On the morning of January 9, 1978, the tanker Brazilian Marina grounded in the Sao Sebastiao Channel, Sao Paulo, Brazil.
Tanks ruptured and spilled approximately 73,600 barrels of Kuwait crude oil.
Approximately 18,000 barrels of the spilled product impacted the shoreline.
Personnel from the United States Coast Guard (USCG) and the United States Environmental Protection Agency (EPA)
responded to the spill at the request of Brazilian Authorities.
Most of the organized shoreline cleanup was focused on the recreational beaches.
Cleanup personnel initially used dispersants to combat the oil on some beaches,
but this proved to have negative ecological effects and was stopped.
The oil was carried to the northeast by the currents.
Approximately 18,400 barrels of the spilled oil impacted the shoreline,
and the remainder drifted out to sea.
Beaches and coastal embayments were oiled in the States of Sao Paulo and Rio de Janeiro.
Six of the beaches of Ubatuba, Sao Paulo were heavily impacted.
Overflights on January 22, showed a 200 square mile slick composed of sheen and some emulsified oil
which remained off Ponta Juatinga for a week, and then began to dissipate.
