Exploration of oxidative chemistry and secondary organic aerosol formation in the Amazon during the wet season:explicit modeling of the Manaus urban plume with GECKO-A

The GoAmazon 2014/5 field campaign took place near the city of Manaus, Brazil, isolated in the Amazon rainforest, to study the impacts of urban pollution on natural air masses. We simulated this campaign with an extremely detailed organic chemistry model to understand how the city would affect the growth and composition of natural aerosol particles. Discrepancies between the model and the measurements indicate that the chemistry of naturally emitted organic compounds is still poorly understood.

Effects of upwelling duration and phytoplankton growth regime on dissolved-oxygen levels in an idealized Iberian Peninsula upwelling system

The oceans are losing oxygen, and future changes may worsen this problem. We performed computer simulations of an idealized Iberian Peninsula upwelling system to identify the main fine-scale processes driving dissolved oxygen variability as well as study the response of oxygen levels to changes in wind patterns and phytoplankton species. Our results suggest that oxygen levels would decrease if the wind blows for long periods of time or if phytoplankton is dominated by species that grow slowly.

Wetropolis extreme rainfall and flood demonstrator: from mathematical design to outreach

Wetropolis is a table-top demonstration model with extreme rainfall and flooding, including random rainfall, river flow, flood plains, an upland reservoir, a porous moor, and a city which can flood. It lets the viewer experience extreme rainfall and flood events in a physical model on reduced spatial and temporal scales with an event return period of 6.06 min rather than, say, 200 years. We disseminate its mathematical design and how it has been shown most prominently to over 500 flood victims.

Rapid collaborative knowledge building via Twitter after significantgeohazard events

Among social media platforms, Twitter is valued by scholars to disseminate scientific information. Using two 2018 geohazard events as examples, we show that collaborative open data sharing and discussion on Twitter promote very rapid building of knowledge. This breaks down the traditional ivory tower of academia, making science accessible to nonacademics who can follow the discussion. It also presents the opportunity for a new type of scientific approach within global virtual teams.

Imaggeo on Mondays: The Grid – A serpentine pseudomorph after carbonate

The structures in this photo might look three-dimensional, but they are completely flat. It is a photo of a polished thinsection of a rock, taken through a petrographic microscope under cross-polarized light. The width of the image is just 2 mm. The brownish mineral around the edges is carbonate, the white to grey mineral in the centre is serpentine, a water-bearing silicate mineral. The different shades of grey are due to different orientations of the crystals in this sample. When …

Our team is growing … unprecedentedly!

Our team is growing … unprecedentedly!

It is my great pleasure to introduce you to our new SSS Early Career Scientist (ECS) & Outreach team. This year, apart from having a new ECS Representative – Layla San Emeterio – we realized that there’s just too much fun for one person! That’s why this year, our division has also elected two ECS Co-representatives: Mika Turunen and Dan Evans. Mika and Dan started immediately helping Layla and I with Twitter and brainstorming about blog content. And that’s not …
