Image from instruments on SDO, STEREO, and SOHO of the CME that launched from the Sun on 14 October 2014. The CME was observed fromthe Sun all the way to New Horizons at 32 AU, en route to Pluto.
The figure illustrates river water and groundwater interactions at the reach scale (left) and the hyporheic scale (right). These interactions are at the core of a wide
range of major contemporary challenges, including the provision of high-quality drinking water in sufficient quantities, the loss of biodiversity in river ecosystems, or
the management of environmental flow regimes. Brunner et al. [10.1002/2017RG000556] review state of the art approaches in characterizing and modeling river and
groundwater interactions, including remote sensing to characterize the streambed, emerging methods to measure exchange fluxes between rivers and groundwater, and
developments in several disciplines relevant to the river-groundwater interface. These novel approaches show great potential to tackle the most critical water resources
challenges at the watershed scale.

Examples of mud volcanoes that responded to the main earthquakes of the Central
Italy seismic sequence. (a) Satellite image and (b) lateral view show the S.M. in Paganico mud volcano after the
Mw 6.5 earthquake of 30 October.
(c) N-S trending fractures controlling the surface mud extrusion of the Valle Corvone mud volcano after the 30 October earthqua
ke. (d) Lateral view of the newly formed Contrada S. Salvatore mud volcano, which erupted the day after the 30 October earthquake. (e) N-S trending fracture along the so-called Case Tedeschi 2bis mud volcano, a newly formed seep south of the Monteleone di Fermo village. (f ) Stereoplot showing the trend of ground fractures controlling mud volcanism. An average value of N355°±5°E/90° is taken as input parameter for the normal stress
Pictured is a measurement campaign in October 2015 using a portable radar interferometer on the Great Aletsch Glacier in Switzerland. The campaign
The three-dimensional structure of Uranus’ global magnetosphere at solstice, including the upstream solar wind streamlines, the magnetic field lines, and the pressure. The magnetosphere alternates between an open structure and a closed one during rotation, which shows the “switch-like” effect discussed in Cao and Paty.
In Czuba et al. image shows Lidar hillshade highlighting major features (river, bluff, and ravine, each with relevant attributes) incorporated into the model. Inset image shows a 64m bluff; note the canoe for scale. Location and extent is shown in Figure3by a small red box.

Giordani et al. [DOI: 10.1002/2016JC012019], intense surface buoyancy losses (–400 W/m2, colour) occurred under the path of Mistral and Tramontane winds (black arrows, N/m2) in the Gulf of Lion (GL) during the ASICS-MED experiment (February 2013). These buoyancy fluxes and positive Ekman pumping (cyan positive, green negative wind-stress curl used as proxy of the Ekman pumping, N/m3 x 10 5; interval 0.2 x 10–5 N/m3 x 1.105) are key atmospheric conditions for dense water formation (DWF) and preconditioning in the GL. DWF also occurs along the Catalan coast i.e. along the northern branch of the Liguro-Provençal Current where strong horizontal density gradients are present (see brown lines of surface density). DWF results from the coupling between the surface wind stress (black arrows) and lateral buoyancy gradients because this coupling leads to efficient destratification and PV-destruction in frontal regions. As consequence DWF cannot be reduced as a buoyancy flux problem.
(a) Surface-based duct refractivity profile and Cn2 profile. (b) Propagation loss (PL) of 1 GHz wave given refractivity and Cn2 profiles in Figure 1a under no turbulence. PL calculated assuming homogeneous turbulence given (c) Cn2=10−15 and (e) 10−14. PL calculated assuming inhomogeneous turbulence given (d) Cs=10−15 and (f) Cn2=10−14.

The results (in gm-3) are obtained using a newly developed windblown dust scheme implemented in the Community Multiscale Air Quality (CMAQ) modeling system
