Elements: Catastrophic Perturbations to Earth's Deep Carbon Cycle

October 14, 2019

This issue explores the origins of carbon on Earth; the long-term carbon cycle; catastrophic and large-scale perturbations to Earth's carbon cycle such as large igneous provinces and bolide impacts; carbon's role in mass extinctions; and icehouse–greenhouse climate transitions in deep time. Deciphering the complex, and often faint, signals of distant carbon catastrophes requires a multidisciplinary effort and the most innovative analytical technology. This thematic collection comes at an important time in which carbon fluxes on Earth are changing rapidly.

Meet the Scientist: April Abbott

September 20, 2019

Name: Dr. April N Abbott
Institution: Macquarie University
Place Of Residence: Australia

What kind of science do you do?
I'm a geochemical oceanographer- I use pore water (the water between the sediment grains) to understand modern element cycling and their implications on paleoclimate studies. Currently, I'm focused on understanding whether the sediments are a source of rare earth elements to the overlying water column.

Elements: Weathering Across the Earth Sciences

July 29, 2019

Weathering processes play and integral role across a range of geoscience fields. Chemical weathering – the loss of mass by mineral dissolution and export – is key to understanding how Earth's skin functions. Weathering is the starting point for the biogeochemical cycles of most elements. It determines river and groundwater chemistry and provides nutrients to ecosystems. Weathering alters rock structure and susceptibility to erosion; soil and landscape evolution cannot be understood without considering the role of chemical weathering. Weathering of silicate rocks is a long-term sink for atmospheric CO2, and has been crucial in maintaining our planet's habitability over billions of years ... and may constitute a geoengineering strategy. This issue explores the linkages between them.

Meet the Scientist: Nurgül Balci

July 24, 2019

Name: Nurgül BALCI
Title: Professor
Institution: Istanbul Technical University, Department of Geological Engineering, Ayazaga Campus
Place of Residence: Istanbul, Turkey


What kind of science do you do?
I am a geomicrobiologist dealing with microbe-mineral interactions in extreme environments (e.g acidic, hypersaline, hot springs) to understand evolution of life on Earth and other terrestrial planets in our Solar System. Also, I would like to understand geochemical conditions of the early Earth and how life started to flourish. By doing this kind of research I am hoping that one day as humans we will explore the other planets and find a backup place.

Meet the Scientist: Aisha Al Suwaidi

June 19, 2019

Name: Aisha Al Suwaidi
Title: Associate Professor in Earth Sciences
Institution: Khalifa University of Science and Technology
Place of residence: Abu Dhabi, UAE


What kind of science do you do?
I try to understand how the carbon cycle has changed through the Mesozoic (occasionally I work on more recent things like the Paleocene-Eocene ~55 million years ago), but mostly I am very interested in understanding how long it takes the Earth to recover from carbon cycle perturbations, mass extinctions and anoxia in the oceans associated with large igneous province activity hundreds of millions of years ago.

Elements: South Aegean Volcanic Arc

June 13, 2019

The South Aegean volcanic arc lies at the intersection between Europe, Asia, and Africa, in the cradle of European civilization. Studies over the last decade have transformed our understanding of the arc: subduction architecture and back-arc geodynamics, genesis of the arc magmas, eruption chronology of the arc recorded in marine tephra archives, and hazards posed by eruptions and tsunamis. The volcanoes (e.g., Santorini) in this region have a long history of impacting on human civilization. The articles in this issue present a closer look at the igneous and tectonic processes and hazards that affect this region.
