In 2018, scientists pumped 75 kg of red dye into the Atlantic off Martha’s Vineyard; over 36 hours, they found mixing inside the surface layer was about 140 times stronger than across its base
In a striking ocean experiment, scientists released 75 kilograms of rhodamine dye into the Atlantic Ocean south of Martha’s Vineyard, Massachusetts, to watch how water moves and mixes beneath the surface. The experiment, conducted on August 16–17, 2018, showed that the dye spread readily within the ocean’s upper mixed layer but crossed into the denser…
