Adélie penguin populations are of concern to scientists because their numbers have declined in certain parts of the planet even as populations elsewhere have increased. Understanding such changes provide indications about changes in the Southern Ocean or what the penguins eat. While it is surprisingly unknown to many people, much of what we know about Earth’s weather, climate, oceans, ecosystems, and cryosphere is because of long-term or innovative satellite observations from NASA’s Earth Science Division. The Adélie are good “penguins in a coal mine” and are early-warning indicators of threats to Antarctica ecosystem. A NASA Applied Sciences-funded research group from Stony Brook University has been leveraging the workhorse Landsat satellite program to monitor how Adélie penguin diet has changed in response to climate change. NASA’s press release this week points out,

Over the last few years, Lynch and other scientists have been using satellite data to track the distribution and abundance of penguins across the barren landscape of Antarctica. An initial global survey for Adélie penguins turned up 3.8 million breeding pairs. Landsat imagery has since uncovered several previously unknown massive penguin populations. The satellite images can’t see the penguins individually, but it can detect their presence by the stain left on the ice by their excrement—called guano.

Stony Brook University associate professor Heather Lynch is one of the investigators that presented results at the American Geophysical Union annual meeting in Washington D.C. She reveals in the NASA press release that “male and female penguins take turns incubating the nest. The guano left behind builds up in the same areas occupied by the nests themselves…” The scientists backtrack from the guano stains to estimate how many birds were there.

The electromagnetic spectrumNASA

Because the Landsat satellites, through a NASA and U.S. Geological Survey (USGS) partnership, have been operating for four decades, there is a long-term record of penguin guano and indirect assessment of what they are eating. So how does a satellite detect penguin poop? According to NASA,

Landsat data can detect the color of the penguin guano, which the team used to determine what was on the Adélie’s menu. “Penguin guano ranges from white to pink to dark red,” Lynch said. “White guano is from eating mostly fish; pink and red would be from eating mostly krill.”

A quick remote sensing tutorial is needed at this point. Landsat exploits the electromagnetic spectrum (above). The instruments on board the satellite measure reflected light. Different surfaces reflect different types of light. The graphic below explains why tree might appear green to the satellite instrument (and your eyes).

Researchers report long-standing hypotheses that variations in diet explains changes in the Adélie penguin population may need to be reconsidered. They found changes in the physical environment but no consistent pattern in dietary changes. Casey Youngflesh, a graduate student from Stony Brook University, said

these findings are important for our understanding of how the Antarctic ecosystem functions and how this system might change in the future…Given continued changes in the physical environment and a growing krill fishery in the region, changes are likely to be seen both in the availability of penguin prey and penguin populations themselves.”
