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 ...
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 ...
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 ...
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 ...
Cruise plans for R/V Chain cruise #43 : Indian Ocean expedition
(Woods Hole Oceanographic Institution, 1964-01)
The proposed cruise of R/V CHAIN to the Indian Ocean will take place from February to June 1964. Following the Indian Ocean section of the cruise, R/V CHAIN will proceed to the Mediterranean Sea and will do further work ...
Twenty-four (24) man-hour test of Alvin's environmental system
(Woods Hole Oceanographic Institution, 1964-11)
ALVIN's specifications call for a 48 man-hour environmental system capability. To check this, a 24 man-hour test was run as follows: Two successive test periods of six (6) hours each with a two (2) man crew inside the ...
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 ...
