This multidisciplinary cruise led by Dr. Carolyn Ruppel of U.S. Geological Survey is studying the hydrate seeps off the coast of Oregon, US. Methane is a dangerous greenhouse gas that bubbles up from these seeps. However, very little methane seeping from the seafloor ever reaches the ocean’s surface due to a process known as aerobic … Continued

The WaterWord: Methane Seep Definition: Ever see a movie set at the bottom of the sea, and notice occasional streams of bubbles coming up from the seafloor? That’s what a methane seep is: A point where methane (a gas) escapes from the rock into the ocean above it. It is one of several types of … Continued

The unusually bright Oregon sun beams down on me as I watch the soaring Astoria bridge recede into the background. The R/V Falkor has just pushed back from the dock and we’re steaming into the great Columbia River. Looking ahead, I can see twin points of land, framing the mouth of the Columbia like a … Continued
The seaborne portion of our expedition has ended, but the land-based search begins. In the laboratory, all the samples are examined with fresh eyes, using instruments that enable Dr. Marc Fries to “see” potential meteorites at a much finer scale. The preliminary examination we performed while on board the Falkor has turned up a few … Continued

Dulai is a geochemist who studies the chemical cycles and distribution of land-based solutes focusing on coastal hydrology, as well as shelf- and ocean basin … Continued
I am quite sure the very first explorers were crazy. Looking out to the horizon and seeing nothing but water, why on earth would anyone ever traverse those endless waves, into the unknown? Of course, it is the same reason that compels us to tackle new problems and learn new things every day: an interest … Continued
After picking up the science team in Astoria, we headed back out to sea! This time we headed northward to the Olympic Coast National Marine Sanctuary off the coast of Washington State. The aim of this leg is to try to locate and recover fragments of a meteor strike recorded off the coast. I have … Continued
