Drifting through the brash ice off Cape Adare, we came across these two Adélie penguins. It was a humbling sight. The two penguins were utterly dwarfed by the massive expanse of the melting sea around them - "marooned on an ice floe", a colleague quipped. Adélies, the smallest of the Southern Ocean penguins, predominately live on sea ice, which makes them particularly sensitive to climate change. As such this image seemed to visually surmise the scale and impact that our marine ecosystems face.
