Microbes and oceanic sulfate, a sulfurous story

Author: Laetitia Guibourdenche (IPGP, Paris) « I was engaged a few years ago in a course of experiments on hydrogen gas, which was procured in the usual method, by the solution of iron turnings in diluted sulphuric acid. The sulphate of iron hence resulting, (…) remained undisturbed, and unnoticed for about a twelve month. At the … Continue reading Microbes and oceanic sulfate, a sulfurous story

Eustasy and the Messinian: was the MSC the cause or result of global sea-level change?

Author: Hanneke Heida (Institut Ciències de la Terra Jaume Almera (CSIC), Barcelona - Spain) Over the last century, global sea-levels have been rising at a steadily increasing pace, driven by melting glaciers and continent-based ice sheets and thermal expansion of ocean water. The current pace of the rise of sea level is estimated to be … Continue reading Eustasy and the Messinian: was the MSC the cause or result of global sea-level change?

FINAL MEDSALT SYMPOSIUM 2020 – PIRAN, SLOVENIA

Author: Athina Tzevahirtzian (Università di Palermo) https://www.youtube.com/watch?v=Fwu_YiTZirs The study of the unique Mediterranean salt giant started well before the nowadays SALTGIANT ETN (2018 – 2021). On March 2016, another European project began, entitled COST Action CA15103 “Uncovering the Mediterranean salt giant (MEDSALT)”. The MEDSALT project has included a critical mass of both experienced and early-career … Continue reading FINAL MEDSALT SYMPOSIUM 2020 – PIRAN, SLOVENIA

How a shrinking ocean helped global cooling: a story of feedbacks

Author: Francesca Bulian (Universidad de Salamanca, Spain) In our blog, Federico already tackled the amazing concept of a disappearing sea, emphasizing how rising of new mountain chains and consequent lend-sea redistribution impacts marine basins. These geological changes can happen on different time scales, from less than a million up to hundreds of millions of years … Continue reading How a shrinking ocean helped global cooling: a story of feedbacks

From Fossil fuel exploration to underground storage and geothermal energy: Why do we care about Salt tectonics?

Author: Simon Blondel (OGS Trieste) Giant, halite-dominated salt accumulations are common on Earth. Throughout the human history, they have been mined for their salt that was used for animal nutrition, food conservation, de-icing etc. Compared to the other rocks, halite itself is quite a peculiar material characterized by: a low density;a low permeability;a high solubility … Continue reading From Fossil fuel exploration to underground storage and geothermal energy: Why do we care about Salt tectonics?

The rugged reefs of Mallorca: the key to the Messinian story in the Western Mediterranean?

Authors: Hanneke Heida (ICTJA, CSIC - Barcelona), Fadl Raad (CNRS Montpellier) and Athina Tzevahirtzian (Universitá di Palermo). Last September our ESRs Hanneke Heida, Fadl Raad and Athina Tzevahirtzian had the opportunity to enjoy an Indian Summer investigating the fascinating Messinian outcrops of the island of Mallorca, in the Balearic archipelago.  Hanneke, Athina, Fadl and Professor … Continue reading The rugged reefs of Mallorca: the key to the Messinian story in the Western Mediterranean?

Imagining the Mediterranean’s past: Why historians of science should take imaginaries into account?

Author: Beatriz Martínez-Rius (Sorbonne Université, Paris) I bet that all of us have tried to imagine how the Mediterranean looked like 5 million years ago. We’ve tried to draw it, model it, animate it, and depict it through scientific representations of all sorts. When we talk about partial desiccation, reflooding, isolated basins… we are exercising … Continue reading Imagining the Mediterranean’s past: Why historians of science should take imaginaries into account?
