Did you know… about worms surviving in permafrost for at least 46000 years?

Did you know… about worms surviving in permafrost for at least 46000 years?

Lately permafrost makes the news more and more because of its enormous carbon stocks and its vulnerability to climate change. While permafrost greenhouse gas budget calculations are complex and harbour an ever-growing research community, its microbial ecology is still on the rise. A recent star are tiny roundworms that survived frozen in permafrost for 46’000 …[Read More]

Survivors! Resilience and adaptations of freshwater ostracodes in ancient Lakes Petén Itzá (northern Guatemala) and Chalco (central Mexico) to climate and environmental changes over the last 80,000 years

Survivors! Resilience and adaptations of freshwater ostracodes in ancient Lakes Petén Itzá (northern Guatemala) and Chalco (central Mexico) to climate and environmental changes over the last 80,000 years

  The North American Tropics hosts lakes of diverse origins and limnological characteristics, which are located along a broad altitudinal gradient, from 0 to 5675 masl. The region possesses several ancient lakes that have accumulated sediments continuously, in some cases for >400,000 years. Study of those lake deposits has enabled scientists to infer past climate …[Read More]

Nonlinear Processes in Earth System Dynamics

Earth System Dynamics (ESD) is an open-access EGU journal focussing on an interdisciplinary view of the functioning of the Earth system and global change. Due its broad focus, ESD receives submissions of relevance to several different EGU divisions. Here, I would like to highlight five thought-provoking ESD papers that cover topics spanning environmental governance, extreme …[Read More]

Dual inward dipping subduction: A Christmas Cracker Model

Dual inward dipping subduction: A Christmas Cracker Model

A recent research finds that dual inward dipping subduction framework, after considering thermal dependent deformation mechanisms, can pull apart the middle overriding plate (Lei and Davies, 2023), just like pulling Christmas crackers from both ends! Dual inward dipping subduction (DIDS) occurs when the overriding plate is decoupled with two subducting slabs dipping towards each other. …[Read More]

Statistical earthquake forecasting – is that possible?

Statistical earthquake forecasting – is that possible?

This blog post will take you through what can and can’t be done with statistical earthquake forecasting. We are happy to have it explained by Dr. Leila Mizrahi, who is a postdoctoral researcher at the Swiss Seismological Service (SED) at ETH Zürich. Let’s get started! “My research topic is earthquake forecasting” – “Oh, really, I …[Read More]
