vEGU21 BG sessions in the spotlight: deep time to recent past

vEGU21 BG sessions in the spotlight: deep time to recent past

The deadline for vEGU21 abstract submission is coming closer – here is the second blogpost where we highlight a few sessions across the five BG themes, today from the General Biogeosciences sessions pool and with a focus on deep time and the recent past. To foster a discussion of the reconstruction of ecological baselines and natural range of variability for a better understanding of the lon ...[Read More]

vEGU21 BG sessions in the spotlight: social geosciences, resilience and policy making

vEGU21 BG sessions in the spotlight: social geosciences, resilience and policy making

The deadline for vEGU21 abstract submission is coming closer – over the course of the next two weeks, we highlight sessions across the five BG themes, starting with General Biogeosciences sessions focused on social geosciences, community and earth resilience, health and urban systems and geoscience knowledge transfer to policy and society. With Social Geosciences: A New Paradigm to Character ...[Read More]

At the heart of biogeochemistry: pH change interpretation & open peer-review

At the heart of biogeochemistry: pH change interpretation & open peer-review

The utility of logarithmic scales is nothing new to scientists – yet, sound interpretation of pH changes when comparing settings with different initial pH can be challenging. This blogpost highlights a manuscript by Fassbender et al. [1] that was recently submitted to the journal BG and is currently under open peer review. The pH scale was first published by Søren Peter Lauritz Sørensen in 1909 [2 ...[Read More]

High-resolution biogeochemistry: Taking snapshots of past climate using mollusk shells

High-resolution biogeochemistry: Taking snapshots of past climate using mollusk shells

This is a solicited blogpost written by Niels de Winter. Now that the effects of rising anthropogenic CO2 emissions are starting to affect our everyday lives, accurate reconstructions of past climates become more and more relevant. These reconstructions help us to improve climate models used to project future global warming scenarios which in turn inform policy makers. The further we look back in ...[Read More]

Dating mineral phases in geological remnants of early life

Dating mineral phases in geological remnants of early life

This is a solicited blogpost written by Sebastian Viehmann. The Mesoarchean Strelley Pool Formation in the Pilbara Craton (Western Australia) hosts one of the oldest geological remnants of life on Earth. These silicified stromatolitic carbonates show diverse morphologies and formed on a shallow marine carbonate platform 3.35 billion years ago (Ga; Figures 1 and 2). After a long-standing debate abo ...[Read More]

Phosphorus-cycle perturbations and environmental disturbances 380–360 million years ago

Phosphorus-cycle perturbations and environmental disturbances 380–360 million years ago

This is a solicited blogpost written by Lawrence Percival, who will also present his work on the Oceanic Anoxic Event 2 as part of session SSP2.1 of the upcoming EGU GA.   The increasing concern regarding 21st climate change and environmental disturbance has led to a renewed focus on similar episodes of global crisis through Earth’s history. During the Late Devonian Period, 380–360 million ye ...[Read More]

EGU2020 BG Sessions in the spotlight: Extreme environments

EGU2020 BG Sessions in the spotlight: Extreme environments

Less than one month left for the EGU 2020 abstract deadline on January 15. Today we highlight two sessions of BG 5 – Geomicrobiology, extreme environments on Earth and planetary analogues.   First, BG5.1: Biology and Geology of extreme environments on Earth and planetary analogs. This session is convened by Monica Pondrelli, Jessica Flahaut, Frances Westall, Helge Niemann and Barbara Cavalazz ...[Read More]

EGU2020 BG Sessions in the spotlight: Methane

EGU2020 BG Sessions in the spotlight: Methane

The EGU 2020 abstract submissions are open until January 15. Here, we’ll highlight the planned biogeosciences sessions. Stay tuned and find the session for your abstract! Today’s focus is on Methane. Methane, a potent greenhouse gas, is steadily increasing in concentration in the atmosphere, prompting fears that it could scupper our chances to meet the global climate targets. But given its relativ ...[Read More]
