    Being aboard a ship is isolating—but for a scientist, it’s not lonely.

    It’s Beginning to Look Not a Lot Like Christmas

    Much of the eastern two-thirds of the United States was balmy on Christmas Day, with high temperatures more than 20°F above average from Texas to Maine. According to NOAA, 789 daily high temperature records were tied or broken on Christmas Eve and Christmas Day in the continental United States. What’s behind this unusual weather?

    The Floor of the Ocean Comes into Better Focus

    The bottom of the ocean just keeps getting better. Or at least more interesting to look at.

    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.

    Lamont-Doherty Scientists Create ‘Polar Explorer: Sea Level’

    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.

    Detecting Landslides from a Few Seismic Wiggles

    Over the last six years, seismologists Göran Ekström and Colin Stark have been perfecting a technique for picking out the seismic signature of large landslides. They just discovered North America’s largest known landslide in many years – 200 million tons of sliding rock in Alaska.

    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.

    Testing the Speed of Lava: What It Says about Escape Times & Mars

    Elise Rumpf’s lava flow simulations are yielding new details about the velocity of lava over different surfaces. They may also hold clues about the surfaces of other planets.
