Phase transitions control plume layering during Earth’s secular cooling

Phase transitions control plume layering during Earth’s secular cooling

  Earth’s structure and dynamics have evolved quite a lot since its formation, and so has mantle dynamics and convection patterns changed along with it. It turns out that phase transition in certain mantle minerals can be an important driver of this change. Today, Ranpeng Li from GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany …[Read More]

One Ring to Rule Them All: The Geology of Middle-earth

One Ring to Rule Them All: The Geology of Middle-earth

Few fantasy worlds have captured the imagination of readers and viewers like J.R.R. Tolkien’s Middle-earth. Whether you first encountered it through The Lord of the Rings or the sweeping visuals of Peter Jackson’s films, chances are your eyes lingered on the same thing geologists can’t help obsessing over: the mountains. Towering, treacherous, mysterious — the …[Read More]

Tracing temperatures in tropical Lake Petén Itzá over the last 24,000 years

Tracing temperatures in tropical Lake Petén Itzá over the last 24,000 years

  Past and present global warming: its effect on the tropics According to meteorological data and climate models, global temperatures have increased by up to 1.1 °C since 1960 because of rising atmospheric greenhouse gas concentrations, including an increase in CO₂ concentrations by up to 200 ppm. In some regions, such as the tropics, home to …[Read More]

Resisting self-guilt as a PhD student

Resisting self-guilt as a PhD student

Self-guilt is a common feeling among PhD students. It often leads us to devalue ourselves more harshly than is fair and to form unrealistic expectations. It is important to understand how it shows up in our daily work, what fuels it, and how we can resist it — because over time, it can quietly undermine …[Read More]

On ice: algal blooms and the Greenland Ice Sheet

On ice: algal blooms and the Greenland Ice Sheet

On the first episode of the EGU Biogeosciences Division’s podcast series, Bikem Ekberzade interviews Helen Feord on the algal blooms that contribute to the melting of the Greenland Ice Sheet. Together with Feord, a researcher for the 5-year long project DEEP PURPLE the two scientists talk about cryosphere research, climate change and what it means …[Read More]
