Beaching patterns of plastic debris along the Indian Ocean rim
- Ocean Science
- DOI 10.5194/os-16-1317-2020
- 26 November 2020
A large percentage of global ocean plastic enters the Indian Ocean through rivers, but the fate of these plastics is generally unknown. In this paper, we use computer simulations to show that floating plastics beach and end up on coastlines throughout the Indian Ocean. Coastlines where a lot of plastic enters the ocean are heavily affected by beaching plastic, but plastics can also beach far from the source on remote islands and countries that contribute little plastic pollution of their own.
Reviews and syntheses: The mechanisms underlying carbon storage in soil
- Biogeosciences
- DOI 10.5194/bg-17-5223-2020
- 25 November 2020
The 4 per 1000 initiative aims to restore carbon storage in soils to both mitigate climate change and contribute to food security. The French National Institute for Agricultural Research conducted a study to determine the carbon storage potential in French soils and associated costs. This paper is a part of that study. It reviews recent advances concerning the mechanisms that controls C stabilization in soils. Synthetic figures integrating new concepts should be of pedagogical interest.
Global modeling of cloud water acidity, precipitation acidity, and acidinputs to ecosystems
- Atmospheric Chemistry and Physics
- DOI 10.5194/acp-20-12223-2020
- 24 November 2020
Cloud water pH affects atmospheric chemistry, and acid rain damages ecosystems. We use model simulations along with observations to present a global view of cloud water and precipitation pH. Sulfuric acid, nitric acid, and ammonia control the pH in the northern midlatitudes, but carboxylic acids and dust cations are important in the tropics and subtropics. The acid inputs to many nitrogen-saturated ecosystems are high enough to cause acidification, with ammonium as the main acidifying species.
The Making of the New European Wind Atlas – Part 2: Production and evaluation
- Geoscientific Model Development
- DOI 10.5194/gmd-13-5079-2020
- 23 November 2020
This is the second of two papers that document the creation of the New European Wind Atlas (NEWA). The paper includes a detailed description of the technical and practical aspects that went into running the mesoscale simulations and the microscale downscaling for generating the climatology. A comprehensive evaluation of each component of the NEWA model chain is presented using observations from a large set of tall masts located all over Europe.

Geodynamics 101: Dynamic Topography
- Geodynamics
- posted 7 hours ago
The Geodynamics 101 series serves to showcase the diversity of research topics and/or methods in the geodynamics community. In this week’s post, Fred Richards explains how ‘Dynamic Topography’ is used in the Geosciences, and discusses the knowns, unknowns, and the challenges ahead. Since shortly after its tumultuous formation 4.5 billion years ago, Earth has been steadily cooling, with its interior separating into a dense iron-rich core and a silicate mantle. Within the mantle, heat is continuously transported to the surface …

LOESS IN TRANSLATION
- Climate: Past, Present & Future
- posted 1 day ago
Loess is a mineral, aeolian deposit with a range of definitions in literature, which class it as either a sediment, soil, or rock. Some classic texts suggest that “loess is not just the accumulation of dust” [1], and it must include additional processes such as loessification, calcification, pedogenesis, and in-situ weathering. The definition adopted depends on the scientific background and the question being posed, but my preference is to simply define loess as: an aeolian, mineral (i.e. non organic), silt-size …
