A Résumé on the Oldenburg Climate Symposium
The 2nd Oldenburg Climate Symposium was headlined “Climate, People, Ocean” and was meant to be a multidimensional workshop with offerings to scientists, early career professionals, students, policymakers, and the general public. A safe bet for a successful conference is to give excellent researchers the time to develop their ideas in front of the public. We invited eight speakers from near and far to give their personal perspective on the ocean climate connection.
Did you know?
Unicellular plankton covers a size range that is comparable to the size difference between a small fish and a city like Oldenburg.

57 Days on Board the Polarstern
Bio-acoustician Irene Roca is a postdoctoral researcher at HIFMB. In March and April 2022, she takes part in a research cruise of the FS Polarstern through the Southern Ocean. The expedition starts in Capetown, traverses the Weddell Sea and ends in Punta Arenas in Chile. Logo of the Polarstern expedition “PS129” The mission of the …
Our New Home under Construction
A three-story building with almost 2,000 square meters of floor space will be built by 2023. In addition to 85 office workplaces, the building will also offer around 650 square meters of laboratory space, creating the best conditions for marine biodiversity research.
Undersea Cables: A Reminder for the Highly Wired World and Political Creatures
Lately, people worldwide have been caught off guard from hearing the news about the volcanic seamount eruption in the Tongan sea. This eruption caused tsunami waves—sweeping the Pacific Islands, including Tonga Island. This pacific island nation also suffers from fiber optic cable malfunctions laying on the seafloor, often undisturbed by human activities.
Embracing Tensions in Research, or: Why I Can’t Answer the Question, “What is the ocean?”
Tension. What springs to mind when you think of tension? Images of frustration and anxiety might arise; situations you may not want to revisit, interactions you’d rather forget. As someone who suffers from anxiety and PTSD on a daily basis, it seems counterintuitive for me to argue that tension can be good. But I think it can be.
How Singing Whales Tell us Where They Come From
The humpback whale is probably the most iconic species among the baleen whales. Anyone who listens to Kate Bush knows their long and complex songs. These songs are produced by humpback whale males as a reproductive display, most likely transferring information about individual fitness both to surrounding females and males. Humpback whales accumulate during the winter …
Shade Sails for Coral Reef Recovery
Tropical coral reefs are changing. Some researchers suggest that modern tropical reefs could take the shape of habitat mosaics. Each patch of the mosaic are small patch-habitats of different regime types (e.g. coral-, sponge-, or algae-dominated) that coexist next to each other.
