Macquarie Island ARGOS satellite tracking data profiles the foraging behavior of Antarctic and subantarctic fur seals from 1997 to 1999. The dataset comprises 28 data profiles, capturing location and diving activity. It was collected by the Australian Antarctic Data Centre to study the recovery of seal populations.
Use Cases
- Analyze foraging trip locations relative to the Macquarie Ridge and seal colonies using geospatial tracking points.
- Compare diving behavior and foraging site concentration between Arctocephalus gazella and Arctocephalus tropicalis species.
- Study the relationship between lactation strategy and foraging flexibility using time-series location data over the austral summer.
- Map primary foraging zones, such as areas within 30 km and 60 km north of Macquarie Island, from seal location records.
Strengths
- 28 distinct data profiles provide individual animal tracking records.
- Data covers a multi-year period from 1997 to 1999 for longitudinal analysis.
- Specific foraging locations and distances from colonies are documented in the description.
Limitations
- The sample size is limited to 28 data profiles, which may represent a small number of individual seals.
- Data is temporally stale, with the last update recorded in January 1999.
- Specific column names, data formats, and total row counts are not provided in the input.
