Large contribution of organics to condensational growth and formation of cloud condensation nuclei (CCN) in the remote marine boundary layer
- Atmospheric Chemistry and Physics
- DOI 10.5194/acp-20-12515-2020
- 27 November 2020
Condensational growth of Aitken-mode particles is a major source of cloud condensation nuclei in the remote marine boundary layer. It has been long thought that over remote oceans, condensation growth is dominated by sulfate that derives from ocean-emitted dimethyl sulfide. In this study, we present the first long-term observational evidence that, contrary to conventional thinking, organics play an even more important role than sulfate in particle growth over remote oceans throughout the year.
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.

How many transdisciplinary researchers does it take to find out how an ocean sinks?
- GeoLog – EGU official blog
- posted 5 hours ago
There is no shortage of increasingly uphill challenges in the current research landscape, especially for Early Career researchers: discouragingly long-standing science questions; minimal freedom for developing methodologies; invariably ambivalent proposal reviews; an academic grading scheme based mainly on publication productivity and impact; and enforced competition for few permanent research positions, just to name a few. Despite (or rather, because of) this, in 2018, fourteen international Early Career researchers set out to challenge the traditional structures and approaches, and create a …
Seafloor secrets: traces of the past Patagonian ice sheet
- Cryospheric Sciences
- posted 7 hours ago
Today’s Patagonian ice caps are confined to the high-altitude Andean Mountain range as the Northern and Southern Patagonia ice fields, and they are rapidly melting. The southern part of the Patagonian ice cap drains partially through fast-flowing ice streams into the fjords of Patagonia. Glaciers in this region have been losing ice at accelerating rates by large calving events, due to rising global mean temperatures (see this post). The changes are enormous and have been calculated to contribute 0.048 mm …

Rudi inshtead ashks the not-at-all, definitely-not, who-me, ashking-for-a-friend queshtion: Can I get drunk at Friday Beers? Dear Rudi, Your question has more answers than asking a conference of geodynamicists what’s the best wine? With movement and beer restrictions in place, the question is currently rather academic, but as with many academic problems, still worth considering. If we ever get released, the smell …
