Climate models predict that as a result of human-induced climate change, the surface of the Pacific Ocean should be warming. But one key part is not.

Tiny microbes called phytoplankton live beneath the ocean’s surface, producing oxygen that is essential to human survival. A new study sheds light on how these all-important diatoms survive and thrive under difficult conditions.
Now, nearing the end of our three-week cruise of the North Pacific off Hawaii, we are working to understand how these tiny bacteria connect and communicate with one another.
The sea is a deep blue, so clear that you might think it was devoid of life. We have seen only a few seabirds circling the ship and playing in the air currents we generate. We haven’t seen any whales or sharks, only an occasional flying fish taking to the air in front of our bow wake. In this apparent desert, microbial life is king.
Scientists like myself are in a race against time to understand the fundamental drivers of ocean ecosystems before climate change pushes them towards a new unknown state.
Ocean scientists are, in their hearts, explorers. Our group aboard the R/V Atlantis may be more infected with the exploration bug than most. The first goal of our expedition makes that clear: We aim to map regions of the seafloor never before seen by human eyes.
Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.
One of the earth’s newest islands exploded into view from the bottom of the southwest Pacific Ocean in January 2015, and scientists sailing around the volcano this spring have created a detailed map of its topography.
My German colleague and I could conceptualize five kilometers horizontally—the same as her bike ride to work, the same as the first ever race I ran. Neither of us could quite grasp what flipping 5 kilometers 90 degrees might mean, as our pump continued on its 3-hour vertical journey to that depth.
