Seeing Through Turbulence to Track Oil Spills in the Ocean

by Guillermo García-Sánchez, Ana M. Mancho, Antonio G. Ramos, Josep Coca and Stephen Wiggins 18 August 202225 January 2023

After oil and tar washed up on eastern Mediterranean beaches in 2021, scientists devised a way to trace the pollution back to its sources using satellite imagery and mathematics.

Data from the J-OFURO3 satellite product showing monthly sea surface temperature variations across the global ocean. The red colors indicate sea surface temperature swings from month to month that are typically larger than 1.5°C, while dark blues and purples indicate variations that are typically smaller than 0.5°C.
