Short summary
Is the ocean’s biological carbon pump stable or changing? The Carbon Flux Explorer (CFE), capable of year-long missions without tending ships, was invented to address this question. The CFE dives to 1000 m depths and drifts with currents to optically measure the downward flux of sinking carbon using imaging methods. During wintertime tests in California coastal waters, the CFE observed fluxes ∼10 times higher than previously reported. Traditional approaches have undersampled > 1 mm aggregates.
