Experts were shocked to find a thick, 60-mile-long "phytoplankton megabloom" under Arctic sea ice, announcing in a study Thursday that ice made thinner by warming temperatures has, for now at least, created ideal conditions for the microscopic, single-cell plants to flourish.

More blooms are likely hidden under the ice, making for "ecological shifts" in Arctic waters that favor some species over others since phytoplankton are the base of the marine food chain, Stanford professor and lead researcher Kevin Arrigo told msnbc.com.

Scientists had thought Arctic phytoplankton blooms only happened after sea ice melted in summer, so the discovery is "like finding the Amazon rainforest in the middle of the Mojave Desert," added Paula Bontempi, who manages the ocean biology program at NASA, which funded the research.

The waters literally looked like pea soup," Arrigo said at a press conference announcing the study in the journal Science. "It was as thick as a 5-year-old child is tall.
