dr Frits | 16 juni 2023 |
Frits Steenhuisen, mijn collega op het Arctisch Centrum, heeft vandaag succesvol zijn proefschrift verdedigt en is nu Doctor of Philosophy. Frits is een specialist op het gebied van vervuiling, databases en geographische informatien systemen. Zijn proefschrift had als titel Global mercury emissions and distribution, an Arctic perspective. Frits is meerdere keren op het poolstation geweest, waar hij onderzoek deed met mij, martine en Gijs.. Foto's door Lex Ligfiets | |
In 45 minuten stelden 8 mensen vragen aan Frits. Drie commissieleden waren online en ontbreken op bovenstaande foto: Kees Bastmeijer (vanuit Venetië) and Maarten Loonen (vanuit Ny-Ålesund) als zijn collega's van het Arctisch Centrum, en Elsie Sunderland van Harvard University. Gijs Breedveld en Richard Bintanja waren de promotoren van Frits waarbij Gijs uit Longyearbyen was gekomen. | |
De dag voorbereiden. | |
Er was maar 4 minuten tijd voor mijn discussie met Frits. Esteemed candidate, Thank you for your thesis. It is a condensed format of all the relevant work you did for the Arctic Monitoring and Assessment Program, the working group of the Arctic Council focusing on pollution. Your expertise has always been in crunching large databases and visualization of geo-information and I am looking forward to continue working with you on remote sensing. Now going to your thesis. In several locations in your thesis, I read that there are three types of mercury emissions: anthropogenic, legacy and geogenic. What are legacy and geogenic emissions in the Arctic? Wildfires are an important source for legacy emissions. Did you hear the news about recent wildfires in Canada and the consequences for New York? I am wondering if the effect of modelling of legacy mercury would show export of mercury from the Arctic to lower latitudes, creating a kind of opposite effect as you showed in your outreach project of two earths with emission and deposition patterns as shown on page 30 and 45. The Arctic strikes back. | |
