The research used experimental transplants and reef surveys at 12 islands within the Chagos Archipelago to compare coral reef dynamics following a coral bleaching event (2015) between islands with natural nutrient influx from seabird populations and those with low seabird presence (rat-infested islands). 📜 https://lnkd.in/gbvfAXgy

NEW Paper published in Science! 🌊 A climate-change-triggered landslide caused Earth to vibrate for 9 days Belgian researchers are involved in a study lead by an international multidisciplinary team🌊 In September 2023, a mysterious, globally observed and unprecedented 9-day-long seismic signal was caused by a massive landslide in Greenland. 25 million m³ of rock and ice fell into the Dickson Fjord and, in turn, caused a 200-metre-high mega-tsunami that continued sloshing back and forth – a phenomenon called a seiche – in the narrow fjord for 9 days.That is the conclusion of research published in the journal Science. The seismic waves generated by this large mass of moving water have been observed around the world. Never before have scientists, including researchers of the Royal Observatory of Belgium, the VLIZ - Flanders Marine Institute and the ULB, observed such an unusual mechanism causing a global seismic signal.

Researchers from the University of Science and Technology of China have uncovered key insights into the origin and early evolution of nitrogen on Earth. They studied the fractionation of nitrogen isotopes during the formation of terrestrial planets, revealing that both early planetesimal processes and late accretion of volatile-rich materials contributed to Earth's nitrogen composition. This research provides a new understanding of how nitrogen, essential for life, accumulated on our planet. For more details, you can read the full article here: https://lnkd.in/ekDRa75B

Dear connections, I am happy to share an important publication on the interplay between ocean surface waves and oceanic biogeochemistry. This study is a part of my PhD thesis. I am grateful to all the authors for their contributions in this study. A plain-language abstract is given below: The Southern Ocean is home to the world’s strongest winds and largest surface waves. These features play a crucial role in global climate through various processes like ocean mixing, heat transport, and biogeochemical cycles. However, present-day studies lack investigation into the impacts of these large waves on the Southern Ocean’s biogeochemistry, for instance, how ocean surface waves influence microscopic plants in the ocean, called phytoplankton. This study is the first of its kind to investigate the impacts of surface wave mixing on oceanic biogeochemistry, especially on phytoplankton dynamics. Additionally, given the changing wind and wave climate in the Southern Ocean, this study further underscores the implications for shifting marine ecosystems and biogeochemical processes in the region.

For the first time, Utrecht University's Earth Sciences research secured a spot in the Guinness Book of World Records! 📙 Dr. Dan Palcu's groundbreaking research on the Paratethys, the largest lake ever documented on Earth, played a crucial role in precisely measuring the dimensions of the lake. The research team employed magnetostratigraphy, a technique leveraging the reversals of the Earth's magnetic field to date sediment layers from ancient times. "Our exploration of the Paratethys goes beyond mere curiosity. It unveils an ecosystem acutely responsive to climate fluctuations," says Dr. Palcu 🌎. By exploring the cataclysms that this megalake endured as a result of climate shifts, they gained invaluable insights that can unravel the path to addressing current and future crises in toxis seas, such as the Black Sea.

Romain is defending his PhD on magnetotellurics in the SW Barents Sea on January 26th 1:15pm CET at the Department of Geosciences, University of Oslo (UiO) https://lnkd.in/dTFJENgP Popular science summary: The sun’s energy can interact with the Earth’s magnetic shield, which can be used to expose different structures in the Earth’s interior. In this thesis, we present a new model of geoelectrical structures beneath the Barents Sea obtained with an automated trial and error process called inversion. Our results suggest that the brittle crust can become so severely stretched that saline water can circulate and react with the upper mantle. This reaction releases hydrogen, a potential source of carbon-free energy.

A great talk from Dr. Laurie TCHANG-TCHONG from GeoRessources, Universite de Lorraine at the seminar of the 4.8 Geoenergy section at the Helmholtz-Centre Potsdam - German Research Centre GFZ, who presented today the results of her PhD research on the thermicity of the Pechelbronn sub-basin and insights of the fluids transfers in geosystems, in the framework of DEEPSURF. #geothermal #science #upperrhinegraben #georesources #deepsurf

I am pleased to share information about a new PhD Candidate position in Earth Sensing at NTNU (Trondheim, Norway). The research topic concerns the nature of long-term CO₂ migration and retention, by looking at natural CO₂ fluxes, earthquake datasets and tectonic strain models. See link below
