AGU Fall Meeting: spying on penguin diet from space

By John Mac, December 15, 2018

In 2014 pink guano residues that revealed up in Landsat images showed that some 1.5 million Adélie penguins go over the Danger Islands from the Antarctic Peninsula in a previously anonymous invasion. Scientists purchased exactly the particular shade of pink to investigate what exactly the penguins take in. Adélie penguins in Antarctica’s west tend to consume krill even though those from the east prefer fish, also as Casey Youngflesh of this college of Connecticut in-depth in the AGU Fall Meeting at Washington DC at a press conference.

Youngflesh collected guano samples and examined them “that a tiny unventilated place in the gut of the boat”, as he advised journalists. “It’s really smelly.” Chemical investigation of each sample showed that which the birds were consumed, enabling Youngflesh to connect penguin diet data and the coloration of guano together.

Images from your satellite archive signals the penguins haven’t shifted their daily diet over time. It truly is likely that these gaps are since you will find fewer Antarctic silverfish close to the Antarctic Peninsula, perhaps. Youngflesh is ongoing investigations on this front.
