Saltwater intrusion from sea level rise and tidal flooding is increasing soil salinity risks in coastal farm fields (Figure 1). Soil salinity is related to the presence of soluble salts and cations ...

Brillouin lidar techniques harness the inelastic scattering of light – known as Brillouin scattering – within seawater to derive key physical parameters, notably temperature and salinity. By analysing ...

Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2023.220016 discusses ocean lidar remote sensing technology based on Brillouin scattering spectrum. The monitoring of marine ...

The paper found that the water in the Southern Ocean has unexpectedly been getting saltier over the last 10 years, a reversal of a trend measured since roughly the 1970s. Its main author told Snopes ...
