Radiolaria 14 Symposia
TX, 77845. You will receive an application form to fill
out and return to ODP.
ODP Sets 1995 Drilling
ODP is currently staffing Legs 159 onwards.
Shipboard participation is by invitation from ODP's
science operator at Texas A&M University. Information
and applications can be obtained by contacting the Ocean
Drilling Program. Texas A&M Univesity, 1000

Leg 159 Return to Site 735
The purpose of this leg is to return to ODP site 735
on the southwest Indian Ridge, and deepen hole 735B to a
nominal depth of 2 ~m mbsf. The principle objective of
this proposed leg is to understand the nature of the
processes involved in the generation of the lower crust,
and the put some constraints on the lower crustal
stratigraphy at the slowest end of the spreading spectrum.
Leg 160 Eastern Eq. Atlantic Transform
The key issues to be addressed by drilling include an
evaluation of the tectonic and sedimentary processes
involved in the creation of the main morpho-structural
features ~enerated at the Cate d'Ivoire-Ghana Transform
Margin. Results should provide data on the timing, rate
and de~ree of vertical motion (subsidence and uplift) of the
Cote d"Ivoire-Ghana Transform Margin.
Leg 161/162 Mediterranean I & II
The proposed two lef!s of drilling in the
Mediterranean will address three main objectives: the
- 13 -
Alboran Basin (Western Mediterranean), drilling on the
Mediterranean Accretionary Complex (Eastern
Mediterranean), and an E-W transect across the
Mediterranean Sea to sample and study organic-rich layers
called Sapropels.
Leg 163 N. Atlantic Arctic Gateways
This is the second of two North Atlantic-Arctic
Gateways (NAAG) legs. The first leg, ODP Leg 151 was
drilled August - September of 1993. The scheduled second
le~ of NAAG drilling will focus on the same goals as
NAAG I but will also collect cores to try and resolve
millermial scale climate variability and provide links to
ice core data.
Leg 164 Gas Hydrates
Gas hydrates are a solid phase composed of water and
low molecular weight gases (~redominantly methane)
which form under conditions of low temperature, high
pressure, and gas saturation; conditions that are common
in the upper few hundred meters of rapidly accumulating
marine sediments. The main o6jechves of the proposed
leg are to investigate the in situ characteristics of gas
hydrates.
Leg 165 Test of the DCS
Throughout the past six years the Ocean Drilling
Program has expended considerable effort on the design
and development of a Diamond Coring System (DCS).
The Planning Committee has tentatively scheduled an
engineering leg during which the prime objective will be
a test of the diamond coring system and in particular the
secondary heave compensation system.
Report of "Radiolarian events" Symposium
International Geological Congress, Kyoto, Japan August, 1992
Symposium "Radiolarian events" of IGC (29th
International Geological Congress) held on August 24-25
convened by Drs. Patrick DE WEVER (Univ. Pierre et
Marie-Curie, France), WANG Naiwen (Chinese Acad.
Geol Sci., China) and Akira YAO (Osaka City Univ.,
Japan) in the Kyoto International Conference Hall.
Twenty-two abstracts were submitted covering
biostratigraphy, paleobiogeography and paleoecology of
Phanerozoic radiolarians. (Two presentations were
canceled.) The following was the program of symposium
