South Georgia’s St. Andrews Bay has a busy beach that’s home to 400,000 king penguins who have converged here to raise the next generation.

More than 1600 kilometers east of the Drake Passage between South America and Antarctica lies the Atlantic island of South Georgia. Here, king penguins live in huge colonies.

However, there is something very special about the comings and goings of king penguins. Tremendous amounts of nitrous oxide, better known as laughing gas, are released via their guano, according to a 2019 study completed by researchers from the University of Copenhagen and their colleagues: here.
