Hearing in Penguins – Antarctic Expedition
In the Antarctic, penguins are exposed to extremely loud environmental sounds such as powerful storms or glacier calving, but also to more quiet sounds such as the vocalizations of their chicks or the distant sounds produced by large marine mammals underwater. As part of the research project ‘Hearing in Penguins’ led by the German Oceanographic Museum in Stralsund, Dr. Michaël Beaulieu will travel to the Antarctic Peninsula to make an inventory of the environmental sounds experienced by penguins both in the air and underwater.
The study 'Hearing in Penguins' is funded by the German Environment Agency (UBA) with means of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU).
„We have reached the South Shetland Islands after crossing a very quiet sea. The landscape is here more and more sub-antarctic, as the rocks surrounded by ice become more and more present and they are even sometimes covered by colorful moss and lichens.
Penguins are still present and I was able to record again their vocalizations on different colonies. After one day in Yankee Harbour and a night close to Half-Moon Island, we then followed the South coast of the South Shetlands to reach Maxwell Bay. We were expected to fly back to South America from there the next morning. However, the lack of visibility due to a thick fog prevented the plane from landing on time.
This is how Antarctica is: unpredictable.
After waiting the whole morning on the boat and almost two hours outside in a chilly atmosphere, the weather finally became clearer and the plane could land. It was time to say goodbye to Ocean Tramp and its crew, and to the few chinstrap and Adelie penguins present there.
The flight between Maxwell Bay and Punta Arenas was surprisingly short (ca. 2 hours) compared to the four days we had to spend on the boat between Ushuaia and Antarctica. Given the rough waves that I could see from the plane, I was happy to fly back and not sail back to the civilized World.
Now, I will stay some days in Punta Arenas before flying back to Germany. However, I am not entirely done with penguins: I will go tomorrow to a colony of Magellanic Penguins located on Magdalena Island, not very far from Punta Arenas.
See you soon in Germany!“
Happy new year from Dr. Michaël Beaulieu from Antarctica!
„The end of 2018 was very busy with the recording of the vocalizations of Gentoo penguins in six different locations along the Antarctic Peninsula. I could also measure the vocalizations of Chinstrap and Adelie penguins in two different locations.
The voice and the behavior of the three species is strikingly different with the Gentoos being more relaxed and more melodious while the chinstraps are more aggressive and sing with a more metallic voice. Adelies are in between. It is also amazing to see how the three species share the same islands to breed, and altogether form an orchestra playing a loud and more or less harmonious concerto.
After several unsuccessful attempts, I was also finally able to record the voice of singing humpback whales swimming around the boat. This was an amazing moment that I could share with all the passengers of Ocean Tramp. We have also seen a group of orcas, but they were too quick to measure their vocalizations.
Yesterday, we had the opportunity to visit the Chilean Station O’ Higgins with the highest level of hospitality from our hosts, before celebrating new year’s eve onboard Ocean Tramp.
We are now leaving the white continent by crossing the Bransfield Strait to reach the South Shetlands tomorrow.“
After celebrating Christmas on board Ocean Tramp, Dr. Michaël Beaulieu is now travelling from spots to spots along the protected East coast of Anvers Islands:
„Two days ago, we tried to go further than 65° South but the passage was stuck with ice and we had to go back to the North.
With the help of the passengers, I have also started to record penguin vocalizations close to Cuverville Island, Brown Base and Port Lockroy. For the moment, I have mostly recorded vocalizations of Gentoo penguins and of some Chinstrap penguins breeding in the same colonies as Gentoo penguins. I am now looking forwards to conducting measurements on a colony of Adelie penguins. Gentoo penguins are now starting to have chicks but most of them are still incubating.
We have also seen humpback whales (verry quickly) and leopard seals on sea ice but no orcas yet.
We have also visited the UK heritage Antarctic station Port Lockroy to see the conditions under which the Brits overwintered 60 years ago. We are now sailing North between Anvers Island and Wiencke Island.“
After four days at sea (and of seasickness) between Ushuaia and Antarctica, Dr. Michaël Beaulieu finally arrived yesterday morning (22nd December 2018) in the Archipelago of Melchior Islands in a foggy and mysterious atmosphere.
„Everybody on board is relieved. A first chinstrap penguin was already waiting for us on a small rock close to the boat. However, this was the only penguin we saw, as the place ist mostly inhabited by crabeater and Weddell seals, Antarctic terns, shags and kelp gulls. I tried to make some sound measurements underwater with my hydrophone while we were going out on the zodiac but could not detect any sound in the shallow waters surrounding Melchior Islands. This place is still a peaceful place for animals living here, although two other small sailing boats have also anchored here for the night,
We are heading today to Port Lockroy where we should see our first colony of gentoo penguins.
Greetings to Germany and happy Christmas!“
Dr. Michaël Beaulieu has been in Ushuaia since 14 December and is preparing for his start in Antarctica:
„I have now been in Ushuaia for two days and the town is wonderful, even though there are (too) many tourists. I went to 'Ocean Tramp' this morning and discovered where I will leave in the next weeks and with who. As you can see from the pictures, even though space is limited, the boat is well equipped and comfortable. People on board are from different countries (UK, France, Germany, Israel and US) and are all very nice. We now have to wait for the wind to calm down before we can leave (hopefully tomorrow).
Greetings from Ushuaia“
On December 12th, Dr. Michaël Beaulieu, project coordinator of the research project 'Hearing in Penguins' in Stralsund, will start his journey to Antarctica. From Germany, he will first travel by plane to Ushuaia in Argentina before reaching the Antarctic Peninsula by boat. This exploration tour was indeed made possible by 'Quixote Expeditions' owning the sailing vessel 'Ocean Tramp' built for high latitude seas, and bringing every austral summer tourists and scientists from South America to the Antarctic Peninsula. Such a journey requires a thorough preparation for the scientist regarding the equipment to bring. Among other things, his equipment includes cameras, microphones and a hydrophone in order to conduct sound recordings in the air and underwater. Such relatively small devices fit perfectly well onboard “Ocean Tramp” where space is obviously limited. Because this expedition will occur during the austral summer, Dr. Michaël Beaulieu will not have to undergo excessively low temperatures but rather temperatures expected to range from -5 to 5ºC.
