Microbes seafloor survive byproducts radioactive process
2021/3/5
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...
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
2015/7/31
As the first cabled seafloor observatory that involves a geographically distributed network structure, the Victoria Experimental Network Under the Sea (VENUS) will oversee the deployment of three powe...
Dynamics of Seafloor Processes:Advances from Benthic Observing Technologies
Dynamics of Seafloor Processes Benthic Observing
2015/7/22
Interactions with the seafloor are a controlling characteristic of coastal environments, resulting in unique and intensified processes that define the coastal ecosystem (Figure 1). At the most fundame...
Forcing and Dynamics of Seafloor-Water Column Exchange on a Broad Continental Shelf
Forcing and Dynamics Seafloor-Water Column Exchange Broad Continental Shelf
2015/7/22
Relict sediments of elevated permeability characterize the majority of continental shelves globally (Emery, 1968). In these settings, interactions between benthic boundary layer (BBL) flows and seabed...
Monitoring the Seafloor Using the Noninvasive Eddy Correlation Technique:Integrated Benthic Exchange Dynamics
Noninvasive Eddy Integrated Benthi Exchange Dynamics
2015/7/22
The eddy correlation technique has been used for 60 years in atmospheric boundary layer research to measure land-air exchanges of different constituents (e.g., Swinbank, 1951). Only recently, the tech...
eohazards in the Western Ionian Sea: Insights from Non-Earthquake Signals Recorded by the NEMO-SN1 Seafloor Observatory
Western Ionian Sea Non-Earthquake Signals
2015/7/17
Seafloor instability resulting from both tectonics and volcanism affects the Western Ionian Sea. The NEutrino Mediterranean Observatory-Submarine Network 1 (NEMO-SN1), deployed 25 km offshore eastern ...
Measurements and Models of Heat Flux and Plumes from Hydrothermal Discharges Near the Deep Seafloor
Measurements and Models Heat Flux and Plumes Hydrothermal Discharges Deep Seafloor
2015/7/14
Deep-sea hydrothermal vents are conduits of heat and chemicals from the lithosphere to the hydrosphere. Their plumes rise hundreds of meters from the seafloor into the water column; during their ascen...
Seamount Discovery Tool Aids Navigation to Uncharted Seafloor Features
Seamount Tool Aids Navigation Uncharted Seafloor
2015/7/7
Wessel et al. (2010) highlight the need for a systematic mapping of seamounts in ocean basins. They estimate that 100,000 or 90% of the seamounts greater than 1-km tall are unobserved by either ship s...
A 'hydrothermal siphon' drives water circulation through the seafloor
hydrothermal siphon water circulation the seafloor
2015/7/13
Vast quantities of ocean water circulate through the seafloor, flowing through the volcanic rock of the upper oceanic crust. A new study by scientists at UC Santa Cruz, published June 26 in Natur...
Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that ...
