Researchers say the Arctic Ocean crossed a biological tipping point in 2009, when nitrate levels in the water suddenly started dropping due to a drastic reduction in sea ice extent.

Scientists say melting sea ice may have pushed the Arctic Ocean past a tipping point, triggering changes that could reshape marine life for decades.
