Mass independent oxygen isotope fractionation (MIF)
Molecules containing the element oxygen can be further characterized by the distributions of the
stable oxygen isotopes 16O, 17O and 18O. In some cases, these isotopes have an anomalous
distribution, which is evidence of Mass Independent Fractionation (MIF). Although it is new,
MIF has become a powerful research tool in earth system science because it is a sensitive marker
of particular chemical reactions. Because MIF is a clear signature that cannot be erased, its use
is expected to spread from the core science disciplines to industrial applications.
The INTRAMIF Network
With INTRAMIF, we bring together experts from atmospheric and climate research, hydrology,
oceanography and molecular physics and provide training in these areas for 13 talented
Early Stage Researchers (ESR).
The ESR projects from the different disciplines are connected by the common theme of MIF.
Sharing expertise and world-class facilities will allow the individual groups to do research
that would otherwise be impossible. This will give the network an impact far beyond the sum of
the separate groups' activities and will create a center of excellence for MIF research
in Europe.
Non-academic partners
The associated industrial partners of INTRAMIF will integrate the research and training programs
with real-world opportunities. For example, our partnership with Thermo Fisher Scientific (Bremen),
a leading analytical instrument company, will promote the commercialization of instrumental
methods developed within INTRAMIF. In partnership with environmental consulting and testing firms
and the food industry, INTRAMIF will promote the application of MIF to solve present and future
questions on water supplies and food authentication.
Science objectives
Our common scientific goal is use MIF signatures as unique tracers to investigate processes in the
environment. For this purpose we will follow the anomaly through the different reservoirs, from its
production during ozone formation into other key atmospheric trace gases and particles, and ending
in water and ice cores. Concrete objectives are:
- To further understand MIF processes and the transfer from ozone to other compounds
- To constrain anthropogenic nitrogen inputs to water bodies and soils
- To study the relations between global biological productivity and climate change
- To reconstruct the past history of the atmospheric oxidation capacity
- To use the three oxygen isotopes to investigate the global water cycle
Overreaching objectives
Climate change is a key challenge for society. The INTRAMIF scientific program describes how MIF
will be used to investigate the earth system and obtain knowledge not available via other methods.
The broad basis of the scientific program allows us to combine specialized training in individual
disciplines at the host institutions with a unique interdisciplinary and intra-sector network
training program on the climate system involving associated partners from the industrial, political
and economic sectors. The strong interest from our associated partners documents the need for highly
qualified scientists with a wide interdisciplinary background that we will educate in INTRAMIF. The
overreaching objectives of INTRAMIF are:
- To educate the next generation of scientists by combining a solid scientific foundation with a
broad interdisciplinary background to solve new challenges to society in a changing climate
- To keep Europe at the forefront of this new scientific field by making strategic use of
synergies in infrastructure and complementarities in knowledge between the network partners.
- To transfer knowledge from the science community to industry in order to develop new industrial
applications beyond climate research.
- To improve scientific understanding in areas of EU policy goals, e.g. the use of MIF in nitrate
and water (EU Groundwater Directive), in ozone and aerosols (EU Air Pollution Directive), and in
ice cores (EU Strategy on Climate Change).
- To provide added value to the classical scientific education and thus produce ESRs who are
attractive candidates for careers both inside and outside of academia.
