... modeling study. Laboratory acoustic emission tests were performed with North-Sea relevant rock samples to evaluate the micro-seismic applicability to offshore GCS monitoring. Acoustic and chemical sensor technologies are considered essential for marine monitoring of the seabed and water column...

In the onshore scenario, the pipe blowout causes CO 2 to enter the ambient air at 0.101325 MPa and 22.78 °C, whereas in the offshore scenario the blowout is into the water column at a depth of 50...

... Abstract In the deep waters of the Colombian Caribbean in situ measurements of current speed and direction in the water column are scarce. To address this gap, we conducted a 1-year metocean field campaign that included the deployment of three instrumented moorings at 1400 m, 2160 m and 3675 m...

Multibeam echo soundings from cruise AT21-02 were used to define a region with several ~600 to 900 m tall gas plumes in the water column directly above cratered hummocky regions of the sea...

.... By 1000 m they are almost undiscernible. On the shelf, the CTWs are characterized by phase speeds of about 0.5 m/s, periods of roughly 11 days and peak unfiltered velocities of 100 cm/s; far exceeding the energy from other processes except in the upper few meters of the water column. CTW velocity profiles...

Hydrothermal plumes produced by high temperature hydrothermal activity were located using chemical and physical anomalies in the water column. Using a CTD/rosette we collected water samples and measured physical...

In order to reduce the uncertainty of slick and seep correlations, sea current data at various depths throughout the water column would be needed at the time of SAR capture, and access to any seafloor cores would help ground truth interpreted seepage phenomena.

... structure represents a single seepage, all of them converging toward an impact point at the sea surface that can be associated to an emission point or vent in the seafloor. The rising speed of the oil in a water column of 1800 m is 10 cm/s, which corresponds to a lateral drift of about 1000 m. Active vents...

... Abstract A method is described for acoustical detection of bubble streams in the water column while conducting swath bathymetry surveys at 20 m altitude with a deep-diving ROV. Such bubble streams emanate from natural seafloor seeps. The same acoustical tools are then used to measure the flow...
