About
Penguin size, clutch, and blood isotope data for foraging adult penguins are included. The data covers three species: Adélie, Chinstrap, and Gentoo. The information was collected near Palmer Station, Antarctica, and encompasses nesting observations, penguin size measurements, and isotope readings from blood samples. This information was originally published in a 2014 PLoS ONE article on ecological sexual dimorphism in Antarctic penguins.
Columns
- studyName: The sampling expedition from which data were collected.
- Sample Number: An integer representing the continuous numbering for each sample.
- Species: The species of penguin.
- Region: The region of the Palmer LTER sampling grid.
- Island: The island near Palmer Station where samples were collected.
- Stage: The reproductive stage at the time of sampling.
- Individual ID: A unique identifier for each individual penguin in the dataset.
- Clutch Completion: A string indicating if the nest was observed with a full clutch of two eggs.
- Date Egg: The date when a study nest was observed with one egg.
- Culmen Length: The length of the dorsal ridge of the bird's bill in millimetres.
- Culmen Depth: The depth of the dorsal ridge of the bird's bill in millimetres.
- Flipper Length: The length of the penguin's flipper in millimetres.
- Body Mass: The penguin's body mass in grams.
- Sex: The sex of the animal.
- Delta 15 N: A measure of the ratio of stable isotopes 15N:14N.
- Delta 13 C: A measure of the ratio of stable isotopes 13C:12C.
- Comments: Additional relevant text information for the data.
Distribution
The data is presented in a tibble format with 344 rows and 17 variables. The data is available in a CSV file named
penguins_raw.csv with a size of 59.94 kB. There are no missing or mismatched values across the 344 records.Usage
This dataset is suitable for exploratory data analysis. It can be used to study the ecological sexual dimorphism and environmental variability within a community of Antarctic penguins. Researchers can analyse penguin morphometrics, such as culmen and flipper length, body mass, and foraging ecology through stable isotope analysis.
Coverage
The data was collected for adult Adélie, Chinstrap, and Gentoo penguins nesting along the Palmer Archipelago near Palmer Station, Antarctica. The temporal coverage spans from 2007 to 2009. Data collection occurred at the "Adult, 1 Egg Stage" of the reproductive cycle. The primary islands for sample collection were Biscoe and Dream.
