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
In the hustle that often characterizes the two in-port days before a cruise, it is easy to get lost in the details. Together with my co-chief scientist on this cruise, Dr. Anna Michel, our focus on these details has spanned more than two years of planning, scheming, designing, building, redesigning, rebuilding, testing, ordering, and packing. … Continued
On our last night at sea, I spread my artwork across the two long tables in the library. In a few minutes, members of the science party and crew will file into the room to browse through my work and ask questions about my creative process. I am excited for the opportunity to explain why … Continued
Scientists are always interested where hydrothermal vents are located. However, when a new field is discovered with properties not previously seen, the excitement reaches a whole new level.
When NASA conducts planetary expeditions, they operate the vehicles through remote control – a person on Earth sends commands to the vehicle in space.
Hydrothermal vent and hydrocarbon seeps have been an important subject of oceanographic research over the last 35 years. Nevertheless, there are still many long-standing questions about these dynamic ecosystems, including their distribution and abundance in our ocean.
While methane may not be the best known greenhouse gas, it nevertheless greatly impacts the climate system of our planet. Seafloor methane emissions have been documented for several decades, with newer evidence suggesting that methane bubble plumes from the deep sea are far more numerous than previously assumed.
Life on the Falkor requires a balance of being in the flow and keeping on your toes. I sketch in many breezy corners of the upper decks, observing science operations from all sorts of interesting angles. In the library, I have read an account of Jacques Cousteau, as well as former artist-at-sea Lucy Bellwood’s “Tall … Continued
Conducting research with multiple underwater vehicles takes a huge amount of deliberation and coordination that is based on data gathered well before the work even takes place. But what happens if the environment you work on is constantly changing?
As the third largest port on California’s coast, San Diego Bay showcases the grip of humanity’s hands on the ocean. From our location, we can see the domineering San Diego-Coronado bridge, flanked by multiple aircraft carriers. We watch as commercial shipping vessels loaded down with cargo make their way into port. But for all of … Continued
