Air pollution in New York City linked to wildfires hundreds of miles away
- Press release
- 21 January 2020
A new study published in the European Geosciences Union (EGU) journal Atmospheric Chemistry and Physics shows that air pollutants from the smoke of fires from as far as Canada and the southeastern U.S. traveled hundreds of miles and several days to reach Connecticut and New York City, where it caused significant increases in pollution concentrations.

Modal shift in North Atlantic seasonality during the last deglaciation
- Climate of the Past
- DOI 10.5194/cp-16-265-2020
- 18 February 2020
Here, mid-ocean seasonality is resolved through time, using differences in the oxygen isotope composition between individual shells of the commonly used (sub)polar planktonic foraminifera species in ocean-climate reconstruction, N. pachyderma and G. bulloides . Single-specimen isotope measurements during the deglacial period revealed a surprising bimodality, the cause of which was investigated.
Dimensions of marine phytoplankton diversity
- Biogeosciences
- DOI 10.5194/bg-17-609-2020
- 18 February 2020
Phytoplankton are an essential component of the marine food web and earth’s carbon cycle. We use observations, ecological theory and a unique trait-based ecosystem model to explain controls on patterns of marine phytoplankton biodiversity. We find that different dimensions of diversity (size classes, biogeochemical functional groups, thermal norms) are controlled by a disparate combination of mechanisms. This may explain why previous studies of phytoplankton diversity had conflicting results.
A new look at the environmental conditions favorable to secondary ice production
- Atmospheric Chemistry and Physics
- DOI 10.5194/acp-20-1391-2020
- 13 February 2020
This study attempts identification of mechanisms of secondary ice production (SIP) based on the observation of small faceted ice crystals. It was found that in both mesoscale convective systems and frontal clouds, SIP was observed right above the melting layer and extended to the higher altitudes with colder temperatures. A principal conclusion of this work is that the freezing drop shattering mechanism is plausibly accounting for the measured ice concentrations in the observed condition.
Machine learning and soil sciences: a review aided by machine learning tools
- SOIL
- DOI 10.5194/soil-6-35-2020
- 13 February 2020
The application of machine learning (ML) has shown an accelerated adoption in soil sciences. It is a difficult task to manually review all papers on the application of ML. This paper aims to provide a review of the application of ML aided by topic modelling in order to find patterns in a large collection of publications. The objective is to gain insight into the applications and to discuss research gaps. We found 12 main topics and that ML methods usually perform better than traditional ones.

Ambient seismic noise and the quest for groundwater
- Seismology
- posted 7 hours ago
Groundwater is water stored within permeable geological formations, and nearly a third of Earth’s freshwater supply comes from this source (a). In Africa, the overwhelming majority of distributable freshwater is contained in groundwater, and in the EU, 75% of the population relies on groundwater (b). This dependence on groundwater is steadily rising. As humanity as a whole, figures out how to adapt to the impacts of climate change and population growth on water stress, scientists have projected a 20 – …

On February 9th, a British Airways Boeing 747 landed in London Heathrow airport just four hours and 56 minutes after its take-off in JFK, New York, setting the shortest flight-time for non-supersonic jets over this route. The jumbo jet took advantage of the fast upper-tropospheric winds associated with an exceptionally strong jet-stream which created tail winds of about 400km/h. Over the United Kingdom, the left exit region of the jet helped produce Storm Ciara causing widespread wind and flooding damage …
Imaggeo on Mondays: The sun rises also in the middle of nowhere

Uluru in Australia is one of the most visibly recognisable geological features in the world. This sandstone formation covers an area of 3.3 kilometres and stands 345 metres above the plains around it. Deposited in an inland sea during the Cambrian Period approximately 500 million years ago, the arkose sandstones were uplifted and folded during the Alice Springs Orogeny, between 400 and 300 million years ago, making the formation more resistant to later erosion. Because Uluru is in the middle …
