The Doldrums Fracture Zone
Our planet’s longest mountain range is located in the center of the Atlantic Ocean: the Mid-Atlantic Ridge. This submarine volcanic mountain chain stretches for more than 16,000 kilometers, shaping Earth’s geology where tectonic plates drift apart. As the plates separate, mantle material rises, partially melts, and generates magma that forms new oceanic crust. The movement of plates forms wrinkles and lines along the planet’s surface, known as fault zones, which tell the story of Earth’s tectonic history. These fault zones circulate water into the seafloor and through the crust, later releasing it with new chemical compositions— some of which feed deep-sea bacteria that fuel thriving ecosystems in the deepest, darkest parts of the Ocean. While chemosynthetic ecosystems are well documented along the ridge, little is known about what lives on the fault zones. The Doldrums Megatransform System is one of these fault zones formed where offset ridge segments are linked by transform faults as the Atlantic seafloor spreads apart. Here, tectonic plates scrape and slide past one another, creating fascinating geologic formations like fault scarps and sedimented basins, both of which can host areas of chemically altered seawater and deep-sea ecosystems. Dr. Aaron Micallef of MBARI (Monterey Bay Aquarium Research Institute) and the international team will travel to the Doldrums Fracture Zone to map and identify interesting geological features, and then use ROV SuBastian to visualize them. Key to their work will be The Childlike Empress AUV, which will both create high-resolution maps of the seafloor and use its sensors to sniff out interesting chemicals that indicate venting. This expedition marks the first time Schmidt Ocean Institute’s new AUV will be used for scientific research.

What are Seamounts and Guyots?

Back to Expedition

Greetings from the R/V Falkor in the northern Tasman Sea. My name is Alysha Johnson, and I am a PhD student from the University of Wollongong

There may not be volcanic islands, but there are seamounts and guyots below us, submerged below the water!

When volcanoes form on the seafloor, they build up over time as they erupt volcanic lava that cools to become basalt. If a volcano does not reach the surface of the ocean, it is called a seamount

We are currently mapping a deep basin and a north-south chain of guyots and seamounts in the Tasman Sea, called the Tasmantid Seamount chain. We have just completed mapping the Recorder Seamounts offshore Fraser Island. These volcanoes are part of a >2,400 km long chain of volcanoes

Many seamounts within this chain have flat tops, indicating that they must be guyots. However, as the Tasman Basin subsides, the guyots summits that previously were at the sea surface are now deeper than 400 m below the sea surface. Understanding these guyots' shapes (their geomorphology) may allow us to understand what processes affected these volcanoes in the past, and what modern volcanic islands may look like million years into the future.

Ecologically, these seamounts provide a hard substrate for marine organisms such as deep-sea corals and sponges to attach. The seamounts provide vital habitat for marine invertebrates like brittle stars and squat lobsters to live on and act as nurseries for deep-sea fish.

The seamounts also influence the flow of deeper waters, which results in the upwelling of nutrient-rich waters towards the sea surface. Upwelling increases the biological productivity of plankton and fish, which in turn provides food for sea birds, larger fish, whales, and dolphins. For our current voyage, we’re fortunate to have our expert seabird researchers to record daily observations of this marine life above and around the seamounts of the Tasman Sea.
