Remote Access Sampler (RAS)

The Remote Access Sampler (RAS) is a deep water or coastal time series water sampler that collects samples for biological, dissolved major and minor nutrient, dissolved trace metal, or dissolved organic carbon analyses.

McLane Remote Access Samplers are designed to collect in-situ water samples in support of oceanographic research projects and environmental monitoring programs. The RAS 3-48-100 and RAS 3-48-500 collect ambient water…

A DISCO in the Ocean

A DISCO in the Ocean

To investigate coral bleaching, WHOI scientists figure out a novel way to take direct measurements in the ocean of superoxide, a key molecule that vanishes almost as soon as it is made.

The Unseen World on Coral Reefs

We have learned that microbial communities on and within us—a microbiome—keep people healthy. Corals reefs also have their own microbiomes that they couldn’t function without.

Sunlight Reduces Effectiveness of Dispersants Used in Oil Spills

Sunlight Reduces Effectiveness of Dispersants Used in Oil Spills

A research team led by Woods Hole Oceanographic Institution (WHOI) found that sunlight chemically alters crude oil floating on the sea surface within hours or days. In a follow-up study the team reported that sunlight changes oil into different compounds that dispersants cannot easily break up. The results of these two studies could affect how responders decide when, where, and how to use dispersants.

Mission to the Ocean Twilight Zone

Mission to the Ocean Twilight Zone

The twilight zone is a part of the ocean 660 to 3,300 feet below the surface, where little sunlight can reach. It is deep and dark and cold, and the pressures there are enormous. Despite these challenging conditions, the twilight zone teems with life that helps support the ocean’s food web and is intertwined with Earth’s climate. Some countries are gearing up to exploit twilight zone fisheries, with unknown impacts for marine ecosystems and global climate. Scientists and engineers at Woods Hole Oceanographic Institution are poised to explore and investigate this hidden frontier.

Did Dispersants Help Responders Breathe Easier?

Did Dispersants Help Responders Breathe Easier?

Seven years after the disastrous Deepwater Horizon oil spill in the Gulf of Mexico, the decision to inject chemical dispersants into the deep ocean has remained contentious. New evidence reveals an unexpected benefit.

Dispersants Improved Air Quality for Responders at Deepwater Horizon

Dispersants Improved Air Quality for Responders at Deepwater Horizon

A study published Aug. 28, 2017, in the Proceedings of the National Academy of Sciences adds a new dimension to the controversial decision to inject large amounts of chemical dispersants immediately above the crippled oil well at the seafloor during the Deepwater Horizon disaster in 2010. The dispersants may have significantly reduced the amount of harmful gases in the air at the sea surface’”diminishing health risks for emergency responders and allowing them to keep working to stop the uncontrolled spill and clean up the spilled oil sooner.

Pop Goes the Seafloor Rock

Pop Goes the Seafloor Rock

WHOI scientists used the human-occupied submersible Alvin and the autonomous underwater vehicle Sentry to explore a surprising discovery: gas-filled volcanic rocks on the seafloor that “pop” when brought up to the surface.

Back to Bikini

Back to Bikini

WHOI scientists returned to the Pacific islands of Bikini and Enewetak in 2015 to study radioactive contamination nearly 70 years after the U.S. used the islands for nuclear weapons testing. What they learned could also be applied to a more recent nuclear disaster: the 2011 Fukushima Daiichi reactor meltdown in Japan.
