collected alongside other treatments at the end of the column experiment, may have lost some hydrocarbon fractions due to evaporation during the incubation period. This loss in the autoclaved
falls within the range of projected mean annual Arctic air temperature anomalies (3–5 °C) for a global warming threshold of 2 °C (compared to PI). While these numbers are not directly comparable, as one is representative of the whole Arctic, ...

The STRATOLE experiment is designed to study the wintertime Antarctic lower stratosphere polar vortex and its springtime breakdown. To this end, it is planned to fly a large number (around 200) of long-lived (3 months), small isopycnic d... F Vial,A Babiano,B Brioit,... - 《Physics ...
s a less than 10 percent chance the current warming trend could be natural. with the polar year in full swing, no fewer than 200 expeditions with scientists from 60 countries are collecting baseline data in the arctic. every week brings a new study about the breakdown of another component ...
seasonal sea-ice in the southern Lincoln Sea was likely restricted to the near-coastal areas, associated with a thinner more mobile sea-ice cover and the breakdown of the landfast sea-ice cover. In this scenario, a thin ice pack may have survived in the central Lincoln Sea and parts of ...
A breakdown of the internal stress gradient into component parts reveals that the shear viscous force is far from negligible, which casts strong doubt on the theoretical validity of the cavitating fluid approximation (in which this component is neglected). Finally, the role of ice pressure is ...
As permafrost warms or degrades the organic matter that was trapped within the permafrost can be released. Microbial activity can then breakdown this organic matter creating carbon dioxide and methane that can be a source of greenhouse gases to the atmosphere. However, the biogeochemical processes ...
the point at which we'd expect the percentage to drop because of sea ice area dropping faster than extent, or in other words: because the ice pack kept a relative same shape at the exterior, but started to become less concentrated in parts of the interior, as shown by the 'holes' we...
Wind stress controls ice deformation and can destroy ice by mechanical breakdown or forcing warm ocean waters upward. Enhanced transport of ice can lead to ice advection and deformation, lead formation, and ice streamers (e.g., Hoerton et al., 2014), which can have feedbacks on both ...
