Oleander Project Transfers to WHOI Management
May 16, 2023
30-year effort to monitor the Gulf Stream and Northwest Atlantic circulation will continue providing crucial data and insights
Woods Hole, Mass. — The Woods Hole Oceanographic Institution (WHOI) is assuming management of the Oleander Project, a 30-year effort to monitor circulation in the Northwest Atlantic Ocean using data gathered from sensors mounted on or launched from a cargo ship that makes regular crossings of the Gulf Stream. Magdalena Andres, an associate scientist in WHOI’s Department of Physical Oceanography will head the effort, which began in 1992 under the leadership of H. Thomas Rossby at the University of Rhode Island Graduate School of Oceanography (URI GSO) and Charles Flagg at Stony Brook University, New York.
“The Oleander Project has provided a glimpse into the workings of a critical part of the ocean over a period of unparalleled change,” said Andres. “The entire ocean science community is indebted to Tom and Charles’s commitment to it, and we are honored to have the opportunity to see that it continues for many years to come.”
The National Science Foundation-funded Oleander Project is named after the cargo ship CMV Oleander, which is operated by Bermuda Container Line and makes weekly trips between Elizabeth, N.J., and Bermuda. Along the way, it crosses the Gulf Stream and other currents between the two ports that together, make up an important part of the Atlantic Meridional Overturning Circulation. This vast oceanic circulatory system influences climate and weather patterns across North America, Europe, and many other parts of the globe and may itself be undergoing change resulting from human impacts on the global climate and ocean system.
The inspiration to put oceanographic sensors on the ship stemmed from Rossby’s realization that scientists on research ships alone could never hope to make the number and types of measurements needed to track changes of such a large region of the ocean playing out over time scales from days to decades. As a result, Rossby and Flagg worked with shipbuilders to incorporate an acoustic Doppler current profiler (ADCP), which measures the velocity of water deep beneath the surface, into the construction of what became the second ship named Oleander. They also worked with the National Oceanic and Atmospheric Administration (NOAA) to add an automated system designed by WHOI engineers to launch expendable bathythermographs (XBTs) that make high-resolution measurements of the upper ocean while the ship was underway.
Today, the third iteration of Oleander is similarly equipped with two ADCPs and an XBT auto-launcher, and together both ships have made more than 1,000 crossings of the Gulf Stream. Data from the project have been cited in dozens of peer-reviewed scientific publications, including a recent paper by Rossby, Kathleen Donohue and Jaime Palter at URI GSO that found the Gulf Stream has slowed somewhat over the past century, likely as a result of changing wind patterns.
At WHOI, the Oleander Project will become part of the Science RoCs (Research on Commercial Ships) initiative, which aims to equip many more commercial vessels with an even wider array of “plug-and-play” sensors to measure physical, chemical, and biological characteristics of the ocean along the world’s major shipping routes.
“Climate change is ocean change, and if we are going to come to grips with what those changes mean for us on land, we need an “all-hands” mentality,” said WHOI Deputy Director and Vice President for Science and Engineering Rick Murray. “Oleander is a shining example of what can be accomplished with this mindset and, more importantly, of how we need to think as we look for solutions to some of our most pressing environmental challenges.”
About the Woods Hole Oceanographic Institution
The Woods Hole Oceanographic Institution (WHOI) is a private, non-profit organization on Cape Cod, Massachusetts, dedicated to marine research, engineering, and higher education. Established in 1930, its primary mission is to understand the ocean and its interaction with the Earth as a whole, and to communicate an understanding of the ocean’s role in the changing global environment. WHOI’s pioneering discoveries stem from an ideal combination of science and engineering—one that has made it one of the most trusted and technically advanced leaders in basic and applied ocean research and exploration anywhere. WHOI is known for its multidisciplinary approach, superior ship operations, and unparalleled deep-sea robotics capabilities. We play a leading role in ocean observation and operate the most extensive suite of data-gathering platforms in the world. Top scientists, engineers, and students collaborate on more than 800 concurrent projects worldwide—both above and below the waves—pushing the boundaries of knowledge and possibility.

- WHOI will assume management of the Oleander Project, which gathers data from sensors mounted on or launched from the cargo vessel Oleander as it makes regular trips between New Jersey and Bermuda.
- Over the 30-year history of the Oleander Project, two ships named Oleander have made more than 1,000 crossings of the Gulf Stream and other currents in the Northwest Atlantic and gathered water velocity and ocean temperature data.
- The project will continue at WHOI as part of the Science RoCS program, which aims to equip commercial vessels with oceanographic sensors to measure physical, chemical, and biological characteristics of the ocean along the world’s major shipping routes.
