This cruise will focus on the development of safe practices and standard operating procedures for the deployment and operation of remotely operated underwater vehicles (ROVs), as well as for the ROV data and video management and distribution onboard.
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.
In June of 2013, R/V Falkor will be using the hybrid underwater robotic vehicle Nereus, to explore the depths of the Mid-Cayman Rise, which reaches more than 6,500 meters (~4 miles)
Since 1988, oceanographers have been studying a patch of deep blue 60 miles north of Oahu known as Station ALOHA. But despite extensive work there, much remains unknown about the diversity of the area’s zooplankton.
The focus was on inspiring student participants to move toward careers in ocean science, and for those already headed that direction, to provide much needed training for future expeditions.
On the first of three student cruises, the team aboard Falkor answered questions about whales’ decision-making process about how and where whales feed in the deep sea.
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.
Almost all visible life on Earth is eukaryotic. Trees, fish, humans, kelp, flowers, and mushrooms all share one thing: they are built from eukaryotic cells. Unlike prokaryotic cells, eukaryotic cells contain a nucleus and mitochondria, the powerhouses that facilitate cellular functions such as eating, breathing, and physical appearance. Yet, where and how the first eukaryote came into existence is still one of biology’s greatest unknowns. Dr. Brett Baker, of the University of Texas at Austin, and an international team of scientists are working to resolve this mystery.
The Malvinas Current offshore of Argentina — a branch of the Antarctic Circumpolar Current — carries nutrients and cold water from the south, boosting primary productivity in the Southwest Atlantic Ocean. Underwater canyons along Argentina’s continental slope create irregularities in the seafloor that could change the path of this powerful current, facilitating an exchange of water masses between the shelf and the open Ocean. Scientists hypothesize that, as a consequence of this dynamic, massive phytoplankton blooms and biodiversity hotspots are present near the canyon heads in these waters.
