A new model quantifies the relative contributions of denitrification and other processes of nitrogen uptake, such as by plants, from groundwater in riparian areas around streams.Read More �
Two specifications of fluid dynamics—taking measurements at a fixed point and following a fluid parcel—are compared for quantifying eddy transport in the ocean.Read More �
The microphysics of the frequent, and frequently positive, lightning of Hokuriku winter clouds was investigated by systematic, in situ observation of individual precipitation particle type and charge.Read More �
Alpine hydropower plants commonly flush sediment that accumulates at intakes, but the associated rapid rise in discharge, turbidity, and streambed instability put aquatic insects at risk.Read More �
A rare atmospheric phenomenon that transports large quantities of water vapor into the coastal watersheds of the western USA is responsible for up to 10–20% of intense snowmelt events in the region.Read More �
The rates at which fault zones “heal” through secondary mineralization have been elusive, but uranium-thorium dating of calcite growth in fault-zone fractures may provide the answer.Read More �
A first usage of principal component analysis on Hubble images of Jupiter’s auroral ovals reveals the most common patterns, and machine learning classification reveals their physical causes.Read More �
Intense boreal forest fires in August 2017 caused smoke plumes that reached record levels in the stratosphere; satellite measurements show that the effects rivaled a moderate volcanic eruption.Read More �
Laboratory experiments and geochemical model suggest that chlorate is very effective to oxidize reducing iron to reddish iron oxides on Mars when liquid water was present on the surface.Read More �
