Ocean Acidification

No, the abbreviation of acidification is not AC/DC. Acidification stands for the process that our oceans turn more acid due to the absorption of CO2 from the atmosphere. This has several harmful consequences. Lower calcification, slower growth of corals and mollusks (oysters and mussels) for example, shall reduce biodiversity in the medium term of species with calcium-based skeletons. The UN highlights this in several reports, but action upon this evidence (Ifremer 2026) is slow or even absent. Besides the acidification, the oceans have increasing temperatures. Some researchers frame this process already as the “tropicalisation”, the warming of sea water and migration of fish according depending on their preferred or necessary temperatures of sea water. Some move to cooler water, other species move into or “invade” due to higher temperatures.
This can be observed and studied in citizen science projects across the globe and by tourists with a little interests in what is happening near the beaches. Just take a litmus-strip with you to test the basic or alkaline pH-value of the sea water in a glass of sea water. Then add a bit of soda water and test again. That’s a bit exaggerating, what acidification of oceans is about, but the underlying mechanisms is the same.

Concorde

„These were the days my friends, we thought they’d never end …“ And yet the Concorde served for decades as a massively polluting aircraft for those paying or had their flights paid be their enterprises to cross the Atlantic ocean. Yes it was the fastest way, but we learned that it didn’t really make sense. After a technical default with an explosion the entire craze got stopped. Now next to Orly airport the remainders of this undoubted design highlight is exposed. It serves more as a warning that not all technical innovations are viable as commercial or ecological innovations. The delta-design as aircraft is still the most common design children play around with as paper models. Wing designs have made progress to adapt the bent end on each wing. So should do our paper models of them. The Concorde is also a perfect example to learn from concerning the link between “Society and Technology”. Similar mistakes seem to occur still today. “When will we ever learn, when will we ever learn…”.

Indigo Waves

„Indigo“ is an almost mystical colour. Its deep blue nature refers to profoundness and in combination with oceans to a surprisingly still largely unexplored world of biodiversity. Additionally, in association with endlessly forthcoming and retreating waves, indigo reveals its many possible shades. Oceans separate or link continents and it is this feature of Oceans which is explored in the exposition “Indigo Waves and Other Stories” (Gropiusbau). Beyond our all to common focus on the transatlantic relationships, “Indigo Waves” explores the links between the African and Asian continents. Embarking on a new narrative for the Afrasian Sea, i.e. the Indian Ocean, we are taken to new horizons through the continuous challenge to our value systems, comprehension of art, poetry or culture more generally. The exposition, through multiple challenges, succeeds in displacing us into the context of other perspectives. Following Oscar Murillo, imagine to view the water roses from Claude Monet (Les Nymphéas) from below the surface. What do you expect? In Europe? Near a barrier reef in the Indian Ocean? Beauty is often not visible at first sight, yet it is co-determined by the currents that build and potentially destroy it (compare photo from exhibition below). The balance of social ecosystems is easily messed-up just like the beauty of ecosystems in nature. “Indigo Waves and other stories” tells us other versions of the colonial stories most of our history books told us for centuries. It is an eye-opening exposition, but probably not the way we expect. Following a poem towards the end of the exhibition by Tishani Doshi “Do not go out in the storm”, we are drawn into the ambiguity of our existence irrespective of the continent of origin. Jack Beng-Thi preserves a poem from Jean Joseph Rabearivelo in his artistic book creation and installation to bring to light “indigo waves”. “vos yeux clignotent dans l’azur, et je les appelle : étoiles. ” (Translated suggestion: “your eyes blink in the blue sky, and I call them: stars).
