The Collaborative East Antarctic Marine Census (CEAMARC) (2007-2008) was a multinational effort to survey the waters north of Terre Adelie
, and George V Land with the intention of producing a benchmark against which future changes to marine life in eastern Antarctica can be studied (Terre Adelie
is the French claim between segments of Australian Antarctic Territory) (Fig.
The disaster for the colony in Terre Adelie
in East Antarctica was down to unusually extensive sea ice late in the summer - despite low ice early in the season - which meant penguins had to travel further for food and the chicks starved.

If global temperatures continue to rise, however, the large colony of emperor penguins in Terre Adelie
in East Antarctica may eventually disappear, according to a study led by researchers from the Woods Hole Oceanographic Institution (WHOI).
Scientists from the Woods Hole Oceanographic Institution in Massachusetts combined information from climate models and forecasts for sea-ice melting with long-term population data from an emperor penguin colony at Terre Adelie
. The results suggested that if greenhouse-gas emissions continue to rise at levels similar to today, penguin numbers will decline slowly until about 2040, after which they will decline significantly more rapidly as sea-ice coverage drops below a usable threshold.
Data gathered at a penguin rookery in Terre Adelie
, Antarctica, showed that when winter sea ice dropped an average of 11 percent for several consecutive years, the penguin population also took a nosedive.
Scientists based their pessimistic outlook on the long-term changes to the number of emperor penguins in a colony living in a part of the Antarctic Peninsula called Terre Adelie
, which has been surveyed regularly since 1962 and has experienced regional warming over the past 50 years.

; Falkland Island Rockhoppers fell ninety percent in less than twenty years; Adelies declined thirty percent in Arthur Harbor, Anvers Island, over a similar period--and these aren't even the endangered ones.
Since 1950, ornithologists in Terre Adelie
, Antarctica, have kept careful track of when nine species of seabirds arrive and lay their first eggs.
