Seafloor borehole array seismic system (SEABASS)
(Woods Hole Oceanographic Institution, 1993-01)
The Seafloor Borehole Array Seismic System (SEABASS) has been developed to measure the pressure and three dimensional particle velocity of the VLF sound field (2-50HZ) below the seafloor in the deep ocean (water depths ...
Bottom array specifications for the low frequency acoustic seismic experiment (LFASE)
(Woods Hole Oceanographic Institution, 1991-10)
The Low Frequency Acoustic Seismic Experiment (LFASE) was conducted to measure sound propagation and ambient noise above, at and below the sea floor. To this end an array consisting of four geophone nodes was introduced ...
AFRAME : a video animation capability for displaying FINDIF numerical model output
(Woods Hole Oceanographic Institution, 1995-07)
This report describes the development of a facility for recording time-varying computer graphics on video tape. The primary purpose of the facility is to produce animation sequences of ocean and seafloor acoustic wave ...
Progress report on the development of the seafloor borehole array seismic system (phase II) : July 14, 1992 to January 31, 1996
(Woods Hole Oceanographic Institution, 1996-06)
The Seafloor Borehole Array Seismic System (SEABASS) was originally developed to record autonomously on the seafloor the signals received on a four-sonde three-component borehole geophone array in the VLF band (2-50Hz)(Stephen ...
LFASE data transcription software CGG2ROSE2 version 1.1 : program report
(Woods Hole Oceanographic Institution, 1990-05)
Seismic data obtained using borehole seismometers during the LFASE experiment (Stephen et al, 1989; Koelsch et al, 1990) are retrieved from the seafloor instrument package and converted to a data format more suitable for ...
A sea floor winch system for wire line re-entry of deep sea boreholes
(Woods Hole Oceanographic Institution, 1990-12)
The following report describes the scientific motivations for the use of a Sea Floor Winch System for Wireline Re-entry of Deep Sea Boreholes and presents a conceptual design for the winch system.
LFASE data processing system overview
(Woods Hole Oceanographic Institution, 1990-06)
This technical report provides an overview of the LFASE data processing system. This software system is made up of over twenty-five programs which are used to acquire, reduce, and analyze acoustic seismic data collected during ...
Late Cenozoic geology of the Central Persian (Arabian) Gulf from industry well data and seismic profiles
(Woods Hole Oceanographic Institution, 1988-04)
Industry seismic reflection profiles shot in the 60's and early 70's in the central Persian (Arabian) Gulf are used to map two late Tertiary unconformities, and velocity data from a centrally located well is used to ...
Ambient noise analysis and finite difference modelling of VLF borehole seismic data
(Woods Hole Oceanographic Institution, 1987-03)
This report describes a preliminary analysis of borehole seismic data to determine VLF/Sub-bottom Seismic Noise in the Atlantic and the preliminary results of finite difference modelling for a Cape Fear environment. Noise ...
Tests of propellers for Alvin side propulsion units
(Woods Hole Oceanographic Institution, 1967-07)
Full scale dynamometer tests were run on a series of unshrouded propellers in the range of propeller diameters considered practical for use on the side propulsion units of the research submarine ALVIN. Measurements taken ...
