Archaean-Palaeoproterozoic Transition Emerging
Modern Aerobic Earth System
Scientific goals are (i) to establish a well
characterized, well dated, well archived section
for the period 2500-2000 Ma (ii) to document
the changes in the biosphere and the geosphere
associated with the rise in atmospheric oxygen
and (iii) to develop a self consistent model to
explain the genesis and timing of the
establishment of the modern aerobic Earth System.

International Continental Scientific Drilling
Program Potrok Aike Lake Sediment
Archive Drilling Project (PASADO)
An international research group is applying for
the research initiative Potrok Aike Lake
Sediment Archive Drilling Project (PASADO)
within the framework of ICDP. The intended
project will address several key issues related
to the evolution of maar craters, to quantitative
climatic and environmental reconstruction, fire
history, tephra and dust deposition and
palaeosecular variation of the Earth's magnetic
field for the last several glacial to
interglacial cycles. Moreover, dust and tephra
records will provide links to marine sediment
archives and ice cores. Obtained reconstructions
of climate variability will be compared to
climate simulations from GCMs to detect signals
of climatic forcing. Laguna Potrok Aike is
located at 52S within a 770 ka old maar of the
Pali Aike Volcanic Field, southern Patagonia,
Argentina. Due to its location the study site is
well positioned to capture the dynamics of
changes in atmospheric circulation of the
southern mid-latitudes with a time resolution out
of reach for marine sediments. This region is
also the source area of the dust that fertilises
the southern ocean with all its implications on
the global carbon cycle. Recent seismic studies
indicate that the lake basin of Laguna Potrok
Aike contains an approximately 300 m thick,
continuous sedimentary archive of geological,
environmental and climatical processes. This
record represents one of the longest and most
continuous lake archives for non-tropical South
America and the entire southern hemisphere. The
sedimentary sequence of Laguna Potrok Aike can be
recovered with coring technology available in the
framework of ICDP, i.e. using the GLAD800
drilling system. Members of the international
scientific community who are interested to
contribute to this research project are invited
to attend the ICDP Workshop to be held in Río
Gallegos, southern Patagonia (Argentina), on
March 16-19, 2006. The workshop agenda will
include an introduction to the area, reviews of
existing data and a field trip to the study site.
Special sessions will be organized to discuss and
plan specific aspects of the project such as
objectives and achievements, required laboratory
analyses and techniques, forms of scientific
collaboration, drilling sites and operations,
logistics, political as well as legal issues and
funding. Participants are expected to
collectively develop a detailed science plan
which will serve as the basis for international
multidisciplinary proposals that can be submitted
to funding agencies of participating
countries. Registration All interested
scientists are invited to apply for this ICDP
Workshop by sending name, position, contact
information and a brief abstract (1 page)
describing the intended form of participation in
the project to Bernd Zolitschka
(zoli_at_uni-bremen.de). Deadline for applications
is November 30, 2005. Participants can expect to
be notified by December 15, 2005. There is no
registration fee to attend the workshop. Limited
funding is available for all participants to
cover lodging as well as to subsidize travel
expenses. More information about PASADO and the
workshop is available at www.salsa.uni-bremen.de.

• Identifying magmatic components in fluids
  proximal to the conduit.
• Monitoring physical parameters to assess the
  hydraulic.
• Acquiring and interpreting a comprehensive
  eruption and chemical history.
• In-situ measurement of earthquakes and eruptions,
  including precursory changes.

Drilling the North Anatolian Fault
32
Drilling the North Anatolian Fault
Borehole studies and advanced monitoring effort
to provide important contributions to the
near-real time hazard assessment for the
mega-city of Istanbul. A deep borehole
geophysical observatory will be set up in close
proximity to the NAFZ near a branching point
between strike-slip and normal fault segments of
the NAFZ
33
Drilling the North Anatolian Fault

• The NAFZ Project will allow addressing key
  questions
• Is the North Anatolian Fault Zone in
  North-Western Turkey a weak or a strong plate
  boundary?
• What is the orientation of the principal stresses
  at the fault zone? Do stresses at the fault zone
  vary with depth and time?
• How does the structural heterogeneity of the
  fault affect the earthquake nucleation process?
• How is the dynamic propagation of a shear rupture
  affected by the fault structure?
• How is deformation partitioned between aseismic
  creep and seismic slip at the termination of a
  major earthquake

COREF Project Continental scientific drilling
into coral reefs near the northern limit

• The COREF Project is designed to perform
  continental scientific drilling into Quaternary
  reef-complex deposits in different settings in
  the Ryukyu Islands. Major scientific objectives
  are
• (1) To define the northern and southern limits of
  reef formation and to delineate the nature and
  magnitude of the coral-reef front migration.
• (2) To investigate the response of coral reef
  ecosystem to climatic changes on millennial to
  glacial-interglacial timescales.
• (3) To shed light on the Quaternary coral reefs
  contribution to abrupt climatic changes through a
  positive feedback mechanism in CO2 atmospheric
  concentration and carbonate precipitation.

Drilling at Campi Flegrei Caldera
41
Drilling at Campi Flegrei Caldera (Southern Italy)

• The recent unrests with a clear character of
  eruption precursors pose a high concern for a
  future eruption.
• The main scientific open questions are
• The lack of detailed knowledge about the
  geothermal systems at calderas and how they
  combine with magma overpressure and heat flow.
• The uncertainty on the presence and location of
  the shallow magma chambers.
• In addition, the way to monitor these calderas to
  efficiently detect impending eruptions.
• The economic potential related to geothermal
  energy.
• The International Workshop is aimed to focus
  these scientific questions to prepare a drilling
  proposal.
