The Ocean Twilight Zone’s crucial carbon pump

Ken Buesseler

When CO₂ enters the ocean, where does this heat-trapping gas go? WHOI geochemist investigates how much carbon from the surface ocean is dispatched to the ocean twilight zone–the midlayer of the ocean–and on to the deep ocean.

Ocean acidification gets a watchful eye in New England aquaculture ‘hot spot’

Shells

Shellfish aquaculture is thriving in New England, but future growth in the industry could be stunted as coastal waters in the region become more acidic. Researchers at WHOI have developed a way to link nutrient load reductions to improvements in the health of Buzzards Bay, Massachusetts, which may an important step toward cleaner and less acidic harbors in the Baystate.
