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]

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]

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]

The Panamanian Isthmus is not entirely guilty after all!

Diana Ochoa December 8, 2015

Fieldwork in northwestern Colombia, in order to recognize the nature, structure and mineral composition of fluvial deposits accumulated during the middle Miocene. Within these sediments, detrital zircons of Panamanian affinity were commonly found and used to determine an earlier land connection between Central and South America (credit: Lina Pérez-Angel).

“According to new research, the land bridge connecting Central and South America rose more than 10 million years earlier than originally thought” Traditionally, closure of the Panama Isthmus has been deemed responsible for the co-occurrence of two major events: The large Pleistocene glaciations and the Great American Biotic Interchange (GABI). Existing evidence indicating a ca ...[Read More]
