Penguin biogeography along the West Antarctic Peninsula: Testing the canyon hypothesis with Palmer LTER observations
The West Antarctic Peninsula (WAP) is home to large breeding colonies of the ice-dependent Antarctic Adélie penguin (Pygoscelis adeliae). Although the entire inner continental shelf is highly productive, with abundant phytoplankton and krill populations, penguin colonies are distributed heterogeneously along the WAP (Ducklow et al., 2013, in this issue). This ecological conundrum targets a long-standing question of interest: what environmental factors structure the locations of Adélie penguin "hot spots" throughout the WAP

A 135,000-year Vostok-Specmap Common temporal framework
International audienceThe object of the present study is to introduce a means of comparing the Vostok and marine chronologies. Our strategy has been to use the •5180 of atmospheric 0 2 (denoted •518Oatm) from the Vostok ice core as a proxy for the •5180 of seawater (denoted •S18Osw). Our underlying premise in using •518Oatm as a proxy for •518Osw is that past variations in •5•8Osw (an indicator of continental ice volume) have been transmitted to the atmospheric 0 2 reservoir by photosynthesizing organisms in th
