Updated ICESCAPE routines are submitted and a short review of the software is presented. Several recent studies indicate the usefulness of ICESCAPE for standardising Adélie penguin population counts taken at potentially different points in a breeding season. Such standardisation admits the possibility of, for the first time, comparing Adélie penguin population counts across space and time for all historically published population estimates. Recently added functionality is described, along with several suggestions for further work.
