Abstract Wetland ecosystems play key roles in global biogeochemical cycling, but their spatial extent and connectivity is often not well known. Here, we detect the coverage type of wetlands at 10 m resolution across southern Nigeria (total area: 147,094 km 2 ), thought to be one most wetland-rich areas Africa. We use Sentinel-1 Sentinel-2 imagery supported by 1500 control points for algorithm t...

-Batch cation-exchange experiments were performed on chlorite, using synthetic ground water containing cesium in the concentration range 10-9-10 -3 M. The sorption behavior was complex; with increasing Cs concentration, the distribution ratio of Cs decreased at first, but passed through a pronounced maximum at high Cs loadings. The desorption data differed from the sorption data only by a shift...

We have observed the Blue Compact Dwarf (BCD) galaxy He 2-10 in the ∼10 µm mid-infrared (MIR) atmospheric window using broad-band filters centered at λ10.1 µm and λ11.65 µm. In both filters, only the galaxy's central regions were detected. One of the UV emitting regions is not detected, implying an older age. The central region contain two resolved components which have the same MIR properties ...
