EGU2020 BG Sessions in the spotlight: Permafrost

EGU2020 BG Sessions in the spotlight: Permafrost

The EGU 2020 abstract submissions are open until January 15. Here, we’ll highlight the planned biogeoscience (BG) sessions. Stay tuned and find the session for your abstract! Today’s focus is on permafrost. These perennially frozen regions span the Arctic, the Tibetan Plateau, and mountain regions throughout the globe. Permafrost is highly vulnerable to current and future climate change and could ...[Read More]

Understanding the role of microbes in cold seep habitats

Understanding the role of microbes in cold seep habitats

A cold seep is an area of the ocean seafloor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs. These parts of the ocean floor still remain a large mystery for scientists, in particular for the occurence of hydrothermal vents. In between these vents, microbes live that play a role in the local and global carbon budget. However their exact role remains largerly unknown ...[Read More]

Identification of past methane emission altering the foraminiferal tests by secondary overgrowth of calcium carbonate.

Identification of past methane emission altering the foraminiferal tests by secondary overgrowth of calcium carbonate.

Ever heard about foraminifera? These tiny benthic (living at the seafloor) marine organisms are common in oceans across the globe and can be used to accurately give relative dates to sedimentary rocks. But we can also use them to identify past methane emissions from the seabed by studing their test or shell!   The measurements were done on foraminifera called Cassidulina neoteretis , which is a ty ...[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–high resolution δ18O record from bivalves

Coffee break biogeosciences–high resolution δ18O record from bivalves

Much like trees, clam shells have growth rings. The chemistry of these rings can be used as a proxy for ocean chemistry. Recently, an international team of scientists used the growth rings found in shells of Arctica islandica to produce an annual absolutely dated marine δ18O record for the last millennium which was published in Nature Communications. The record represents the first fine scale arch ...[Read More]

Coffee break biogeosciences – New coral reef at Amazon river mouth discovered

Coffee break biogeosciences – New coral reef at Amazon river mouth discovered

At the Amazon river mouth, a huge 9,300 sq km coral reef system has been found below the muddy waters off the mouth of the river Amazon. As corals mostly thrive in clear, sunlit, salt water, and the waters near the mouth of the Amazon are some of the muddiest in the world, the discovery of this almost 2000 km long reef leaves scientists puzzled about the potential extent of coral reefs worldwide. ...[Read More]
