  • Extreme Weather Events and Marine Predators Data

    This dataset contains processed weather variables, extreme weather indices, to examine the influence of extreme weather events (EWEs) on the reproductive output of three marine predator species in Tasmania: Australian fur seals, short-tailed shearwaters, and shy albatross. The biological data themselves are not included in this submission, as they are owned and managed by the Marine Conservation Program (MCP), Department of Natural Resources and Environment Tasmania, and the Friends of Maatsuyker Island (FOMI, Wildcare Inc.). Weather information was compiled from the Bureau of Meteorology (BOM), the BARRA2 atmospheric reanalysis dataset, and the CAWCR wave hindcast model. Daily summaries and synoptic observations were used to derive meteorological variables relevant to species’ breeding seasons, including temperature, rainfall, wind, solar radiation, wave energy, and derived measures such as wet-bulb globe temperature (WBGT) and apparent temperature (AT). Extreme weather indices were calculated following BOM definitions, using ≥30-year climatological baselines where available. Percentile-based indices were produced in both binary (occurrence) and continuous (magnitude) forms to characterise heatwaves, rainfall extremes, and other EWEs. The purpose of assembling these weather datasets and code is to provide a transparent, reproducible foundation for analysing environmental drivers of reproductive variability across marine predator species in Tasmania. This resource enables users to replicate the workflow used in the associated publication, and statistical analyses linking environmental extremes to breeding outcomes.

  • Trophic markers of marine predators in the Southern Ocean

    Stable isotope data, fatty acid and diet data was collected from a number of predator species in the southern ocean. Data was collected from blood, blubber, feathers and whisker samples

  • Morphology and breeding data of seal and bird species in the Southern Ocean

    Data collected to measure foraging and reproductive success. Stored as time series data including mass, condition (fat stores), length, girth, offspring survival and growth. Data collected and methodology used varies depending on species.

    Foraging behaviour of birds and mammals in the Southern Ocean

    Raw time series of depth, water temperature, light and swim speed. Stomach temperature and heart rate are available in some instances, but the data is sparse. Data was collected using time/depth recorders and satellite telemetry. Ancillary location was recorded from a separate logger.
