    Women Making Waves

    There are quite a few graduate students aboard the Langseth but that isn’t anything out of the ordinary. What is a little unusual is that we’re all women, which is remarkable given the demographics of our field. Read on to find out why we’re proud to be making waves in the South Pacific and in…

    Lucky 13 Gets Us 250,000 Years of Sediment

    We have been steaming and searching for locations on the seafloor where the sediments are accumulating undisturbed. We tried without luck to take cores at several promising locations, however the cores came up less than perfect. On our thirteenth core attempt of the cruise we got lucky.

    A Rare Treat – The Green Flash

    Sunday night after successfully recovering a gravity core about 42 miles north of the equator, conditions were right for a rare treat – the green flash.

    Drilling Ancient Mud from Seafloor No Easy Task

    Yesterday we left our first study region with new samples from the seafloor and a healthy respect for the ocean currents that can erode sediment deep in the ocean. The seafloor we surveyed was heavily eroded and we had to look carefully before finding sites that were promising enough to try sampling. Even then we…

    Through the Looking Glass: Peering Through the Bottom of the Ocean

    Alice stepped through the mirror to see the world beyond, and we peer through the bottom of the ocean to see what is below. Short pulses of sound from the ship are focused on the seafloor, and we listen to the echo and reverberations that return.

    Why I Care About the Bottom of the Ocean

    It is the middle of the night and I am wide awake thinking about the ocean, specifically the bottom of the ocean. Is it rocky? Jumbled? Smooth? Rocky is bad. Jumbled is bad. Smooth is good.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
