Cruise: Deep-Sea Expedition Leadership Master Class

The closest human beings to the Research Vessel Falkor (too) during this expedition might be orbiting the Earth on the International Space Station. The South Sandwich Islands is one of the most remote island chains in the world. It is a volcanic archipelago created by the South American Plate subducting beneath the South Sandwich Plate. Situated between the Southern and Atlantic Oceans, these islands are part of a rich mosaic of tectonic forces that create geologic features such as hadal zone trenches, underwater volcanoes, and spreading centers. These features facilitate high levels of endemism, supporting species found nowhere else.

This Nippon Foundation-Nekton Ocean Census Flagship Expedition will be led by Dr. Michelle Taylor, president of the Deep-Sea Biology Society and Senior Lecturer at the University of Essex; her team will locate and describe new species. Dr. Jenny Gales will lead GoSouth, a collaboration between the University of Plymouth, GEOMAR, and the British Antarctic Survey; her team will survey volcanic flanks with ROV SuBastian to determine the impacts of volcanism and earthquake activity on marine ecosystems. The science teams will also seek out deep-sea volcanoes and venture into the 8000-meter-deep South Sandwich Trench, the most geographically isolated and coldest trench on Earth.

Cruise: Into the Southern Ocean

Research and conservation in the Southern Ocean has never been more urgent. The region is home to some of the planet’s most bio-abundant marine ecosystems, including 10,000 endemic species. It occupies a quarter of the global ocean surface and plays an outsized role in regulating the Earth’s climate systems, absorbing 40% of anthropogenic carbon emissions and 72% of excess heat in the atmosphere yearly. The Southern Ocean’s biological systems largely enable this remarkable climate regulation. However, only 5% of the Southern Ocean is protected, and much of it remains understudied.

The Antarctic Peninsula, which borders the western edge of the Weddell Sea, has undergone some of the most rapid warming of any area on Earth, driving a massive loss of ice on land and at sea. This loss of ice coverage is reshaping the Weddell Sea’s marine communities by opening up newly ice-free areas for species to colonize and inhabit. However, scientific understanding of how Antarctic marine life is responding to this unprecedented warming is minimal. 

Cruise: Climate Connections at the Ice-Sea Interface

In austral summer, the Antarctic sea ice recedes, allowing scientists to map and study parts of the seafloor typically covered in ice. But the waters surrounding the Antarctic Peninsula in the Bellingshausen Sea in Antarctica have not been well mapped and studied. It’s not easy to get there, after all. Drs. Patricia Esquete from the University of Aveiro, Portugal, and Aleksandr Montelli from the University College London, UK, will travel to this remote region with an international team of scientists to create the first high-resolution maps of this region and study the animals that dwell here. 

Cruise: Canyons, Vents, and Seeps of the Chile Margin

On May 2, 2008, Chile’s Chaitén volcano erupted without warning, spewing ash 30 kilometers into the air.  This ash blanketed the landscape, and heavy rain in the following days triggered devastating volcanic mudflows that flowed down mountainsides and into the fjords below. The nearby town of Chaitén evacuated as the volcano completely transformed the surrounding landscape. While the destruction was easy to observe on land, scientists have not yet closely examined the impacts the eruption had on the surrounding ocean environments. Dr. Sebastian Watt of the University of Birmingham, UK, will lead an international team to study the underwater effects of the Chaitén eruption from the research vessel Falkor (too). Understanding the imprint of the Chaitén eruption in the marine environment will also help unlock deeper-time records of major volcanic eruptions in the region, allowing scientists to reconstruct volcanic behavior in Southern Chile over geologic time.

Cruise: High Seas and Seamounts of the Nazca Ridge

8 July - 9 August 2024 #NazcaHighSeas Lush forests of deep-sea corals and sponges host animals and organisms that defy imagination. Many endangered or threatened species like sea turtles, blue whales, and sharks travel here to feed on the abundant nutrients upwelling from the deep. The 8000-meter-deep Atacama Trench, the Southeast Pacific Oxygen Minimum Zone, … Continued

Cruise: Journey to the Nazca Ridge

Expedition dates: July 6 - Aug. 9, 2024 Numerous species, including seabirds, whales, and sea turtles,  likely utilize the nutrient-rich waters circulating through Peru’s Nazca Ridge National Reserve for sustenance. Still, little is known about what lives in this Ocean region. An unknown number of prominent seamounts with peaks ranging from 1870 to 1903  meters … Continued

Cruise: Living Fossils of the Atacama Trench

Expedition dates: May 24 - June 6, 2024 The Atacama in northern Chile is the oldest and driest desert on Earth. While tectonic activity reconfigured the shape and arrangement of land masses over the last 150 million years, the Atacama Desert remained essentially at the same latitude. And, offshore, where the desert meets the sea, … Continued

Cruise: Microbes in Oxygen Minimum Zones

Expedition dates: April 12 - May 15, 2024 Oxygen Minimum Zones, or OMZs, are areas in the water column with less oxygen, primarily due to naturally occurring physical and biological processes within the Ocean. The core of the OMZs is anoxic, making them inhospitable to most large animals, yet microbes have adapted to live and … Continued
