role of non-growing and shoulder season carbon and nitrogen dynamics with soil-atmosphere CO 2, CH 4 , and N 2 O exchange quantification in pristine northern ecosystems. The effects of soil freezing and [...] cores, as well as their influences on climate. He has a keen interest in cosmogenic radionuclides (14C, 10Be, …) and how we can use them to learn more about (paleo-)climate dynamics, the Sun, and Earth’s [...] the Pacific Southern Ocean, and its linkages with changes in the Antarctic ice sheet, atmospheric CO2, and global climate. For this purpose, he will use sediment material obtained during the IODP Expedition
