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...
GEOSTAR deep seafloor missions: magnetic data analysis and 1D geoelectric structure underneath the Southern Tyrrhenian Sea
GEOSTAR Tyrrhenian Sea deep seafloor electrical conductivity lithosphere
2015/8/28
From 2000 to 2005 two geophysical exploration missions were undertaken in the Tyrrhenian deep seafloor at depths between -2000 and -3000 m in the framework of the European-funded GEOSTAR Projects. The...
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...
Seafloor topography influences ocean circulation in two basic ways. First, it steers ocean flows. Second, it provides barriers that prevent deep waters from mixing, except within deep passageways that...
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...
Magnetic signature of large exhumed mantle domains of the Southwest Indian Ridge – results from a deep-tow geophysical survey over 0 to 11 Ma old seafloor
Magnetic signature large exhumed mantle domains the Southwest Indian Ridge deep-tow geophysical survey 0 to 11 Ma old seafloor
2015/1/6
We investigate the magnetic signature of ultramafic seafloor in the eastern part of the Southwest Indian Ridge (SWIR). There, detachment faulting, continuous over 11 Myr, exhumed large areas of mantle...
