Impact of persistent droughts on forests in Mediterranean Chile

Global warming is concurrently associated with a rise in occurrences of drought episodes in numerous regions worldwide, with central Chile a sad example. This region is the only Mediterranean bioregion of South America, which is considered a biodiversity hotspot due to high endemism levels and high anthropic pressure. These ecosystems since 2010 have been impacted by a period of below-average rainfall, a so-called Mega Drought (MD), so their contribution to the regional carbon sink is at risk.

State-of-the-art radiocarbon measurements to study Earth's carbon cycle

The development of high-precision, rapid through-put radiocarbon dating for small samples via a compact accelerator mass spectrometer — the MIni CArbon DAting System (MICADAS) — has opened a wide variety of new possibilities for next generation radiocarbon studies. This talk will explain the basics of the instrumentation (which will be installed in the Laboratory of Tree-Ring Research in 2024) and explore a variety of examples of the ways in which it can be used to explore the carbon cycle and beyond.
