What causes ozone depletion events and bromine explosions in the polar atmosphere. 100+ specjalistów o nazwisku „Jan Kaiser” korzysta z LinkedIn, aby dzielić się informacjami, pomysłami i możliwościami kariery. In laboratory experiments, I studied temperature- and wavelength-dependent isotope effects in N2O photolysis. Ulrike Föhner Tel. The small 17O-excess of atmospheric N2O motivated me to consider how best to characterise such anomalies. This approach has been applied to nitrous oxide (N2O), nitrate, oxygen, nitrogen, argon and CO2. I am also interested in rare isotope signatures, such as oxygen isotope anomalies (17O-excess, Δ(17O)) and multiply-substituted isotopologues (clumped isotopes) such as 15N15NO.

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. Machen auch Sie sich ein Bild! Oxygen/argon ratios allow separation of physical and biological effects on gas concentrations and provide net community production estimates on unprecedentedly fine scales. seit 1996.

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. However, feel free to email me to discuss projects outside these areas and alternative sources of funding.

My review of data reduction practices for CO2 isotope measurements revealed systematic uncertainties in global carbon budget calculations.

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.

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.
