Some seafloor microbes can take the heat: And here's what they eat
microbial deep-sea carbon cycle methane organic compound
2021/8/5
In two new studies on life in the seafloor of the Guaymas Basin, in the Gulf of California, scientists show that distinct regions within the Basin harbor specially adapted microorganisms; discover new...
Microbes deep beneath seafloor survive on byproducts of radioactive process（图）
Microbes seafloor survive byproducts radioactive process

Microbes in sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules, report U.S. National Science Foundation-funded researchers at t...
Microbial diversity below the seafloor is as rich as on Earth's surface（图）
Microbial seafloor rich Earth's surface
2020/10/30
For the first time, researchers have mapped the biological diversity in marine sediment, one of Earth's largest global biomes. Although marine sediment covers 70% of Earth's surface, little was known ...
Microbes far beneath the seafloor rely on carbon recycling to survive（图）
Microbes far beneath seafloor rely carbon recycling survive
2020/3/20
Scientists at the Woods Hole Oceanographic Institution have revealed how microorganisms survive in rocks nestled thousands of feet beneath the ocean floor in the lower oceanic crust. The study is publ...
Robotic underwater vehicle snaps first images of seafloor beneath Antarctica's Thwaites Glacier（图）
Robotic underwater vehicle snaps first images seafloor beneath Antarctica Thwaites Glacier
2020/2/20
During the first study of the ocean floor beneath Antarctica’s Thwaites Glacier, scientists took images of the glacier's foundations. Thwaites now accounts for about 4% of global sea level rise, and r...
Underwater volcano's fiery eruption captured in detail by seafloor observatory
Underwater volcano fiery eruption captured seafloor observatory
2016/12/27
A sensor array off the Pacific Northwest coast has captured the cracking, bulging and shaking from the eruption of Axial Seamount, a nearly mile-high undersea volcano, in more detail than ever before....
Indication of hydrothermal deposits and ore area on caldera floor and shallow sub-seafloor of the Bayonnaise knoll, based on high-resolution acoustic investigation
hydrothermal deposits high-resolution acoustic observation AUV sub-seafloor SBP
2017/4/10
The Bayonnaise knoll, an active submarine volcano belonging to an actively rifted part of the Izu-Bonin volcanic arc,
exhibits hydrothermal ore deposits on its caldera floor in a region known as the ...
Deep seafloor magnetic observations under GEOSTAR project
GEOSTAR project Tyrrhenian sea Magnetic observation
2015/9/7
Performing good quality magnetic observations is not an easy task; making them in the extreme marine environment is even much more challenging. The European funded GEOSTAR project succeeded in reachin...
A fleet of multiparameter observatories for geophysical and environmental monitoring at seafloor
long-term multidisciplinary seafloor observatories geophysical and environmental seabed monitoring
2015/9/7
Seafloor long-term, multiparameter, single-frame observatories have been developed within the framework of European Commission and Italian projects since 1995. A fleet of five seafloor observatories, ...
Seafloor Observatory Science: a Review
multidisciplinary seafloor observatories marine science and technology
2015/9/7
The ocean exerts a pervasive influence on Earths environment. It is therefore important that we learn how this system operates (NRC, 1998b; 1999). For example, the ocean is an important regulator of c...
Computed Tomography of Macrostructure and Physical Property Variability of Seafloor Sediments
Macrostructure Physical Property Variability
2015/8/14
Models designed to simulate physical or mechanical phenomena associated with the seafloor often require a knowledge of or at least an ability to estimate, the physical property structure of the upper ...
Research Plans for a Mid-Depth Cabled Seafloor Observatory in Western Canada
Mid-Depth Cabled Seafloor Observatory Western Canada
