ExtremeEarth is a three-year H2020 ICT research and innovation project. Its main objective is to develop Artificial Intelligence and big data technologies that scale to the large volumes of big…17 May, 2021 by Andrew Fleming, Andreas Cziferszky
Current deep learning architectures for remote sensing are trained on small datasets typically using 1 GPU without taking advantage of new innovative approaches such as distributed scale-out deep learning. In…Read more on The ExtremeEarth software architecture for Copernicus earth observation data

For many years, it was believed that resonant interactions between electromagnetic ion cyclotron (EMIC) waves and radiation belt electrons were restricted to electron energies > 1 − 2 MeV. In…Read more on Evidence of sub‐MeV EMIC‐driven trapped electron flux dropouts from GPS observations

We propose an operator preconditioner for general elliptic pseudodifferential equations in a domain Ω, where Ω is either in Rn or in a Riemannian manifold. For linear systems of equations…Read more on Optimal operator preconditioning for pseudodifferential boundary problems.

Knowledge of life on the Southern Ocean seafloor has substantially grown since the beginning of this century with increasing ship-based surveys and regular monitoring sites, new technologies and greatly enhanced…13 May, 2021 by Claire Waluda
Microplastics (< 5mm in size) is known to be widespread in the marine environment, but it is still poorly studied in Polar Regions, particularly in the Antarctic. As penguins have…

Sudden Stratospheric Warmings (SSWs) could act as an important mediator in the vertical coupling of atmospheric regions and dramatic variations in the mesosphere and lower thermosphere (MLT) in response to…6 May, 2021 by Peter Convey
Two cyanobacterial morphotypes isolated from Signy Island, South Orkney Islands, maritime Antarctica were characterised using a polyphasic approach combining morphological, cytological and molecular analyses. These analyses showed that the strains…
