Biogeosciences in the blue zone- COP26.

COP26 plenary room

Our Editor, Ben Fisher, writes about his experience as an observer at COP26 and the representation of biogeosciences in the negotiation area.  I was extremely fortunate to have the opportunity attend the second week of COP26 as a delegate of the Scientific Committee on Antarctic Research (SCAR). Having been a rather last minute addition to the attendance list (I found out I’d got credentials ...[Read More]

From the forest to the ocean – get to know the new ECS representative team of the Biogeosciences division!

From the forest to the ocean – get to know the new ECS representative team of the Biogeosciences division!

The Biogeosciences division is among the most diverse in the EGU, from marine and terrestrial sciences to extraterrestrial studies and remote sensing applications. Therefore, there is a need of a team of ECS representatives covering a wide range of research interests and topics. Do you want to know them?     Elisabet Martínez-Sancho is a postdoctoral researcher at the Swiss Federal Insti ...[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]

Investigation of methane emissions in marine systems

Investigation of methane emissions in marine systems

Ever wondered how we can measure methane emssions from the seafloor ? And ever wanted to steer a mini submarine remotely operating vehicle (ROV)? Well here´s your chance! Have look at this blog post on analyzing methane emissions using ROVs and you´re ready to embark!    The goal is to determine when the gas leak started and how the fluid flow systems work. With our research, we can contribut ...[Read More]

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

As climate change progresses, widespread changes in phenotypes in many plant populations are bing observed by scientists around the world. For instance in alpine areas, dominant plant species on lower altitude are shifting towards higher altitude as they adapt to increasing temperatures, thereby competing with high-altitude native plant species. In a recent study by Petry et al. (2016) it was show ...[Read More]

Keeping a lookout at the edge of the world

Keeping a lookout at the edge of the world

  Few places in the world conjure up images of remoteness and harshness like Far Eastern Siberia. Yet, it’s places like these where our science is needed most. Arctic soils hold vast amount of carbon, protected in thick layers of permafrost, but these stores are becoming more and more vulnerable as temperatures in the Arctic warm, and are set to warm faster than anywhere else on the planet. R ...[Read More]

Digging up bones for science – looking into 48 million years old blood vessel-like structures

Digging up bones for science – looking into 48 million years old blood vessel-like structures

The Messel Pit is a worldwide famous fossil site recognized by UNESCO as a World Natural Heritage Site because of the exceptional preservation, as well as the diversity of its fossils from the early-middle Eocene (~48 Ma). The Messel Pit, located in an old Quarry in Germany near Frankfurt am Main , includes fossils from vertebrates (turtles, crocodiles, mammals, birds, lizards, among others), inve ...[Read More]
