NASA | Massive Phytoplankton Bloom Discovered Under Arctic Sea Ice

A massive phytoplankton bloom was discovered in the Arctic, captured on video by NASA's ICE Skate mission. The bloom, mainly composed of diatoms, extended over 60 miles and was found in the Chukchi Sea. Previously thought to occur only in ice-free waters, the bloom's presence under thinning ice suggests increased sunlight penetration due to climate change. This discovery prompts scientists to assess the impact of these blooms on carbon dioxide levels and climate change.
