Cruise: Net Gains at Station ALOHA

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.

Cruise: Deeper Views

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.

Cruise: The Secret Lives of Whales

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.

Cruise: The Iron Eaters of Loihi Seamount

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.

Log Post: The Small Things that Count

And just like that, three weeks has come to an end. As the science team starts to pack up their equipment and explore the data collected, they get their first taste of the water profiles for this region. It seems like just yesterday we were leaving Majuro, Marshall Islands, to begin an 11-day time-series at the equator, but the time has gone by in the blink of an eye.

Person: Estefania Fernandez

Undergraduate student Estefanía is an assistant researcher at the Argentine Hydrographic Service (SHN) of the Argentine Navy. She is involved in projects that investigate harmful algal blooms and the Yaganes Marine Protected Area, located south of Tierra del Fuego Province, Argentina, using satellite data. Currently, as a Physical Oceanography student at the University of Buenos … Continued

Cruise: A Tale of Two Submarine Canyons

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. 

Cruise: Visualizing the Deep off Uruguay

The Rio de la Plata drains into the Atlantic Ocean, delivering sediment-rich contents from the Paraná and Uruguay Rivers, each fed by myriad streams and tributaries. The mixing of fresh water with the nutrient-rich seawater upwelled along the continental shelf fosters remarkable biodiversity. Vulnerable Marine Ecosystems, or VMEs, are critical yet fragile habitats that support a diverse array of species, and human activities pose a significant threat to these ecosystems. Currently, there is only one reported VME in Uruguay. It is home to cold-water coral reefs formed by Desmophyllum pertusum, a slow-growing coral that grows throughout the Atlantic Ocean; experts suspect this ecologically important animal is threatened and in decline. Scientists believe there are more vulnerable ecosystems, but have not had access to the technology needed to describe deep-water areas in Uruguayan waters.

Log Post: Data Storytelling

In September of 2024, Artist-at-Sea Jill Pelto joined the Fire & Ice: Volcanic & Glacial Interaction expedition led by Dr. Sebastian Watt, University of Birmingham, UK. Pelto is an artist and science communicator based in Washington. She was intrigued by the opportunity to study the underwater effects of a 2008 volcanic eruption that dramatically transformed the landscape and lives of the people of Chaitén, Chile. 

Log Post: Mission Possible: Supercomputing at Sea

The 25-day Reef Connections expedition in the Timor Sea has just completed.  Its successful conclusion marks the third cruise this year to use Falkor’s high performance supercomputer. In January, Schmidt Ocean Institute installed a cluster of interconnected high-performance computers on board Falkor, making her the first research vessel with a supercomputing system available to scientists … Continued
