THANK YOU Dr. Gorman, Palmer Station LTER and the LTER Network!!! See complete data information & citations below.

Data for 3 penguin species (Chinstrap, Adélie, & Gentoo) have been combined into a single CSV, penguins_lter.csv. A simplified subset penguins_size.csv is also included, which contains four penguin size measurements (culmen length, culmen depth, flipper length, and body mass) for the 3 species, along with island and sex.

Feel free to use the illustrations below for your teaching materials (Artwork: @allison_horst).

From Gorman et al.: "Data reported here are publicly available within the PAL-LTER data system (datasets #219, 220, and 221): http://oceaninformatics.ucsd.edu/datazoo/data/pallter/datasets. These data are additionally archived within the United States (US) LTER Network’s Information System Data Portal: https://portal.lternet.edu/. Individuals interested in using these data are therefore expected to follow the US LTER Network’s Data Access Policy, Requirements and Use Agreement: https://lternet.edu/data-access-policy/."

Anyone interested in publishing the data should contact Dr. Kristen Gorman about analysis and working together on any final products.
