Sounds of Antarctica

It is the largest animal on Earth. It can be found in all the world’s oceans and can weigh between 100 and 160 tons, equivalent to the weight of about 15 elephants. It feeds mainly on krill.

The Antarctic minke whale is the smallest of all. As an adult, it can grow up to 11 meters long, and calves reach up to 2.7 meters. It lives in the Southern Hemisphere and its natural predators are orcas. It feeds mainly on krill and is completely gray.

The Polarstern is one of the most advanced and renowned polar research vessels in the world. Operated by the Alfred Wegener Institute (AWI), it has played a key role in scientific exploration of extreme regions. It can break through ice up to 1.5 meters thick.

The crabeater seal is one of the most abundant seal species in the world. Its population is estimated to be in the millions. It has specialized teeth that allow it to filter krill from the water, a unique adaptive trait. It primarily lives on sea ice.

Its scientific name is Ommatophoca rossii and it usually measures between 1.6 and 2.1 meters in length. It is typically found on the drifting ice of the Southern Ocean. Due to its solitary nature and preference for remote areas, it is one of the least observed and studied seals.

It is one of the most iconic Antarctic seal species. Known for its adaptations to extreme cold, it is usually found on fast ice near the Antarctic coast. It dives to hunt prey in deep waters.

They are easily recognized by their large size and distinctive spotted pattern. They are opportunistic hunters and feed on fish, squid, krill, and other seals.

Icebergs typically form when glacial ice flows toward the sea and eventually breaks off into large chunks. It is estimated that about 90% of an iceberg is submerged under water.

They mainly inhabit the coasts of the Antarctic continent and some sub-Antarctic islands. They are excellent swimmers and can dive up to 150 meters deep to hunt for food.

It is the tallest and heaviest of all penguin species, standing between 110 and 120 centimeters tall and weighing between 25 and 45 kilos. It can dive to depths of up to 500 meters.

It is a robust and predatory seabird that belongs to the Stercorariidae family. These birds are known for their aggressive behavior and ability to steal food from other birds, earning them the nickname “pirates of the sky.”

This enigmatic sound is a series of tones and vibrations that cannot be easily attributed to a specific source. It may be caused by a variety of factors, such as ice movement, underwater seismic activity, or poorly understood interactions between marine species.
