Commercial fishing vessels, automatic acoustic logging systems and 3D data visualization
Over the past five years we have investigated and used commercial fishing vessels and their associated acoustic hardware as platforms for acoustic surveying and data collection. During this period we developed an automated acoustic logging system that will simultaneously record data from the ship’s existing sounder, sonar, and navigation systems. The system was designed to be self contained and...
متن کاملFinal Report Deployment of an acoustic data logger on commercial fishing vessels to evaluate the potential of fishing-induced declines in local pollock abundance

متن کاملNumerical Simulation of 3D Acoustic Logging
A Finite-difference method for simulation of sonic waves propagating in a vicinity of a borehole filled with fluid and surrounded by a 3D heterogeneous elastic medium is developed. The method utilizes an explicit second order of approximation FD scheme on staggered grids that approximates the elastodynamic system of equations in cylindrical coordinates. A computational domain is surrounded by a...
متن کاملFatal falls overboard on commercial fishing vessels in Alaska.
BACKGROUND Falls overboard are a major contributor to commercial fishing fatalities in Alaska. The National Institute for Occupational Safety and Health has repeatedly identified falls overboard as a critical issue in commercial fishing safety. This article describes the problem of falls overboard and discusses possible ways to reduce the risk factors. METHODS Data from the Alaska Occupationa...
متن کاملAcoustic Waveform Logging
Full-waveform acoustic logging has made significant advances in both theory and applic cation in recent years, and these advances have greatly increased the capability of log analysts to measure the physical properties of formations. Advances in theory provide the analytical tools required to understand the properties of measured seismic waves, and to relate those properties to such quantities ...
