Random Walk of the Penguins

Competitors built hundreds of algorithms to predict changes in Antarctic penguin populations from the most comprehensive counts available. These algorithms give researchers a greater understanding of penguin population dynamics, a leading indicator of climate change. #climate

About the data


The data for this competition comes from the MAPPPD project and from dedicated penguin counters in the Antarctic. This includes data from peer-reviewed publications, reports, or projects like the Antarctic Site Inventory.

Penguins are counted like this (360 video!):

The counts are made up of raw chick and/or nest counts for sites all around the Antarctic continent for three species: Gentoo, Chinstrap and Adélie penguins. All three species nest on the Western Antarctic Peninsula (south of South America), and in some cases will nest in the same colony. On the Peninsula, Chinstrap and Gentoo penguins are restricted to the more northerly regions, while the Adélie penguin is the only species of the three that nests around the entire continent.

Different penguin species have different ecologies...That is to say, how and when they breed differ between species, as well as where and when they eat. They also have slightly different diets, with each species eating various amounts of krill or fish species depending on their location (see Background Materials). The three different species also rely on sea ice in different ways. Finally, the timing of breeding can change from year to year (which would affect the total counts), and is different between the three species.

This competition is a first (of which we are aware) for ecological time series. Due to the nature of the data, we expect this to be challenging, and metrics of success for these exercises in academia are often quite low. If you examine the background material, you will gain some understanding to the nature of the models that currently exist for penguin population dynamics in Antarctica.
