Probability of detection using Landsat-7 imagery.

<p>(A, B) The number of Adélie penguin colonies located (white) and missed (shaded) by the Landsat retrieval method for continental Antarctica (A) and the Antarctic Peninsula (B). The percent contribution of each bin to the total population is also illustrated. The horizontal axis is logarithmic, with boundaries equal to 10⁰, 10¹, 10^1.5, 10², 10^2.5, etc. (C, D) Probability of detection as a function of colony size (as reported by <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0113301#pone.0113301-Lynch1" target="_blank">[5]</a>) along the coast of continental Antarctica (C) and on the Antarctic Peninsula (D). Gray line represents best-fitting logistic model. Inset represents portion of the plot shaded in light gray.
