Decadal ecosystem response to an anomalous melt season in a polar desert in Antarctica
Amplified climate change in polar regions is significantly altering regional ecosystems, yet
there are few long-term records documenting these responses. The McMurdo Dry Valleys
(MDV) cold desert ecosystem is the largest ice-free area of Antarctica, comprising soils,
glaciers, meltwater streams and permanently ice-covered lakes. Multi-decadal records
indicate that the MDV exhibited a distinct ecosystem response to an uncharacteristic austral
summer and ensuing climatic shift. A decadal summer cooling phase ended in 2002 with …
