Indonesian Corals Shed Light on Climate System
A new coral salinity record shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone, influences a major Pacific Ocean current.

All I Wanted for Christmas Was for These Pumps to Work
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.

Setting Sail? Plan for the Unexpected
In the weeks before departing for my first scientific cruise, everyone I knew who had ever been to sea gave me some form of the same advice: Nothing ever works the way you expect it to work at sea.

OUTPACE Cruise: Setting Sail
The OUTPACE 2015 cruise has set sail on February 20! We left port in Nouméa at 8:30 a.m. last Friday morning. I lost sight of land around 10 a.m. or so, and I won’t see it again until we return to port in Papeete, Tahiti on April 3.

Earth’s Climate History, Written in Dust
Dust blowing onto the oceans can help algae grow and pull CO2 out of the atmosphere. It influences the radiative balance of the planet by reflecting sunlight away. Scientists want to know what role this plays in the coming and going of the ice ages, and how it affects our climate.

Clean Water for Fiji
Corporate giant Fiji Water makes millions of dollars every year selling bottled water, but only 47 percent of Fiji Islanders have access to clean drinking water. That may change.
On Saturday, October 17, 2026 from 10am to 4pm, Lamont-Doherty Earth Observatory Open House—our biggest, best science fun and discovery event of the year—will take place on our beautiful campus in Palisades, NY. Mark your calendar and join us for this free, family-friendly celebration of science! RSVP Today!
