from exchange processes between ocean crust and
seawater
• Earth in motion: short-term geodynamic processes of
large and immediate relevance for mankind
(earthquakes, tsunamis, landslides); understanding of
fluid-flow processes in sediments and volcanic crust;
formation and stability of gas hydrates; borehole observation laboratories and their networks; and setup of
early warning systems for disasters
Despite the fact that drilling to the seafloor using
advanced technologies will provide the scientific community with samples of rocks, fluids, and gasses from environments never sampled before, the deep understanding
of Earth’s systems, but also the societal service of marine
geosciences, requires an embedding of new data into an
array of monitoring and modeling approaches. Synchronous to the demands of the estimation of risk of hazards
and projections of trends to the future, long-term instrumental data series gain increasingly importance. These
data series have to be integrated into warning systems of
disasters such as tsunamis. Besides the deep oceans, marginal seas and their coastal zones and river mouth systems
will come into focus of national and international research
projects. Studies of the modification of matter and energy
on the pathway from the source at the continents to the
sink in marine-receiving basins – including expressively
anthropogenic effects – will help to manage processes at
the interface between the terrestrial and the marine realm.
In addition to this service of marine geosciences to management and planning of natural environments in order
to find the balance between their exploitation and sustainable protection, another “classic” task will remain on the
agenda: To explore the history of planet Earth, its structure
and dynamics, as well as new potential sources for the supply of the society with raw materials and energy.
