Nice to see our drifter pictured on the cover of the 10-year summary. We had missed our drifter. With that, that is a wrap folks! Good bye from CARTHE 🥰🌺

CARTHE was created to bring researchers together to study ocean circulation in hopes of better understanding and predicting how currents transport pollutants. This synthesis paper by CARTHE scientists takes a look at just how far we have come since DWH and how our tools can be used moving forward.

Predicting the distribution of oil, buoyant plastics, flotsam, and marine organisms near the ocean surface remains a fundamental problem of practical importance. This manuscript synthesizes progress in this area during the time of the Gulf of Mexico Research Initiative (GoMRI; 2012–2019), with an ...

Happy World Oceans Day!

The theme of World Oceans Day 2020 is "Innovation for a Sustainable Ocean." At CARTHE, we are always looking for new ways to study the ocean and creating new tools to improve our experiments and models. Innovation is key in advancing ocean sustainability. Thank you to all of our researchers, students, and staff for their work to better understand the ocean.

10 years ago today, the Deepwater Horizon disaster claimed the lives of 11 people and spilled 5 million barrels of oil into the Gulf of Mexico. Since then, CARTHE scientists have been tirelessly studying the movement of oil and other pollutants in groundbreaking ways. From Louisiana to the Arctic, from laboratory experiments to some of the largest oceanographic field campaigns ever conducted, from high school students to professors, the CARTHE team has been dedicated to advancing our understanding of physical oceanography.
Today we pause to remember how this all began, the impact on our communities and the environment, and all of our accomplishments over the last 10 years.

A message (and $100) in a bottle left the Bahamas in June 2018 and was found in France recently:

[Presse Océan] Sur une plage vendéenne, une Rezéenne a trouvé début janvier une bouteille en verre contenant un butin étonnant : un maillot de bain, mais aussi un billet de 100 dollars, une photo de femmes qui pêchent.

“Smaller ocean motions are too large to observe in the lab, but too small to observe from space,” explained study author Henry Chang, “This study targets precisely those scales, where material is moved around within minutes to a few hours and across distances of 1 to 100 m.”

Special thanks to the hundreds of students who helped paint plates!

Researchers optically tracked 600 biodegradable bamboo plates floating in the Gulf of Mexico for 2.5 hours to better understand how small-scale currents (scales of minutes and meters) affect surface dispersion.

The mystery of the Brazil oil spill is being resolved.

Following up on a discovery made by Professor Humberto Barbosa of the Federal University of Rio de Janeiro, SkyTruth has looked further into the mysterious slick which appeared 54 km off the coast of southern Bahia, Brazil on October 28th in a Sentinel-1 Radar image. Looking through 58 Sentinel-1 images dating back to November 1st, 2018 in this exact location, SkyTruth was unable to detect evidence of a repeat occurrence of the slick. Wind readings at the time of the scene show consistent gusts from the east-northeast, suggesting that this slick came from a moving vessel. It's also worth noting that we don't see any offshore infrastructure, such as oil platforms or FPSOs, in this area; the slick doesn't appear to originate from a fixed point source. The slick is comparable in size to the long, oily slicks from vessels illegally discharging untreated bilge that we've observed in other parts of the world.

This finding comes amidst weeks of response to an ongoing environmental crisis on beaches stretching far up Brazil's northeast coast, with clumpy oil polluting the region's otherwise pristine beaches. The cause of this disaster has yet to be determined, but SkyTruth will continue to comb through imagery in hopes that the truth will be illuminated.

Interesting work by our scientists from the University of Cambridge

Scientist John Taylor with the University of Cambridge analyzed simulations of small-scale fronts (

Great piece on one of our exceptional graduate students from Brown University!

Predicting where oil will go can be one of the most challenging aspects of marine oil spill response.
