A new, high-resolution mapping framework will enable accurate forecasts of crop water use, according to research published in the EGU journal Hydrology and Earth System Sciences.
The European Geosciences Union (EGU) and its partner Copernicus are announcing the launch of EGUsphere, a new online platform designed to increase visibility and boost discussion and collaboration within the Earth, planetary and space science community.
The EGU invites applications for the Union’s new programme of grants designed to fund the preparation of higher education (university-level) geoscience teaching packages. The deadline is 1 June 2020.
The support will allow Kalvelage to report on cold-water coral ecosystems in the Mozambique Channel, Irwin to travel to Germany to investigate new extraction and processing methods for obtaining rare earth elements, and Dumas to follow scientists to several European locations to search for evidence that humanity has entered a new geological epoch.
Sea-level rise due to ice loss in Antarctica could become a major risk for coastal protection even in the near term, scientists say. Within this century already, due to Antarctica alone, global sea level might rise up to three times as much as it did in the last century, according to research published in the EGU journal Earth System Dynamics.
We have confirmed that there is a supertidal cycle associated with the supercontinent cycle. As continents drift due to plate tectonics, oceans also change size, controlling the strength of the tides and causing periods of supertides. In this work, we used a coupled tectonic–tidal model of Earth’s future to test four different scenarios that undergo different styles of ocean closure and periods of supertides. This has implications for the Earth system and for other planets with liquid oceans.
We test the approach of producing global gridded carbon fluxes based on combining machine learning with local measurements, remote sensing and climate data. We show that we can reproduce seasonal variations in carbon assimilated by plants via photosynthesis and in ecosystem net carbon balance. The ecosystem’s mean carbon balance and carbon flux trends require cautious interpretation. The analysis paves the way for future improvements of the data-driven assessment of carbon fluxes.
Methanethiol (MeSH) is a reduced sulfur gas originating from phytoplankton, with a global ocean source of ~ 17 % of dimethyl sulfide (DMS). It has been little studied and is rarely observed over the ocean. In this work, MeSH was measured at much higher levels than previously observed (3–36 % of parallel DMS mixing ratios). MeSH could be a significant source of atmospheric sulfur over productive regions of the ocean, but its distribution, and its atmospheric impact, requires more investigation.
To many non-specialists, the science behind climate change can appear confusing and alienating, yet in order for global mitigation efforts to be successful it is not just scientists who need to take action, but rather society as a whole. This study shows how poets and poetry offer a method of communicating the science of climate change to the wider society using language that they not only better understand, but which also has the potential to stimulate accountability and inspire action.
Over the next few weeks, we’d like to introduce you to some new faces on the GfGD blog, bringing fresh ideas and perspectives on topics relating to geoscience and sustainable development. We’re delighted to have their input and look forward to their posts. Today we interview Cecilia Reed – a creative earth science communicator and an expert voice and onscreen contributor for the BBC. Tell us about your journey into the Earth Sciences. My journey into the Earth Sciences is …
Well, the world is certainly in a crazy time – one of the most enlightening tweets that I keep thinking about is: In a longer article, Klein asks a crucial question: can social solidarity replicate faster than the virus? So to encourage social solidarity in our dispersed global community of groundwater nerds, I suggested we share: a picture of our #StayAtHomeAndStaySafeView a song that is working for you right now, for our very own ‘pandemic playlist’ (ideally from an artist …
This is a transmitted light microscope image of a thin section – a 50-micron thick sliver of rock. This sample was collected from Jebel Hafit, a mountain which straddles the United Arab Emirates and Oman border. Jebel Hafit is approximately 900 m high and is made up of Eocene to Miocene age carbonate rocks which were mainly deposited in a shallow water, tropical setting. More specifically, this image shows part of a larger benthic foraminifera (LBF). During the Eocene, in …
