Penguin Poop Is Melting Antarctic Snow by Keeping Algae Green
Scientists found guano-fed green algae absorb 40% more sunlight than clean snow, helping coastal Antarctic snowpacks melt faster, the study said.

Science Writing, 7 Oct (EFE).- Penguins have been placed at the center of a biological chain that is accelerating the thaw in Antarctica, as guano (excrement) is contributing to a greater fertilization of green algae and indirectly to a darkening of the snow that absorbs much more solar energy and [...] The Entrance The Penguins, in the center of a biological chain that accelerates thaw in Antarctica was first published in HolaNews.
Penguin poop is melting Antarctic snow by keeping algae green
Penguin poop is fertilizing snow algae blooms along the Antarctic Peninsula, feeding dense green algae patches along the coastline, a new study shows. These expanding stretches of green snow melt faster than clean, white snow, potentially speeding up the spread of snow- and ice-free areas of Antarctica.
Madrid.- The penguins have been located in the center of a biological chain that is accelerating the thaw in Antarctica, as guano (excrement) is contributing to a greater fertilization of green algae and indirectly to a darkening of the snow that absorbs much more solar energy and accelerates the thaw.A [...] The entry Penguins accelerate the thaw in Antarctica was first published in EFE Green.
Snow algae paint parts of the Antarctic coast green or red and allow the surface to absorb more sunlight. A study of 111 snow samples now shows a connection between the nutrient input by penguins and other seabirds, high phosphate values and green algae blooms. This could further enhance the snow melt in affected coastal areas. Washington (U.S.A.). White snow reflects a large part [...] The article Penguinkot strengthens the snow melt in Antarct…
