Mapping Land Claimed by Sea Level Rise
Understanding how coastal areas changed as the ocean rose in the past could help communities protect themselves from storm surge flooding in the future as the oceans warm and sea levels rise.

The R/V Marcus G. Langseth: Ocean Explorer
The Marcus G. Langseth, a research vessel operated by Lamont-Doherty Earth Observatory, traverses the world’s oceans conducting marine seismic studies that contribute to new understanding of Earth systems. The ship typically spends half the year or more on research expeditions led by Lamont-Doherty scientists and colleagues from other research institutes.

Imaging the Cascadia Subduction Zone
In the research expedition now underway, we will investigate the Juan de Fuca plate before it disappears under North America to understand why earthquakes happen where and when they do within the Cascadia subduction zone off the Pacific Northwest. Our ship, the R/V Marcus G. Langseth, is one of 25 research vessels available to U.S.…

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.
