Why has part of the ocean near California turned pink?

This weekend a team of researchers from the University of California launched a scientific experiment on a beach off the coast of Torrey Pines, in which freshwater currents interact with areas where waves break. ie in surf areas.

The study, titled ‘Plumes in Nearshore Conditions’, is being conducted at the mouth of Los Peñasquitos Lagoon, located within Torrey Pines State and Natural Reserve. The liquid used for the experiment is an eco-friendly pink dye that respects the environment and is supported by the authorities.

Since this weekend, Torrey Pines’ waterfront has presented a strange pink color, which has attracted the attention of onlookers and pedestrians. Researchers have colored the coastal waters of the region, and contrary to what many people believe, it is not a chemical harmful to the ocean.

According to the Scripps Institution of Oceanography at the University of California, San Diego, it is about a scientific experiment called ‘Plumes in Nearshore Conditions’, which aims to explore the interactions between small freshwater flows and Torrey Pines surf areas.

The pink pigment used by the scientists makes the freshwater finches easily trackable using drones or ground sensors. In addition, the team also has submerged sensors that measure wave height and water temperature and a jet ski equipped with a fluorimeter.

Sarah Giddings, an oceanographer at UC San Diego’s Scripps Institution of Oceanography who is leading the experiment, said she was excited “because the research hasn’t been done before and it’s a really unique experiment.” The study was done this weekend and will be done again in early February.

“We will combine the results of this experiment with an earlier field study and computer models that will allow us to advance our understanding of how these plumes spread,” said the oceanographer. The experiment is funded by the National Science Foundation in collaboration with the University of Washington.
