The climate of the western shelf of the Antarctic Peninsula (WAP) is undergoing a transition
from a cold-dry polar-type climate to a warm-humid sub-Antarctic–type climate. Using three …

Understanding the mechanisms by which climate variability affects multiple trophic levels in
food webs is essential for determining ecosystem responses to climate change. Here we use …

Sea ice and oceanic boundaries have a dominant effect in structuring Antarctic marine
ecosystems. Satellite imagery and historical data have identified the southern boundary of …

The circum-Antarctic Southern Ocean is an important region for global marine food webs
and carbon cycling because of sea-ice formation and its unique plankton ecosystem …

Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and
the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss …

Since the first evidence of low algal productivity during ice ages in the Antarctic Zone of the
Southern Ocean was discovered, there has been debate as to whether it was associated …

Climate change will alter marine ecosystems; however, the complexity of the food webs,
combined with chronic undersampling, constrains efforts to predict their future and to …

It is now widely accepted that global warming is occurring, yet its effects on the world's
largest ecosystem, the marine pelagic realm, are largely unknown. We show that sea …

The climate of the Western Antarctic Peninsula (WAP) is the most rapidly changing in the
Southern Hemisphere, with a rise in atmospheric temperature of nearly 3° C since 1951 and …

We report results collected year‐round since 1998 in northern Marguerite Bay, just inside
the Antarctic Circle. The magnitude of the spring phytoplankton bloom is much reduced …
