Foreword
By the National Science Foundation
The National Science Foundation is proud to play a leading role in partnership with the
U.S. Oceanographic community in the operation and management of the Ocean Drilling
Program (ODP). We are equally proud of the cooperation and commitment of our international partners, who contribute both financial and intellectual resources required to maintain the high quality of this unique program. The Ocean Drilling Program, like its
predecessor, the Deep Sea Drilling Project (DSDP), is a model for the organization and
planning of research to address global scientific problems that are of high priority internationally and of long-term interest to the scientific community and general public.
Major scientific themes guiding the development of specific drilling cruises range from
determining the causes and effects of oceanic and climatic variability to understanding the
circulation of fluids in the ocean crust and the resultant formation of mineral deposits.
Although such studies are at the forefront of basic scientific inquiry into the processes that
control and modify the global environment, they are equally important in providing the
background for assessing man's impact on the global environment or for projecting
resource availability for future generations.
The transition from the DSDP to the ODP was marked by a number of changes. The
471-foot JOIDES Resolution, which replaced the Glomar Challenger, has allowed larger
scientific parties and the participation of more graduate students, a larger laboratory and
technical capability, and operations in more hostile ocean regions. The JOIDES Resolution has drilled in all of the world's oceans, from the marginal ice regions of the Arctic to
within sight of the Antarctic continent. Over 1,200 scientists and students from 26 nations
have participated on project cruises. Cores recovered from the cruises and stored in ODP
repositories in the United States and Europe have provided samples to an additional 1,000
scientists for longer term post-cruise research investigations. The downhole geochemical
and geophysical logging program, unsurpassed in either academia or industry, is providing remarkable new data with which to study the Earth.
In 1994, NSF and our international partners renewed our commitment to the program
for its final phase. Of the 20 countries that supported ODP initially, only one, Russia, has
been unable to continue for financial reasons. As the reputation and scientific impact of
the program continue to grow internationally, we hope to add additional members and new
scientific constituencies. This global scientific participation continues to assure the program^ scientific excellence by focusing and integrating the combined scientific knowledge and capabilities of its member nations.
We wish the program smooth sailing and good drilling!

Foreword
By Joint Oceanographic Institutions, Inc.
This volume presents scientific and engineering results from the Ocean Drilling Program (ODP). The papers presented here address the scientific and technical goals of the
program, which include providing a global description of geological and geophysical
structures including passive and active margins and sediment history, and studying in
detail areas of major geophysical activity such as mid-ocean ridges and the associated
hydrothermal circulations.
The Ocean Drilling Program, an international activity, operates a specially equipped
deep-sea drilling ship, the JOIDES Resolution (Sedco/BP 471), which contains state-ofthe-art laboratories, equipment, and computers. The ship is 471 feet (144 meters) long, is
70 feet (21 meters) wide, and has a displacement of 18,600 short tons. Her derrick towers
211 feet (64 meters) above the waterline, and a computer-controlled dynamic-positioning
system stabilizes the ship over a specific location while drilling in water depths up to
27,000 feet (8230 meters). The drilling system collects cores from beneath the seafloor
with a derrick and drawworks that can handle 30,000 feet (9144 meters) of drill pipe.
More than 12,000 square feet (1115 square meters) of space distributed throughout the
ship is devoted to scientific laboratories and equipment. The ship sails with a scientific
and technical crew of 51 and a ship's crew (including the drill crew) of 62. The size and
ice-strengthening of the ship allow drilling in high seas and ice-infested areas as well as
permit a large group of multidisciplinary scientists to interact as part of the scientific
party.
Logging, or measurements in the drilled holes, is an important part of the program.
ODP provides a full suite of geochemical and geophysical measurements for every hole
deeper than 1300 feet (400 meters). For each such hole, there are lowerings of basic
oil-industry tools: nuclear, sonic, and electrical. In addition, a Formation MicroScanner is
available for high-resolution imaging the wall of the hole, a 12-channel logging tool provides accurate velocity and elastic property measurements as well as sonic waveforms for
spectral analysis of energy propagation near the wall of the hole, and a vertical seismic
profiler can record reflectors from below the total depth of the hole.
The management of the Ocean Drilling Program involves a partnership of scientists
and governments. International oversight and coordination are provided by the ODP
Council, a governmental consultative body of the partner countries, which is chaired by a
representative from the United States National Science Foundation (NSF). The ODP
Council periodically reviews the general progress of the program and discusses financial
plans and other management issues. Overall scientific and management guidance is provided to the operators of the program by representatives from the group of institutions
involved in the program, called the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES).
The Executive Committee (EXCOM), made up of the administrative heads of the
JOIDES institutions, provides general oversight for ODP. The Planning Committee
(PCOM), with its advisory structure, is made up of working scientists and provides scientific advice and detailed planning. PCOM has a network of panels and working groups that
screen drilling proposals, evaluate instrumentation and measurement techniques, and
assess geophysical-survey data and other safety and siting information. PCOM uses the
recommendations of the panels and committees to select drilling targets, to specify the
location and major scientific objectives of each two-month drilling segment or leg, and to
provide the science operator with nominations for co-chief scientists.
Joint Oceanographic Institutions, Inc. (JOI), a nonprofit consortium of U.S. Oceanographic institutions, serves as the National Science Foundation^ prime contractor for
ODP. JOI is responsible for seeing that the scientific objectives, plans, and recommendations of the JOIDES committees are translated into scientific operations consistent with
scientific advice and budgetary constraints. JOI subcontracts the operations of the program to two universities: Texas A&M University and Lamont-Doherty Earth Observatory
of Columbia University. JOI is also responsible for managing the U.S. contribution to
ODP under a separate cooperative agreement with NSF.
Texas A&M University (TAMU) serves as science operator for ODP. In this capacity,
TAMU is responsible for planning the specific ship operations, actual drilling schedules,
and final scientific rosters, which are developed in close cooperation with PCOM and the
relevant panels. The science operator also ensures that adequate scientific analyses are
performed on the cores by maintaining the shipboard scientific laboratories and computers
and by providing logistical and technical support for shipboard scientific teams. Onshore,
TAMU manages scientific activities after each leg, is curator for the cores, distributes
samples, and coordinates the editing and publication of scientific results.
Lamont-Doherty Earth Observatory (LDEO) of Columbia University is responsible for
the program's logging operation, including processing the data and providing assistance to
scientists for data analysis. The ODP Data Bank, a repository for geophysical data, is also
managed by LDEO.
Core samples from ODP and the previous Deep Sea Drilling Project are stored for
future investigation at four sites: ODP Pacific and Indian Ocean cores at TAMU, DSDP
Pacific and Indian Ocean cores at the Scripps Institution of Oceanography, ODP and
DSDP Atlantic and Antarctic cores through Leg 150 at LDEO, and ODP Atlantic and Antarctic cores since Leg 151 at the University of Bremen, Federal Republic of Germany.
Scientific achievements of ODP include new information on early seafloor spreading
and how continents separate and the margins evolve. The oldest Pacific crust has been
drilled and sampled. We have new insights into glacial cycles and the fluctuations of
ocean currents throughout geological time. ODP has also provided valuable data that shed
light on fluid pathways through the lithosphere, global climate change both in the Arctic
and near the equator, past sea-level change, seafloor mineralization, the complex tectonic
evolution of oceanic crust, and the evolution of passive continental margins.
Many of the scientific goals can be met only with new technology; thus, the program
has focused on engineering as well as science. To date, ODP engineers have demonstrated
the capability to drill on bare rock at mid-ocean-ridge sites and have developed techniques
for drilling in high-temperature and corrosive regions typical of hydrothermal vent areas.
A new diamond coring system promises better core recovery in difficult areas. In a close
collaborative effort between ODP engineers and scientists, a system has been developed
that seals selected boreholes ("CORKs") and monitors downhole temperature, pressure,
and fluid composition for up to three years. When possible, ODP is also taking advantage
of industrial techniques, such as logging while drilling, to obtain continuous downhole
information in difficult-to-drill formations.
JOI is pleased to have been able to play a facilitating role in the Ocean Drilling Program and its cooperative activities, and we are looking forward to many new, exciting
results in the future.

CD-ROM MATERIALS
There are two CD-ROMs in the back of this volume.
CD-ROM 1 contains depth-shifted and processed logging data provided by the Borehole Research Group at
the Lamont-Doherty Earth Observatory. CD-ROM 1
also contains shipboard gamma-ray attenuation porosity
evaluation (GRAPE), index property, magnetic susceptibility, and natural gamma data of cores collected on
board the JOIDES Resolution during Leg 160. This CDROM was produced by the Borehole Research Group at
the Lamont-Doherty Earth Observatory, the wireline
logging operator for ODP. CD-ROM 2 contains
scanned structure VCDs for Sites 963, 965, 968, and
973; thin-section descriptions for Sites 966, 967, 970,
and 971; and selected tables from Chapters 4-14 and 19
(see list below).

The above structure is identical in each site and/or hole.
The INDEX file contains a summary of all the files
loaded on the CD-ROM. The software documentation
file in the GEN_INFO directory contains information
on which software packages work best to import portable bit map (PBM-8 bit binary) raster files. It also
includes network sources for the graphics software and
data compression information. The README file gives
information on whom to contact with any questions
about the production of or data on the CD-ROM.
All of the ASCII files (with the exception of the SWF
files) are TAB delimited for compatibility with most
spreadsheet and database programs. Holes that have
more than one logging pass with the same tools are
labeled Main and Repeat for conventional logs, or Pass
1, Pass 2, etc. for FMS. If the files are not in separate
directories, they may just be annotated with "m" and "r"
or " 1 " and "2" in the data file names when there is room
for only one character. Holes that have long logging
runs are often divided into TOP and BOTTOM directories. The files may just be annotated with "top" or "bot"
in the data file names where space permits or a "t" or
"b" when there is room for only one character. Check
the documentation file for a given directory for further
clarification.
In the FMS-PBM format directory there are two subdirectories, 1:1 ratio with maximum 10-m-long image
raster files and 1:10 ratio with maximum 100-m-long
image raster files. The image raster files are named
according to their depth interval. The raster documentation files contain image file parameter information necessary for use with most graphic software packages.

ACKNOWLEDGMENTS
The Ocean Drilling Program Leg 160 scientific party expresses its thanks and appreciation to all those who gave invaluable help
to make the outcome of drilling in the eastern Mediterranean Sea an outstanding success.
We are indebted to Captain Tom Ribbens, his officers, and the crew of the JOIDES Resolution (Sedco/BP 471), as well as Operations Manager Gene Pollard and the drilling crew. These efforts ensured that our scientific goals were translated into drilling
reality. We also greatly appreciate the efficient and dedicated support provided by the ODP marine technicians.
Our work built on the earlier efforts of the proponents of the Mediterranean Sapropels and Mediterranean Ridges proposals.
Thanks go especially to Angelo Camerlenghi for his help during the planning of the leg. We thank the JOIDES Planning Structure,
especially the Sedimentary and Geochemical Processes Panel, Tectonics Panel, and Planning Committee for their support of Leg
160. Finally, we acknowledge the governments of Italy, Greece, and Cyprus for facilitating our operations.
