Signy Island data sets revealed a dynamic ecosystem even during an extreme summer, during which there was hardly any melt at all and so the extent and depth of the snowpack changed very little. However, we observed the development of a sub-surface, "patchy" snow algal community at both our sites and our repeat sampling captured this seasonal bloom that remained completely undetectable to the eye when walking over the field sites. We also witnessed extreme chemical and physical conditions in the snow due to the effects of refreezing and the mobilisation of different acids. These chemical conditions will be linked to the microbial consortia functioning at depth within the snow. Significant differences between our two main sites were found due to the different effects of fertilisation from dust and penguin guano.
