Lab Training HS 2018

39453-01 Methods in Environmental Geosciences: Principles in Aquatic Biogeochemistry - Fall Semester 2018

During the basic lab training in aquatic biogeochemistry, Bachelor students were sampling water all around Basel, like the Birsig, Wiese and Rhein. The main goals are to get a better understanding of analytical methods in the lab as well as to investigate the water quality in and around Basel.

Zschokke Haus in Engelberg

Fun & Sciences - Zschokke Haus Engelberg

In February, we spent two exciting days in the Swiss Alps near Engelberg, where everyone presented his/her projects. Great scientific exchange, and a lot of fun in the snow. Zschokke Haus, we will come again!

Lake Cadagno

Winter Sampling Cadagno (18/19 April, 2018)

Lake Cadagno is a small meromictic lake in the southern Swiss Alps at 1921 m altitude. It is a well-established model system for an Early Earth Ocean. The biogeochemical processes operating during the short summer months have been investigated in great detail. But the lake is difficult to access in winter and therefore not much is known about the physical and chemical conditions under the ice cover. Even less is known about the microorganisms dwelling in the dark, cold water and the biogeochemical processes they are driving. A team from the Biogeochemistry Group, Jessica, Paul, Maciej and Jakob, set out to explore the wintertime microbial communities and to determine how much of the greenhouse gas methane is produced and trapped under the ice cover.

Cruise 2018

Sea- going expedition to the tropical pacific with the SCRIPPS vessel R/V Sally Ride

Post doc, Claudia Frey, participated in a 6 weeks long cruise lead by PI Prof. Bess Ward to the Tropical pacific. Starting off in San Diego, U.S.A. we took over 6000 water samples within 6 weeks on our way to Manzanillo, Mexico.
The goal was to resolve exactly where and how much nitrous oxide is produced and consumed by ocean microbes. For that we analysed the level of nitrogen and oxygen at different depths. Knowing the origins and sinks of the powerful greenhouse gas, N2O has significant implications for modeling global warming. Microbes produce more than half of the planet’s nitrous oxide, which is not only contributing to climate change but also destroying our protective ozone layer.
The pictures not just give an impression of how we get the water samples and how we process them, but also on the beauty of the sea.
