Log Post: Hunting Bubbles ~ Week Three Video

Two strategies being tested right now on the #HuntingBubbles expedition include rapid prototyping as well as modifying “off the shelf” sensors and instruments to specific scientific purposes. Take a look behind the scenes and researchers explain their processes and goals.

Log Post: Metals – Key Players in the Past, Present, and Future!

The Earth’s flow of energy – from animals, to plants, to microbes – is dictated by electron transfers: that is, moving electrons from one molecule or element to another in order to gain energy. These types of reactions have dictated the evolution of life on Earth. Photosynthesis is perhaps the most familiar such reaction, where … Continued

This was not what I expected, but then again, I am not sure what I expected. Apart from a one-month stint in undergrad sailing across the Atlantic with Sea Education Association, I have never been on a research cruise before. I knew to expect seasickness to come with the swells and fade with time, to … Continued

Log Post: Hunting Bubbles ~ Week Two Video

This week’s #HuntingBubbles video explains and explores the cutting-edge technology being used on the expedition, including a Mass Spectrometer, Laser Spectrometer, and Stereoscopic High-Definition, High-Speed Camera. Find out how these tools work and what they are revealing to researchers about deep-sea methane seeps.

Many individuals are understandably oblivious to the resources and the teeming life contained below the surface of the ocean. Submarine pilots, marine biologists, and the like are the exception, but the folks who live in landlocked states only know from what they learned in school (and for some that was a long time ago). A disastrous blowout … Continued
