Adelie Penguin Breeding Site Occupancy in East Antarctica, 1950s-Present

A dataset collating observations of breeding Adelie penguin presence or absence at geographic sites across East Antarctica from 37°E to 160°E. It comprises two tables: one listing known breeding sites with names, literature sources, centroids, and comments, and another containing occupancy observations per site and breeding season. The data is sourced from published and unpublished literature and includes survey data from project ASAC 2722, with the record last updated in July 2012.

Use Cases

• Modeling long-term species occupancy trends based on the multi-decade observation records.
• Mapping potential and confirmed breeding sites based on the geographic centroids and site lists.
• Validating remote sensing or survey data against historical literature records mentioned in the description.
• Analyzing breeding site fidelity and colonization patterns across East Antarctica.

Strengths

• Covers a long temporal range from the 1950s to the present day.
• Includes both published literature and unpublished researcher data, suggesting multiple sources.
• Provides geographic centroids for breeding sites, enabling spatial analysis.
• Distinguishes between potential breeding sites and confirmed occupancy observations.

Limitations

• Last updated 2012-07-01 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
