Seeing Sur Ridge: Transforming deep-sea mapping data to reveal the majesty of an underwater oasis
WARNING: This video may potentially trigger photosensitivity reactions. Viewer discretion is advised.
In 2013, after many years spent mapping Monterey Bay and its environs, MBARI and NOAA scientists discovered an underwater oasis—lush with corals and sponges—just 35 kilometers (22 miles) west of Big Sur. This rocky ridge, called Sur Ridge, stands over 500 meters (1640 feet) tall and stretches over 20 kilometers (12 miles) long—roughly the size of Manhattan. MBARI has been working diligently to create ever more detailed maps of Sur Ridge for more than twenty years to better understand its geologic processes—like underwater landslides—and to monitor the health of the marine life that calls it home—including the impacts of climate change.
Data collected by MBARI’s mapping team has helped b...

Deep-sea surveys of proposed wind-farm site off the California coast
A fleet of floating wind turbines anchored in deep water off the California coast could boost the state’s production of clean energy. But for that vision to become reality, the seafloor in the area of the proposed wind farm must be stable enough for the turbine anchors and the cables that will carry the energy to shore. With his long career of studying the seafloor—including the specific location of this proposed wind farm—MBARI Geologist Charlie Paull is the perfect person to lead the study of the wind-farm seafloor site.
MBARI conducted eight high-resolution autonomous underwater vehicle (AUV) mapping surveys of the region in April 2018 to help establish how rapidly seafloor features form and identify the seafloor footprint of existing buried submarine cables. These surveys were follow...

Automating a 20-year survey of deep-sea animals
A new robot that surveys the deep sea, collecting data autonomously, is providing a boost to one of MBARI’s longest running research projects. The Midwater Time-Series Project consists of video surveys of animals in the upper kilometer of the water column in Monterey Bay. Trained biologists review the video footage, identifying and documenting every animal seen. The resulting data can be analyzed to determine what species live in the midwater region, adding to our understanding of life in the deep sea, and how it is changing over time. The new i2MAP (Investigations of Imaging for Midwater Autonomous Platforms) AUV system will increase survey efficiency and add to the remotely operated vehicle observations MBARI researchers have been making over the past two decades.

NOAA 'Omics Seminar Series: eDNA-Dominant Marine Fish Species Characterize Coastal Habitats
Date: February 28, 2024
Title: eDNA-Dominant Marine Fish Species Characterize Coastal Habitats: an eDNA-Based Classifier Approach to Aid Marine Biogeography and Ocean Monitoring
Presenter: Mark Stoeckle & Jesse Ausubel
Abstract: A small minority of species typically account for the great majority of individuals or biomass. Here we characterize marine coastal habitats based on abundance of marine fish environmental DNA. We designate the ten most eDNA-abundant fish species in each habitat as eDNA-dominant species. eDNA-dominant species are similar within but differ among habitats and seasons and accord with abundance by traditional survey methods. “Classifiers” based on eDNA-dominant fish species could help map marine fish habitats and monitor changing oceans. Advantages include rel...

“Most of the seafloor that has been mapped thoroughly is close to shore. Thanks to all of the hydrographers that constantly survey the world’s coastlines, we now have nautical charts (specialized maps) that are used to safely navigate ships. Coastal areas are well surveyed and often re-surveyed because seafloor conditions continuously change, especially close to shore. Hydrographers make sure that ships have the information they need to navigate safely by detecting and reporting new hazards to navigation with each chart update.”

This animation combines data from ship-based multibeam sonar at 25 meters (82 feet) in resolution, autonomous underwater vehicle (AUV) multibeam mapping data at one meter (about three feet) in resolution, and remotely operated vehicle (ROV) mapping lidar data at five centimeters (two inches) in resolution. MBARI scientists worked with Los Angeles film production company Frame 48 to visualize the terrain of Sur Ridge in astonishing detail. These amazing images demonstrate what’s possible when scientists and engineers work together to develop new technology for exploring the deep ocean.

A fleet of floating wind turbines anchored in deep water off the California coast could boost the state’s production of clean energy. But for that vision to become reality, the seafloor in the area of the proposed wind farm must be stable enough for the turbine anchors and the cables that will carry the energy to shore. With his long career of studying the seafloor—including the specific location of this proposed wind farm—MBARI Geologist Charlie Paull is the perfect person to lead the study of the wind-farm seafloor site.
MBARI conducted eight high-resolution autonomous underwater vehicle (AUV) mapping surveys of the region in April 2018 to help establish how rapidly seafloor features form and identify the seafloor footprint of existing buried submarine cables. These surveys were followed up with remotely operated vehicle dives to further study the site and to collect sediment cores to learn more about the processes that shape the seafloor and affect its stability.
MBARI is proud to be able to contribute its marine operations and science expertise to this effort to address societal needs, and is able to do so through its steady commitment to technology development and improved understanding of basic ocean processes.

Deep beneath the ocean’s surface lie vast areas of seabed that have never before been explored by humankind. Now state-of-the-art technology is giving these scientists an unprecedented opportunity to conduct research that is vital to protecting the ocean. And to uncovering the true nature of damage being done to it.
This is the RV Investigator. The ship used by the Australian government and marine scientists to research the deep ocean.
Off the coast of Tasmania a team of scientists is on a remarkable mission to investigate marine life thousands of metres below the surface. To do this they are using advanced cameras attached to a submersible platform. The system is carefully dropped 1,000 metres down below the surface. It’s Karl’s job to make sure he stops the platform just two metres before it reaches the seabed.
Then the challenging task begins - navigating the craggy and uneven terrain of seamounts. Though found throughout the ocean,
from the poles to the equator, over 99% of them are unexplored. Scientists have discovered that seamounts support astonishingly diverse and unique ecosystems and provide food and spawning grounds to a wide variety of fish and sea mammals.
Today the team is surveying an area of the ocean floor that has never been explored before. In these dark depths over 1,000 metres below the surface the team is astonished to discover thriving coral communities. But the team is also visiting parts of the seabed that have experienced human contact before. To survey areas that have been damaged by bottom trawling. This method of fishing provides the biggest annual catch globally but uses vast nets that can literally scrape marine life off the ocean floor. Damage to seamounts here was first logged by scientists in the 1990s. But a marine protected area now keeps many of them safe from the nets.
The first signs are encouraging. Marine life is returning, anemones are beginning to grow back on the damaged areas. But it’s what the team can’t see that’s more worrying. There is little evidence that damaged coral itself the heartbeat of ecosystems down here
is reforming.
The data gathered here will form part of a growing body of evidence helping scientists evaluate whether damaged areas
will ever properly recover. The results from this trip are vital for the ocean’s would-be protectors as part of the wider battle to preserve marine habitats across the ocean floor. And make the case for more controlled and sustainable fishing.

To do this they are using advanced cameras attached to a submersible platform. The system is carefully dropped 1,000 metres down below the surface. It’s Karl’s job to make sure he stops the platform just two metres before it reaches the seabed.
Then the challenging task begins - navigating the craggy and uneven terrain of seamounts. Though found throughout the ocean,
from the poles to the equator, over 99% of them are unexplored. Scientists have discovered that seamounts support astonishingly diverse and unique ecosystems and provide food and spawning grounds to a wide variety of fish and sea mammals.
Today the team is surveying an area of the ocean floor that has never been explored before. In these dark depths over 1,000 metres below the surface the team is astonished to discover thriving coral communities. But the team is also visiting parts of the seabed that have experienced human contact before. To survey areas that have been damaged by bottom trawling. This method of fishing provides the biggest annual catch globally but uses vast nets that can literally scrape marine life off the ocean floor. Damage to seamounts here was first logged by scientists in the 1990s. But a marine protected area now keeps many of them safe from the nets.
The first signs are encouraging. Marine life is returning, anemones are beginning to grow back on the damaged areas. But it’s what the team can’t see that’s more worrying. There is little evidence that damaged coral itself the heartbeat of ecosystems down here
is reforming.
The data gathered here will form part of a growing body of evidence helping scientists evaluate whether damaged areas
will ever properly recover. The results from this trip are vital for the ocean’s would-be protectors as part of the wider battle to preserve marine habitats across the ocean floor. And make the case for more controlled and sustainable fishing.

Title: eDNA-Dominant Marine Fish Species Characterize Coastal Habitats: an eDNA-Based Classifier Approach to Aid Marine Biogeography and Ocean Monitoring
Presenter: Mark Stoeckle & Jesse Ausubel
Abstract: A small minority of species typically account for the great majority of individuals or biomass. Here we characterize marine coastal habitats based on abundance of marine fish environmental DNA. We designate the ten most eDNA-abundant fish species in each habitat as eDNA-dominant species. eDNA-dominant species are similar within but differ among habitats and seasons and accord with abundance by traditional survey methods. “Classifiers” based on eDNA-dominant fish species could help map marine fish habitats and monitor changing oceans. Advantages include relatively low sampling requirements, a single technology applicable to diverse habitats, and ease of application to multiple datasets.

Nekton Mission I - XL Catlin Deep Ocean Survey - is a major scientific marine research expedition to investigate ocean function, health, and resilience across the Northwest Atlantic and focused on Bermuda.
Over 80 scientists participated from 12 marine research institutes to discover dozens of new species in Bermudian mesophotic and rariphotic depths (30m-300m) ranging from small cryptofauna to wide spread coverage of a new black coral species standing up to 2m high. The team documented the deepest recorded evidence of Lionfish globally – revealing the spread of this invasive species deeper into the ocean than previously known. A total of 20 scientific peer-reviewed papers are being published, all data is open-sourced and all specimens are retained in Bermuda and curated in the Bermuda Aquarium, Museum & Zoo.
The Mission received global attention promoting and captivating an audience of 750million with the wonders of Bermuda and the previously undiscovered deep ocean. Media coverage included from the BBC, PBS, Forbes, Telegraph, New Scientist, Guardian, Sky News, Geographical. With Sirius XM, the Mission carried out the deepest live radio show in history. The Mission also launched a new educational programme - Submarine STEM with new resources and dynamic 360 VR films all distributed freely across Bermuda and reaching 1million young people globally.
Capacity Development has been a core objective of the Mission and Bermudians have been at the heart of the Mission across scientific research and publications, global media and education engagement.
Nekton would like to thank our partners from the Bermuda Government Department of the Environment & Natural Resources, Department of Education, Bermuda Aquarium, Museum & Zoo, Bermuda Institute of Ocean Sciences (BIOS), Bermuda Tourism Board, Bermuda Underwater Exploration Institute (BUEI), CITV (Bermuda National Broadcaster), Bermuda Royal Gazette along with schools across country.
