The SCAR-programme EBA (2004-13) will address the impacts of climate change on species biodiversity, evolutionary adaptations and depletion of marine fisheries on community dynamics in the Southern Ocean. A better understanding of the effect of such changes will be obtained by investigating the acclimatory responses to high latitudes. It will contribute to development of a baseline understanding of sensitive ecosystems.

Aboard Polarstern, bathymetry — the mapping of the seafloor using sonar — is conducted by an international working group. In recent days, they have found a distinct elevation at the seafloor of the Southern Ocean. This structure rises 600 m above ground in an otherwise featureless seascape and is situated about 450 km north of the Antarctic continent. It closely resembles an underwater volcano, presumably still active, which has never been charted on a map. This finding was reported by Elena Pugacheva from the Geographical Institute Moscow and Jan-Hendrik Lott from the University of Karlsruhe. During the expedition, long distances are covered between the continents of Africa, Antarctica and South America. Mapping of the seafloor takes place throughout the journe...

“Polarstern” is currently anchored right next to the ice shelf, which is formed by layers and layers of snow accumulated over thousands of years forming a vertical cliff dropping more than 30m to the sea (surface). Fuel and other goods are being discharged to supply Germany’s Neumayer station in Antarctica. At longitude 8°48' west, this part of East Antarctica’s ice cap is considered stable. The complete opposite is true for the Antarctic Peninsula heading towards the southern tip of South America. This area will form the backdrop for a scientific mission of an expedition that started two weeks ago in Cape Town. During the past 15 years atmospheric warming led to the collapse of major parts of the Larsen A and B ice shelves. These areas together made up only one percent of Antarc...

Matthieu, the subject of today’s log, is our resident scientist. Working for the oceanographic laboratory at Paris-Jussieu University, he is responsible for managing all of the scientific activities on board. Qualified as an engineer in computing and electronics, Matthieu has already spent one year in the polar regions, passing a winter at the French Antarctic base Dumont d’Urville. His tour in the south was as a science technician, responsible for the base computer network administration and the maintenance of various scientific experiments. When asked what led him to the polar regions Matthieu explains it was for a number of reasons. “Mainly for the scientific interest, but also the fact that the French Polar Institute was next to my engineering school when I was a s...

ANDRILL’s website provides a wide range of information and activities from simple interactives, photos and images, videos, interviews and blogs from the field, and hands-on inquiry activities developed by the ARISE teachers, to an explanation of the science of drilling for sediments and developing a paleoclimate record from the evidence found in the sediment core samples. This site includes information on ice sheets and ice shelves, drill rig technology. Educators’ journals from the field in Antarctica explain the science in words and photos for non-technical audiences and children. Teachers can sign up to receive polar science curriculum materials and e-mail updates and link to many other worthwhile websites. Activity: On ...

Several traverses across Antarctica are occurring this season, studying the East Antarctic Ice Sheet. They all have very informative and helpful web pages, as well as daily or weekly updates about their progress. Previous Expeditions: More information on previous International Antarctic Traverses can be found on the following pages: Summary of International Trans-Antarctic Scientific Expeditions (ITASE) Previous scientific traverses across East Antarctica almost fifty years ago Current Expeditions: ...

CAML will investigate the distribution and abundance of Antarctic marine biodiversity, how it will be affected by climate change and how climate change will affect the ecosystem and the planet. Its key focus is a major ship based research programme in the austral summer of 2007-2008. Scientists from 30 countries and 50 institutions will collate data providing a robust benchmark against which future change can be measured.

Sound is an extremely effective means to monitor marine mammals in the Southern Ocean. Sound recording instruments can remain all year, despite the ice and lack of sunlight. These data may provide new insight into how marine mammals make use of the environment.

I thought I was the first Portuguese to study Wandering albatrosses but I was five hundred years too late. When fifteenth-century Portuguese sailors first ventured down the coast of Africa, they encountered large black and white birds with stout bodies, which they called alcatraz, the Portuguese word for large seabirds; English sailors later corrupted alcatraz to albatross. I was studying aspects of their diet and feeding behaviour in ways that could not be done five hundred years ago, information which may help save them from extinction. That made me feel better...

Navigating through the Norwegian fiords has been truly magnificent. With grand mountainous landscapes, winding channels with strong currents, a scattering of fishing villages and the midnight sun we have enjoyed every mile of it. We can see many similarities with the landscapes of Patagonia and South Georgia. At the start of the year we were sailing past the abandoned Norwegian whaling stations in South Georgia. Now the cultural links between the southern whaling grounds and this part of the world are even more evident to us as we sail past small isolated fishing villages that resemble in some ways the Norwegian settlements in the south. For those of us with biological clocks regulated to the mid latitudes we are finding it somewhat bizarre to experience 24 hour sunlight. Vi...
