If you have ever flown over a coastal area and observed a river meeting the ocean, chances are you have had the opportunity to see a river plume. The patch of distinctly colored water demonstrates the clear continuity of the river flow as it enters the ocean.
The very deepest reaches of the sea are one of the planet’s last true frontiers. In November, RV Falkor sailed to the Mariana Trench with a group of biologists and geologists to conduct a new study of one of the deepest places in the world.
December, Falkor returned to the Mariana Trench focusing on collecting trench bacteria, animal samples, and the first-ever recordings of sounds from such depths.
Perth Canyon is one of Australia’s subsea treasures. Yet many of its deeper reaches remained unexplored, until Falkor’s visit with a deep-diving ROV. This first survey of life in the canyon provided a baseline of deep corals, which will aid in determining the likely future impacts of warming seas and ocean acidification.
At the end of March, Falkor headed to a spectacular, isolated, coral wonder known as Scott Reef. The goals of this project were to improve techniques and algorithms for efficiently coordinating deployments of multiple exploratory vehicles so they can be left unattended to accomplish tasks like detailed seafloor mapping.
AUV Sentry will be used at Hawaii’s underwater volcano, Loihi Seamount, whose base remains largely unexplored. The team will survey and sample the seamount to better understand the dispersion of hydrothermal fluids from Loihi to the Pacific Ocean.
