This review highlights significant gaps in our knowledge of the effects of seismic air gun
noise on marine mammals. Although the characteristics of the seismic signal at different …

The use of satellite tracking for the fundamental and applied study of marine turtles began in
the 1980s but has undergone rapid growth in recent years. To provide a background against …

Many species carry out their most interesting activities where they cannot readily be
observed or monitored. Marine mammals are extreme among this group, accomplishing …

Crabeater seals exhibit extreme dietary specialization, feeding almost exclusively on
Antarctic krill. This specialization has inextricably linked habitat use, life history and …

Elephant seals regularly perform dives during which they spend a large proportion of time
drifting passively through the water column. The rate of vertical change in depth during …

Top pelagic predators such as tunas, sharks, marine turtles and mammals have historically
been difficult to study due to their large body size and vast range over the oceanic habitat. In …

Adélie penguins (Pygoscelis adeliae), carabeater seals (Lobodon carcinophagus),
humpback (Megaptera novaeangliae), and minke whales (Balaenoptera bonaernsis) are …

The development and deployment of logging and telemetry equipment on wide ranging
marine animals has provided a wealth of data on their movements and behaviour. We can …

Species of bird that use their wings for underwater propulsion are thought to face
evolutionary trade-offs between flight and diving, leading to the prediction that species with …

Intra-specific and intra-population variation in movement tactics have been observed in
many species, sometimes in association with alternative foraging techniques or large-scale …
