Trends in Winter Light Environment Over the Arctic Ocean: A Perspective From Two Decades of Ocean Color Data
The last few decades have seen a decrease in Arctic ice cover, leading to changes in the structure and function of marine ecosystems. Yet sustained long-term observations of the marine environment are difficult to acquire. Harsh environments limit in situ measurements, while low light and high solar...
