Records detail Adelie penguin foraging trip durations at Bechervaise Island, Mawson. Data includes average male and female trip durations during the guard and creche breeding stages, derived from tagged birds crossing an automated monitoring system. The dataset was compiled by the Australian Antarctic Data Centre as part of ASAC Project 2205, with records beginning in the 1991-92 season.
Use Cases
- Analyze the relationship between 'Year' and 'trip duration (hours)' to study long-term changes in foraging effort.
- Compare 'Mean' trip durations between male and female penguins during the 'guard' stage to assess parental investment roles.
- Use 'standard error' and 'standard deviation' values to evaluate the statistical reliability of reported average foraging times.
- Model energy expenditure by combining 'trip duration' data with known travel distances from nest census records.
- Investigate seasonal breeding phases by contrasting aggregated metrics for the 'guard' versus 'creche' stages.
Strengths
- Time-series data spans from the 1991-92 season, providing over a decade of observations.
- Data includes calculated statistical metrics (Mean, standard error, count, standard deviation) for analysis.
- Records are filtered for birds known to be foraging for a live chick, improving behavioral relevance.
Limitations
- Exact row count is unknown, limiting assessment of statistical power.
- Geographic scope is limited to a single island site (Bechervaise Island, Mawson).
- Data appears stale, with the last update recorded in February 2005.
