Antarctic and Southern Ocean ( ASO ) marine ecosystems have been changing for at least
the last 30 years, including in response to increasing ocean temperatures and changes in the …

Animal telemetry is a powerful tool for observing marine animals and the physical environments
that they inhabit, from coastal and continental shelf ecosystems to polar seas and open …

Polar oceans are poorly monitored despite the important role they play in regulating Earth’s
climate system. Marine mammals equipped with biologging devices are now being used to …

… This conclusion regarding adaptation is strengthened by the vertical move-step-length
frequency distribution of a 2.5-m-long, <1-year-old basking shark that we tracked for 7 months that …

… seals typically dived to ≈200–300 m at night and 400–600 m or more during daylight hours.
… depths were relatively consistent between 200 and 400 m, regardless of the time of day. …

The DNA of prey present in animal scats may provide a valuable source of information for
dietary studies. We conducted a captive feeding trial to test whether prey DNA could be …

… We estimate that about 0.3–0.7×10 6 m 3 s −1 of dense shelf water produced by the Cape
Darnley polynya is transformed into Antarctic Bottom Water. The transformation of this water …

… In Area 2 this range was reduced to 110 m (350-460 m), and in Area 3 it was smaller still (70
m) with the mean depth at midnight being 340 m and at midday being 410 m. Type 2 dives …

Background Determination of seabird diet usually relies on the analysis of stomach-content
remains obtained through stomach flushing; this technique is both invasive and logistically …

Polar regions are particularly sensitive to climate change, with the potential for significant
feedbacks between ocean circulation, sea ice, and the ocean carbon cycle. However, the …
