| Summary: | Progress Code: onGoing Purpose Macquarie Island’s king penguin (Aptenodytes patagonicus) population has seen dramatic change over the past two centuries. Following near decimation from commercial oil exploitation during the nineteenth and early twentieth centuries, annual chick numbers increased rapidly from 1930 to 1980. Since then, the population’s trajectory has remained unreported, and the environmental factors that might influence the population are not well understood. From 2007 to 2020, annual island-wide censuses of king penguin chicks were undertaken in the second week of August each year. This data was compared to environmental variables to understand what variables can be further explored to understand king penguin population changes. This data set contains chick count data, environmental parameters and R scripts used to investigate the current trajectory of the Macquarie Island king penguin population in relation to environmental variables. This data has been published in ICES Journal Of Marine Science (DOI to be provided).
