Marine research in the Latitudinal Gradient Project along Victoria Land, Antarctica

This paper describes the conceptual framework of the Latitudinal Gradient Project that is being implemented by the New Zealand, Italian and United States Antarctic programmes along Victoria Land, Antarctica, from 72 degrees S to 86 degrees S. The purpose of this interdisciplinary research project is to assess the dynamics and coupling of marine and terrestrial ecosystems in relation to global climate variability. Preliminary data about the research cruises from the R/V "Italica" and R/V "Tangaroa" along the Victoria Land Coast in 2004 are presented. As a global climate barometer, this research along Victoria Land provides a unique framework for assessing latitudinal shifts in 'sentinel' environmental transition zones, where climate changes have an amplified impact on the phases of water.
