Discovering New Species and Exploring Deep-sea Microbiomes

Traducción al español a continuación Ten to 30 million species are estimated to exist on our planet, yet only ~1 million of these have been formally described. These estimates do not include the vast majority of microbial life, let alone how microbes interact with animals. A major goal of scientific discovery is to understand not … Continued

Fluid Flow through the Crust

Traducción al español a continuación In addition to the biologists studying octopus, the science party on the Falkor (too) includes a geophysicist (me) and a hydrogeologist (Dr. Rachel Lauer).  Our role is to study what is happening beneath the seafloor to understand better the “plumbing” that moves fluids into and out of the ocean crust, … Continued

Starting the Expedition: Serpentinization on the Seafloor

Spanish Translation Below  The origins of this expedition – “Searching for Serpentinization-Driven Hydrothermal Activity on Oceanic Core Complexes of the Mid-Atlantic Ridge” – go back to the year 2000, when a talented team of marine geologists and oceanographers were surveying and exploring an oceanic core complex with the submersible Alvin at the intersection of the … Continued

Biodiverse Borderlands – 4K Highlights – Video Update

“Establishing ecological baselines in the deep sea allows us to track changes over time and better understand the consequences of human actions,” said Chief Scientist Dr. Lisa Levin, a professor of biological oceanography at Scripps Institution of Oceanography. Check out some of the magnificent sights documented by ROV SuBastian during this expedition.  The goal … Continued

Baseline Exploration – Video Update

“Our goal is to learn about the different types of animal and microbial communities that occur off Southern California. We’re actually in exploration mode: many of these areas have not been visited or studied before. Some of them have not even been mapped accurately.” Take a behind-the-scenes look into the #BiodiverseSCB expedition in this video.

WaterWords of the Day: Authigenic

The WaterWord: Authigenic Definition: Although some people are born with a wanderlust, wanting to travel all over, some seem to be ready made homebodies. And rocks that are authigenic are the homebodies of geology. Authigenic means that rock formed where it is currently located. That’s in contrast to rocks that form from materials that were … Continued

WaterWords of the Day: Methanogenesis

The WaterWord: Methanogenesis Definition: Anytime you see the word “genesis,” you’re looking at the beginning of something, and methanogenesis is no exception. It refers to the creation of methane by a specific set of microbes (microscopic organisms) that produce methane as a byproduct of digesting their food. Etymology: Methane comes from the French word methylene, itself made … Continued

Source of the Seeps

Seven days have gone past since we set sail from Astoria, and every day we have looked at these methane seeps. Bubbles, nosy sablefish, half-buried clams, and colorful corals have dominated our ROV feeds from SuBastian. But in this log, I would like to shed a little light on a different aspect of all of … Continued

WaterWord of the Day: Methane Seep

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
