As a member of the UEA Glider Group, I have been involved with deployments of oxygen sensors (optodes) on autonomous float (NAB 2008) and glider (GOPINA) platforms, in order to provide vital data on the oceanic carbon cycle and biological productivity estimates in a changing climate. More recent work included studies of N2O and nitrate in marine and terrestrial environments as well as measurements of the chlorine (37Cl/35Cl) and carbon (13C/12C) of volatile organic compounds.

The small 17O-excess of atmospheric N2O motivated me to consider how best to characterise such anomalies. AIESEC Alumni View graph of relations Oxygen/argon ratios allow separation of physical and biological effects on gas concentrations and provide net community production estimates on unprecedentedly fine scales. Jan Kaiser is on Facebook. In laboratory experiments, I studied temperature- and wavelength-dependent isotope effects in N2O photolysis. Jan Martin Tel. I study global chemical, physical and biological processes in the Earth's atmosphere and oceans, and their variations through time under natural and anthropogenic influences, by integrating fieldwork, laboratory studies and modelling into a coherent framework, often involving the use of stable isotopes.

Δ(17O) combined with nitrogen isotope ratios were used to understand the annual cycle of nitrate in coastal Antarctica, uncovering stratospheric influences and re-evaporation from surface snow. My review of data reduction practices for CO2 isotope measurements revealed systematic uncertainties in global carbon budget calculations.

Low sample size requirements make this technique suitable for ice core studies of past changes in the atmospheric oxidation capacity. Katharina Jahnke MSc R 3020, voice: (+49)761-203-6228 E-mail: Katharina.Jahnke I discovered that during photolysis the central nitrogen position always becomes more enriched in 15N than the terminal one, but that during photo-oxidation the opposite position-dependent fractionation occurs. University of East Anglia, Norwich Research Park, Norwich, Norfolk, NR4 7TJ, UK. Lehrbeauftragter an der Albert-Ludwigs-Universität Freiburg . This pattern allowed me to distinguish photolysis and photo-oxidation in the stratosphere. Branchenzuordnung.
