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 the scientific community at large!

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.

Even then we ran into difficulties getting the sediments back to the ship.

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.
