The European Space Agency (ESA) have formally adopted Ariel, the first mission dedicated to study the nature, formation and evolution of exoplanets. CEED's Professor Stephanie Werner is a co-PI of the Ariel Consortium, which includes more than 50 institutes from 17 ESA countries, and NASA. The mission holds big opportunities for the future of comparative planetology science, and the Norway space and technical industry too. See the ESA Press release here.

Colours are often essential to convey scientific data - from weather maps to the surface of Mars. But did you ever consider that a combination of colours could be “unscientific“? Well, that’s the case with colour scales that use rainbow-like and red–green colours because they effectively distort data. And if that was not bad enough, they are unreadable to those with any form of colour blindness. Researchers from the Uni. of Oslo and Durham Uni. explain what is a “scientific colour map,” and present free-to-download and easy-to-use solutions in an open-access paper released today in Nature Communications.

A study by Ella Stokke and Morgan Jones (CEED, University of Oslo) in collaboration with Emma Liu (University College London) is published this week in the open access journal Volcanica. It presents new data on basaltic volcanic ash layers that are preserved in Danish sediments originating from the North Atlantic Igneous Province ~55 million years ago. The findings indicate that these ashes were formed by explosive hydromagmatic (water-magma interactions) eruptions, most likely as the volcanoes were submerged by the newly formed northeast Atlantic Ocean. This is by far the largest known explosive basaltic volcanism ever documented.

Like our planet’s vast surface oceans, subduction is a process unique to Earth. Active and extinct subduction zones - the surface point where one tectonic plate plunges under another - can be found all over our planet. However, we don’t know a lot about the conditions under which they initiate. A brand new interdisciplinary database on Subduction Zone Initiation www.szidatabase.org and accompanying paper has been published today in Nature Communications. The paper (Crameri et al., 2020) reviews a wide range of existing literature, presents new and clear definitions, key insights into subduction ingredients, and encourages community participation.

An open-access paper entitled “Neotectonics of the Sea of Galilee (northeast Israel): implication for geodynamics and seismicity along the Dead Sea Fault system” was recently published in Scientific Reports. It includes results of a geological study carried out by an international team of scientists from Israel, Italy, Switzerland, Norway and Germany (Gasperini et al., 2020), including CEED's Adriano Mazzini. The paper deals with the problem of earthquake generation and tectonics in a key region along the Dead Sea Fault, a major continental transform separating the African/Sinai and Arabian plates.

Researchers from the CEED Earth Crises group, led by Dr. Thea Hatlen Heimdal, have published a new study in PNAS showing that carbon release from the Central Atlantic Magmatic Province (CAMP) was responsible for major carbon cycle changes. Using a numerical carbon cycle model, they found that the release of 24,000 billion tons of carbon replicates proxy data for climate change from geological records.

In an exciting new paper out today, researchers looked to Earth's volcanoes in order to explain the formation of some lava-like flow morphologies on Mars. The mud flows on the red planet were simulated low-pressure chamber at cold temperatures, and may hold implications for other features found in the solar system! The paper, published in Nature Geoscience, was a collaborative study involving CEED Researcher Adriano Mazzini.

A research team from the University of Padova, including (returning) CEED postdoc Sara Callegaro, reported in Nature Communications (Capriolo et al., 2020) direct evidence of abundant CO2 in basaltic rocks from the end-Triassic Central Atlantic Magmatic Province (CAMP). Part of the carbon budget comes from the mantle and/or the deep crust, adding to shallower carbon sources from volcano-sedimentary basins. A degassing scenario disturbingly similar to the one mankind is responsible for in the Anthropocene.

An all-CEED team, led by Krister S. Karlsen, recently developed an Python-based algorithm that automatically generates grids of the seafloor age. Using their new algorithm now in press with Computers & Geosciences, they generated the first set of palaeo-seafloor age grids that extend back from present-day to the mid-Palaeozoic (~400 Million years ago). Using the age of the oceanic lithosphere to determine bathymetry, the grids were also used to estimate changes in sea level through time which showed good agreement with the independent sea level record.
