Disputas - Master of Science Knut Ola Dølven

Master of Science Knut Ola Dølven will on 24 March at 12.15 publically defence his thesis for the PhD degree in Science.

Title of the PhD thesis:

« Measuring Methane in the Arctic Ocean - From legal framework to time series analysis via technology innovation »

Popular scientific abstract: 

To reach international agreement on solutions to solve climate change and a sustainable future, a thorough understanding of environmental processes is crucial. Methane seeping from the seabed in the Arctic Ocean can cause climate change and is not well understood and more data is needed. This thesis have approach this problem from mainly an oceanographic, but also legal perspective. An inter-disciplinary assessment show that the implementation of innovative technology is not currently being hampered by legal issues. Two long-term time series from two intense methane seep sites offshore West Spitsbergen show very high variability on short time-scales which highlights the potential for errors in budget estimates. Lower concentration towards winter is explained by stronger mixing and winter storms. We developed a new technique for monitoring seabed seepage using an acoustic ocean current meter and also a method for retrieving fast response data from slow response methane sensors.
