Penguins: Studying the World's Ocean Sentinels

Penguins: Studying the World's Ocean Sentinels

Penguins are remarkable creatures. King penguins can hold their breath for 23 minutes and dive over 1,600 feet in their search for food. Magellanic penguins can cover 107 miles a day and as much as 10,000 miles a year. And emperor penguins breed on the Antarctic ice, with the egg incubating for up to 55 days on the feet of a fasting male, at temperatures below minus 40 degrees Fahrenheit in winds up to 90 mph.

Because penguins live most of their lives at sea but return to land to breed and molt, they are gauges of marine health that are accessible to researchers and relatively easy to study. Through these ocean sentinels, scientists can learn about the health of marine ecosystems across the Southern Hemisphere and use this knowledge to develop realistic and effective conservation strategies for the world’s southern oceans.

Data-driven policymaking is not just a tool for finding new solutions for emerging challenges, it makes government more effective and better able to serve the public interest. In the coming months, President Joe Biden and the 117th Congress will tackle a number of environmental, health, public safety, and fiscal and economic issues—nearly all of them complicated by the COVID-19 pandemic. To help solve specific, systemic problems in a nonpartisan fashion, Pew has compiled a series of briefings and recommendations based on our research, technical assistance, and advocacy work across America.

Data-driven policymaking is not just a tool for finding new solutions for difficult challenges. When states serve their traditional role as laboratories of innovation, they increase the American people’s confidence that the government they choose—no matter the size—can be effective, responsive, and in the public interest.
