Alex Rogers is a marine biologist working on the ecology and conservation of marine ecosystem. Most of his research has focused on Antarctic and deep-sea habitats, including seamounts, hydrothermal vents and cold-water corals. He uses molecular tools to help investigate the diversity and evolution of species and connectivity of populations of marine organisms. He has also worked extensively on human ...

Her research is focused on the interaction of Scotia Sea species and their links to the circumpolar ocean (from a food web perspective) to understand the importance of spatial and temporal variability in the operation of this ecosystem. Eugene Murphy has spent over 25 years working on polar marine ecosystems, as a marine ecologist and ecological modeller.  His major interests are in the structure and function of oceanic ecosystems, and how biological and physical interactions at different scales affect the dynamics of marine populations, the overall structure of marine ecosystems amd their response to change. Andrew Clarke has spent the over 40 years working in polar regions, principally as a marine ecologist.  His major interests are the elationship between temperature and the physiology and ecology of organisms, and how changes in climate over geological time have influenced the distribution and diversity of organisms.
