Centre for Ocean and Atmospheric Sciences, Interdisciplinary Institute for the Humanities, Politics, Philosophy, Language and Communication Studies, 'Stable isotope investigations of atmospheric nitrous oxide', 'Sulphur isotope exchange and disproportionation of thiosulphate'. Contact. Deadline: 12 January 2021. The small 17O-excess of atmospheric N2O motivated me to consider how best to characterise such anomalies. 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.

Kaiser Group website: https://kaiserlab.org. This approach has been applied to nitrous oxide (N2O), nitrate, oxygen, nitrogen, argon and CO2. I have led studies on the isotopic composition of atmospheric N2O, emphasizing position-dependent 15N/14N isotope ratio measurements and the fate of N2O in stratospheric photolysis and photo-oxidation. 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. Telephone: +44 (0) 1603 456161 Accessibility Legal Statements . I developed analytical methods to accurately measure N2O isotopes in troposphere, stratosphere, polar firn air and ice.

Jan KAISER, Professor of Biogeochemistry of University of East Anglia, Norwich (UEA) | Read 168 publications | Contact Jan KAISER The N2O work led on to the first online gas chromatography-isotope ratio mass spectrometric method to measure Δ(17O) of nitrate, which drastically reduced sample sizes and enabled seawater analyses. What causes ozone depletion events and bromine explosions in the polar atmosphere. Jan Kaiser betreibt in Uslar zwei Rewe-Supermärkte die von der Rewe-Nord beliefert werden. 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. I have also developed a sea-going membrane inlet mass spectrometer (MIMS). Auch Stellenangebote von Jan Kaiser (Rewe) können Sie hier finden.
