the overall consistency of approach by all the
authors; a difficult task given the number involved
and the ranges of data from which they would be
working. To help with this, a number of workshops
were held for the authors, the most notable of
which was a 3-day residential meeting at the
wonderful field- centre premises of Chris
Cornford's Integrated Geochemical Investigations
at Bideford in Devon.

STRATAGEM Atlas of the Neogene of the
glaciated European margin

STRATAGEM is a 3-year project supported by the
European Commission as part of their 5th
Framework Programme; it started on 1st March
2000 and is therefore approaching completion.
The project has two main deliverables: a
stratigraphic atlas and a margin evolution model.
The first of these two objectives has been
accomplished with the production of an atlas
entitled 'The Neogene stratigraphy of the
glaciated European margin from Lofoten to
Porcupine' (STRATAGEM Partners, 2002).
STRATAGEM has been taking a very regional
approach to the stratigraphical development of the
European glaciated margin, studying a large area
extending over 18 degrees of latitude from the
Porcupine Basin in the south to the Lofoten
Islands in the north.
Most of the study area was influenced by
Pleistocene ice sheets that extended to the shelf
break at their maxima, although the southern
portion of the study area remained ice free.
Therefore the study area spans a range of
Pleistocene environments, and includes the
southernmost point at which ice sheets will have
extended as far as the shelf break.
A particularly significant aspect of Plio-
Pleistocene sedimentation has been the
development of large prograding wedges along
the margin (see the project logo). Much of this
development is due to downslope processes, but
an important aspect that is emerging from the
project is the significant contribution of alongslope
sediment transport to the sedimentary budget on
the margin.
The area is also critical for the study of the
development of oceanic currents during the later
Cenozoic as the gateway through the Faeroe-
Shetland Channel and the Rockall Trough
evolved. The pattern of oceanic currents is
reflected in the architecture of the Neogene
sediments, which commonly show indications of
emplacement under the influence of contour
currents.
The STRATAGEM stratigraphic atlas places the
Neogene sediments in a 'megasequence'
framework that can be consistently applied along
the margin. The main characteristics of these units
are defined and described, with seismic data
examples, distribution maps, and a compilation of
core and sample data from the region.
Additionally, there is a section on higher resolution
stratigraphy that provides more-detailed
information on some of the younger units at a
range of scales.
During the remaining time of the project, an
integrated margin evolution model will be
produced; this will provide a context within which
other margin studies can be viewed. The final
report will include post-rift backstripping modelling
that has been carried out on selected transects
along the margin. Another section will make
comparisons with other glaciated margins, such
as Greenland and Antarctica, thus placing our
study in a global perspective.
STRATAGEM is a fine example of
IndustryAcademia co-operation, for there are
close links with the hydrocarbon industry,
principally through four Joint Industry Projects
active on the north-west European margin, and
who are providing data for the project: the Seabed
Project in Norway, the GEM/FOÍB Network in the
Faroes, the WFA (Western Frontiers Association)
in the UK and PIPCoRSG (the Petroleum
Infrastructure Project's Rockall Studies Group) in
Ireland. The WFA have sponsored the distribution
of 50 CD-ROMs of the STRATAGEM stratigraphic
atlas to academic institutions.
For others wishing to obtain copies of the atlas,
details of availability, as well as further information
about the project, can be obtained from the
