Crater lakes hold important value as sites of cultural heritage and geoheritage. These unique aquatic ecosystems can also provide a valuable window into environmental transitions at both local and global scale. Due to their distinctive morphology, these closed systems have the potential to accumulate continuous, high-resolution records of environmental variability. Yet others are highly volatile systems bearing evidence of abrupt environmental changes. This session invites a wide variety of contributions discussing natural or human imprints in the physicochemical or biological features of the water column and/or the sedimentary record of crater lakes. Potential topics include, but are not limited to, patterns and consequences of climate variability – from long-term trends to short-term fluctuations and from recent times to the distant past – as well as of a suite of human perturbations affecting these peculiar systems. The session is open to research contributions drawing on paleolimnological time-series, modern observation, experimentation or modeling, and welcomes especially research integrating multiple approaches.
