Andy’s research largely takes places in Svalbard and Antarctica, but he has also worked in Greenland and northern Sweden. His work considers the implications of ground thaw and ice melt for the release of water, sediment and nutrients into runoff. Particular attention is given to glacier hydrology and how the sensitive ecosystems found at the ice margin are influenced by meltwater dynamics. He also looks at the microbial ecosystems within the ice itself, since there are fewer habitats more vulnerable to the impacts of climate warming than ice and snow.
