Protectors of Antarctic seas
The Commission for the Conservation
of Antarctic Marine Living Resources is
made up of the European Union and 25
countries, including Argentina and Chile. The proposed reserve (mapped above)
would have similar protections as those
the commission ratified for the Ross Sea
Region Marine Protected Area in 2017.

Vital breeding grounds
Four species of penguins and two seal species have long come to the coast of
the western Antarctic Peninsula to breed.
Censuses of nesting penguins record
drastic losses—somcolonies are down by half since 1970—that e chinstrap and Adélie
scientists link to warming temperatures.
Shrinking ice
During the past 50 years, ice shelves along
the Antarctic Peninsula have calved into the sea, often in tabular icebergs—a loss
of more than 11,000 square miles of ice.
Warming seas accelerate the breakup of ice
that seals and birds need for rearing young.
