Of all the Earth’s habitable zones, the deep midwater environment
This expedition is the first of two research cruises aimed at advancing the tools available to deep-sea scientists to explore and describe midwater biology. A multidisciplinary team comprised of four institutions (University of Rhode Island
Beyond Invention - Real World Testing
Our first expedition is largely focused on the integration and operation of MBARI’s DeepPIV (particle image velocimetry) system
For this Falkor expedition, we have integrated MBARI’s DeepPIV instrument onto ROV SuBastian to conduct 3D visualizations of midwater invertebrates. DeepPIV uses a laser to illuminate a thin sheet of water, mucus, or gelatinous tissue, and captures the illuminated sheet using a dedicated camera. We also use this instrument to study animal kinematics and the way animals use and modify water flow to their advantage. Because of the rigorous resolution requirements of these measurements, collecting quality data (especially in midwate) is very challenging. For example, prime DeepPIV targets include giant larvaceans
Just The Start
After two days onshore mobilizing and integrating our equipment on SuBastian, we have had two successful dives off the coast of Oahu. The success is due largely in part to the dedicated pilots and engineers on the ROV Subastian team who embraced tackling this challenging operation. We have several more exciting days ahead, and then it is time to head back to the lab - to prepare for our next, extended expedition in late 2020 onboard the R/V Falkor. Stay tuned!
