The IsoMark project under the supervision of Ao Univ. Prof. Dr. Thomas Prohaska (Division of Analytical Chemistry, BOKU Vienna), was successfully completed on 31.03.2013.

Andreas Zitek has started his research visit at the Fish Ecology Lab at Woods Hole Ocenaographic Institute lasting from 27.05.2011 until 17.08.2011. The lab techniques observed there represent an important input for the Isomark project, especially with regard to the development and application of advanced analytical techniques for the analysis of isotopes in different hard parts of fish.

The second transgenerational marking experiments have been started with carps using multiple Sr isotope spikes within an official animal experiment.

A session is Co-organized by Thomas Prohaska and Andreas Zitek at the European Geosciences Union, General Assembly (EGU2011, 03.-08. April) in Vienna (Austria) at BG– Biogeosciences during the session "Application of non-traditional stable isotopes in biogeosciences". Results of the IsoMark project will be presented at this session.

The IsoMark project will be presented at the European Geosciences Union, General Assembly (EGU2010, 02.-07. May) in Vienna (Austria) at IG – Isotopes in Geosciences: Instrumentation and Applications during the session "Application of stable isotopes in biogeosciences". The EGU2010 brings together geoscientists from all over the world into one meeting covering all disciplines of the Earth, Planetary and Space Sciences.

Fourth International Otolith Symposium - 23.-28.08.2009 in Monterey California

The IsoMark project under the supervision of Ao Univ. Prof. Dr. Thomas Prohaska (Division of Analytical Chemistry, BOKU Vienna), was accepted by the FWF on 12.05.2009. The "IsoMark" project focuses for the first time on the comprehensive investigation of microchemical information (elemental fingerprint of Ca, Sr, Na, Ba, Mg; isotopic fingerprint of Sr and Ca) in different hard parts of typical European freshwater fish species like brown trout (Salmo trutta f.f., L.), European grayling (Thymallus thymallus, L.), nase (Chondrostoma nasus, L.) and the Danube salmon (Hucho hucho, L.). Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) will be used as major technique for direct and simultaneous in situ high precision analysis of trace elements and isotope ratios of hard parts. The project is run as collaboration between the Division of Analytical Chemistry (Department of Chemistry) and the Institute of Hydrobiology and Aquatic Ecosystem Management (Department of Water, Atmosphere & Environment) at the BOKU, University of Natural Resources and Applied Life Sciences, Vienna, together with the Institute for Water Ecology, Fisheries and Lake Research at Mondsee/Scharfling (Federal Agency for Water Management), and is directly related to the research of the START-project "VIRIS" (Vienna Isotope Research Investigation and Survey, FWF 267-N11).
