WHOI engineer Marshall Swartz (right) instructs Louis Clement, a post-doctoral scientist at the Lamont-Doherty Earth Observatory, on the technical intricacies of a CTD rosette equipped with a lowered acoustic doppler current profiler (ADCP). […]

WHOI Summer Student Fellow Astrid Pacini captured a serene midnight sunset on a research cruise off Iceland in August. Pacini went as an ADCP (Acoustic Doppler Current Profiler) […]

Jian Zhao from the Lamont-Doherty Earth Observatory (LDEO) takes water samples from a CTD (conductivity, temperature, depth) rosette on board the research vessel Nathaniel B. Palmer during a 2015 […]

A scientific instrument called a CTD (conductivity, temperature, depth) is pulled up to the research vessel Nathaniel B. Palmer from deep in the Atlantic Ocean. The 2015 expedition led […]

The world ocean circulates like a conveyor belt, with cold, salty, dense water in the North Atlantic sinking beneath the surface. But one question remains a mystery: How do […]

Deep waters don’t run still, they are moved by currents, turbulence, and “internal waves” that cannot be seen at the surface. In a landmark experiment in the mid-1990s, WHOI […]

Scientists Amy Bower of WHOI and Susan Lozier of Duke University have used RAFOS floats to investigate the Deep Western Boundary Current (DWBC), a deep current that hugs North […]

WHOI scientist Krista Longnecker built this small-scale electrodialysis system to remove salt from seawater collected during the DeepDOM reseach cruise in the spring of 2013. […]

Well-wishers gathered on the WHOI dock in 1952 to bid farewell to the 179-foot research vessel Albatross III, which made 128 science cruises in the North Atlantic. After serving as […]

Author Dallas Murphy (left) and WHOI post-doc Benjamin Harden confer on the bridge of R/V Lance recently about the day’s outreach activities during a cruise in the Arctic Ocean. Murphy […]

Many people consider the porch at Walsh Cottage at WHOI to be a sacred place. Each summer since 1959, some of the greatest oceanographers, physicists, and mathematicians have gathered […]

WHOI post-doctoral scholar Ben Harden waits to capture a dramatic moment at sea: A mooring anchor, released off the stern of the British research ship James Clark Ross, sinks […]

A Subsurface Mooring Operations crew on a cruise to Line W recovers a buoy that collected data for the Access to the Sea program. Named in memory […]

Data from a Nortek DW Aquadopp current monitor is downloaded and analyzed after the instrument spent two years in the Atlantic Ocean south of Greenland, where important subsurface currents cross […]

WHOI technician Steve Murphy prepares a mooring to be lifted off the deck of the British icebreaker James Clark Ross into the water in August. Murphy was part in one […]

In the second of two cruises to study the movement of dense water flowing through the Denmark Strait, WHOI oceanographer Bob Pickart returned to the East Greenland coast this […]

Under a full moon in May 2012, R/V Atlantis stopped in the North Atlantic to lower a rosette samper with a CTD sensor into the ocean as part […]

In August 2011, research vessel Knorr left Iceland for the Denmark Strait to deploy a dozen moorings that will be collected one year later. Instruments on the moorings […]
