One of the peninsula’s
delightful little surprises is the southernmost branch of the British Post
Office at Port Lockroy on Goudier Island.
In summer, when it is manned on behalf of the United Kingdom Antarctic
Heritage Trust, it attracts more than 6,000 visitors a year, which makes it the
most popular stopping-off place for cruise ships in the Antarctic. On the beach
is the skeleton of a giant fin whale, a species second only to the blue whale
is size. The skeleton is reconstructed
every spring after the winter storms have demolished it, and it remains a sad
remainder of a whaling industry that almost wiped out the world’s whale
populations during the 20th Century.
Changing
Habitats:
Climatic change is
having an impact on the Peninsula’s penguins.
A colony of emperor penguins has been newly discovered on the sea ice at
snow Hill Island on the eastern side of the peninsula, but a breeding colony on
Emperor Island in Marguerite Bay, on the western side, has disappeared. The western side of the peninsula is one of the
fastest-warming places on the planet, with winter temperatures a massive
6C(10F) higher than just 50 years ago.
Penguin populations have decreased more than 50 percent in the last 30
years. Scientists blame a reduction in
their main food, krill. These
shrimp-like crustaceans graze on algae on the underside of sea ice in early
spring, but with less ice there is less krill, and less krill means fewer
penguins.
