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 ...
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 ...
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 ...
Handbook of oceanographic engineering materials : volume I - metals and alloys
(Woods Hole Oceanographic Institution, 1972-12)
This handbook is intended to serve as an aid in materials selection to Oceanographic engineers and designers. As such it is intentionally limited to materials that may be used advantageously in the marine environment.
The marine disposal of sewage sludge and dredge spoil in the waters of the New York Bight
(Woods Hole Oceanographic Institution, 1971-01-29)
The dumping of sewer sludge and dredge spoil in the waters of the New York Bight and the effect of this waste disposal practice on the marine environment is reviewed. The. quantities and composition of these wastes is ...
A user’s manual for finite difference synthetic seismogram codes on the CYBER 205 and CRAY XMP-12
(Woods Hole Oceanographic Institution, 1986-11)
Over the past eight years, a software package has been developed to solve the elastic wave equation by the method of finite differences (Hunt et al., 1983; Stephen, 1983; Stephen, 1984a; Stephen, 1984b; Nicoletis, 1981). ...
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 ...
User's guide for FINDIF at SACLANTCEN
(Woods Hole Oceanographic Institution, 1992-05)
FINDIF solves the elastic wave equation for a line source in two dimensions by the finite difference method (Virieux,1986; Stephen,1988b). The solution is carried out in the time domain for either pulse or CW sources. ...
Bathymetry and sediment thickness survey of the Hawaii-2 cable : cruise report for Kiwi expedition leg 2 on the R/V Roger Revelle
(Woods Hole Oceanographic Institution, 1997)
The primary purpose of this cruise was to identify at least two potential observatory sites along the Hawaii-2 cable that would be suitable for drilling a hole to basement. There is a funded program, the Hawaii-2 Observatory ...
