Observations of temporary Forbush decreases (FDs) in the Galactic cosmic-ray (GCR) flux due to the passage of solar storms are useful for space-weather studies and alerts. Here…
The blue whale (Balaenoptera musculus) is a listed endangered species under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. A distinct population of blue whales, the eastern Indian Ocean pygmy blue (EIOPB) whale…
For decades, neutron monitors have been the primary source of ground-level data for studying cosmic rays with rigidities slightly above the geomagnetic cutoff. The NM64 instrument design, the standard for neutron monitors, has been optimized to monitor neutrons produced in atmospheric cascades.
Background: Accurate predictions of animal occurrence in time and space are crucial for informing and implementing science-based management strategies for threatened species. Methods: We compiled known, available satellite tracking data for pygmy blue whales in the Eastern Indian Ocean (n?=?38)…
As the use of coastal and offshore environments expands, there is a need to better understand the exposure of marine megafauna to anthropogenic activities that potentially threaten their populations. Individual satellite telemetry studies are often hampered by small sample sizes…
Pygmy blue whales in the South-east Indian Ocean migrate from the southern coast of Australia to Indonesia, with a significant part of their migration route passing through areas subject to oil and gas production.
Supervised dive classification is a commonly used technique for categorising time-depth profiles of diving … vertebrates. Such analyses permit the description and quantification of dive behaviour and foraging tactics, and highlight feeding locations. Ideally…
Changes in buoyancy during an animal’s time at sea are a powerful tool for inferring … spatial and temporal foraging success. Buoyancy can be difficult to measure, but in some species of … seal, drift components of dives can be used.
