NASA’s ER-2 airplane recently captured a stunning image of a massive blue melt pond on an unnamed glacier in Alaska. The vibrant blue color of the pond is due to the way the submerged ice absorbs sunlight, creating a striking visual effect.
The melt pond, which is around 2,300 feet across at its widest point, is filled with hundreds of tiny icebergs. While it may appear deep, melt ponds in the Arctic are typically only around 9 inches deep on average. This particular pond stands out as it is isolated, surrounded by miles of snow with no other ponds nearby.
Melt ponds form as the ice thaws in late spring and early summer, pooling water in depressions on the surface. These features have become more common in the Arctic in recent years due to climate change. The dark blue color of the ponds allows them to absorb more sunlight, contributing to the melting of surrounding ice and creating a feedback loop that accelerates the process.
Monitoring melt ponds is crucial for understanding the impact of climate change on the Arctic. The number of ponds that appear each summer can predict the minimum sea ice extent for the year. However, there is still uncertainty surrounding the formation and impact of these ponds, highlighting the need for more research and observation in the region.
Researchers suggest increasing aerial observations of the Arctic and utilizing artificial intelligence to analyze data in order to improve our understanding of melt ponds and their role in the climate crisis. By studying these phenomena more closely, we can better predict and mitigate the effects of climate change on the Arctic region.
