a A group of scientists They poured 500 liters of liquid dye That turned the waters of Halifax Bay pinkEastern Canada, forming a circle with a diameter of 500 metres. The result was an eye-catching pink spot Tufts CoveIt spread along the coast, startling passers-by, and then disappeared.
The reason for the dropout was not a joke by students Dalhousie Universitynor a work of art inspired by ‘Barbie’. But curious an experience Conducted by researchers to combat the effects of climate change.
A pink patch in Halifax Bay
The aim of the experiment was to combat global warming. The researchers wanted to test a new way to create… Superconductor at room temperature. To do this, they used Special liquid Contains Nano-metric particles Which aligns under the influence of a magnetic field.
By pouring the liquid into the sea, scientists hoped to create a living organism Superconducting ring It can transmit electricity without resistance or loss of energy. In practice, the pink liquid remained visible in the water for several hours, until its concentration gradually dissipated in Bedford Bay.
The dye they used was… Rhodamine and TIt is a soluble dye that scientists have used for decades to study dispersion And the Flow of aquatic systemsSuch as rivers, lakes, underground sources, or, in this case, the ocean. Dalhousie experts have also used autonomous boats, drones and underwater vehicles to do this Behavior monitoring From the pink spot in the following days until it dissolves in the sea.
The purpose of this leak was Contribute to this planet. More specifically, he showed us new ways to do so Stop climate change. What the Canadian researchers have done is gain experience with tests that will be conducted between September and October using the technology they created Planetary technologiesa company specializing in climate technology.
Its goal: to increase the oceans’ ability to capture and store carbon dioxide (CO₂), a greenhouse gas that must be reduced in the atmosphere.
What are they trying to achieve? Increasing ocean alkalinity. Researchers they suggest Disperse a substance “slightly alkaline” Which enhances the ocean’s ability to capture and store carbon dioxide from the atmosphere.
At Dalhousie, they equate it with him Antacids What to eat after eating a lot for stomach acidity:
“This method, is called enhancing ocean alkalinity or OAEis one of many being studied given the need to achieve net-zero greenhouse gas emissions by 2050.
The purpose of the dye is Verify practice with theory. The researchers would like to have all the means at their disposal so that, when they run new tests with the alkaline solution in the fall, they can check exactly whether they The suggestion works or not.
“This dye tracking study will allow us to determine how quickly wastewater spreads, where it travels within the port, and whether our model predictions of water dispersion and movement are accurate.”
doctor Katja FennelOceanographer.
When the planetary experts deploy their alkaloid in Halifax Harbor in September or October, they will try the dye again so… Monitor the movement of modified water Most importantly, accurately measure the amount of additional carbon being absorbed from the atmosphere.
