On the Surface, Feeling Further Away from the Ocean than Ever

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.

We’ve just completed our first full station and are remarkably pleased with the results. We collected 8 seawater samples to measure helium isotopes; 20 to measure thorium and protactinium isotopes; 7 in-situ pump filters; 1 box core of the ocean floor; and more.

Doing Science When There’s No Science to Be Done

With an abundance of time and a dearth of work, we have begun to devise ways of doing science before we can actually do science at sea. Among other things, we set up an imaging system to take pictures of particle filters we bring back from the deep sea.

Day 2: What Am I Doing Here, Anyway?

The South Pacific Gyre is the most nutrient-poor region in the ocean, and the waters are the clearest in the ocean. The sediments accumulate below the water at rates as low as 0.1 millimeter per thousand years. So, 10 centimeters of seafloor are equivalent to one million years of material deposition in the South Pacific.
