Thanks to Satellite Surveys, Scientists Discover 4 Previously Unseen Penguin Colonies

By tracing the traces of feces in Antarctica through satellites, a scientist recently identified four previously undiscovered colonies of emperor penguins. This brings the total number of breeding colonies of this vulnerable species to 66, according to a paper published on January 20 in the journal Antarctic Science.

Scientists Identify New Emperor Penguin Colony in West Antarctica with Satellite Technology.

To identify these colonies, Fretwell combined data collected by the Maxar WorldView-2 satellite imaging monitor and the Sentinel-2 satellite of the European Space Agency between 2018 and 2022. Even from space, scientists can see the brown spots from guano, or penguin droppings. The colonies discovered by Fretwell are likely to have existed for years, he said.

They are mostly small groups, each with less than 1,000 breeding pairs. Some newly discovered colonies are located near other penguin hotspots. One unexplored area is located on the coast of Marie Byrd Land in West Antarctica, about 31 miles (50 kilometers) away from the abandoned Russian research station. While the station was still operational, there were never any publicly announced sightings of emperor penguins.

The translation of the given 'Bahasa' text to 'English' while preserving any html tags is: "Another new colony site is located on the northern side of the Lazarev Ice Shelf, where a larger colony was previously recorded but declared extinct in 2019."

This finding increases the global population of emperor penguins to 5,700 pairs. However, the estimated population of the lost Lazarev penguin colony is around 4,500 pairs, and the new colony appears to be much smaller.

Situs koloni baru lainnya terletak di sisi utara Lapisan Es Lazarev, tempat koloni yang lebih besar pernah tercatat tetapi dinyatakan punah pada tahun 2019. <br>

The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags:

Penguin kaisar adalah spesies penguin terbesar, dengan berat mencapai 100 pon (45 kilogram), hampir sama dengan berat kebanyakan anak laki-laki berusia 13 tahun.

Dengan hanya sekitar 200.000 pasangan penguin yang tersisa di alam liar, mereka juga merupakan salah satu spesies penguin yang paling terancam, dan diperkirakan akan punah pada akhir abad ini.

The Emperor Penguin is the largest species of penguin, weighing up to 100 pounds (45 kilograms), almost the same as the weight of most 13-year-old boys. With only about 200,000 pairs of penguins remaining in the wild, they are also one of the most endangered species of penguins and are estimated to become extinct by the end of this century.

breed in the coldest time of the year throughout the year in Antarctica and raise their offspring in the frozen sea ice layer so that their offspring become adults in the summer. However, the sea ice melts quickly due to warming temperatures, putting this species at risk of extinction.
