Workshop Announcement ODSN



Bremen, 28.9.95

Dear Colleagues,

following You find the announcement for an international workshop to be
held in Bremen at the end of the year, which invites scientists from different
to discuss the establishment of a widely based stratigraphic communication
and data exchange network.

Everybody is invited to participate, contribute his ideas and needs and
join this effort to improve the quality, accessibility and usage of
stratigraphic data and to allow the integration of data sets.

Announcement for an International Workshop:

"Objectives and Implementation of an 
Ocean Drilling Stratigraphic Network (ODSN)"

Bremen, Germany, December, 18 - 20, 1995

Sediment stratigraphic data from deep ocean drilling have been successfully 
collected for several decades within the Deep Sea Drilling Project and Ocean 
Drilling Program. These international activities had a major impact on the 
understanding of the Earth's climate system and its history and provided 
detailed information about environmental conditions in the geologic past. 
New techniques and data sets, their increasing amount, quality and 
resolution require new approaches to produce integrated chronostratigraphic 
models from different data sources. Where the acquisition of data related to 
shipboard drilling activities is organized in a professional manner through 
the drilling program operator, the results of subsequent shorebased 
activities falls under the responsibility of the individual scientists. 
Part of the data are published in the scientific results volumes, but the 
paper medium is no longer providing an adequate archive for these scientific 
efforts. Part of the data is available in electronic form in the ODP 
database and on DSDP and ODP CDROMs, but in a variety of formats that are 
not readily integrated.
An "Ocean Drilling Stratigraphic Network" should be established to overcome 
some of these deficits and provide a distributed database system and a 
communication network for data exchange and scientific cooperation. It 
should promote development and repeated calibration of integrated 
stratigraphies for drill sites, regions or geologic time intervals on a 
long-term basis. The project is viewed as a resource for further scientific 
programmes to provide improved age models, better time correlation between 
drill sites, regions and oceans and to finally maintain a homogenous 
stratigraphic data set.
As a starting initiative a group of marine geologists and geophysicists from 
four North German institutions (AWI, GeoB, GEOMAR, GPI) is organizing a 
workshop about the perspectives for the described approach. It is planned to 
exchange experiences from other projects, to discuss the technical, 
scientific and logistic aspects of these ideas with colleagues in particular 
from the ODP community and to develop a final concept for an "Ocean Drilling 
Stratigraphic Network". The resulting document may also contain letters of 
intent from interested institutions and individuals for a long-term 
commitment to the project, can serve as a base for further scientific 
project proposals. The main objectives of the project and the workshop are:
· Design of a network for information and data exchange between scientists 
related to ocean drilling activities (in particular ODP and DSDP)
· Design and buildup of a database, which includes drilling-related data 
sets and stratigraphic results and interpretations produced after the 
shipboard activities. A close connection to the JANUS database project for 
shipboard data acquisition is essential. The database will be repeatedly 
updated from new calibration results and chronostratigraphic concepts to 
maintain age data on a high quality level. 
· Collection and evaluation of biostratigraphic and taxonomic microfossil data
· Development of uniform micropaleontologic taxonomic concepts to provide 
the essential basis for comparisons between data set in space and time
· Establishment of integrated, easily updatable chronostratigraphic concepts 
and age models for DSDP and ODP drill sites, using and combining all 
available stratigraphic data sets
· Availability of the database in the Internet and WordWideWeb
· Preparation of stratigraphic data syntheses for future drilling campaigns
· Initiation of complex scientific projects, which are based on coherent 
data sets and permit regional analysis (e.g. paleobiogeographic) and in 
terms of well defined time slices
