produce guano. It is a word cool and exotic enough to be in a list of ingredients for an energy drink, but it really does just mean deposits of crap that have built up over a long time. In some places it's a valuble resource due to it being a easily obtained source of nitrogen for fertilizer and explosives. In the days of gunpowder it was paticularly valuble and was apparently a major source of income for countries like Chile.

    It isn't mentioned in the article but the technology isn't yet advanced enough to count the penguins while they are moving, so the satellite had to kill them all using a death ray. They hope to have this problem resolved for next years census, which is predicted to be much quicker.

  16. Reason: Whales by ShanghaiBill · · Score: 4, Interesting

    One reason the population of penguins is increasing, is because of the huge reduction in the baleen whale population in the Southern Ocean. Baleen whales and penguins compete for the same krill, so fewer whales means a lot more food for the penguins. When the whale populations rebound, the penguins population will return to normal.
