This expedition will feature exploration of the Emperor Seamount Chain while researching biodiversity and its drivers. Using currents, mapping, and radio isotopes to track water masses – as well as genetic sampling of corals – the team will determine the driving force behind coral distribution in this region.
The deep sea is home to a variety of understudied, otherworldly ecosystems that are in need of human understanding if they are to have any protection from encroaching deep sea fishing and mining activities.
As we steam towards San Francisco in rough seas, I am reminded how lucky we have been during our time on the Falkor with the weather, never losing any days to poor weather. Falkor really is the luck dragon! I have been at sea now for 27 days, and during this time we have deployed an … Continued
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.
